Left atrial myxomas are extremely difficult to diagnose since their variable manifestations mimic a host of clinical entities more commonly seen, e.g. mitral stenosis, endocarditis, rheumatic fever, cardiomyopathy or mesenchymosis. At the same time, early diagnosis followed by prompt surgical removal are mandatory to prevent mutilating or lethal complications of the tumor. Six cases of left atrial myxoma were diagnosed in our hospital during 2 1/2 years. We present the case histories, diagnostic procedures and surgical findings, consolidating the unique role of echocardiography in detecting left atrial myxomas. We propose the use of echocardiography as a screening examination for atrial myxomas in the following settings: suspected mitral obstructive disease, suspected endocarditis with negative blood cultures, peripheral embolism or thrombosis in young patients, unexplained cardiac failure and mesenchymosis with uncharacteristic presentation.
左心房黏液瘤极难诊断，因为其表现多样，可模仿许多更常见的临床病症，如二尖瓣狭窄、心内膜炎、风湿热、心肌病或间质性病变。与此同时，早期诊断并及时手术切除对于预防肿瘤致残或致命并发症至关重要。在两年半的时间里，我院诊断出6例左心房黏液瘤。我们展示病例病史、诊断程序及手术结果，强化超声心动图在检测左心房黏液瘤方面的独特作用。我们建议在以下情况下将超声心动图用作心房黏液瘤的筛查检查：疑似二尖瓣阻塞性疾病、血培养阴性的疑似心内膜炎、年轻患者的外周栓塞或血栓形成、不明原因的心力衰竭以及表现不典型的间质性病变。
