摘要:
目的 用二维斑点追踪技术测定三尖瓣环位移对漏斗胸术前、术后患儿与正常对照组的对照研究, 探讨在临床上应用该技术评估漏斗胸患儿右心室收缩功能变化的运用价值.方法 选取明医科大学附属儿童医院2017年2月至8月心脏外科进行治疗的漏斗胸患儿38例作为漏斗胸组, 同时另选50例年龄相匹配的健康儿童作为对照组.分别测量三尖瓣环室间隔收缩期峰值位移 (TMAD1) 、三尖瓣环右心室游离壁收缩期峰值位移 (TMAD2) 、三尖瓣环连线中点收缩期峰值位移 (TMADm) 以及右心室纵向缩短分数 (TMAD%) .结果 漏斗胸患儿组的TMAD1、TMAD2、TMADm以及TMAD%值均小于正常对照组儿童 (P<0.05) .漏斗胸患儿经手术后, 其TMAD1、TMAD2、TMADm以及TMAD%值, 术后均较术前有所增加, 但无统计学差异 (P>0.05) .结论 斑点追踪测定三尖瓣环位移可以准确、简洁的评价漏斗胸患儿右心室收缩功能情况, .但对于手术后的数据改善情况评价, 有待进一步研究探讨.
Abstract:
Objectives To explore the value of tricuspid annulus displacement measured by speckle tracking on evaluating the right ventricular systolic function in children with pectus excavatum (PE) . Me thods Pectus excavatum patients group (PE group) recruited 38 patients with pectus excavatum and treated with cardiac surgery from February to August in 2017 and 50 healthy children with matchedage were randomly enrolled as control group.Tricuspid ring ventricular septal systolic peak displacement (TMAD1) , tricuspid ring right ventricular free wall (TMAD2) systolic peak displacement, tricuspid ring attachment midpoint displacement (TMADm) and right ventricular systolic peak longitudinal shortening fraction (TMAD%) were measured. Re s ults The value of TMAD1, TMAD2, TMADm and TMAD% in PE group was lower than those in control group (P<0.05) . After the patients in PE group underwent surgeries, the value of TMAD1, TMAD2, TMADm and TMAD % increased but there was no significant difference (P>0.05) . Conclus ions Speckle tracking can accurately and clearly evaluate right ventricle systolic function in the children with pectus excavatum, but further study is needed to explore the value of the post-operative data.
