The aortic valve is normally tricuspid or trileaflet. When two of the cusps are fused together, the valve becomes functionally “bicuspid.” Most commonly, the right and left coronary cusps are ...

Long-axis parasternal view, revealing the intensity of calcification and doming of the aortic cusps in systole. Left ventricular outflow tract (LVOT) diameter may be measured for valve area ...
