摘要 目的:探讨经食管实时三维超声心动图(real-time three-dimensional transesophageal echocardiography,RT-3D-TEE)在二尖瓣脱垂解剖定位中的诊断价值。方法:对16例经胸超声心动图(transthoracic echocardiography,TTE)诊断为二尖瓣脱垂并重度关闭不全患者行RT-3D-TEE检查,观察二尖瓣脱垂解剖定位并作二尖瓣量化分析(quantitative of mitral valve,MVQ),与术中所见比对,观察TTE、RT-3D-TEE结果与手术所见的差异。结果:RT-3D-TEE可从外科视角清楚显示二尖瓣三维结构,在判断二尖瓣脱垂的解剖定位上比TTE具有更高的诊断价值,灵敏度、特异度分别为97.2%和100%,TTE对应灵敏度、特异度为50.0%和94.5%,两者灵敏度差异有统计学意义(P<0.001),但特异度差异无统计学意义(P=0.059)。结论:RT-3D-TEE可以清楚显示二尖瓣脱垂的三维结构变化,对二尖瓣脱垂定位相比于TTE更有临床意义。
