Left sinus of valsalva aneurysm in an adult with congenital unicuspid aortic valve

Abstract

Unicuspid aortic valve (UAV) is rare, but well-described congenital malformation in adults. Although aortic root and ascending aortic aneurysms can develop in unicommissural UAV, coexistence with left sinus of Valsalva aneurysm is an unusual event. Surgical correction is necessary to relieve left ventricular outflow tract obstruction associated with aortic stenosis in unicuspid aortic valve, and to decrease the substantial risk of impending rupture of sinus of Valsalva aneurysm.
