Ruptured Sinus of Valsalva Aneurysm Initially Misdiagnosed as Ventricular Septal Defect by Echocardiography

Abstract: Aneurysms of sinus of valsalva are rare cardiac lesions and most of them are in congenital prigin. The malformation consists of a separation or lack of fusion between the media of the aorta and the annulus fibrosis of the aortic valve. The structure becomes aneurysmal and may rupture to form a fistula. We present a case of ruptured sinus of valasalva aneurysm in a 25-year-old man. The diagnosis was made by echocardiography and confirmed at operation.
