Abstract

Right atrial aneurysm is an extremity rare congenital heart defect. We report a case which was diagnosed during the early fetal stage and operated on in a 2 week old neonate. Following median sternotomy, aneurysmectomy was performed under a cardiopulmonary bypass. Histopathological examination of the resected atiral tissue showed a lipotomatous degeneration and reduction of the muscular elements. There were no postoperative complications.
