We describe acute dysfunction of a bileaflet mechanical mitral valve prosthesis for the first time in a 57-year-old male. Unlike two-dimensional transesophageal echocardiography, three-dimensional imaging convincingly showed a large rounded echo density consistent with a papillary muscle in contact with one of the leaflets showing only partial opening during systole.
我们首次描述了一名57岁男性双叶机械二尖瓣假体的急性功能障碍。与二维经食管超声心动图不同，三维成像令人信服地显示出一个大的圆形回声密度，与一个乳头肌与其中一个瓣叶接触一致，该瓣叶在收缩期仅部分打开。
