Extensive left atrial ablation was associated with exacerbation of left atrial stiffness and dyspnea

Introduction The left atrium (LA), including the pulmonary vein antrum, is the main target of catheter ablation for atrial fibrillation (AF). However, there is a lack of data on the effect of extensive LA ablation on LA stiffness. This study sought to investigate the impact of extensive LA ablation on LA stiffness and dyspnea after the restoration of sinus rhythm. Methods In total, 97 patients with AF (80 patients who only underwent pulmonary...
