Diastolic pressure gradient in the ascending aorta caused by the mobile intimal flap of dissecting aneurysm

Abstract

Aortic regurgitation is a serious complication of ascending aortic dissection. We report a 65-year-old man with Type A aortic dissection and aortic regurgitation who presented with a diastolic aortic pressure gradient along the aortic root which was caused by a large intimal flap interrupting the diastolic regurgitant flow.
