Bicuspid aortic valve in an adult human cadaver: a case report.
We encountered a "bicuspid" aortic valve in an 83-year-old man. This valve consisted of two semilunar leaflets, anterior and posterior, though they were extensively calcified. The right and left coronary arteries independently arose from the anterior aortic sinus. The infundibular ligament ran from the pulmonary trunk at the commissure of the right and left semilunar cusps to the aorta at the mid-point of the anterior sinus. These findings strongly suggests the present bicuspid aortic valve may be formed by fusion of usual right and left (coronary) cusps. No other congenital anomalies were noted in this heart.
