Isolated Coronary Ostial Stenosis

Isolated coronary ostial stenosis is a rare lesion and occurs predominantly in premenopausal females or in males who had been taking estrogens. This case report describes a male exhibiting an isolated left main coronary artery ostial stenosis and Leriche syndrome. This case was unique among 9702 cases in whom coronary angiograms had been performed between 1974 and December 1989 at the Yüksek İhtisas Hospital in Ankara, Turkey. This case illustrates that isolated ostial stenosis of the left main coronary artery can occur in a male not having taken estrogens.
