Fig. 2 Diagrammatic representations of the high-resolution digital transthoracic echocardiographic appearance of the aortic valves in both the open and closed state of Patients 1 and 2 (tricuspid aortic valves with partial commissural fusion) and of Patient 3 (bicuspid aortic valve) for comparison. These diagrams are composites of several individual frames in each state.

LC = left coronary cusp; NC = noncoronary cusp;

RC = right coronary cusp
