A 35-year-old man presented with 9 years of chronic chest pain and was found to have moderate-to-severe aortic regurgitation on echocardiography. Aortic valve morphology on the initial echocardiogram was deemed normal. Computed tomography angiography was obtained for further evaluation of the aortic root dimension and anatomy. In addition to noninvasive evaluation of the coronary arteries, the higher spatial resolution and volumetric coverage of computed tomography angiography can better define the valvular and aortic anatomy. Reconstruction of retrospectively gated cine images through the aortic valve plane revealed a quadricuspid valve with 4 equal-sized cusps. Incomplete coaptation of the aortic valve cusps was seen during diastole, explaining the marked aortic regurgitation. In addition, a dilated ascending thoracic aorta (4.7 cm) was revealed. On the basis of these findings, the patient was treated surgically with a composite valve graft replacement of his aortic root. |
