As percutaneous mitral valvuloplasty gains wider acceptance, appropriate selection of patients for this procedure continues to be important. The presence of atrial thrombus is a contraindication, and transesophageal echocardiography provides optimal visualization of the left atrium and atrial appendage to assess for the presence of thrombus. This case report describes a patient in whom left atrial thrombus was suspected based on standard precordial echocardiography. After transesophageal echocardiography demonstrated the structure in question to be a normal portion of the left atrial wall, the patient underwent successful uncomplicated percutaneous mitral valvuloplasty. We recommend transesophageal echocardiography in all patients being considered for percutaneous valvuloplasty for mitral stenosis.
随着经皮二尖瓣成形术得到更广泛的认可，为该手术恰当选择患者仍然很重要。心房血栓的存在是一种禁忌证，而经食管超声心动图能够最佳地显示左心房和心耳，以评估血栓的存在情况。本病例报告描述了一名患者，基于标准的心前区超声心动图怀疑其存在左心房血栓。经食管超声心动图显示该可疑结构是左心房壁的正常部分后，该患者成功接受了无并发症的经皮二尖瓣成形术。我们建议，所有考虑行经皮二尖瓣狭窄成形术的患者均应接受经食管超声心动图检查。
