Giant pulmonary artery aneurysm with right ventricular outflow tract obstruction.

Aneurysm of the main pulmonary artery is rare. Its natural history is not well understood and there are no clear guidelines regarding its optimal treatment. We present a case of a huge saccular aneurysm of the main pulmonary artery which was associated with infundibular and valvular pulmonary stenosis. It was repaired using a pericardial patch with concomitant pulmonary valvotomy and infundibular resection. Postoperative recovery was uneventful and the patient is doing well. Follow-up echocardiogram revealed good repair.
