摘　　要：目的探寻右心房黏液瘤的超声特点,评价超声心动图对右心房黏液瘤的诊断价值。方法回顾分析20例右心房黏液瘤的超声表现,总结右心房黏液瘤的超声心动图特点。结果右心房黏液瘤的临床症状主要有胸闷、气短、下肢浮肿及晕厥等。超声测量瘤体大小为3.11 cm×2.90 cm^7.44 cm×4.52 cm,形态为类圆形或分叶状。瘤蒂附着于房间隔者占75%,附着于右心房游离壁者占25%。瘤蒂平均宽度为(1.62±0.30)cm,宽度大于1 cm者占80%。部分黏液瘤内部可见钙化和囊状无回声区。右心房内血流阻塞占70%,三尖瓣狭窄占50%,肺高压者占10%。结论超声心动图可以准确评价右心房黏液瘤瘤体特点及继发心内结构和血流动力学改变,为临床作出及时、准确诊断提供重要依据。Objective To investigate the echocardiographic features in patients with right atrial myxoma and thus evaluate the value of echocardiography in the diagnosis of right atrial myxoma. Methods The echocardiographic findings of 20 patients with right atrial myxomas were retrospectively analyzed,and the echocardiographic features of these patients were summarized. Results The main clinical symptoms of right atrial myxoma included chest tightness,shortness of breath,lower limb edema,and syncope. Of these 20 patients,the echocardiography showed that the average size of the right atrial myxomas was 3.11 cm×2.90 cm to 7.44 cm×4.52 cm. The myxomas were round or oval shape in 15 patients（75%）and lobulated shape in 5（25%）. The myxomas were attached to the atrial septum in 15 patients（75%）and to right atrial free wall in 25% of the patients. The average width of the basement was 1.62±0.30 cm,and the width was greater than 1 cm in 80% of the patients had the width over 1 cm. Some myxomas had internal areas of calcification and anechoic cystic areas. The percentages of patients with the blocking of right atrium,tricuspid and pulmonary hypertension were 70%,50%,and 10%,respectively. Conclusion The echocardiographic features of right atrial myxoma were specific. Echocardiography can accurately assess the tumor and identify the secondary changes in cardiac structure and hemodynamics and thus provide evidence for timely and accurate diagnosis of right atrial myxoma.
