What's Inside — 5 A4 Portrait Slides

Slide	Topic	Image Included
1	Title Slide — Navy/teal design with topic overview	—
2	Left Ventricular Non-Compaction (LVNC) — embryology, epidemiology, Jenni echo criteria, genetics (TAZ/Barth, MYH7), management	Echo: NC/C ratio >2:1, spongy LV
3	Arrhythmogenic RV Cardiomyopathy (ARVC) — PKP2/DSP genetics, 2010 Task Force criteria, athlete SCD risk, RFA/ICD	Cardiac MRI: RV dilation + fibro-fatty infiltration
4	Restrictive Cardiomyopathy (RCM) — idiopathic vs storage diseases, biatrial dilation, RCM vs constrictive pericarditis table, transplant indication	CMR: severe biatrial dilation, normal ventricles
5	Takotsubo + Arrhythmia-Induced CM — apical ballooning, catecholamine surge, PVC burden thresholds, PJRT in infants, RFA outcomes	Echo: apical ballooning + base hyperkinesis

Design: Navy/teal academic palette, A4 portrait (8.27×11.69 in), section tags, key-fact boxes, clinical pearls, footer, and slide numbers. All images are real clinical/research diagnostic images from the medical literature.

Early Signs Bacterial Endocarditis

Presentation · PPTX

Design — Completely Different from the Previous Deck

Feature	Previous (Cardiomyopathy)	This (Endocarditis)
Palette	Navy + teal + white	Crimson + warm cream + gold
Background	Dark navy	Warm vellum/cream
Typography	Calibri throughout	Georgia for headings + Calibri for body
Layout	Left text + right image	Numbered card system (title) + side-panel with header sidebar
Slide numbers	Teal circle badge	Rust sidebar tab with "0X of 5"
Accent style	Flat color bands	Gold rules + pale-red tint cards + dark info boxes

Slide-by-Slide Content

#	Topic	Clinical Image
1	Title — numbered card overview	—
2	Osler Nodes & Janeway Lesions — painful vs painless, immune vs embolic, minor Duke criteria	Clinical photo: Janeway lesions (sole) + Osler nodes (digit) — dual panel
3	Splinter Hemorrhages & Clubbing — nail exam technique, Schamroth test, conjunctival petechiae	Subungual splinter hemorrhages in multiple nails
4	Roth Spots & Ocular Signs — fundoscopy, fibrin-platelet centre, differential of white-centred haemorrhage	Fundus: Roth spot with white-arrow annotation
5	Cardiac Signs + Modified Duke Criteria — new murmur, AV block/abscess, early red-flag patterns	TEE: vegetation on posterior mitral leaflet

PDF Document · PDF

Why This PDF Has Perfect Alignment

Unlike PowerPoint (which uses floating text boxes that can drift), this was built with ReportLab canvas — every element is placed at exact pixel coordinates:

Text wrapping is handled word-by-word with measured string widths — no overflow or clipping
Column grids are mathematically defined (left margin, column gap, right margin)
Image aspect ratios are preserved and centred inside their bounding boxes
Section headers, body text, and captions each have their own precisely defined Y-positions
Gold underrules and colour bands align flush to their companion text elements

What's on Each Page

Page	Content
1	Title with intro paragraph + 4 numbered topic cards
2	Osler Nodes vs Janeway Lesions — image left, two sub-sections right, comparison table full-width
3	Splinter Haemorrhages & Clubbing — image right, content left, examination checklist box
4	Roth Spots — fundus image left, mechanism + differential right, fundoscopy guide box
5	Cardiac signs + TEE image + full Modified Duke Criteria table + red-flag box

What's New in This Version

Images — 13 total, multiple per page

Page	Images
1	2 neonatal/infant TTE echos (vegetation on mitral valve, paediatric cardiac exam with Doppler) + topic cards
2	3 cutaneous sign photos: Osler nodes + Janeway dual panel · Janeway on foot/ankle · Janeway on paediatric digit
3	2 nail/peripheral photos: splinter haemorrhages (multiple nails, blue circles) · Osler node + splinter on same finger
4	2 Roth spot fundus photos: single Roth spot with white arrow · Multiple Roth spots + preretinal haemorrhage
5	3 cardiac/pathology images: TEE vegetation on mitral · Gross aortic valve with vegetation + perforation · Surgical multi-valve IE specimen

Text Density — 20+ lines per page

Every page has fully word-wrapped content in 2 columns with 7–8 heading + body pairs each — roughly 25–30 rendered text lines per page. A dedicated clinical note on neonatal IE appears on pages 1, 2, 3, 4, and 5.

Layout Fix

All paragraphs use measured word-wrapping (ReportLab stringWidth) — no text overflows, no misaligned columns, no drifting boxes.

Now do the same for first topic align every line perfectly i want everything in bullet points 20 lines in each page

Alignment Guarantee

Every • bullet symbol is drawn at exactly BX = ML + 4mm and every text line starts at exactly TX = ML + 9mm — no drift, no offset, identical on every single line across all 5 pages.
