Abstract

The authors report a case of dysfunction of a double hemi-disc mitral valve prosthesis due to peri-annular fibrous overgrowth on the atrial side of the prosthesis. Conventional transthoracic Doppler echocardiography showed signs of thrombosis of the prosthesis. Transoesophageal echocardiography allowed a precise diagnosis of the lesions, resulting in immediate surgical referral.

摘要

作者报告了一例双半盘式二尖瓣人工瓣膜功能障碍的病例，原因是人工瓣膜心房侧的瓣环周围纤维组织过度生长。传统经胸多普勒超声心动图显示人工瓣膜有血栓形成迹象。经食管超声心动图能够精确诊断病变，从而立即转诊进行手术。
