文摘To the Editor:Atrial fibrillation(AF)is a well-recognized cause of left atrial(LA)structural remodeling.[1]LA sphericity(LASP),a new shape-based remodeling parameter,is an independent predictor for AF ablation outcome.[2,3]Improvement of LA structure was defined as LA reverse remodeling(RR).This study compared the impact of combined left atrial appendage(LAA)closure(LAAC)and catheter ablation(CA)of AF with a single procedure on LA volume(LAV)and LASP.
