Where is the perforation and where is the blood extravasating?

mid LAD perforation and extravasation in pericardium

mid LAD perforation and extravasation in the right ventricle

mid LAD perforation and extravasation in coronary sinus

Correct! The correct answer is "mid LAD perforation and extravasation in coronary sinus".

In a routine PTCA, LAD artery was dilated with 2.5x15 mm semi-compliant balloon. Angiogram immediately after it showed Ellis’s grade III perforation. However, there was no pericardial effusion or any immediate hemodynamic compromise.

Good try! The correct answer is "mid LAD perforation and extravasation in coronary sinus".
