The incidence and management of coronary ostial stenosis.

Abstract

Coronary ostial stenosis in the absence of more peripheral coronary artery disease was present in four patients (0.093%) of 4298 angiograms performed on patients with coronary artery disease. Case reports of four patients undergoing coronary artery bypass graft surgery for isolated coronary ostial stenosis are presented and surgical techniques discussed. Three patients were young females (mean age 31 years). It is suggested that coronary ostial stenosis is a rare variant of coronary artery disease, more common in young women.
