LEFT ATRIAL HEMODYNAMIC CHANGES FOLLOWING RADIOFREQUENCY ABLATION FOR ATRIAL FIBRILLATION

More extensive radiofrequency ablation (RFA) may increase freedom from atrial fibrillation (AF). However, RFA-related scarring can lead to left atrial (LA) stiffness and worsening symptoms. We evaluated change in mean LA pressure (mLAP) and compliance after RFA and compared more versus less
