摘要
目的探讨经食管实时三维超声心动图(RT3D-TEE)诊断二尖瓣脱垂的价值。方法 20例二尖瓣脱垂患者于术前1周内行RT3D-TEE检查,判断瓣膜病变的类型、部位、病因,并与手术结果对照。结果 20例患者中18例RT3D-TEE检查发现的二尖瓣瓣膜及腱索的病变与术中探查相符,准确率为90%。瓣膜脱垂部位诊断符合率为90%,其中对于单发病变部位的准确性为100%。结论 RT3D-TEE能实时动态显示瓣膜病变类型、部位、程度,为手术方式、方案的设计提供重要信息。
Objective To evaluate the value of real-time three-dimensional transesophageal echocardiography （RT3D-TEE） in diagnosing mitral valve prolapse. Methods Twenty cases of mitral valvular prolaps were examined by RT3D- TEE within 1 week before operation, the type, position and etiological factor of valvular prolaps were judged, the results were compared with surgery. Results The pathological changes of mitral valva and chordae tendineae examined by RT3D-TEE were accordant with those of surgery in 18 cases with the accuracy rate of 90%. The accordance rate for diagnosis of lesion location was 90%, the accuracy rate for judgement of solitary lesion location was 100%. Concbtsion RT3D-TEE can dynamically display the pathological type, position and extent of mitral valve prolapse, and so can provide reliable information for planning of surgical procedure.
