超声心动图在心脏占位性病变中的诊断价值

目的探讨心脏占位性病变的超声心动图表现及超声心动图对其诊断价值。方法对50例心脏占位性病变的超声心动图表现及临床资料进行回顾性分析，并与手术、病理或临床观察结果相比较分析。结果本组心脏占位性病变以黏液瘤、血栓、赘生物最常见。黏液瘤及血栓主要发生于左心房，超声易于检出。黏液瘤多为低回声，有蒂连于心内壁，活动度大；血栓多为较强回声，一般无蒂，活动度低；赘生物主要发生在二尖瓣和主动脉瓣，多有感染性心内膜炎病史，易影响到瓣膜功能，引起相应的超声表现，超声可监测其治疗效果及转归。结论超声心动图是目前检出和评价心脏占位性病变的首选工具，常规超声心动图检查能准确描述病变的部位、大小、数量、形状、活动性及其与周邻组织结构的关系，多普勒超声心动图能评价占位性病变所致的血流动力学改变。

Diagnostic value of echocardiography in space-occuping heart lesions

Objective To evaluate the performance of the cardiac space-occupying lesions and their diagnostic values by using echocardiography. Methods The echocardiography performance and clinical data in the fifty cases with cardiac lesions were analyzed with a retrospective method. Results Myxoma,thrombosis and neoplasm were most common lesions in all cases of cardiac lesions. The myxoma and thrombus were mainly observed in the left atrium and easily detected by ultrasound. The myxoma,with flexible movement,mostly s...
