Transaortic coronary patchplasty for isolated main left coronary ostial stenosis: a report of five cases

The incidence of isolated ostial stenosis of the left main coronary artery varies between 0.13% and 2.7%. We performed surgical ostial angioplasty in five patients who had isolated left coronary ostial stenosis. One patient had low systemic blood pressure and, after the procedure, manifested myocardial ischaemia: conventional aortocoronary bypass was performed. The outcome of the four others was uneventful. They remained free of symptoms and resumed normal activities. Transaortic patch angioplasty might be useful operative method for the isolated coronary ostial stenosis, since it restores a more physiologic perfusion of the coronary arteries.
