The discussion covers long-term results of mitral valve replacement with Soviet-made prostheses. Two hundred and sixty-three patients have been under observation, the follow-up periods lasting from six months to five years. A ball-valve prosthesis (MK4-25) was implanted to 125 patients; 138 patients received a low-profile (,) prosthesis. Functional parameters were improved in 86 (69.9 percent) patients with ball-valve implants and in 118 (89 percent) patients with low-profile implants. Ten ball valve implanted patients (8 percent) and 6 (4.3 percent) patients with low-profile prostheses died in the long-term period. The five-year survival of rotation-disc artificial valve recipients was 90 percent, and that of the ball valve-implanted patients, 83 percent.
讨论内容包括使用苏联制造的假体进行二尖瓣置换的长期结果。263名患者接受了观察，随访期从6个月到5年不等。125名患者植入了球瓣假体（MK4 - 25）；138名患者接受了低轮廓假体。植入球瓣的86名患者（69.9%）和植入低轮廓假体的118名患者（89%）的功能参数得到改善。长期来看，10名植入球瓣的患者（8%）和6名植入低轮廓假体的患者（4.3%）死亡。旋转盘式人工瓣膜接受者的五年生存率为90%，植入球瓣的患者为83%。
