Figure 3 Aortic leaflet prolapse is best visualized in a long-axis view of the aortic valve, aortic root and ascending aorta, which is usually obtained at approximately 120° by multiplane TEE. The top panel shows a long-axis view of the aortic valve and aortic root. The long narrow gray arrows point to an intimal dissection flap that extends into the aortic root. The broad white arrow points to right coronary cusp that is prolapsing into the left ventricular outflow tract behind the noncoronary cusp, seen above. The bottom panel shows an eccentric jet of severe AR that is directed posteriorly into the left ventricular outflow tract. AO = aorta; LA = left atrium; LVOT = left ventricular outflow tract.
