Isolated unruptured sinus of Valsalva aneurysm producing right ventricular outflow obstruction

Abstract
An unusual case of right ventricular outflow obstruction and right heart failure due to an isolated unruptured congenital sinus of Valsalva aneurysm originating from the right coronary sinus in a 75‐year‐old‐man is described. The diagnosis was made by twodimensional echocardiography and cardiac catheterization. Successful surgical resection of the aneurysm resulted in dramatic symptomatic improvement.
