【摘要】：目的采用斑点追踪成像(STI)评估房间隔缺损(ASD)患儿左心室扭转运动特征,探讨ASD患儿右心室容量负荷与左心室扭转运动的关系,以期指导临床应用。资料与方法收集2015年10月-2016年1月于上海儿童医学中心行心脏超声检查确诊为ASD患儿58例(病例组),并根据右心室容量分为右心室容量明显增加组(ASD-A组,30例)及右心室容量增加不明显组(ASD-B组,28例)。同时收集年龄、性别匹配的30例正常儿童为对照组。应用STI测量并比较各组左心室扭转运动参数。结果 ASD-A组中6例患儿基底部与心尖部均呈逆时针旋转。与对照组相比,ASD-A组左心室基底部旋转角度、心尖部旋转角度均明显增大,差异有统计学意义(P0.01);左心室扭转角度峰值及扭力大于对照组,差异有统计学意义(P0.05)。与对照组相比,ASD-B组仅心尖部旋转角度显著性增大(P0.05),其余左心室扭转运动参数呈增大趋势,但差异均无统计学意义(P0.05)。结论 ASD导致右心容量负荷明显增加时对左室基底部旋转运动及心尖部旋转运动具有较大影响。
[Abstract]:Objective to evaluate the characteristics of left ventricular torsion in children with atrial septal defect (ASD) by speckle tracking imaging (STI), and to explore the relationship between right ventricular volume load and left ventricular torsion in children with ASD.Materials and methods 58 children with ASD diagnosed by echocardiography from October 2015 to January 2016 at Shanghai Children's Medical Center (case group) were divided into two groups according to right ventricular volume: 30 cases in ASD-A group and 30 cases in ASD-A group with significantly increased right ventricular volume; andThe right ventricular volume was not increased significantly in ASD-B group (n = 28).At the same time, 30 normal children with age and sex matching were collected as control group.Left ventricular torsion parameters were measured and compared by STI.Results in ASD-A group, the basal base and apex of 6 children were rotated counterclockwise.Compared with the control group, the left ventricular basal rotation angle and the apex rotation angle in ASD-A group were significantly increased, the difference was statistically significant (P 0.01), and the left ventricular torsion angle peak value and torsion force were higher than those in the control group (P 0.05).Compared with the control group, the apical rotation angle increased significantly in ASD-B group, while the other left ventricular torsion motion parameters showed an increasing trend, but there was no significant difference between them.Conclusion the right ventricular volume load induced by ASD has a great effect on the left ventricular basal rotation and apical rotation.
