title: Successful surgical repair of pulmonary artery aneurysm and regurgitation.
abstract: Pulmonary artery aneurysm (PAA) is generally a rare lesion, and there is no definitive approach for it. We report the case of a 45-year-old man who was admitted for the evaluation of dyspnea. In childhood, he had been diagnosed with PAA with congenital pulmonary valve stenosis and regurgitation, and he had a percutaneous transvenous pulmonary valve commissurotomy. Transthoracic echocardiogram showed dilatation of the right atrium and right ventricle, with right ventricular hypertrophy. There was severe pulmonary valve regurgitation, and the main pulmonary artery was dilated to 68 mm in diameter. From the surgical findings, the left leaflet of pulmonary valve was torn from commissure with failure to coapt with the other leaflet. After direct sutures of edges of the left leaflet, a nearly normal valvular competence was restored. The PAA was repaired with a Y-shaped 24 × 12 mm Dacron graft replacement. The postoperative course was uneventful, and the patient was discharged.
