GAPS IDENTIFIED - What Is MISSING from the PPT
1. AUSCULTATION (Most Critical Gap)
The PPT introduces auscultation headings (slides 7-8) but has no detailed slide content on any of the following, which are high-yield for OSCE/CBDC:
A. Heart Sounds in Detail
S1 (First Heart Sound) - "LUB"
- Caused by closure of mitral (M1) and tricuspid (T1) valves at start of systole
- Best heard at apex (mitral area) with diaphragm
- Loud S1: Mitral stenosis (early, mobile leaflet), short PR interval, tachycardia, hyperdynamic states
- Soft S1: Late MS (calcified leaflet), long PR interval, LV dysfunction, beta-blockers, pericardial effusion, obesity
- Variable S1: Atrial fibrillation, complete heart block
S2 (Second Heart Sound) - "DUB"
- Closure of aortic (A2) and pulmonary (P2) valves at end of systole
- Splitting of S2:
- Normal (physiological): A2 before P2; gap widens with inspiration, narrows with expiration
- Wide splitting: RBBB, pulmonary stenosis, pulmonary hypertension, MR (premature A2)
- Fixed splitting: ASD (secundum) - does NOT change with respiration
- Reversed/Paradoxical splitting: LBBB, RV pacing, severe AS, HOCM - P2 before A2; widens on expiration
- Loud P2: Pulmonary arterial hypertension (P2 > A2 at base; palpable at left 2nd ICS)
S3 (Third Heart Sound) - Ventricular gallop
- Low-pitched, early diastole, due to rapid passive ventricular filling
- Best heard at apex with bell, patient in left lateral decubitus
- Pathological in adults: heart failure (LV volume overload), dilated cardiomyopathy, MR, VSD
- Normal in children and young adults
S4 (Fourth Heart Sound) - Atrial gallop
- Low-pitched, late diastole (pre-systolic), due to atrial contraction into a stiff ventricle
- Best heard at apex with bell
- Causes: HTN with LVH, AS, HOCM, myocardial ischemia, acute MI
- Never present in atrial fibrillation (no atrial contraction)
Opening Snap (OS)
- High-pitched early diastolic sound
- Heard at apex/lower LSB with diaphragm
- Occurs in mitral stenosis (mobile leaflet)
- A2-OS interval: short = severe MS; long = mild MS
- Distinguished from P2 by: earlier timing, heard at lower LSB and apex (P2 at 2nd LICS)
Ejection Clicks (EC)
- High-pitched early systolic sounds
- Aortic EC (best heard at RICS 2nd space): bicuspid aortic valve, aortic root dilatation - does NOT change with respiration
- Pulmonary EC (2nd LICS): congenital PS, pulmonary root dilatation - diminishes with inspiration (unique)
B. Murmur Analysis - Full OSCE Checklist
The PPT lists 10 murmur parameters (Slide 8) as headings only. Each needs detail:
| Parameter | What to Assess |
|---|
| Timing | Systolic (early, mid, late, pan/holo), Diastolic (early, mid = rumble, pre-systolic), Continuous |
| Grade (Levine Scale) | I = barely audible; II = soft but clearly heard; III = moderate, no thrill; IV = loud + thrill; V = very loud, heard with stethoscope edge; VI = heard without stethoscope |
| Quality | Harsh (AS), blowing (MR, AR), rumbling (MS), machinery (PDA), musical |
| Pitch | High (AR, MR - diaphragm) vs Low (MS - bell) |
| Configuration | Crescendo, decrescendo, crescendo-decrescendo (diamond), plateau (pansystolic) |
| Radiation | AS → neck/carotids; MR → axilla; VSD → right sternal border; AR → LSB downwards |
| Position changes | Sitting forward in expiration = AR, Pericardial rub; Left lateral decubitus = MS; Squatting = louder (HOCM, MR); Standing = softer MR, louder HOCM |
| Breath | Inspiration increases right-sided murmurs (Carvallo's sign); Expiration accentuates left-sided |
| Diaphragm vs Bell | Diaphragm: high-frequency (MR, TR, AR); Bell: low-frequency (MS, TS, S3, S4) |
Dynamic Auscultation (Maneuvers for OSCE):
- Valsalva (strain phase): Decreases most murmurs EXCEPT HOCM (louder) and MVP (earlier, louder)
- Squatting → Standing: Decreases HOCM (louder on standing); Increases most others
- Handgrip: Increases MR, AR, VSD; decreases HOCM, AS
- Amyl nitrite: Increases AS, HOCM; decreases MR, AR
C. Specific Murmur Recognition (Very High Yield for CBDC/OSCE)
| Murmur | Timing | Best Heard | Quality | Radiation | Special Feature |
|---|
| Mitral Stenosis (MS) | Mid-diastolic rumble + pre-systolic accentuation | Apex, bell, left lateral decubitus | Rumbling | None | Opening snap precedes; loud S1 |
| Mitral Regurgitation (MR) | Pansystolic | Apex, diaphragm | Blowing | Axilla / left infrascapular | Decreases with Valsalva |
| Aortic Stenosis (AS) | Ejection systolic (crescendo-decrescendo) | 2nd RICS → right carotid | Harsh, rough | Neck/carotids | Slow rising pulse, soft A2; radiation is key |
| Aortic Regurgitation (AR) | Early diastolic | Left 3rd/4th ICS, sitting forward in expiration | Blowing | LSB downward | Collapsing pulse; Austin Flint murmur at apex |
| Tricuspid Regurgitation (TR) | Pansystolic | Left lower sternal border | Blowing | None | Increases on inspiration (Carvallo's sign) |
| Pulmonary Stenosis (PS) | Ejection systolic | 2nd LICS | Harsh | Left shoulder | Pulmonary click diminishes on inspiration |
| VSD | Pansystolic | Left 3rd-4th ICS | Harsh | Right sternal border | Thrill common |
| PDA | Continuous "machinery" | Left subclavicular/2nd LICS | Machine-like | None | Heard through systole into diastole |
| Innocent murmur | Systolic ejection | 2nd-3rd LICS | Soft, musical | None | Grade ≤II, no radiation, normal S2, varies with position |
2. PERIPHERAL VASCULAR EXAMINATION (Missing)
Upper limb:
- Allen's test (radial and ulnar patency)
- Capillary refill time (normal < 2 sec)
- Temperature of limbs (compare sides)
Lower limb:
- Dorsalis pedis, posterior tibial, popliteal, femoral pulse palpation
- Ankle-brachial index (ABI): normal ≥1.0; < 0.9 = PAD
- Buerger's test (for PAD)
- Venous examination: varicosities, Trendelenburg test
Carotid artery auscultation:
- Listen for bruits at angle of jaw using diaphragm
- Carotid bruits may radiate from AS or indicate carotid stenosis
- Method: ask patient to briefly hold breath; auscultate with patient turning head slightly away
3. GENERAL EXAMINATION - CVS SPECIFIC SIGNS MISSING
Hands (Missing entirely - very important for OSCE)
- Clubbing (detailed grading: Schamroth's sign, diamond sign)
- Peripheral cyanosis (nail beds)
- Splinter hemorrhages: infective endocarditis (IE)
- Osler's nodes: tender nodules on finger pads - IE

- Koilonychia (iron deficiency - AF, RHD)
- Tar staining (smoking → IHD)
- Tendon xanthomata (hypercholesterolemia → IHD)
Eyes:
- Corneal arcus (hypercholesterolemia, normal in elderly)
- Xanthelasma (hyperlipidemia)
- Argyll Robertson pupil (syphilitic AR)
- Conjunctival pallor (anemia → high output failure)
- Roth spots (IE)
Face:
- Malar flush / mitral facies (MS with low cardiac output)
- Central cyanosis (tongue, lips)
- High-arched palate (Marfan's syndrome → AR/MVP)
Neck:
- Carotid pulse character (best site for most pulse characters)
- Visible carotid pulsations in AR (Corrigan's sign in neck)
4. SIGNS OF INFECTIVE ENDOCARDITIS (High-Yield CBDC Topic)
This topic is completely absent from the PPT:
- Splinter hemorrhages - sub-ungual, linear, reddish-brown
- Osler's nodes - tender, erythematous nodules on finger/toe pads (immunological)
- Janeway lesions - non-tender, irregular hemorrhagic macules on palms/soles (embolic)
- Roth spots - oval retinal hemorrhages with pale center (fundoscopy)
- Clubbing in IE
- Duke criteria mention (major: blood cultures, echo findings; minor: fever, vascular/immunological phenomena)

6. COMPLETING THE EXAMINATION - OSCE MANDATORY CLOSING (Missing)
This is specifically marked in OSCE checklists and absent from the PPT:
- Thank and re-dress the patient
- Wash hands
- Summarize findings - practiced summary statement
- Request further investigations:
- ECG
- Chest X-ray
- Echocardiography
- Capillary blood glucose
- Urine dipstick
- Fundoscopy
- Peripheral vascular examination
- Pulse oximetry
7. OSCE STRUCTURED FORMAT (For CBDC Homoeopathy Pattern)
The OSCE/CBDC format requires the student to demonstrate a systematic 10-step approach. The PPT currently teaches content but lacks this structured "how to present it" framework:
Standard CVS OSCE Checklist (CBDC Pattern):
- Introduction - Wash hands, introduce self, obtain consent, adequate exposure, position at 45°
- General inspection from end of bed - comfortable/distressed, breathless at rest, cachectic, JVD visible, leg edema visible, O2/medications nearby
- Hands and arms - clubbing, cyanosis, capillary refill, tar staining, splinter hemorrhages, Osler's/Janeway, peripheral pulses (radial), radio-radial delay, blood pressure bilaterally
- Face and eyes - pallor (conjunctiva), central cyanosis (tongue), corneal arcus, xanthelasma, malar flush, dentition
- Neck - carotid pulse character and bruits; JVP height and waveform, abdominojugular reflux
- Precordial inspection - chest shape, scars (midline sternotomy = CABG/valve surgery; left lateral = mitral valvotomy; pacemaker scar), apex beat, visible pulsations
- Precordial palpation - apex beat (position + character), parasternal heave, thrills
- Percussion - cardiac borders
- Auscultation - all 4 areas, added sounds (S3/S4/OS/clicks), murmurs (timing, grade, radiation, maneuvers), carotid bruits, axilla, lung bases
- Completing - legs (pedal edema, saphenous harvest scars, PAD signs), sacral edema, thank patient, summarize, request investigations
8. SAMPLE OSCE SUMMARY STATEMENT (Slide to Add)
"I examined Mr. X, a 45-year-old male. On general inspection, he appeared comfortable at rest with no visible JVD. Peripheral stigmata of CVS disease were absent. Pulse was regular at 80/min, low volume with slow upstroke. BP was 130/80 mmHg in right arm. JVP was elevated at 5 cm with prominent a-wave. The apex was displaced to the 6th ICS anterior axillary line, with a sustained heaving quality. Parasternal heave was present. On auscultation, S1 and S2 were present; S2 was single. An ejection systolic murmur Grade III/VI was heard at the 2nd RICS radiating to both carotids. No diastolic murmur. Lung bases were clear. No pedal edema. These findings are consistent with aortic stenosis with LV hypertrophy. I would like to perform an ECG, chest X-ray, and echocardiogram to confirm."
Summary of Additions Recommended for the PPT
| Priority | Topic | Reason |
|---|
| HIGH | Auscultation - S1/S2 changes, S3, S4, splitting of S2 | Absent from PPT, most commonly asked |
| HIGH | Murmur recognition table (all 8 major lesions) | Core OSCE/CBDC content |
| HIGH | Hand examination - splinter hemorrhages, Osler's, Janeway | OSCE marks for IE peripheral signs |
| HIGH | OSCE structured checklist slide | Gives exam framework |
| HIGH | OSCE summary template/closing | Mandatory in OSCE |
| MEDIUM | Dynamic auscultation maneuvers | PG viva and OSCE |
| MEDIUM | AR peripheral signs (eponyms) | Frequently asked, high yield |
| MEDIUM | Kussmaul's/Pemberton's/Broadbent's signs | CBDC homoeopathy viva |
| MEDIUM | Peripheral vascular exam - ABI, Buerger's | Missing entirely |
| LOW | Eyes/face CVS signs | Add to general exam section |
| LOW | Duke criteria for IE | PG theory relevance |
The PPT is excellent and thorough for pulse, JVP, BP, and precordial examination through the percussion stage - these 58 slides are already a strong foundation. The main areas to add are the auscultation detail (biggest gap), hand signs, IE features, eponyms, dynamic maneuvers, and the OSCE structured closing protocol - all of which are specifically tested in both OSCE and CBDC pattern examinations for PG homoeopathy.
