摘要

A sinus of Valsalva aneurysm (SOVA) is abnormal dilatation of the either aortic sinuses, area of the aortic root between the aortic valve annulus and the sinotubular junction. Their clinical presentation may range from being asymptomatic as an incidental finding on cardiac imaging to symptomatic presentations related to the compression of adjoining structures or intracardiac shunting caused by rupture of the SOVA mostly into the right side of the heart. The compression leads to findings of tricuspid valve regurgitation, right ventricular outflow tract (RVOT) obstruction and rarely complete heart block (CHB). Dissection or erosion into interventricular septum is one of the rarest complications of SOVA. The symptomatic presentation is almost always a surgical emergency. Here we present a case report of a patient with unruptured sinus of valsalva originating from right sinus dissecting into interventricular septum causing complete heart bock. In this case after surgical correction the complete heart block reverted to sinus rhythm.
