Isolated Sternal Cleft in a Patient With Coronary Artery Disease.

Abstract

A cleft sternum is a very rare developmental anomaly. It is caused by failure of fusion of the two lateral mesodermal sternal bars which later form the sternum. Diagnosis of cleft sternum is generally made in the neonatal period, and it is usually associated with other congenital defects. Occasionally, patients with cleft sternum may be reported late in the childhood or even in adulthood. We present the case of an adult patient with sternal cleft diagnosed incidentally in the perioperative period at the time of off-pump coronary artery bypass grafting. No other skeletal or cardiac congenital anomalies had been noted previously in this patient.
