The results obtained in 20 patients with the use of continue suture technic for prosthetic implantation of the mitral valve were compared to those observed in other 20 patients in which the prothesis were implanted with isolated suture technic. With the first one the aortic clamp time was reduced in average about 50 minutes; the extracorporeal circulation time also diminished in the same proportion. One patient died in each group, meaning a 5% of hospital mortality. The going after time in the first group was 2.5 years and in none was found prosthetic dysfunction or perivalvular lickage. We conclude that prosthetic implantation technic for mitral valve with continue suture, offers the following advantages: a) Important reduction of the transoperative myocardial ischemia. b) Reduction also, of the hole estracorporeal circulation time. c) Minor possibilities of periprosthetic lickage. d) Minor risk of valvular thrombosis in the suture line.
将20例使用连续缝合技术进行二尖瓣人工瓣膜植入术的患者的结果与另外20例使用间断缝合技术植入人工瓣膜的患者的结果进行了比较。采用第一种技术时,主动脉阻断时间平均缩短约50分钟;体外循环时间也以相同比例减少。每组各有1例患者死亡,即医院死亡率为5%。第一组的随访时间为2.5年,未发现人工瓣膜功能障碍或瓣周漏。我们得出结论,二尖瓣人工瓣膜连续缝合植入技术具有以下优点:a)显著减少术中心肌缺血。b)也减少体外循环时间。c)瓣周漏的可能性较小。d)缝合线处瓣膜血栓形成的风险较小。
