Impact of left atrial posterior wall isolation on arrhythmia outcomes in patients with atrial fibrillation undergoing repeat ablation.

ABSTRACT:

Background

It remains unclear whether additional left atrial posterior wall isolation (LAPWI) beyond pulmonary vein reisolation (PVRI) is beneficial in atrial fibrillation (AF) patients undergoing repeat ablation.

Objective

We sought to assess impact of LAPWI on arrhythmia outcomes in patients undergoing repeat AF ablation.

Methods

All AF patients that underwent repeat ablation between January 2016 and December 2018 were included. Those undergoing PVRI only served as control, whereas those undergoing LAPWI (with or without PVRI) were the study group. Primary endpoint was freedom from atrial arrhythmias (AA) off antiarrhythmic drugs (AADs) at 1 year follow-up. Secondary endpoint was freedom from AA on/off AADs at 1 year follow-up.
