Validated calculators, step-by-step techniques, complete complication management, and the highlights from the major congresses — twice a week in your inbox.
Fast to check in the lab, complete enough to study at home.
What interventional cardiologists worldwide are debating on X, right now — curated.
The international interventional calendar — TCT, EuroPCR, ACC, ESC and more.
Gorlin, Qp/Qs, pulmonary resistance, continuity — with automatic interpretation.
Every chapter of Grossman & Baim and Brilakis, summarized for fast reference.
Original teaching plates — classifications, scores and waveforms, redrawn to share.
Tuesdays and Fridays: TCT, EuroPCR, and EuroIntervention summarized in your inbox.
The conversations, debates and papers moving the coronary world on X, right now — curated so you catch the signal, not the noise.
Note — In this prototype the Pulse is a curated snapshot of real themes trending in interventional cardiology. On the live site it syncs with X (official API / embedded timelines) and your own @intervhub feed, refreshing automatically.
The congresses and courses that move the field — where the late-breaking trials drop and techniques are taught. Ordered by typical time of year; exact dates change annually.
The concepts the classics illustrate — redrawn as clean, shareable diagrams. These are original illustrations made for this platform; we don't reproduce the books' copyrighted figures.
I — a crater outside the lumen, no extravasation. II — pericardial/myocardial blush without a jet. III — frank contrast jet through a hole > 1 mm. III cavity spilling — perforation draining into an anatomic chamber (e.g., coronary sinus). Severity rises left to right; class III demands the universal algorithm — balloon occlusion, then treat the cause.
Three binary digits — (proximal main, distal main, side branch) — each scored 1 if that segment has ≥ 50% stenosis, else 0. So (1,1,1) is a true bifurcation, (1,0,0) only the proximal main, (0,0,1) an isolated ostial side-branch lesion. The pattern frames whether a provisional single-stent or a planned two-stent strategy is likely.
One point each: a blunt / ambiguous proximal cap, calcification within the occlusion, a bend > 45°, an occlusion length ≥ 20 mm, and a previously failed attempt. Score 0 is easy, ≥ 3 very difficult — the anatomy that pushes you toward advanced dissection/re-entry or a retrograde approach. (Compute it live in Calculators → Scores.)
A crisp aortic tracing has a brisk upstroke and a dicrotic notch. A damped or ventricularized waveform means the catheter tip is against the wall, deep, or in an ostial lesion — injecting there risks dissection or hydraulic injury. The reflex: stop, disengage, restore a good waveform, then inject.
More plates coming — coronary angiographic projections, tamponade vs constriction tracings, calcium modification, TIMI/blush grades. All original artwork, safe to share.
Hemodynamic formulas and the scores you actually use in the lab — J-CTO, PROGRESS-CTO, RESOLVE, and the OCT/IVUS calcium scores. Enter the values and get the result and interpretation instantly.
Each course follows the real procedural workflow, with the decision points marked.
Guided puncture, valve crossing, positioning, and deployment.
Transseptal, LA navigation, leaflet capture, residual MR.
Antegrade, retrograde, dissection/re-entry, and complication management.
ASD/PFO closure, shunt calculation, and indication criteria.
