1	WUnicuspid Aortic Valve- An Uncommon Anomaly With a Common Presentation Sitwala, Puja, Abusara, Ashraf, Ladia, Vatsal, Ladia, Vatsal, Panchal, Hemang B., Raudat, Charles, Paul, Timir K. 01 March 2016 (has links) Unicuspid aortic valve (UAV), which is a rare congenital anomaly, usually presents as aortic stenosis and/or aortic regurgitation. Here we present a case of UAV co-existent with an ascending aortic aneurysm. A 26-year-old male with no significant past medical history presented to the hospital after two episodes of syncope. Transthoracic echocardiogram showed an ejection fraction of 62%, severely stenotic aortic valve, and moderate aortic regurgitation. Computed tomography revealed calcification of the aortic valve, compatible with aortic stenosis and aneurysm of the ascending aorta measuring 4.3 cm in diameter. He underwent successful aortic valve replacement and repair of ascending aortic aneurysm. He recovered well without any complications. This case suggests that any young patient who presents with syncope, aortic stenosis would be a differential and further workup by any available non-invasive modality needs to be performed. adult aortic aneurysm (complications diagnostic imaging) aortic valve (abnormalities diagnostic imaging surgery) aortic valve stenosis (etiology) diagnosis differential echocardiography doppler echocardiography transesophageal humans male syncope (etiology)
