Left atrial volume predicts atrial fibrillation recurrence after radiofrequency ablation: a meta-analysis

Left atrial (LA) diameter is a predictor of atrial fibrillation (AF) recurrence following radiofrequency catheter ablation (RFA). However, LA volume (LAV) is more accurate in assessing LA size. Studies evaluating LAV as a predictor of AF recurrence are contradictory; therefore, we performed a meta-analysis to assess whether LAV is an independent predictor of AF recurrence following RFA. All studies reporting LAV/LAV index (LAVi) as a predictor...
