摘要 目的探讨实时三维经食管超声心动图(RT3DTEE)与经食管二维超声心动图(2DTEE)诊断二尖瓣脱垂的临床价值。方法选取2017年1月—2019年7月在笔者所在医院行二尖瓣修补成形术治疗的原发性二尖瓣脱垂患者50例,术前均行RT3DTEE与2DTEE检查。以术中直视所见为金标准,分析RT3DTEE与2DTEE诊断二尖瓣脱垂效能,以及两种诊断方法检查结果与术中直视所见的一致性,并分析RT3DTEE与2DTEE检查所用时间差异。结果 50例患者术中直视所见A1 43例、A2 37例、A3 32例;P1 38例、P2 31例、P3 11例;腱索断裂13例;RT3DTEE诊断二尖瓣脱垂的阴性预测值、敏感度、准确度、特异度、阳性预测值为85.99%、89.27%、90.86%、93.10%、94.82%,高于2DTEE,差异具有统计学意义(P<0.05);kappa检验显示:RT3DTEE与术中直视所见的一致性良好(kappa值=0.814,P<0.05);2DTEE与术中直视所见的一致性不佳(kappa值=0.253,P<0.05);RT3DTEE检查时间为(4.81±1.16) min,短于2DTEE检查的(18.10±5.14) min,差异有统计学意义(P<0.05)。结论与2DTEE相比,RT3DTEE诊断原发性二尖瓣脱垂具有高敏感度、高准确度、高特异度的特点,且能够缩短检查时间。
