A patient with rheumatic mitral stenosis and previous cerebral embolism had a myocardial infarction during cardiac catheterisation. She later developed severe mitral regurgitation one year after open valvotomy and at valve replacement was found to have a papillary tumour of the mitral valve. Unexplained low cardiac output occurred four days after operation. Postmortem examination showed thrombotic occlusion of the xenograft prosthesis, a complication not previously seen with tissue valves. Both of these rare events were suggested by the patient's clinical course and could have been diagnosed with cross sectional echocardiography.
一名患有风湿性二尖瓣狭窄并曾有脑栓塞病史的患者在心脏导管插入术期间发生心肌梗死。她在二尖瓣直视切开术后一年出现严重二尖瓣反流，在瓣膜置换时发现有二尖瓣乳头状瘤。术后四天出现不明原因的低心输出量。尸检显示异种移植人工瓣膜血栓形成阻塞，这是组织瓣膜以前未见的并发症。这两个罕见事件均由患者的临床病程提示，通过横断面超声心动图本可作出诊断。
