Cardiac electrophysiology and arrhythmias

Pulmonary vein isolation (PVI) is less effective in persistent atrial fibrillation (PerAF) than in paroxysmal atrial fibrillation (AF). However, the CAPLA (Effect of Catheter Ablation Using Pulmonary Vein Isolation With vs Without Posterior Left Atrial Wall Isolation on Atrial Arrhythmia Recurrence in Patients With Persistent Atrial Fibrillation: The CAPLA randomized clinical trial) of PVI vs posterior wall isolation (PWI) did not support empiric PWI in PerAF. We examined pulmonary vein (PV) and posterior wall (PW) electrical characteristics to determine if select patients may benefit from additional PWI.
