JACC:分流术类型对于Fortan治疗前有单右心室异常患儿的心脏大小和功能的影响

2014-12-01 MedSci译 MedSci原创

背景:在患有单右心室(RV)异常改变的儿童中,右心室的大小和功能可能受Norwood程序中选择的分流类型的影响。 目的:研究试图确定在Norwood治疗幸存者中接受14个月和小于等于6个月的前房坦治疗患者的超声心动图的区别。 方法:我们对比了两组病人2维多普勒超声心动的右心房大小和功能的指数,新主动脉环和三尖瓣环的尺寸和功能,主动脉尺寸,以及 14.1±1.2个月和33.6±9.6个月

背景:在患有单右心室(RV)异常改变的儿童中,右心室的大小和功能可能受Norwood程序中选择的分流类型的影响。


目的:研究试图确定在Norwood治疗幸存者中接受14个月和小于等于6个月的前房坦治疗患者的超声心动图的区别。

方法:我们对比了两组病人2维多普勒超声心动的右心房大小和功能的指数,新主动脉环和三尖瓣环的尺寸和功能,主动脉尺寸,以及 14.1±1.2个月和33.6±9.6个月的血管通畅程度。这两组接受诺伍德程序治疗的患者,分别被随机分配到Blalock-Taussig分流术(MBTS)和右心室-肺动脉分流术(RVPAS)。

结果:在两个时间段有240名患者可以做超声心动图(114 MBTS ,126 RVPAS)。 在14个月时,两组所有的指数都相似。从 14个月到前房坦治疗的超声心动图,MBTS组有稳定的右心室体积分数指数RV和心脏射血分数,而rvpas组右心室体积增加(P = 0.004),右心室射血分数减少(P = 0.004)。从14个月到前房坦治疗,两组的主动脉瓣区指数,轻度主动脉瓣回流(<5 % 每次)指数,三尖瓣指数和轻度三尖瓣回流(<20% 每次),均相似。




结论:在单右心室异常患病者换把第二年和第三年,右心室射血分数恶化后,初始诺伍德治疗的分流术类型影响预房坦的右心室重塑。可喜的是,不论哪种分流类型,右心室其他指标保持稳定,在房坦之前。(对比两种分流对单心室缺陷患儿进行分阶段重建的影响--小儿心脏网;nct00115934)
