Assessment of systolic synchrony and longitudinal movement of left ventricle in hypertrophic cardiomyopathy using tissue tracking

摘要

摘要: 目的探讨应用组织追踪法(TT)评价肥厚型心肌病(HCM)患者左室收缩协调性和纵向运动功能.方法利用TT技术获取22例HCM患者和20例正常对照者的左室壁运动曲线,分别测量心尖长轴、心尖二腔和心尖四腔切面的二尖瓣环、基底段中部、中段乳头肌水平的收缩期峰值位移(Ds)、相对室壁达峰时间差(△Dt)和峰值位移差(△Ds).结果与对照组比较,HCM组△Dt明显延长,△Ds明显增大,Ds明显降低,差异有显著性意义.结论 HCM患者存在左室收缩协调障碍和纵向运动功能损害,TT能定量评价HCM患者左室收缩协调性和纵向运动功能.
