Cardiac myxomas are the most common type of benign cardiac tumors and most of them occur in the left atrium but the biatrial myxoma is uncommon. We present a rare case of giant biatrial myxoma nearly obstructing the orifice of the inferior vena cava. A 58-year old woman presented with exertional dyspnea and intermittent chest discomfort. The non-pedunculated tumor involved most of the interatrial septum and extended from the orifice of the inferior vena cava to the displaced mitral annulus and the lower left pulmonary vein. The resected specimen weighed 76 gram and measured 80 × 40 × 30 mm. She did not complain of dyspnea or show any sign of recurrence by echocardiography during the 2-year follow-up period.
心脏黏液瘤是最常见的良性心脏肿瘤类型，大多数发生于左心房，但双房黏液瘤并不常见。我们报告一例罕见的巨大双房黏液瘤，几乎阻塞下腔静脉口。一名58岁女性因劳力性呼吸困难和间歇性胸部不适就诊。这个无蒂肿瘤累及大部分房间隔，从下腔静脉口延伸至移位的二尖瓣环和左下肺静脉。切除标本重76克，尺寸为80×40×30毫米。在2年随访期内，她没有诉说呼吸困难，超声心动图也未显示任何复发迹象。
