Submitral aneurysms are rare clinical entities occurring predominantly in young adults of African descent. A host of etiologies have been proposed for this entity. We present a unique case of submitral aneurysm which developed after pulmonary artery banding in a three-year-old girl with complex congenital heart disease. The aneurysmal sac was burrowing into the interatrial septum.
