title: Coronary ostia obstruction after replacement of aortic valve prosthesis.
abstract: Aortic valve replacement (AVR) is the gold standard for the treatment of severe symptomatic aortic stenosis. Complications directly related to surgical procedure are relatively infrequent. Coronary ostial stenosis is, generally, referred as late complication. Anecdotal reports concern coronary ostial stenosis as acute complication. A unique fatal case of intraoperative, bilateral coronary ostial obstruction by prosthetic valve leading to an extensive myocardial infarction is reported. Surgeons must have a high level of vigilance regarding the occurrence of acute myocardial ischemia and sudden death soon after AVR.
