对 51例心脏原发性肿瘤进行回顾性分析 ,其中 4 2例为左房粘液瘤 (82 .4 % ) ,6例为右房粘液瘤(11.9% ) ,1例为左室横纹肌瘤 (1.96 % ) ,2例为右室纤维肉瘤 (3.92 % ) ,全部病例均做心脏超声检查 ,符合率10 0 % ,被认为是确诊本病的首选及最佳方法。本文同时对心房粘液瘤瘤蒂长短、活动度大小、基底部宽窄与手术时间及方法选择的关系 ,各种肿瘤最佳切面观察进行了讨论。 A retrospective analysis was performed on 51 cases of primary cardiac tumors, including 42 cases of left atrial myxoma (82.4%), 6 cases of right atrial myxoma (11.9%), and 1 case of left ventricular leiomyoma (1.96). %), 2 cases of right ventricular fibrosarcoma (3.92%), all cases were performed echocardiography, the rate of 10%, is considered to be the first choice and the best method for the diagnosis of this disease. At the same time, the relationship between the pedicle length, the size of the activity, the width of the basement, and the operation time and method selection were discussed.
