摘要

目的:探讨组织多普勒成像评价慢性心衰患儿左心室纵轴收缩功能的价值。方法:应用组织多普勒成像测量22例正常儿童和25例慢性心衰患儿左室各节段长轴方向各取样点收缩期的峰值速度（Vs）及峰值位移（Ds）。结果:①慢性心衰患儿的Vs、Ds显著减低。②治疗后心内膜弹力纤维增生症（Endocardial fibroelastosis

EFE）患儿各节段的Vs、Ds显著改善。③瓣环的平均Vs和Ds与左室射血分数（Left ventricular ejection fraction

LVEF）相关性最好。结论:组织多普勒成像可定量评价慢性心衰患儿的左心纵轴收缩功能

可更加全面、敏感的评价收缩功能。

Abstract

Objective:To assess the left ventricular(LV)systolic function of long-axis direction in patients with chronic heart failure using quantitative tissue Doppler imaging.Methods:22 healthy subjects and 25 patients with chronic heart failure were studied by QTVI and TTI

peak velocities of LV regional myocardium during systole(Vs)

and peak systolic displacements(Ds)were measured.Results:①Vs and Ds of LV segments in patients with chronic heart failure were significantly lower than those in healthy subjects.②after 6 months treatment

Vs and Ds of LV segments in patients with endocardial fibroelastosis were significantly recovery.③mean Vs and Ds at the mitral annulus level correlated significantly with LVEF.Conclusion:QTVI and TTI can assess LV systolic function of long-axis direction in patients with chronic heart failure

can more entirely and sensitive assess the systolic function
