[Successful repair of isolated extracardiac unruptured sinus of Valsalva aneurysm; report of a case].

: We report a case of isolated, unruptured extracardiac aneurysm of the right coronary sinus of Valsalva. The aneurysm was detected incidentally in a 75-years-old woman during the treatment of angina pectoris. A 30×35 mm sized aneurysm was located in the right sinus of Valsalva with extracardiac protrusion. It was repaired by obliterating its orifice with an autologous pericardial patch reinforced by a polytetrafluoroethylene (PTFE) patch. Early surgical repair should be a treatment of choice for this entity to prevent catastrophic event.
