Figures

None
Fig. 1 Aortic root angiography (left anterior oblique projection) reveals 4 aortic valve cusps, a small right coronary artery (single arrow), and aortic insufficiency jet (double arrows). Real-time motion images are available at texasheartinstitute.org/Holm314.html.
None
Fig. 2 Intraoperative transesophageal echocardiogram (short-axis view during diastole) of the quadricuspid aortic valve's “4-leaf clover” appearance. The left coronary artery is indicated by double arrows, and the small right coronary ostium, barely visible, is shown by a single black arrow. Two noncoronary cusps are symmetrically located on each side of the adjacent interatrial septum (single white arrow). Note the rectangular central regurgitant orifice. LA = left atrium, RA = right atrium, RVOT = right ventricular outflow tract Real-time motion images are available at texasheartinstitute.org/Holm314.html.
None
Fig. 3 Intraoperative transesophageal echocardiogram (long-axis view) of the quadricuspid aortic valve and ascending aorta (Ao) during diastole, with incomplete cusp closure. LA = left atrium Real-time motion images are available at texasheartinstitute.org/Holm314.html.
None
Fig. 4 Quadricuspid aortic valve cusps from the surgical aortotomy view. Note mild thickening of the cusps' edges and tips.
