Laser Balloon or Wide-Area Circumferential Irrigated Radiofrequency Ablation for Persistent Atrial Fibrillation

Radiofrequency ablation for atrial fibrillation

Comparing Safety and Efficacy of Irrigated Radiofrequency Catheter Ablation Versus Combined Cryoballoon and Catheter Ablation for Persistent Atrial Fibrillation.

Background: Catheter and cryoballoon ablation are established treatments for atrial fibrillation. Frequently, substrate modification of the left atrium is performed in patients with persistent AF or evidence of left atrial adverse remodeling. We compared one year outcomes of AF ablation with substrate modification utilizing radiofrequency catheter ablation (RFA) compared to a combination of cry...

Rhabdomyolysis complicating percutaneous radiofrequency ablation of persistent atrial fibrillation

Introduction Atrial fibrillation (AF) is the most common sustained arrhythmia in the adult population. Invasive treatment of paroxysmal and persistent AF with radiofrequency ablation is a well-recognized and effective treatment in appropriately selected patients. Higher numbers of patients are being treated with radiofrequency ablation for symptomatic paroxysmal and persistent AF. AF is associa...

Conversion of Persistent Atrial Fibrillation After Radiofrequency Ablation by Ibutilide.

Ablation of peristent AF remains challenging with questions unanswered about what the ideal next step after pulmonary venous isolation should be. Ibutilide is a highly effective class III agent for cardioversion of acute-onset atrial flutter and fibrillation, with limited clinical use due to risks of ventricular pro-arrhythmias. However, results from the on-going MAGIC-AF trial may re-invigorat...

Cryoballoon or Radiofrequency Ablation for Paroxysmal Atrial Fibrillation.

BACKGROUND Current guidelines recommend pulmonary-vein isolation by means of catheter ablation as treatment for drug-refractory paroxysmal atrial fibrillation. Radiofrequency ablation is the most common method, and cryoballoon ablation is the second most frequently used technology. METHODS We conducted a multicenter, randomized trial to determine whether cryoballoon ablation was noninferior t...
