三尖瓣下移畸形的超声诊断与鉴别诊断

Echocardiography in Diagnosis and Differential Diagnosis of Ebstein Anomaly

目的 总结超声心动图准确诊断及鉴别诊断三尖瓣下移畸形、三尖瓣缺如及三尖瓣发育不全的问题并提出改进意见。方法 对７０ 例先天性三尖瓣畸形手术患者的超声诊断结果与手术结果对照进行回顾性分析。结果 ６６ 例三尖瓣下移畸形超声均做出定性诊断，下移瓣叶及合并畸形的诊断灵敏度不一。２ 例三尖瓣发育不全超声误诊为三尖瓣下移畸形，２ 例三尖瓣缺如的超声诊断经手术结果证实。

Objective To evaluate echocardiography in diagnosis and differential diagnosis of Ebstein anomaly,absence of tricuspid valve and dysphasia of tricuspid valve. Methods Retrospective analyzed data of echocardiography and surgery in 70 patients with tricuspid anomaly. Results Qualitative diagnosis of 66 Ebstein's anomalies were truly made with echocardiography.There were different sensitivities in displacement of valves and complications.2 dysphasia of tricuspid valve were faultily considered as Ebstein's anomaly.2 absences of tricuspid valves were proved by surgery. Conclusion Echocardiography can be used in diagnosis and differential diagnosis of congenital tricuspid anomaly. [
