DOES TERMINATION OF ATRIAL FIBRILLATION DURING ABLATION OF LONG STANDING PERSISTENT ATRIAL FIBRILLATION PREDICT THE OUTCOME AT FOLLOW-UP? RESULTS FROM A PROSPECTIVE RANDOMIZED STUDY

In patients with persistent and long standing persistent (LSP) atrial fibrillation (AF) in addition to pulmonary vein isolation (PVI), extensive substrate modification and Non PV triggers ablation is important to achieve long term success. Whether AF termination during ablation should be considered
