In the last three decades, ablation of atrial fibrillation (AF) has become an evidence-based
safe and efficacious treatment for managing the most common cardiac arrhythmia. In 2007 …

Background Pulmonary vein isolation (PVI) is the cornerstone of catheter ablation of atrial
fibrillation (AF); however, the results are suboptimal for persistent AF. The left atrial posterior …

Background Gaps in the roof line have been ascribed to epicardial conduction using the
septopulmonary bundle. Objectives We sought to evaluate the frequency of septopulmonary …

Objectives The aim of this multicenter, randomized, single-blind study was to prospectively
evaluate the short-and long-term outcomes of pulmonary vein isolation (PVI) versus PVI with …

Background Prior studies have demonstrated clinical benefits associated with cryoballoon
pulmonary vein isolation (PVI) and concomitant posterior wall isolation (PWI) in patients with …

The absence of strategies to consistently and effectively address nonparoxysmal atrial
fibrillation by nonpharmacological interventions has represented a long-standing treatment …

Purpose There is a growing interest in performing pulmonary vein isolation (PVI) with
concomitant posterior wall isolation (PWI) using the cryoballoon for the treatment of patients …

Although cryoballoon ablation of atrial fibrillation (AF) has been traditionally guided by
pulmonary vein (PV) occlusion, there is evidence and growing interest in performing …

Evidence has accumulated over the last century of the importance of a critical electrical
mass in sustaining atrial fibrillation (AF). AF ablation certainly reduces electrically …

The pericardium of the human heart has received increased attention in recent times due to
interest in the epicardial approach for cardiac interventions to treat cardiac arrhythmias …
