简介：左心室（LV）舒张功能降低可对右心室（RV）施加显著负荷，从而影响RV肺血管（PV）耦合。RVPV可通过RV长度-力关系（三尖瓣环平面收缩期偏移[TAPSE]与肺动脉加速时间[PAAT]比值）进行评估。我们的目的是确定使用组织多普勒成像（TDI）和TAPSE/PAAT测量的LV舒张功能之间的相关性。
Introduction: Reduced left ventricular (LV) diastolic function can exert significant load to the right ventricle (RV) that can affect RVpulmonary vasculature (PV) coupling. RVPV can be assessed with the RV lengthforce relationship (tricuspid annular plane systolic excursion [TAPSE] to pulmonary artery acceleration time [PAAT] ratio). We aimed to determine the association between LV diastolic function measured using tissue Doppler imaging (TDI) and TAPSE/PAAT.Methods: A study of premature infants
