Why the study?
Does substrate modification after CPVI improve procedural success and reduce left atrial diameter in patients with paroxysmal atrial fibrillation and low-voltage/scar areas?
Does substrate modification after CPVI improve procedural success and reduce left atrial diameter in patients with paroxysmal atrial fibrillation and low-voltage/scar areas?
High-density mapping-guided substrate modification in addition to CPVI improves 1-year procedural success and reduces left atrial diameter in paroxysmal AF patients with low-voltage or scar areas.
