Occlusion of left coronary artery ostium by an aortic valve cusp.

Congenital anomalies of the aortic valve can be associated with other cardiac anomalies. In this report, we present a patient with an aortic valve anomaly associated with occlusion of left coronary ostia. In addition, we reviewed the literature and found 10 similar cases. Although compatible with life, this anomaly can lead to significant symptoms. Preoperative diagnosis as well as proper therapeutic planning should be tailored to correct valvular competence and restore coronary blood flow.
