Report of the case of a 12 years old boy, who because of acquired mitral valve insufficiency (grades II--III), after an illness of virus-carditis, became, in the first instance, a Bjoerk-Shiley-Ventil M27 prosthetic valvular replacement, and after 3 months, in one sitting, correction of a paravalvular leakage and prosthetic valvular replacement of the insufficient aortic valve with a Bjoerk-Shiley A23. The boy was well rehabilitated one year after the last operation. This is supported by the similar results of the echocardiographic, the ergometric and the pulmonary function tests carried out. The size of the replaced prosthetic valve makes the long time prognosis favourable. Double-valvular prosthetic replacement in children was hitherto carried out predominantly as a result of rheumatic diseases. The rheumatic process as well as congenital valvular malformation could surely be excluded in our patient so that the virus-process seems to be the most likely cause of the valvular defect.
一名12岁男孩的病例报告。该男孩因病毒性心肌炎患病后出现获得性二尖瓣关闭不全（II - III级），最初接受了Bjoerk - Shiley - Ventil M27人工瓣膜置换术，3个月后一次性进行了瓣周漏修补以及用Bjoerk - Shiley A23人工瓣膜置换功能不全的主动脉瓣。在最后一次手术后一年，该男孩康复良好。超声心动图、测力计和肺功能测试的类似结果也证实了这一点。所置换人工瓣膜的尺寸使长期预后良好。迄今为止，儿童双瓣膜人工置换主要是由于风湿性疾病进行的。在我们的患者中，可以肯定地排除风湿过程以及先天性瓣膜畸形，因此病毒感染过程似乎是瓣膜缺陷最可能的原因。
