Early detection of pulmonary vein reconnection after isolation in patients with paroxysmal atrial fibrillation: a comparison of ATP-induction and reassessment at 30 minutes postisolation.

abstract：INTRODUCTION:The success of pulmonary vein isolation (PVI) for atrial fibrillation (AF) may be improved if stable AF sources identified by Focal Impulse and Rotor Mapping (FIRM) are also eliminated. The long-term results of this approach are unclear outside the centers where FIRM was developed; thus, we assessed outcom...

abstract：BACKGROUND:Stroke risk is a significant concern in patients with atrial fibrillation (AF). Low stroke risk patients (CHADS2 VASc 0-2) are often treated long-term with aspirin after catheter ablation. Defining the long-term risks versus benefits of aspirin therapy, after an ablation, is essential to validate this common...
