Blood Supply of the Cardiac Conduction System — Summary
■ SA node:
▪︎ 60% from Right Coronary Artery.
▪︎ 40% from Left Circumflex Artery.
■ AV node:
▪︎ ~85–90% from Right Coronary Artery.
▪︎ ~10–15% from Left Circumflex Artery.
■ Bundle of His:
▪︎ Proximal: Right Coronary Artery.
▪︎ Distal: Septal branches of Left Anterior Descending Artery.
■ Right bundle branch:
▪︎ Septal branches of Left Anterior Descending Artery.
■ Left bundle branch:
▪︎ Septal branches of Left Anterior Descending Artery.
✅ Key pearl:
● RCA infarction → sinus node dysfunction & AV block.
● LAD infarction → bundle branch blocks.

I hope it never happens to me: percutaneous en bloc extraction of a rotablator burr stalled within a stent, with stent and guidewire! https://t.co/xpPZGgJQ8K @ccijournal
Heart catheterization shows us only a glimpse of the coronary circulation. Most of the tiny vessels that nourish the heart remain invisible, yet they’re vital for its survival.
In a week full of exciting IVI guided PCIs and peripheral interventions, this case took the 🎂!
51 y/o woman sent home from the ER with non cardiac CP after a normal workup. Readmitted a week later with DOE.
This is her angio. What to do now? FFR/CFR, IVUS, OCT, NIRS, or PET?
