| 摘 要： | 目的探讨无支架生物瓣的置入技术及其早期临床效果.方法对12例平均年龄65岁的主动脉瓣病变病人,选用St.Jude公司提供的TorontoSPV瓣膜,行主动脉瓣置换术.结果全组手术死亡1例,平均主动脉阻断时间(95.0±12.3)?min,其中单纯主动脉瓣置换者为(74.0±9.2)?min.术后1个月随访超声心动图显示均无主动脉瓣反流,跨瓣压差明显较其他人工瓣膜小,左心室舒张末期内径明显缩小,无栓塞、出血等并发症.结论尽管无支架生物瓣膜置入有一定难度,但其优良的血液动力学性能,提示其能提高病人的远期疗效.

| Abstract: | Objective: To study the implantation skill of aortic valve replacement with stentless porcine valve (SPV) and the early clinical results. Methods: Between Nov.1999 and Jun. 2000, the Toronto SPV valve was implanted in 12 patients (mean age 65 years). All patients were followed up at one month postoperation with doppler echocardiography.Results: There was one operative death. Echocardiography indicated that the blood flow across a Toronto SPV bioprothesis resembles that of a normal aortic valve. Conclusion: Toronto SPV valves provide excellent clinical results. It may enhance regression of left ventricular hypertrophy and restoration of normal ventricular function. |
