Intracavitary tumors of the atria are rare, generally diagnosed as myxoma, and considered benign. Of 20 such tumors presenting for surgery between Jan 1, 1967, and Jan 1, 1982, sixteen were myxomas: 13 in the left and three in the right atrium. Four additional patients operated on for suspected right atrial myxoma had other lesions: two thrombus (simulating myxoma), one leiomyoma originating in the right iliac vein, and one clear cell adenocarcinoma from the left kidney. One initially benign myxoma underwent malignant transformation. Eighteen hospital survivors were followed up from one month to 134 months (mean, 61 months). All are New York Heart Association class I. We recommend inferior vena cavagram for right-sided lesions. For patients older than 40 years, coronary angiography and appropriate bypass grafting should be performed. Surgery must include resection of all abnormal tissue. Follow-up with echocardiography should continue for five years.
心房腔内肿瘤较为罕见，通常诊断为黏液瘤，被认为是良性的。在1967年1月1日至1982年1月1日期间接受手术的20例此类肿瘤中，16例为黏液瘤：13例位于左心房，3例位于右心房。另外4例因疑似右心房黏液瘤接受手术的患者有其他病变：2例血栓（类似黏液瘤），1例起源于右髂静脉的平滑肌瘤，以及1例来自左肾的透明细胞腺癌。1例最初为良性的黏液瘤发生了恶性转化。18名住院幸存者接受了1个月至134个月（平均61个月）的随访。所有患者均为纽约心脏协会心功能I级。对于右侧病变，我们建议进行下腔静脉造影。对于40岁以上的患者，应进行冠状动脉造影和适当的搭桥手术。手术必须包括切除所有异常组织。应继续进行五年的超声心动图随访。
