Abstract

A 68-year-old man underwent double-valve replacement (DVR) for active infective endocarditis caused by Enterococcus faecalis. Postoperative coronary angiography (CAG) revealed a saccular aneurysm originating from the distal portion of LMCA with severe stenosis at the ostium of the left anterior descending (LAD) artery and left circumflex artery (LCx). Emergent surgical resection with concomitant coronary artery bypass grafting were performed.
Mycotic coronary artery aneurysms have a great tendency to rupture, and this may result in cardiac tamponade and sudden death. Early recognition and prompt surgical intervention is mandatory to minimize those fatal complications.
