    Abstract:
    The development of left main coronary artery stenosis is a rare complication arising after aortic valve replacement. We report the different clinical course of two cases. One patient developed typical exertional angina 3 months after uneventful aortica valve replacement. Coronary stenosis had been excluded on preoperative coronary angiography. One day before hospital admission for coronary angiography the patient died suddenly. The second patient reported symptoms typical of angina 6 months after aortic valve replacement. Coronary angiography revealed critical left coronary ostial stenosis, which was successfully treated by surgical revascularization. These cases demonstrate the rare, yet potentially fatal complication of left coronary ostial stenosis. Early coronary angiography seems warranted in the event of typical exertional angina, even after angiographic exclusion of relevant coronary artery stenosis before aortic valve replacement.
