Cryoballoon ablation with left lateral decubitus position in atrial fibrillation patient where the left atrium was compressed by the vertebra

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...

Fracture and retrieval of an Achieve circular mapping catheter in and from a pulmonary vein during cryoballoon ablation for atrial fibrillation

Case report A 48-year-old man underwent cryoballoon ablation for symptomatic recurrent drug refractory paroxysmal AF. He was previously treated with flecainide, but it was discontinued because of inefficacy and adverse effects. Other than AF, his medical history was pertinent only for Bright disease as a child and cervical vertebral fusion. In the electrophysiology laboratory, vascular access w...

Predictors of atrial fibrillation recurrence after atrial fibrillation ablation with cryoballoon.

BACKGROUND Catheter ablation of atrial fibrillation is recommended for patients with symptomatic paroxysmal atrial fibrillation (PAF) despite anti-arrhythmic drugs (AADs). Radiofrequency ablation is widely accepted as an effective treatment for PAF. Cryoenergy by cryoballoon technique is an alternative to radiofrequency (RF) ablation. Cryoballoon ablation is safe, and has a similar success rate...

The role of left atrial deformation parameters in the prediction of atrial fibrillation recurrence after cryoballoon ablation therapy

Could successful cryoballoon ablation of paroxysmal atrial fibrillation prevent progressive left atrial remodeling?

BACKGROUND Radiofrequency catheter ablation of atrial fibrillation (AF) has been proved to be effective and to prevent progressive left atrial (LA) remodeling. Cryoballoon catheter ablation (CCA), using a different energy source, was developed to simplify the ablation procedure. Our hypothesis was that successful CCA can also prevent progressive LA remodeling. METHODS 36 patients selected for...
