Carpentier's ring was inserted in the mitral annulus of 79 patients suffering from mitral valve disease. 49 other patients also underwent surgery on other cardiac valves and are not considered in the present study. The mean follow up time was 19.5 months. The total hospital and late mortality in the isolated ring series was 3.8%. Clinical and hemodynamic improvement was evident postoperatively. The preoperative functional class (NYHA) of the patients was: I, 11.39%; II, 45.5%; III, 34.1%; IV, 8.86% respectively. The postoperative class was: I, 86.8%; II, 7.9%; III, 3.9%; and IV, 1.3% respectively. Postoperative hemodynamic and angiocardiographic evaluation was done in 27 patients. Mean pulmonary artery pressure fell from 49.8 +/- 2.4 mm. Hg to 38 +/- 2 mm. Hg. Mitral regurgitation present preoperatively in 66.6% of cases was present in residual form in only 18.5%. Atrial enlargement was moderate in 42.1% and severe in 57.9% before operation, and 80.3 moderate and 19.7 severe after operation. Tromboembolic accidents occurred in 2 patients (2.2%) both with severe atrial enlargement and atrial fibrillation pre and postoperatively. We conclude that Carpentier's ring is a valid alternative in the surgery of mitral valve disease.
卡彭蒂埃环被植入79例二尖瓣疾病患者的二尖瓣环。另外49例患者还接受了其他心脏瓣膜手术，本研究未纳入这些患者。平均随访时间为19.5个月。单纯环植入组的总住院死亡率和晚期死亡率为3.8%。术后临床和血流动力学改善明显。患者术前的心功能分级（纽约心脏协会）分别为：I级，11.39%；II级，45.5%；III级，34.1%；IV级，8.86%。术后分级分别为：I级，86.8%；II级，7.9%；III级，3.9%；IV级，1.3%。对27例患者进行了术后血流动力学和心血管造影评估。平均肺动脉压从49.8±2.4毫米汞柱降至38±2毫米汞柱。术前66.6%的病例存在二尖瓣反流，术后仅18.5%以残余形式存在。术前42.1%为中度心房扩大，57.9%为重度心房扩大，术后80.3%为中度，19.7%为重度。2例患者（2.2%）发生血栓栓塞事件，术前和术后均有严重心房扩大和心房颤动。我们得出结论，卡彭蒂埃环是二尖瓣疾病手术中的一种有效替代方法。
