Calcified Sinus of Valsalva Aneurysm Eroding into the Interventricular Septum

Abstract

A 12-year-old male patient with complete heart block was diagnosed by cardiac catheterization to have an unruptured aneurysm of the sinus of Valsalva eroding into the interventricular septum. Aortic regurgitation was absent and he underwent permanent pacemaker implantation. Three years later, he was readmitted with severe aortic regurgitation and left ventricular failure. The pacemaker was replaced and the patient underwent successful patch closure of the aneurysm and aortic valve replacement. The mode of presentation, noninvasive methods of evaluation, and surgical management of this rare cardiac pathology are discussed.
