Percutaneous Treatment of Left Main Coronary Artery Ostial Stenosis After Bentall Operation

Iatrogenic coronary ostial stenosis (ICOS) is a rare but life-threatening complication of aortic root surgery. It can occur with the incidence of 0.3%-5% and affect more commonly the left main coronary artery (LMCA) compared to the right coronary artery (RCA). Here, we present a case of non-ST-elevation myocardial infarction that occurred after a Bentall aortic root replacement, due to compression of the left main ostium, which was effectively treated with percutaneous coronary intervention.
