实时三维超声心动图诊断先天性三尖瓣畸形的价值

摘要

Objective To evaluate the value of real-time three-dimensional echocardiography(RT-3DE)in diagnosing congenital tricuspid valve anomaly.Methods Eighteen patients with congenital tricuspid valve anomaly were studied by RT-3DE,the spatial framework and neighboring structures of the tricuspid valve were analyzed and compared with result of the operation.Results The anomaly of tricuspid,chorda tendineae,the papillary muscle and their connection with neighboring structures could be displayed clearly from different directions.The diagnose accordance rate of RT-3DE was 83%.Conclusions RT-3DE may provide more information on congenital tricuspid valve anomaly than 2DE.%目的 探讨实时三维超声心动图(RT-3DE)在诊断先天性三尖瓣畸形中的应用价值.方法 观察18例三尖瓣病变患者的三维图像,了解三尖瓣病变部位的空间结构及毗邻关系,并与手术结果相对照.结果 RT-3DE可从不同方向观察三尖瓣病变的瓣叶、瓣下腱索及乳头肌的形态、位置及其周围的空间结构,与手术结果比较诊断符合率83%.结论 RT-3DE观察三尖瓣畸形可补充二维超声心动图的不足,为临床提供丰富的信息.
