Aortic regurgitation due to back-and-forth intimal flap movement detected by both multidetector computed tomography and transesophageal echocardiography.

ABSTRACT: A 46-year-old man with a history of hypertension, chronic kidney disease, and chronic aortic dissection classified as DeBakey type IIIB was referred to our hospital with chest and back pain. The patient underwent 64-row multidetector computed tomography (MDCT), which revealed new-onset DeBakey type II aortic dissection. The intimal flap prolapsed into left ventricle in the diastolic phase of cardiac cycle and stuck to the right coronary cusp (RCC) of the aortic valve. He also underwent transesophageal echocardiography (TEE) to assess the relationship between the intimal flap and aortic valve in detail. The intimal flap overlaid the RCC and prolapsed into the left ventricle outflow tract in the diastolic phase. These images suggested that the circumferential intimal flap stuck to the aortic
