Why the study?
Does posterior wall isolation (PWI) during atrial fibrillation ablation improve 12-month freedom from atrial arrhythmia and safety in patients undergoing atrial fibrillation ablation?
Does posterior wall isolation (PWI) during atrial fibrillation ablation improve 12-month freedom from atrial arrhythmia and safety in patients undergoing atrial fibrillation ablation?
Posterior wall isolation during AF ablation is feasible and provides good 12-month arrhythmia freedom, but carries a persistent risk of atrio-esophageal fistula.
Answers are grounded in this paper and cite their sources.
Supports PWI in AF ablation for arrhythmia control; extends systematic evidence while underscoring persistent fistula risk.
PWI as an end point of AF ablation can be achieved in a large proportion of cases with good rates of 12-month freedom from atrial arrhythmia. Although the procedure-related complication rate is low, it did not eliminate the risk of atrio-esophageal fistula. Registration: URL: http://www.crd.york.ac.uk/prospero.
