A case of unruptured right sinus of Valsalva with intraventricular septal dissection and complete heart block

Unruptured right sinus of Valsalva causing intraventricular septal dissection and presenting as complete heart block is an extremely rare entity. We report a 38 years old male patient presenting with an episode of syncope. Electrocardiogram revealed complete heart block. Echocardiography and aortic root angiogram showed an aneurysm from right sinus of Valsalva dissecting the intraventricular septum. Patient refused operation and only permanent pacemaker implantation was done for complete heart block.
