Successful Surgical Correction of Partial Atrioventricular Septal Defect in an Elderly Patient：Report of a Case

はじめに　われわれは79歳で手術を行った不完全型房室中隔欠損症（partial atrioventricular septal defect：pAVSD）を経験した．手術は左側房室弁形成，心房中隔一次孔欠損パッチ閉鎖術，三尖弁輪形成術を施行した．70歳以上の高齢者での手術報告はまれであり，術後4年の経過においても良好な状態が保たれているので報告する．

There are only few reports on surgery for partial atrioventricular septal defect （pAVSD） in patients aged over 70 years. This report is about successful surgical correction of pAVSD in a 79-year-old women. Echocardiography showed left-sided atrioventricular valve regurgitation with cleft and ostium primum atrial septal defect, but without ventricular septal defect. Accordingly, she was diagnosed with pAVSD. Treatment plan included direct cleft closure, patch closure for the ostium primum atrial septal defect, and right atrioventricular annuloplasty. The postoperative course was uneventful. She was followed up without complications for four years. To the best of our knowledge, our patient is the oldest to undergo such surgical techniques in Japan to date.
