title: Left Main Coronary Ostial Stenosis after Aortic Valve Replacement: A Case Report.
abstract: Coronary ostial stenosis is a rare but potentially life-threatening complication of aortic valve replacement (AVR). It can present potential complications such as acute coronary syndrome, left ventricular failure, ventricular arrhythmias, or sudden death. Exact pathogenetic mechanism is not known, but a few hypotheses have been proposed. We present a case of left main coronary stenosis 11 months after AVR was done for symptomatic critical aortic stenosis. High index of clinical suspicion and timely coronary angiography helped to determine the exact etiology. A percutaneous coronary intervention was done emergently. The patient has done very well so far.
