摘要
目的 进一步探讨双孔成形技术治疗二尖瓣前叶脱垂的临床可行性。方法 对 35例二尖瓣前叶脱垂的病人行双孔成形手术 ,并在术前、术中、术后利用超声心动图对瓣膜进行评价。并与同期行二尖瓣置换者进行比较。结果 全组术前平均瓣口面积 ( 8 3± 1 6 )cm2 ,术后瓣口面积为 ( 4 1±1 8)cm2 。术后 33例病人无瓣膜反流 ,2例二尖瓣轻度反流。全组无术后死亡。随访 1~ 40个月 ,所有病人心功能 (NYHA)为I级 ;超声心动图显示双孔成形瓣膜活动良好 ,无瓣口狭窄。结论 双孔瓣膜成形技术治疗二尖瓣前叶脱垂 ,疗效稳定 ,死亡率低 ,无并发症 ,早期、中期疗效满意。
Objective: To evaluate the clinical effect of the double-orifice technique in the treatment of the anterior leaflet prolapse of mitral valve. Methods: 35 patients with severe anterior leaflet prolapse of mitral valve underwent valve repair using the double-orifice technique. The condition of valve was assessed with echocardiography preoperatively, intraoperatively, and postoperatively. Results: The mean postoperative valve area was (4 1±1 8) cm 2 against the preoperative valve area of (8 3±1 6)cm 2. Mild regurgitation was found in 2 patients after operation. There were no hospital deaths. At the latest follow-up, the heart function was improved significantly in all patients (NYHA class I). Echo-Doppler assessment of valve showed stable valve function in all patients. There were no late stenosis of valve and no late death. Conclusion: The results of this study show that the double-orifice technique is a safe and effective method for treatment of anterior leaflet of mitral valve with low mortality and morbidity, and excellent early and mid-term results.
