Sinus of Valsalva aneurysm (SVA) is a rare congenital heart malformation of one or more of the aortic sinuses, consisting of a dilation that when unruptured is usually asymptomatic but when ruptured presents with progressive exertional dyspnea, fatigue, chest pain and that can lead to congestive heart failure if left untreated.

A sinus of Valsalva aneurysm (SOVA) is a rare cardiac condition that includes an abnormal dilatation of the aortic root between the aortic valve annulus and the sinotubular junction caused by weakness in the elastic lamina at the junction of the aortic media and the annulus fibrosis.
