Pulmonary vein (PV) isolation remains the cornerstone of atrial fibrillation (AF) ablation. Cryoballoon ablation is shown to be non-inferior to radiofrequency ablation in terms of efficacy and safety among paroxysmal AF patients. In this case, we report an intraprocedural adverse event encountered during cryoballoon ablation. A 46-year-old male patient with(More)
Ablation of atrial fibrillation is an established treatment for the management of patients with paroxysmal and persistent atrial fibrillation. The complex pathophysiology of persistent atrial fibrillation has fuelled the concept of adjunctive substrate modification on top of pulmonary vein isolation.
