Myxoma is the most common type of benign cardiac tumor in adults. Myxoma can occur anywhere in the heart. The left atrium is the most frequent site of origin, specifically located on the left atrium side of the fossa oval in the atrial septum, followed by the right atrium, the right ventricle and left ventricle. But biatrial myxoma is extremely rare. Thoracoscopic resection of myxoma has become more common, but there are few reports on thoracoscopic surgery for biatrial myxoma. We present a case of a 72-year-old woman with biatrial myxoma, who presented with intermittent dyspnea for one week. Echocardiography revealed a medium echo in both the left and right atrium and was connected via the atrial septum. Computed tomography revealed a hypointense mass in both atria. Thoracoscopic resection successfully removed the tumors, and histological examination confirmed the diagnosis. Also, the patient was discharged six days after surgery. There was no evidence of tumor recurrence during the one-year follow-up period. Biatrial myxoma is rare. Surgical resection is the primary method for myxoma. Compared with the traditional medium thoracotomy, thoracoscopic surgery for myxoma has the following advantages: less trauma, keeping the integrity of the sternum, less bleeding, faster postoperative recovery, etc. Total thoracoscopic surgery for biatrial myxomas is effective and safe.
黏液瘤是成人最常见的良性心脏肿瘤类型。黏液瘤可发生于心脏的任何部位。左心房是最常见的起源部位，具体位于房间隔卵圆窝的左心房侧，其次是右心房、右心室和左心室。但双房黏液瘤极为罕见。胸腔镜下切除黏液瘤已较为常见，但关于双房黏液瘤胸腔镜手术的报道较少。我们报告一例72岁患有双房黏液瘤的女性病例，该患者因间歇性呼吸困难1周就诊。超声心动图显示左、右心房均有中等回声，且通过房间隔相连。计算机断层扫描显示双房有低强化肿块。胸腔镜切除成功切除了肿瘤，组织学检查确诊。此外，患者术后6天出院。在1年的随访期内无肿瘤复发迹象。双房黏液瘤较为罕见。手术切除是黏液瘤的主要治疗方法。与传统的正中开胸手术相比，黏液瘤的胸腔镜手术具有以下优点：创伤小、胸骨完整性得以保留、出血少、术后恢复快等。双房黏液瘤的全胸腔镜手术有效且安全。
