The bicuspid aortic valve--an autopsy study

Congenital Bicuspid Aortic Valve is a common congenital anomaly. We studied 48 cases of bicuspid aortic valve seen over a period of 20 years. 18 cases were associated with other congenital anomalies, patent ductus arteriosus being the most frequent. 30 were isolated lesions. The morphology of the cusps and position of raphe were noted. Calcification and infective endocarditis were frequently noted in the isolated forms of Bicuspid Aortic Valve. Coronary arteries were dissected in 32 cases to determine the dominance.
