Structural Valve Deterioration

A 34-year-old woman was hospitalized with shortness of breath and chest tightness and pain. She had undergone aortic valve replacement for aortic stenosis at the age of 18 years. Transthoracic echocardiography showed left ventricular asynergy and a high aortic valve pressure gradient. Thus, structural valve deterioration was diagnosed. Coronary computed tomography and coronary angiography revealed left main trunk ostial stenosis that had caused acute anteroseptal myocardial infarction. Urgent surgery revealed pannus formation around the prosthetic valve and covering the ostium of the left main trunk. A Bentall procedure and coronary artery bypass grafting were performed. The postoperative course was uneventful.

Life Threatening

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 AV R 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.
