CTICasesType A aortic dissection with valve prolapse
Imaging findings
Chest CT and echocardiography demonstrate a Stanford Type A aortic dissection with an intimal flap in the ascending aorta that prolapses retrograde through the aortic valve plane into the left ventricular outflow tract during diastole.
Key takeaways
Retrograde prolapse of an aortic dissection flap through the aortic valve is a rare but classic mechanism of acute, severe aortic insufficiency. It can be visualized on CT and echocardiography as a mobile intimal flap crossing the valve plane.
