Two cases of prosthetic valve dysfunction resulting in acute massive mitral regurgitation are reported; emergency operation was successful in both cases. Survival following complete dislodgement of the occluder of a disc valve, as occurred in one case, does not appear to have been reported before. The diffculty in diagnosis of sudden cardiac decompensation in patients with prosthetic valves is stressed, as is the need for urgent operation.
报告了两例人工瓣膜功能障碍导致急性大量二尖瓣反流的病例；两例均成功进行了急诊手术。其中一例发生的盘状瓣膜封堵器完全脱位后的存活情况，此前似乎未见报道。强调了人工瓣膜患者突发心脏失代偿的诊断困难，以及紧急手术的必要性。
