I want to learn 2 d echo

Reading File

2D echocardiography (2D echo) is a cardiac ultrasound technique that uses sound waves to create real-time cross-sectional images of the heart. It is the most widely used cardiac imaging modality, used to assess chamber size, wall motion, valve function, and pericardial disease.

A Complete Guide to Learning 2D Echocardiography

Based on the Textbook of Clinical Echocardiography (Otto CM, Elsevier)

1. What is 2D Echocardiography?

2D echocardiography (2D echo) uses a phased-array transducer to electronically sweep an ultrasound beam across a tomographic plane, generating real-time cross-sectional images of the heart at ≥30 frames per second. It is the clinical standard for most cardiac indications - assessing chambers, valves, wall motion, pericardium, great vessels, and more.

2. Ultrasound Physics - The Foundation

Before touching a probe, you need to understand why the image looks the way it does.

Ultrasound Waves

Sound waves with frequency >20,000 Hz (cardiac probes: 1-8 MHz)
The fundamental equation: wavelength = speed / frequency (speed in tissue ~1540 m/s)
Higher frequency = better resolution but less penetration
Lower frequency = deeper penetration but less resolution

Tissue Interactions

Interaction	What Happens	Clinical Impact
Reflection	Wave bounces back at a tissue interface	Creates the image signal
Scattering	Irregular reflection from small structures	Creates speckle (grain)
Refraction	Beam bends at an interface	Can cause positioning artifacts
Attenuation	Signal weakens with depth	Requires time-gain compensation (TGC)

The Transducer

Contains piezoelectric crystals that convert electricity to sound and back
Acts as both transmitter and receiver
Pulse Repetition Frequency (PRF): how many pulses per second - limited by imaging depth

3. Image Production - How the 2D Picture is Made

A 2D image is built by sweeping the beam line-by-line across the sector:

A short ultrasound pulse is fired along each scan line
Reflected signals return to the transducer, with:
- Amplitude proportional to angle of incidence and acoustic impedance difference
- Timing proportional to distance from transducer (depth = time x speed/2)
Signals undergo amplification, time-gain compensation (TGC), and gray-scale mapping
All lines are assembled into one image frame

Frame rate vs. quality trade-off:

More scan lines = better image density but slower frame rate
Standard: ≥30 frames/second for cardiac motion (128 scan lines at 20 cm depth)
Cardiac imaging needs high frame rate - do not sacrifice it for width

Key Instrument Controls

Control	What It Does	How to Optimize
Frequency	Sets resolution vs. penetration	Use highest frequency that gives adequate depth
Gain	Overall image brightness	Avoid over-gain (obscures borders) or under-gain (missed echoes)
TGC	Compensates for depth attenuation	Adjust so image is uniformly bright near and far
Depth	How deep the image goes	Set just past the structure of interest
Sector width	Standard 60° sector angle	Narrow it to increase frame rate when needed
Dynamic range	Range of gray shades displayed	Adjust to optimize tissue-to-blood contrast

4. M-Mode vs. 2D vs. 3D

Mode	What It Shows	Best For
M-mode	Depth vs. time along a single line; very high temporal resolution	Valve timing, rapid motion (mitral flutter in AR), precise wall measurements
2D	Real-time cross-sectional tomographic image	Standard clinical imaging, spatial relationships, wall motion
3D	Volumetric dataset; spatial relationships in all planes	Valve anatomy, LV volumes, congenital defects

2D imaging is the clinical standard - M-mode and 3D are used as supplements.

5. Acoustic Windows - Where You Put the Probe

Acoustic windows are areas where sound can reach the heart without being blocked by bone or lung. There are four main transthoracic windows:

Window	Patient Position	Key Views Obtained
Parasternal	Left lateral decubitus	Long-axis (PLAX), short-axis (PSAX), RV inflow/outflow
Apical	Steep left lateral decubitus	4-chamber, 2-chamber, long-axis, 5-chamber
Subcostal	Supine, legs slightly bent	4-chamber, short-axis, IVC view
Suprasternal notch	Supine, neck extended	Aortic arch, descending aorta

6. The Standard Views - Systematic 2D Echo Exam

Parasternal Long-Axis (PLAX)

Position: Left 3rd-4th intercostal space, adjacent to sternum; patient in left lateral decubitus
What you see: Aortic valve, mitral valve, LV (basal/mid), LA, proximal ascending aorta, RV outflow tract, pericardium
Structures NOT seen: Apical LV segments, RV apex
Key measurements: LV wall thickness, LV internal dimension, aortic root diameter, LA diameter

Parasternal Short-Axis (PSAX)

Rotate probe 90° clockwise from PLAX
Sweep from base to apex to visualize different levels:
- Aortic valve level - "Mercedes-Benz" aortic valve, LA, RA, RV, pulmonary valve, MPA
- Mitral valve level - "Fish-mouth" MV opening, LV as circle
- Papillary muscle level - Medial and lateral papillary muscles, LV wall segments
- Apical level - LV tapers to a point

Apical Four-Chamber View (A4C)

Position: Directly over the LV apex; patient in steep left lateral decubitus
What you see: All 4 chambers simultaneously, both AV valves, interatrial septum, interventricular septum
Key uses: LV/RV size and function, mitral/tricuspid valve disease, LV wall motion
Pitfall: Foreshortening - if the LV looks too spherical, move medially until the true apex is seen

Apical Two-Chamber View (A2C)

Rotate probe ~60° counterclockwise from A4C
What you see: LV only (anterior and inferior walls), LA, mitral valve
Used together with A4C for biplane LV volumes (Simpson's method)

Apical Long-Axis View (A-LAX / Apical 3-Chamber)

Rotate another ~60° counterclockwise from A2C
What you see: Aortic valve, mitral valve, LV (inferoseptum and anterolateral wall), LA, aortic root
Equivalent plane to PLAX but from the apex - confirms PLAX findings

The three apical planes are ~60° apart from each other, as shown below:

Apical image planes showing 4-chamber, 2-chamber, and long-axis planes each ~60° apart

Subcostal Views

Subcostal 4-chamber: Excellent for IAS (best view for detecting ASD), when parasternal/apical windows are poor (COPD, post-surgery)
Subcostal short-axis: RV, aortic valve, pulmonary valve, IAS
IVC view: Assess IVC diameter and collapsibility (used to estimate right atrial pressure)

Suprasternal Notch

Aortic arch anatomy, coarctation assessment, descending aorta Doppler

7. Best Views for Each Structure

Structure	Best Views
Aortic valve	PLAX, PSAX, Apical long-axis
Mitral valve	PLAX, PSAX-MV level, A4C, Apical long-axis
Pulmonary valve	PSAX (AV level), RV outflow
Tricuspid valve	RV inflow, A4C, Subcostal 4-chamber
Left ventricle	PLAX, PSAX, A4C, A2C, A-LAX, Subcostal
Right ventricle	RV inflow, PSAX, A4C, Subcostal 4-chamber
Interatrial septum	PSAX, Subcostal 4-chamber (best)
Aortic arch	Suprasternal notch
Descending aorta	Suprasternal notch, PLAX (posterior)

8. Imaging Artifacts - Don't Be Fooled

Artifact	Cause	How to Recognize
Reverberation	Multiple reflections between two strong reflectors	Equally spaced repeated lines
Side lobe artifact	Energy from outside the main beam	Structure appears in wrong location
Shadowing	Calcification or prosthetic material blocks beam	Acoustic shadow behind dense structure
Near-field clutter	Strong reflections near transducer	Blurring close to probe
Cardiac motion artifact	Heart moves during data acquisition	Blurring of moving borders

9. What to Assess Systematically on Every Echo

A complete 2D echo examination covers:

LV size and function - chamber dimensions, wall thickness, regional wall motion, ejection fraction
RV size and function - RV/LV ratio, wall motion, TAPSE
LA and RA size - chamber dimensions
Aortic valve - leaflet number, thickening/calcification, opening, any stenosis/regurgitation signs
Mitral valve - leaflet morphology, motion, prolapse, rheumatic changes
Tricuspid and pulmonary valves
Pericardium - effusion (size, location), tamponade signs (RA/RV collapse)
Aorta - root and ascending diameter, arch
IVC - diameter and respiratory variation (RA pressure estimation)

10. Key Measurements (Normal Values)

Measurement	Normal Range
LV internal dimension (diastole)	≤5.6 cm (men), ≤5.2 cm (women)
LV wall thickness (IVS/PW)	0.6-1.0 cm
Ejection fraction (biplane)	≥55%
LA diameter (PLAX)	≤4.0 cm (men), ≤3.8 cm (women)
Aortic root (sinus of Valsalva)	≤4.0 cm (men), ≤3.6 cm (women)
IVC diameter	≤2.1 cm (collapses >50% with sniff = RA pressure ≤5 mmHg)

11. How to Learn - Practical Pathway

Step 1 - Master physics first (1-2 weeks) Read the physics chapter of a dedicated echo textbook. Understand why artifacts happen.

Step 2 - Learn normal anatomy in each view (2-4 weeks) Use the standard views systematically. Always start PLAX → PSAX → Apical → Subcostal.

Step 3 - Perform supervised scans (ongoing) No substitute for hands-on practice. The apical window is the hardest to find in most patients - practice positioning.

Step 4 - Learn pathology view-by-view Aortic stenosis, mitral regurgitation, LV dysfunction, pericardial effusion - learn how each appears on 2D.

Step 5 - Add Doppler (pulsed-wave, continuous-wave, color, tissue Doppler) 2D gives structure; Doppler gives function and hemodynamics.

Now I have everything needed. Here is the complete, practical reference guide:

Complete Practical 2D Echo Guide: Views, Doppler, Measurements & Reporting

Based on the Textbook of Clinical Echocardiography (Otto CM, Elsevier)

PART 1: THE DOPPLER TOOLKIT - PW, CW, Color, Tissue

Understanding which Doppler mode to use is the single most important practical skill.

Pulsed-Wave (PW) Doppler

How it works: Fires pulses and listens only at a specific depth (the "sample volume"). You place the cursor exactly where you want to measure.

Key property: Range-specific - measures flow at ONE location only.

Limitation: Cannot measure high velocities. Has a maximum velocity limit (Nyquist limit = ½ PRF). Signals above this limit cause aliasing - the waveform wraps around the baseline.

Maximum measurable velocity at typical depths:

At 6 cm depth: ~1 m/s
At 12 cm depth: ~0.6 m/s

When to use PW Doppler:

What to Measure	Sample Volume Placement	View
Mitral inflow (E, A waves)	Tips of mitral leaflets	Apical 4-chamber
LVOT velocity for stroke volume	5 mm proximal to aortic valve in LVOT	Apical 5-chamber or long-axis
Pulmonary vein flow	Right upper pulmonary vein, 1-2 cm into vein	Apical 4-chamber
Hepatic vein flow	Hepatic vein from subcostal	Subcostal
Tricuspid inflow	Tricuspid leaflet tips	Apical 4-chamber
Pulmonary artery flow	Main pulmonary artery	PSAX at AV level

Continuous-Wave (CW) Doppler

How it works: Continuously transmits AND receives. Records ALL velocities along the entire beam length simultaneously.

Key property: No maximum velocity limit - can measure very high velocities (3-6+ m/s). But NO range resolution - cannot tell where along the beam the high velocity originates.

When to use CW Doppler:

Clinical Question	CW Placement	What to Measure
Aortic stenosis severity	Align with aortic jet from apical 5-ch, RV inflow, or right parasternal window	Peak velocity, mean gradient (use modified Bernoulli: ΔP = 4V²)
Mitral regurgitation severity	Align with MR jet from apical 4-ch	Peak MR velocity, VTI of MR jet
Tricuspid regurgitation / PA pressure	Align with TR jet from apical 4-ch	Peak TR velocity → PASP = 4(V_TR)² + RAP
Aortic regurgitation pressure half-time	Align with AR jet from apical long-axis	Deceleration slope, PHT
Mitral stenosis	Align with MS jet from apical 4-ch	Peak and mean gradient, PHT
dP/dt of LV	MR jet, from 1 m/s to 3 m/s	dP/dt = 32 mmHg ÷ time(sec) (normal >1200 mmHg/s)

The Bernoulli principle is the core of CW Doppler:

ΔP (mmHg) = 4 × V² (m/s) If V = 4 m/s → gradient = 4 × 16 = 64 mmHg

Color Doppler Flow Imaging

How it works: Assigns colors to mean velocity direction at every pixel. Red = flow toward transducer. Blue = flow away from transducer. Aliasing causes color reversals (mosaic/turbulent pattern).

When to use Color Doppler:

Use	What to Look For
Screen for regurgitation	Abnormal jet going backwards across a valve
Locate the regurgitant jet for CW alignment	Find the direction of the jet first, then aim CW along it
Estimate regurgitant severity semi-quantitatively	Jet area / LA area (for MR), vena contracta width
Detect shunts (ASD, VSD, PDA)	Abnormal color flow crossing a septum
Detect stenotic jets	Turbulent aliased color signal distal to stenotic valve

Standard color settings: Nyquist limit 50-70 cm/s for low-velocity (intracardiac filling) flows; reduce to 20-30 cm/s for pulmonary vein or hepatic vein flows.

Vena contracta: The narrowest point of a regurgitant color jet just at the valve orifice level.

MR vena contracta ≥7 mm = severe
AR vena contracta ≥6 mm = severe
TR vena contracta ≥7 mm = severe

Tissue Doppler Imaging (TDI)

How it works: Same Doppler principle but measures myocardium motion (low velocity, high amplitude), not blood flow. Uses a small sample volume placed at the mitral annulus.

Placement: Pulsed TDI sample volume at:

Lateral mitral annulus (A4C view)
Medial (septal) mitral annulus (A4C view)
Tricuspid annulus (for RV function)

What TDI measures at the mitral annulus:

Wave	What It Represents	Normal Value
s'	Systolic myocardial velocity (= LV contraction)	≥7 cm/s (septal), ≥9 cm/s (lateral)
e'	Early diastolic relaxation velocity	Septal ≥7 cm/s; Lateral ≥10 cm/s
a'	Late diastolic (atrial contraction) velocity	Variable

The E/e' ratio is the key diastolic filling pressure estimator:

E/e' (average) < 14 = normal LV filling pressure
E/e' (average) ≥ 14 = elevated LV filling pressure (use average of septal and lateral)

PART 2: PRACTICAL STEP-BY-STEP ECHO EXAMINATION

Step-by-Step Protocol for a Complete TTE

STEP 1: Parasternal Long-Axis (PLAX)

Patient: Left lateral decubitus
Probe: 3rd-4th ICS, left sternal border; marker pointing to right shoulder
2D assessment:
- LV size, wall thickness (IVS and PW at chordal level)
- Aortic root: sinus of Valsalva, sinotubular junction, ascending Ao
- LA diameter (AP dimension just above aortic valve level)
- Mitral valve leaflet morphology, mobility, calcification
- Aortic valve leaflets (normal bicuspid vs. tricuspid appearance)
- Posterior pericardium for effusion
M-mode: At mitral leaflet tip level - measure LVIDd, LVIDs, IVSd, PWd
Color Doppler: Sweep across MV and AV for regurgitation

STEP 2: Parasternal Short-Axis (PSAX)

Rotate 90° clockwise from PLAX (marker to left shoulder)
Sweep from base to apex - 3 key levels:

a) Aortic valve level
- Tri/bicuspid AV ("Mercedes-Benz" = tricuspid; "fish-mouth" = bicuspid)
- LA, RA, RV, pulmonary valve, main pulmonary artery, RVOT
- Color: pulmonary regurgitation, tricuspid regurgitation
- PW/CW: pulmonary artery flow, pulmonary stenosis
b) Mitral valve level
- MV "fish-mouth" opening - assess for rheumatic changes (diastolic doming, commissural fusion, thickening)
- LV wall as circular cross-section
- Color: MV regurgitant jet
c) Papillary muscle and apical levels
- 6 LV wall segments (anterior, anterolateral, inferolateral, inferior, inferoseptal, anteroseptal)
- Note any regional wall motion abnormality (RWMA) in each

STEP 3: RV Inflow View (from PLAX - tilt medially and inferiorly)

Best view for tricuspid valve anatomy and RV
CW Doppler: TR jet for PASP estimation

STEP 4: Apical Four-Chamber (A4C)

Patient: Steep left lateral decubitus; probe at PMI
Marker: pointing to left hip (or 3 o'clock)
2D assessment:
- All 4 chambers simultaneously - RV:LV ratio (normal RV < 2/3 LV area)
- LV apical, mid, basal segments (anterior septum, lateral wall)
- Mitral leaflet motion, coaptation
- Tricuspid leaflet motion
- IAS and IVS - intact, dropout?
- LA and RA size
PW Doppler:
- Mitral inflow: Sample volume at mitral leaflet tips - record E wave, A wave, E/A ratio, deceleration time (DT)
- Pulmonary vein: Sample volume 1-2 cm into RSPV - record S, D, Ar waves
TDI: Lateral then septal mitral annulus - record e', a', s'
CW Doppler: TR jet - peak velocity → calculate PASP
Color Doppler: MR jet, TR jet screening

STEP 5: Apical Two-Chamber (A2C)

Rotate probe ~60° counterclockwise from A4C
Shows LV anterior wall and inferior wall + LA
Used for biplane Simpson's EF (combine with A4C)
PW mitral inflow if A4C view is suboptimal

STEP 6: Apical Long-Axis / Three-Chamber (A-LAX)

Rotate another ~60° counterclockwise from A2C
Shows aortic valve, LVOT, LV inferoseptum and anterolateral wall
PW Doppler: Place sample volume 5 mm proximal to aortic valve in LVOT - record LVOT VTI (essential for stroke volume, AVA)
CW Doppler: Aortic stenosis jet - align carefully; also AR jet
Color Doppler: LVOT for AR jet, MV for MR

STEP 7: Apical Five-Chamber (A5C)

Slight anterior tilt from A4C to show the aortic valve and LVOT
Best view for CW alignment through aortic valve
PW for LVOT velocity, CW for aortic stenosis

STEP 8: Subcostal Views

Patient: Supine, knees bent
Subcostal 4-chamber: Best for IAS (ASD detection), RV free wall thickness
Subcostal short-axis: Pulmonary valve, aortic valve level
IVC view: Rotate to sagittal plane - record IVC diameter and inspiratory collapse

IVC Diameter	Collapse with Sniff	Estimated RA Pressure
≤2.1 cm	>50%	3 mmHg (normal range 0-5)
≤2.1 cm	<50%	8 mmHg
>2.1 cm	>50%	8 mmHg
>2.1 cm	<50%	15 mmHg (range 10-20)

STEP 9: Suprasternal Notch

Aortic arch, brachiocephalic vessels
CW/PW Doppler in descending aorta for coarctation

PART 3: KEY MEASUREMENTS AND CALCULATIONS

LV Systolic Function

Step 1 - Linear dimensions (PLAX, M-mode at chordal level):

LVIDd (end-diastole) and LVIDs (end-systole)
IVS thickness and PW thickness at end-diastole
Fractional shortening (FS) = (LVIDd - LVIDs)/LVIDd × 100 → Normal ≥25%

Step 2 - Biplane Simpson's EF (gold standard 2D method):

Trace LV endocardium at END-DIASTOLE and END-SYSTOLE in A4C and A2C
EF = (EDV - ESV)/EDV × 100
Normal EF ≥55%; Mildly reduced 45-54%; Moderately reduced 35-44%; Severely reduced <35%

Step 3 - Doppler stroke volume and cardiac output:

LVOT diameter measured in PLAX (systole, inner edge to inner edge)
LVOT VTI traced from PW Doppler in A-LAX or A5C
SV = π(LVOT D/2)² × VTI_LVOT
CO = SV × HR; Normal CO 4-8 L/min; Normal CI >2.5 L/min/m²

PART 6: WHICH DOPPLER TO USE - QUICK DECISION GUIDE

QUESTION TO ANSWER → WHICH DOPPLER

Low velocity, need exact location?         → PW (mitral inflow, LVOT, PV flow)
High velocity, need exact pressure gradient? → CW (AS, MR, TR, AR, MS)
Where is the jet going?                     → COLOR (screen, locate, guide CW)
Is the myocardium moving normally?           → TISSUE DOPPLER (e', s', diastology)
Need to know CO / stroke volume?            → PW for LVOT VTI + 2D for LVOT diameter
Need PA pressure?                          → CW on TR jet + IVC for RAP
Grading MR severity?                       → Color (vena contracta) + CW (VTI) + PISA

PART 7: PRACTICAL TIPS FOR BEGINNERS

Always start with 2D, then add color, then add PW/CW - never start with Doppler without knowing where things are
The apical window is your Doppler window - all inflow/outflow flows are best measured from apical views because the beam is parallel to flow
Align CW carefully before measuring - a 20° angle error causes ~6% velocity underestimation, which squares to a 12% pressure error using the Bernoulli equation
Always check the TR jet from multiple windows - right parasternal, subcostal, and apical views; the highest velocity found is the correct one to use
Measure LVOT diameter accurately - errors here square in the continuity equation. Measure in PLAX, inner edge to inner edge, in systole, at the level of aortic annulus
E/e' is just one of four diastolic criteria - use all four (E/e', TR velocity, LA volume index, mitral E/A pattern) before grading diastolic dysfunction
Report what you see even if normal - a good echo report documents normal structures explicitly, not just abnormalities

*- Textbook of Clinical Echocardiography (Otto CM, Elsevier, 9780323882088)*This is the complete practical 2D echo guide. Here's a summary of what's covered:

What this guide covers:

Part 1 - The Doppler Toolkit

PW Doppler: Range-specific, low velocities - mitral inflow, LVOT VTI, pulmonary veins. Max ~1 m/s at 6 cm
CW Doppler: No range limit, high velocities - aortic stenosis, TR jet for PASP, MR for dP/dt. Uses ΔP = 4V²
Color Doppler: Shows WHERE flow is going, screens for regurgitation, guides CW beam alignment
Tissue Doppler: Measures myocardial motion at the annulus - e', s', a' - key for diastolic function (E/e' ratio)

Part 2 - Step-by-step exam (PLAX → PSAX 3 levels → A4C → A2C → A-LAX → Subcostal → Suprasternal) with what 2D, color, PW, and CW to do at each window

Part 3 - Calculations - Simpson's EF, CO/SV formula, diastolic grading (4-variable algorithm), PASP, AS grading (continuity equation), MS (PHT), MR (PISA/vena contracta), RV function (TAPSE)

Part 4 - Report writing - full template with example language for each section

Part 5 - Normal values quick card - all chambers, Doppler values, pressures in one table

Part 6 - Which Doppler quick decision chart

Textbook of Clinical Echocardiography, Otto CM (Elsevier)

HOW TO USE THIS GUIDE

For every view, the workflow is always:

2D orientation → M-mode measurements (where applicable) → Color Doppler screen → PW Doppler (low velocity) → CW Doppler (high velocity / gradients) → Tissue Doppler (where applicable)

Doppler Toolkit Quick Reference:

Tool	Use for	Limit
PW	Exact location, low velocity	Cannot measure >1-1.5 m/s cleanly
CW	High velocity gradients, no depth info	Use ΔP = 4V²
Color	Locate jets, screen for regurgitation, guide CW	Mean velocity only
TDI (Tissue Doppler)	Myocardial motion, diastology	Angle-dependent
M-mode	Precise dimensions, timing, rapid motion	Single line only

VIEW 1: PARASTERNAL LONG-AXIS (PLAX)

Patient position: Left lateral decubitus, left arm under pillow Probe position: Left 3rd-4th intercostal space, just left of sternum Probe marker: Toward right shoulder (10-11 o'clock)

Anatomy - What You See

PLAX cardiac anatomy diagram - LV, Ao, LA, RV outflow tract, mitral and aortic valves labeled

Normal PLAX 2D echo image in diastole and systole showing LV, Ao, LA

Near field (top of image): RV outflow tract Middle: Interventricular septum (IVS), LV cavity, posterior wall (PW) Right side: Aortic valve (right and noncoronary cusps), aortic root, ascending Ao, LA Bottom left: LA, posterior pericardium, descending thoracic aorta (behind LA) Valves visible: Aortic valve (anterior = right cusp, posterior = noncoronary cusp), Mitral valve (anterior leaflet = long, posterior = short)

PLAX: Step-by-Step Toolkit

STEP 1 - 2D Assessment

LV size: does it look dilated/hypertrophied?
Wall motion: IVS and posterior wall - do they thicken in systole?
Aortic valve: 3 cusps visible? Thickened/calcified/restricted? Bicuspid (look in systole - 2 commissures)?
Mitral valve: leaflet thickness, mobility, prolapse (posterior displacement >2mm past annular plane)?
Pericardium: any posterior effusion?
Descending aorta: visible behind LA as circular structure

STEP 2 - M-Mode (place cursor at level of mitral leaflet tips, perpendicular to LV long-axis)

LVIDd (end of diastole = peak of R wave on ECG) and LVIDs (end of systole = smallest cavity)
IVS thickness and PW thickness at end-diastole
Fractional shortening = (LVIDd - LVIDs) / LVIDd × 100 (Normal ≥25%)
M-mode of aortic valve: assess leaflet separation, check for reduced opening (AS)
M-mode of mitral valve: E and F points, EF slope (reduced in MS)

STEP 3 - Color Doppler

Sweep color box over aortic valve: look for aortic regurgitation (blue jet from AV into LVOT in diastole)
Sweep over mitral valve: look for MR (blue/mosaic jet into LA in systole)
Narrow the color box to improve frame rate

STEP 4 - Measurements from PLAX

Measurement	Where	Normal
LVOT diameter	From inner edge to inner edge, just below AV in systole	1.8-2.4 cm
Aortic annulus	Inner edge to inner edge at hinge points	Men ≤2.6 cm
Aortic sinus of Valsalva	Widest point of sinuses	Men ≤4.0 cm
Sinotubular junction	Where sinuses taper to tubular aorta	-
LA AP diameter	From posterior Ao wall to posterior LA wall, at AV level, at end-systole	Men ≤4.0 cm
LVIDd / LVIDs	M-mode at chordal level	LVIDd ≤5.8 cm (M)
IVS / PW	End-diastole	0.6-1.0 cm

WHAT TO REPORT FROM PLAX:

LV size (normal/dilated), wall thickness (normal/hypertrophied), aortic root measurements, LA AP diameter, qualitative assessment of aortic and mitral valve morphology, presence of pericardial effusion, LVOT diameter for future calculations.

VIEW 2: RV INFLOW VIEW

From PLAX: Tilt probe inferiorly and medially (toward patient's right hip) Probe marker: Toward right shoulder still

Anatomy

What you see: RV, RA, tricuspid valve (anterior + septal leaflets), IVC ostium, coronary sinus

RV Inflow: Step-by-Step Toolkit

STEP 1 - 2D: Tricuspid valve leaflet morphology, RA/RV size, any masses

STEP 2 - Color Doppler: Tricuspid regurgitation jet (systole): locate its direction

STEP 3 - CW Doppler: Align cursor with TR jet direction, obtain peak TR velocity

PASP = 4 × (V_TR)² + RAP (RAP estimated from IVC - see subcostal view)

WHAT TO REPORT: Peak TR velocity, estimated RVSP/PASP, tricuspid valve morphology

VIEW 3: PARASTERNAL SHORT-AXIS - AORTIC VALVE LEVEL (PSAX-AV)

From PLAX: Rotate probe 90° clockwise → marker to left shoulder (1-2 o'clock) Then tilt probe superiorly (toward patient's right shoulder)

Anatomy

PSAX AV level - R, N, L cusps of AV, RVOT, PA, RA, LA, SVC, TV labeled

What you see: Aortic valve in center (R/N/L cusps), surrounding structures:

Anterolateral: RVOT, pulmonary valve, main PA
Right: RA, tricuspid valve
Posterior: LA, LA appendage

PSAX-AV Level: Step-by-Step Toolkit

STEP 1 - 2D Assessment

Count AV cusps in systole (2 = bicuspid; 3 = normal trileaflet)
Normal systolic appearance = near-circular orifice; diastolic = Y-shaped closure
Bicuspid valve: 2 commissures in systole (one cusp larger, may have raphe)
Pulmonary valve: usually 1-2 leaflets visible; assess for PS/PR
RV size and RVOT wall motion
Left and right coronary artery ostia often visible

STEP 2 - Color Doppler

Over AV: AR in diastole (blue jet into RVOT/right of AV origin)?
Over RVOT/PV: pulmonary regurgitation jet (diastole); pulmonic stenosis jet (systole)
Over tricuspid: TR jet

STEP 3 - PW Doppler

Place sample volume in main pulmonary artery (just distal to pulmonary valve)
Normal PA peak velocity < 1.5 m/s; acceleration time >100 ms
Short acceleration time (<70 ms) suggests pulmonary hypertension

STEP 4 - CW Doppler (if PS suspected): aim through PV, measure peak velocity

WHAT TO REPORT: AV leaflet number and morphology, RVOT appearance, PA flow velocity, any pulmonic stenosis/regurgitation

VIEW 4: PARASTERNAL SHORT-AXIS - MITRAL VALVE LEVEL (PSAX-MV)

From PSAX-AV: Tilt probe slightly toward patient's feet (inferior angulation)

Anatomy

What you see: LV as circle, anterior mitral leaflet (long, curved) and posterior MV leaflet (short, P1-P2-P3 scallops); RV anteriorly. In diastole: "fish-mouth" opening.

PSAX-MV Level: Step-by-Step Toolkit

STEP 1 - 2D Assessment

MV opening area: "fish-mouth" - normal large circular opening
Rheumatic MS: reduced opening, thickening, commissural fusion (hockey-stick deformity from PLAX confirms)
Mitral valve prolapse: difficult to assess here; better in PLAX/A4C
Planimetry of MVA: in MS, trace inner edge of valve opening in mid-diastole (= MVA by planimetry, most accurate if adequate image)

STEP 2 - Color Doppler

MR jet: locate origin, direction, vena contracta
The MV short-axis view helps identify which scallop is involved in MR origin

WHAT TO REPORT: MV leaflet morphology, commissural fusion, any prolapse, planimetry MVA if stenosis suspected

VIEW 5: PARASTERNAL SHORT-AXIS - PAPILLARY MUSCLE LEVEL (PSAX-PM)

From PSAX-MV: Tilt probe further toward feet

Anatomy

PSAX PM level - LV circle with medial and lateral papillary muscles, RV anteriorly

What you see: LV as circle with 2 papillary muscles (anterolateral and posteromedial), RV crescent anteriorly. 6 myocardial segments visible.

PSAX-PM Level: Step-by-Step Toolkit

STEP 1 - 2D Assessment (most important level for wall motion) Assess 6 LV wall segments clockwise from top:

Anterior (LAD territory)
Anterolateral (LCx territory)
Inferolateral (LCx/RCA)
Inferior (RCA)
Inferoseptal (RCA/LAD)
Anteroseptal (LAD)

Normal: all segments thicken and move inward in systole Abnormal: hypokinesis (reduced), akinesis (absent), dyskinesis (paradoxical outward)

STEP 2: Note D-shaped septum (flattening of IVS) = RV volume or pressure overload

WHAT TO REPORT: Regional wall motion by segment, papillary muscle morphology, D-sign if present

VIEW 6: APICAL FOUR-CHAMBER (A4C)

Patient: Steep left lateral decubitus; find PMI by palpation Probe: At cardiac apex; marker toward 3 o'clock (toward left hip) Key: Avoid foreshortening - LV should be elongated and pointed at apex

Anatomy

Apical 4-chamber view - all 4 chambers, mitral and tricuspid valves, IAS, IVS in diastole and systole

What you see: LV (right side of screen), LA (far right), RV (left side of screen), RA (far left), MV, TV, IVS, IAS. Both atria at bottom. Both ventricles at top. Moderator band in RV near apex.

A4C: Step-by-Step Toolkit - Most Important View

STEP 1 - 2D Assessment

LV size and shape: elongated ellipse (not spherical - foreshortening)
LV wall motion: anterolateral wall, apex, inferoseptum
LA size (biplane volume)
RV size: RV/LV ratio (normal <0.6); triangular RV vs. dilated rounded
IAS and IVS: intact? Dropout (ASD)?
MV morphology: thickening, prolapse (posterior displacement), coaptation
TV morphology: displacement (Ebstein's), vegetation, prolapse
Pericardial effusion: circumferential or posterior

STEP 2 - Biplane Simpson's EF Tracing

Freeze in end-diastole (largest LV - onset of QRS)
Trace LV endocardium (exclude papillary muscles)
Freeze in end-systole (smallest LV)
Trace again
Repeat in A2C (60° rotated) → machine calculates biplane EF

STEP 3 - Color Doppler (A4C is your screening view)

MR: systolic jet from MV into LA - note direction, size, vena contracta
TR: systolic jet from TV into RA
ASD: any color jet crossing IAS

STEP 4 - PW Doppler: Mitral Inflow (CRITICAL)

Sample volume: AT mitral leaflet tips in diastole
Record: E wave (early diastolic filling), A wave (atrial contraction), E/A ratio, deceleration time (DT)
Also record: IVRT (isovolumic relaxation time) = time from aortic valve closure to MV opening

Normal mitral inflow values:

Parameter	Normal (age 20-60)
E wave	60-100 cm/s
A wave	50-80 cm/s
E/A ratio	0.8-2.0
DT	160-240 ms
IVRT	60-100 ms

STEP 5 - PW Doppler: Pulmonary Vein Flow

Sample volume: 1-2 cm into right upper pulmonary vein (seen in far field posterior to LA, medial corner of A4C)
Record: S wave (systolic), D wave (diastolic), Ar wave (atrial reversal at atrial contraction)
Normal: S ≥ D; Ar duration <35 ms; Ar velocity <35 cm/s
Elevated LA pressure: S < D; Ar velocity >35 cm/s, Ar duration > mitral A wave duration

STEP 6 - Tissue Doppler Imaging (TDI): Mitral Annulus

Place pulsed TDI sample volume at lateral mitral annulus (where LV lateral wall meets MV annulus)
Record: s' lateral (systolic), e' lateral (early diastolic), a' lateral (atrial)
Move sample volume to septal mitral annulus (IVS at MV annulus)
Record: s' septal, e' septal, a' septal

TDI Value	Normal
s' lateral	≥9 cm/s
e' lateral	≥10 cm/s
s' septal	≥7 cm/s
e' septal	≥7 cm/s
E/e' average	<14 = normal filling pressure

STEP 7 - CW Doppler: TR Jet

Align with TR jet from A4C
Peak TR velocity → PASP = 4(V_TR)² + RAP
Also: MR jet if present - used for dP/dt = 32 / time from 1→3 m/s (normal >1200 mmHg/s)

STEP 8 - RV Function: TAPSE

Place M-mode cursor through tricuspid annulus (lateral point) in A4C
Measure excursion from end-diastole to end-systole
Normal TAPSE ≥17 mm; <17 mm = reduced RV systolic function
TDI: place sample at TV lateral annulus → s' ≥9.5 cm/s

WHAT TO REPORT: EF (biplane), regional wall motion, LV/RV size, mitral E/A/DT, E/e' ratio, LA volume, PASP, TAPSE, TR velocity, any valvular abnormalities, LA volume index

VIEW 7: APICAL TWO-CHAMBER (A2C)

From A4C: Rotate probe ~60° counterclockwise (marker toward 12 o'clock / patient's head)

Anatomy

What you see: LV only - anterior wall (right screen) and inferior wall (left screen), LA, MV. No RV visible. If RV visible, you have not rotated enough.

A2C: Step-by-Step Toolkit

STEP 1 - 2D: LV anterior and inferior wall motion (different coronary territories from A4C)

Anterior: LAD territory
Inferior: RCA territory

STEP 2 - Biplane EF: Trace LV endocardium in end-diastole and end-systole for biplane Simpson's (pairs with A4C)

STEP 3 - Color Doppler: MR jet - may show different aspect of jet compared to A4C

WHAT TO REPORT: Used together with A4C for EF calculation; inferior wall motion assessment

VIEW 8: APICAL LONG-AXIS / THREE-CHAMBER (A-LAX)

From A2C: Rotate another ~60° counterclockwise (marker toward ~10 o'clock)

Anatomy

What you see: LV, aortic valve, LVOT, ascending aorta, LA, RVOT. The apical counterpart of PLAX - same structures but viewed from apex.

LV wall segments visible: Inferoseptum (left screen) and anterolateral wall (right screen)

A-LAX: Step-by-Step Toolkit - KEY DOPPLER VIEW

STEP 1 - 2D: Confirm aortic valve morphology (complements PLAX), LVOT, MV

STEP 2 - PW Doppler: LVOT Velocity (CRITICAL)

Sample volume: 5 mm proximal to aortic valve leaflets, in the center of LVOT
Record LVOT systolic flow envelope → trace VTI (velocity-time integral)
LVOT VTI (normal 18-22 cm) - essential for stroke volume and AVA calculations

STEP 3 - CW Doppler: Aortic Valve (CRITICAL)

Align cursor through aortic valve into ascending aorta (continuous beam)
Record peak aortic velocity, mean gradient
Normal peak Ao velocity < 2.0 m/s
AS: peak ≥4 m/s (severe), ΔP mean ≥40 mmHg (severe)
Continuity equation: AVA = (π × LVOT r²) × VTI_LVOT / VTI_AS

STEP 4 - CW Doppler: Aortic Regurgitation (AR)

AR jet points INTO LV from AV in diastole: dark band below baseline in A-LAX CW
Measure AR jet deceleration slope (pressure half-time):
- PHT <200 ms = severe AR (rapid pressure equalization)
- PHT >500 ms = mild AR

STEP 5 - Color Doppler

AR jet: from AV into LVOT - blue, may alias; measure vena contracta
MR jet: into LA

WHAT TO REPORT: LVOT VTI, LVOT diameter, aortic jet velocity/mean gradient, AVA (continuity equation), AR PHT, AR vena contracta

VIEW 9: APICAL FIVE-CHAMBER (A5C)

From A4C: Tilt probe anteriorly (toward sternum) to bring LVOT and AV into view

What you see: Same as A4C plus aortic valve and LVOT in the center

A5C: Step-by-Step Toolkit

STEP 1 - PW Doppler: Place sample volume in LVOT (5mm below AV) - excellent alignment STEP 2 - CW Doppler: Best view for measuring AS jet in many patients - try all apical windows and use the highest velocity found (right parasternal window also very useful for AS)

VIEW 10: SUBCOSTAL FOUR-CHAMBER

Patient: Supine, knees bent to relax abdomen Probe: Subxiphoid, angled toward heart, marker to patient's left

Anatomy

Subcostal 4-chamber view - all 4 chambers, IAS perpendicular to beam in diastole and systole

What you see: All 4 chambers. RV at top, LV deeper. IAS is now perpendicular to the ultrasound beam - this is the BEST view for ASD detection.

Subcostal 4C: Step-by-Step Toolkit

STEP 1 - 2D: RV free wall thickness (normal ≤5 mm), IAS integrity, IVS STEP 2 - Color Doppler: Color over IAS - look for shunting (ASD/PFO: red or blue jet crossing septum) STEP 3: Used as alternative when parasternal/apical windows are poor (COPD, obese, post-surgery)

VIEW 11: SUBCOSTAL IVC VIEW

From subcostal 4C: Rotate probe 90° to show IVC in long axis entering RA

IVC: Step-by-Step Toolkit

STEP 1 - 2D: Measure IVC diameter 1-2 cm from RA junction at end-expiration STEP 2 - Respiration: Ask patient to sniff - observe collapse

IVC Diameter	Collapse with Sniff	RA Pressure Estimate
≤2.1 cm	>50%	3 mmHg (0-5 normal)
≤2.1 cm	<50%	8 mmHg (5-10)
>2.1 cm	>50%	8 mmHg (5-10)
>2.1 cm	<50%	15 mmHg (10-20)

STEP 3 - PW Doppler: Hepatic vein Doppler from central hepatic vein - S>D normally; S<D or systolic reversal = elevated RA pressure or TR

WHAT TO REPORT: IVC diameter and collapsibility, estimated RA pressure

VIEW 12: SUPRASTERNAL NOTCH

Patient: Supine, neck extended, head turned slightly left Probe: Suprasternal notch; marker toward right shoulder

What you see: Aortic arch, ascending Ao, descending Ao, right pulmonary artery below arch, LA sometimes visible

Suprasternal Notch: Step-by-Step Toolkit

STEP 1 - 2D: Aortic arch anatomy, ascending Ao diameter STEP 2 - Color Doppler: Arch flow; aliasing in descending Ao at coarctation site STEP 3 - CW Doppler: In descending Ao or ascending Ao - used for coarctation assessment STEP 4 - PW Doppler: Descending Ao flow (used for AR regurgitant fraction - holodiastolic flow reversal = severe AR)

THE DOPPLER TOOLKIT - DETAILED AT-A-GLANCE

PW Doppler: Where to Place the Sample Volume

View	Sample Volume Location	What You Measure
A4C	MV leaflet tips	E, A, DT (mitral inflow)
A4C	Right upper pulmonary vein, 1-2 cm in	S, D, Ar (PV flow)
A4C	Lateral MV annulus (TDI mode)	e', s', a' lateral
A4C	Septal MV annulus (TDI mode)	e', s', a' septal
A-LAX / A5C	5 mm below AV in LVOT	LVOT VTI (for SV, CO, AVA)
PSAX-AV	Main PA, just distal to PV	PA flow, acceleration time
A4C	TV lateral annulus (TDI mode)	RV s', e' (TAPSE alternative)
Subcostal	Central hepatic vein	Hepatic vein S, D, AR flow

CW Doppler: Where to Aim and What to Calculate

What to Measure	Best View	CW Position	Calculation
Aortic stenosis peak gradient	A5C, A3C, A4C, right parasternal	Through AV into Ao	ΔP = 4V²
Aortic stenosis AVA	A-LAX (PW first for LVOT VTI) + CW for AV VTI	Continuity equation	AVA = CSA_LVOT × VTI_LVOT / VTI_AV
Aortic regurgitation PHT	A-LAX	Along AR jet (into LV)	PHT; MVA-equivalent AR severity
Mitral stenosis gradient	A4C	Along MS jet into LV	ΔPmean; MVA = 220/PHT
Mitral regurgitation	A4C, A2C	Along MR jet into LA	Peak V (normal 5-6 m/s); dP/dt
TR peak velocity (for PASP)	A4C, RV inflow, subcostal	Along TR jet into RA	PASP = 4(V_TR)² + RAP
LV dP/dt	A4C	MR jet	32 mmHg ÷ time(1→3 m/s); normal >1200 mmHg/s
Pulmonary stenosis	PSAX, subcostal	Along PS jet into PA	ΔP = 4V²; normal PV Vmax <1.5 m/s

DIASTOLIC FUNCTION: THE 4-CRITERIA ALGORITHM

All four criteria must be evaluated in every echo:

Criterion	Measurement	Abnormal Cut-off
1. Septal/lateral e'	TDI at MV annulus	Septal e' <7 cm/s OR lateral e' <10 cm/s
2. E/e' ratio (average)	Mitral E / average e'	≥14 suggests elevated LVEDP
3. LA volume index	Biplane LA volume / BSA	≥34 mL/m² abnormal
4. TR peak velocity	CW on TR jet	>2.8 m/s abnormal

Grade Diastolic Dysfunction:

All normal → Grade 0 (normal diastolic function)
e' reduced but E/A <0.8 and E ≤50 cm/s → Grade I (impaired relaxation)
e' reduced AND ≥2 of remaining 3 criteria met → Grade II (pseudonormal; elevated filling pressure)
E/A >2.0, DT <160 ms → Grade III (restrictive filling; severely elevated filling pressure)

*- Textbook of Clinical Echocardiography, Otto CM, Elsevier (ISBN 9780323882088)*This is the complete illustrated practical guide. Here's what it covers:

12 standard views with anatomy images + step-by-step Doppler toolkit for each:

View	Key Toolkit Steps
PLAX	M-mode dimensions, Color for AR/MR, LVOT diameter measurement
RV Inflow	CW for TR jet → PASP calculation
PSAX-AV	2D for AV cusp number, Color + PW for pulmonary valve
PSAX-MV	2D "fish-mouth" opening, planimetry MVA in stenosis
PSAX-PM	6-segment wall motion analysis, D-sign for RV overload
A4C	Biplane EF, PW mitral inflow, PW pulmonary vein, TDI e'/s', CW TR, TAPSE
A2C	Biplane EF pair with A4C, inferior/anterior wall
A-LAX	PW LVOT VTI, CW aortic stenosis + AR PHT, continuity equation AVA
A5C	Best CW alignment for AS
Subcostal 4C	Color for ASD/PFO (IAS perpendicular to beam)
Subcostal IVC	IVC diameter + sniff test → RA pressure table
Suprasternal	Aortic arch, coarctation, AR holodiastolic reversal

Plus: PW sample volume locations table, CW calculation table, diastolic function 4-criteria algorithm with grading, full echo report template you can use directly, and complete normal values quick-reference card.
