摘 要 目的 应用实时三维超声心动图(RT-3DE)技术评价左室心肌致密化不全(LVNC)患儿左室收缩功能及同步性。方法 选取34例LVNC患儿,按射血分数(EF)测值分为EF正常组(EF≥55%,25例)和EF减低组(EF<55%,9例),另选20例与其年龄、身高和体质量相匹配的健康儿童作为正常对照组。应用RT-3DE自动输出时间-容积曲线,获得收缩同步性参数16节段、12节段和6节段的Tmsv -SD、Tmsv-Dif与Tmsv -SD%、Tmsv-Dif%,比较两组上述参数的差异。结果 EF正常组与正常对照组比较,16节段与12节段的Tmsv -SD、Tmsv-Dif与Tmsv -SD%、Tmsv-Dif%,差异均有统计学意义(均P<0.05),而6节段差异无统计学意义;EF减低组与正常对照组比较,16节段、12节段和6节段的Tmsv -SD、Tmsv-Dif与Tmsv -SD%、Tmsv-Dif%,差异均有统计学意义(均P<0.05);EF正常组与EF减低组比较,16节段的Tmsv -SD、Tmsv-Dif与Tmsv -SD%、Tmsv-Dif%,差异有统计学意义(均P<0.05),余节段差异无统计学意义。结论 应用RT-3DE技术可对LVNC患儿左室收缩功能及收缩同步性进行早期评估,辅助儿科医师对制订更适合的治疗方案。 |

Abstract: |
ABSTRACT Objective To evaluate left ventricular systolic function and systolic synchrony in children with LVNC by RT-3DE.Materials and Methods 34 children with LVNC were enrolled .They were divided into EF normal group(EF≥55%,25 cases)and EF reduction group(EF<55%,9 cases).At the same time,20 healthy children who were consistent with the age,height and weight of the experimental group were selected as the normal control group. The RT-3DE automatically outputs the time - volume curve to obtain the systolic synchrony parameters 16 segments,12 segments and 6 segments(Tmsv -SD,Tmsv-Dif,Tmsv -SD%,Tmsv-Dif%).Results Compared with the normal control group, the EF normal group had Tmsv-SD、Tmsv-Dif and Tmsv-SD%、Tmsv-Dif% in 16 and 12 segments, and the differences were statistically significant(P<0.05),while 6 segments were no significant difference(P>0.05). The EF reduction group compared with the normal control group, Tmsv-SD、Tmsv-Dif and Tmsv-SD%、Tmsv-Dif% in 16 segments, 12 segments and 6 segments; the differences were statistically significant (P<0.05); The EF normal group compared with the EF reduction group,Tmsv-SD、Tmsv-Dif and Tmsv-SD%、Tmsv-Dif% in 16 segments were significant difference(P<0.05).Conclusion RT-3DE technique is used to evaluate the systolic function and systolic synchrony of LVNC in early stage,and assist pediatrician in selecting the appropriate treatment scheme to manage LVNC children. |
