Long axis image of the left ventricular outflow tract showing cross-section images ranging from valve cusp to annulus ring. (a-f) Quadricuspid aortic valve images ranging from valve cusp to annulus ring in diastole showing mild non-coaptation of valve cusps that corresponds with mild aortic regurgitation. Two equal large and small valves are seen. All four valves are functional. (b) Mixed density plaque is noted at the proximal left main stem coronary artery (black arrow).

A quadricuspid aortic valve with two large and smaller cusps (Hurwitz and Roberts anatomical classification type C) was also demonstrated along with mildly impaired coaptation of the valve cusps (Figures 1 and 2).
