Impairment of the left ventricular ejection induced by a mitral prosthesis remains an infrequent complication, perhaps because it often is unrecognized. This complication would mainly be seen with ball prostheses or standard bioprosthesis used in mitral valve replacements with a small ventricle. Two cases have been recently reported during mitral valve replacement. The two patients were successfully re-operated upon, one after five weeks and the second immediately after the first procedure. A review of the literature enable to specify the etiology and diagnostic criteria with the assistance of Doppler-sonocardiography. Early re-operation may prevent death, often due to a post-operative myocardial dysfunction.
二尖瓣人工瓣膜导致的左心室射血功能损害仍然是一种罕见的并发症，可能是因为它常常未被识别。这种并发症主要见于用于小心室二尖瓣置换术的球笼型人工瓣膜或标准生物瓣膜。最近在二尖瓣置换术中报告了两例。两名患者均成功接受了再次手术，一例在五周后，另一例在首次手术后立即进行。文献回顾有助于在多普勒超声心动图的辅助下明确病因和诊断标准。早期再次手术可能预防死亡，死亡通常是由于术后心肌功能障碍。
