A rare cause of systolic murmur: unruptured right sinus of Valsalva aneurysm with right ventricular outflow tract obstruction and supracristal ventricular septal defect.

ABSTRACT

Dyspnea and heart murmur are common reasons for referrals in cardiology and both are associated with a broad differential diagnosis. Sinus of Valsalva aneurysms are rare abnormalities of the aortic root that should be considered in the differential diagnosis in young and middle aged patients. Sinus of Valsalva aneurysms are often associated with supracristal ventricular septal defects and can be identified on transthoracic echocardiography. Diagnosis of a SVA should trigger a careful search for ventricular septal defect, which may necessitate transesophageal echocardiography.
