Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The purpose of this prospective randomized study is to assess whether empirical Left Atrial Appendage (LAA) isolation along with the standard approach of pulmonary vein isolation (PVI) and ablation of extra-pulmonary triggers is superior to the standard approach alone in enhancing the long-term success rate of catheter ablation in persistent or long-standing persistent atrial fibrillation (AF) patients.
