Abstract:
Objective To evaluate left ventricular (LV) systolic function in patients with paroxysmal atrial fibrillation (PAF) after catheter ablation by three-dimensional speckle tracking imaging (3 D-STI). Methods A total of 35 patients with PAF who underwent catheter ablation were enrolled in this study. The participants underwent standard echocardiography and 3 D-STI three to six months before and after the operation. 30 healthy volunteers were enrolled as controls. 3 D-STI was used to obtain global longitudinal strain (GLS) , global circumferential strain (GCS) , global radial strain (GRS) , and global area strain (GAS). Results The LA and E/e' ratio in PAF group showed no significant difference before and after the operation, but were increased compared with controls.There were no significant differences between PAF group and control group in LV, left ventricular end-diastolic volume (LVEDV) , left ventricular end-systolic volume (LVESV) and left ventricular ejection fraction (LVEF) before and after the operation. Compared with control group, GLS and GAS in PAF group were significantly decreased.GAS in PAF group three to six months after catheter ablation was significantly increased. Conclusions Although with normal LVEF, LV systolic function is impaired in patients with PAF. 3 D-STI technique could sensitively reflet the decline in LV myocardial deformation and systolic function.
