Abstract:
Objective To explore the left ventricular systolic function in patients with atrial fibrillation(AF) and heart failure with normal ejection fraction (HFnEF) using tri‐plane 2D ,3D speckle tracking imaging (STI ) and single‐beat real‐time three‐dimensional ultrasound .Methods Thirty‐four patients with AF and HFnEF were enrolled as HFnEF group and twenty‐nine AF patients without any kind of heart failure as control group .Left ventricular ejection fraction (LVEF ) was measured by bi‐plane Simpson′s method ,regional systolic function of left ventricle was evaluated by 2D‐STI and 3D‐STI ,and synchronism of left ventricle was assessed using tissue Doppler imaging (TDI) ,tri‐plane 2D‐STI and 3D‐STI .Results HFnEF group had higher two‐dimensional longitudinal strain and lower two‐dimensional radial strain .Left ventricular synchronism in HFnEF group was significantly poorer than that in control group . Conclusions 2D/3D STI is more sensitive than TDI and it can discover contractility abnormal and asynchronism in patients with both AF and HFnEF with the help of tri‐plane imaging and single‐beat real‐time three‐dimensional ultrasound .
