The article analyses the immediate and late-term results of mitral valve replacement by a MK4-25 ball prosthesis in 605 patients with mitral valvular disease. Operative lethality for the last 100 operations was 6%. The late-term results of valve replacement were studied in 381 patients in follow-up periods of 6 months to 17 years. 17-year survival was 69% among patients who underwent operation in functional class III and 48.8% among those operated on in class IV. The survival of patients and the late-term functional results depended on the duration of the disease and the degree of circulatory insufficiency before the operation. Timely implantation of a ball prosthesis corrects the hemodynamic disorders satisfactorily and improves the survival of patients.
本文分析了605例二尖瓣疾病患者使用MK4-25球瓣进行二尖瓣置换术的近期和远期结果。最近100例手术的手术死亡率为6%。对381例患者进行了随访，随访时间为6个月至17年，研究了瓣膜置换术的远期结果。功能分级为III级的手术患者17年生存率为69%，IV级手术患者的17年生存率为48.8%。患者的生存率和远期功能结果取决于疾病持续时间和术前循环功能不全的程度。及时植入球瓣可令人满意地纠正血流动力学紊乱并提高患者生存率。
