. , , 608-612. . One hundred patients with mixed mitral valve disease have been treated with the stand-by' bypass principle. In 59 the valve was replaced; in 41 a closed transventricular valvotomy was done. The results in the two groups have been compared. The operative mortality for valvotomy was 7%; for valve replacement 20%. Late death occurred in 14% after valvotomy; in 25% after replacement. Good' results were achieved in 49% after valvotomy; in 41% after replacement. Among the survivors 61% had `good' results after valvotomy as against 75% after replacement. Late emboli occurred in one patient after valvotomy; in 11 after replacement. Methods for improved selection of patients for simple valvotomy are discussed.
100例二尖瓣混合性病变患者采用“备用”体外循环原则进行了治疗。其中59例行瓣膜置换术;41例行经心室闭式瓣膜切开术。对两组结果进行了比较。瓣膜切开术的手术死亡率为7%;瓣膜置换术为20%。瓣膜切开术后晚期死亡率为14%;置换术后为25%。瓣膜切开术后49%取得“良好”效果;置换术后为41%。存活者中,瓣膜切开术后61%取得“良好”效果,而置换术后为75%。瓣膜切开术后1例发生晚期栓塞;置换术后11例发生。文中讨论了改进单纯瓣膜切开术患者选择的方法。
