The data of long-term follow-up of 67 patients subjected to mitral valve replacement for severe heart diseases support the rationale of surgical management of chronic circulatory insufficiency in mitral disease. A prosthetic replacement of the mitral valve helps to return the majority of operated on patients to active live patterns. Improvements of the patients' state within 5 years after surgery was recorded in 58 cases, 9 patients died within 2 to 34 months. Actuarial statistics showed that the 5-year survival rate comprised 75.9% following prosthetic mitral valve replacement.
对67例因严重心脏病接受二尖瓣置换术患者的长期随访数据支持二尖瓣疾病慢性循环功能不全外科治疗的基本原理。二尖瓣人工瓣膜置换术有助于使大多数接受手术的患者恢复积极的生活模式。58例患者术后5年内病情改善，9例患者在2至34个月内死亡。精算统计显示，二尖瓣人工瓣膜置换术后5年生存率为75.9%。
