Pulmonary vein antral isolation using an open irrigation ablation catheter for the treatment of atrial fibrillation: a randomized pilot study.
OBJECTIVES We sought to test how catheter ablation using an open irrigation catheter (OIC) compares with standard catheters for pulmonary vein antrum isolation. BACKGROUND Open irrigation catheters have the advantage of delivering greater power without increasing the temperature of the catheter tip, which enables deeper and wider lesions without the formation of coagulum on catheters. METHO...
متن کاملPulmonary vein isolation for atrial fibrillation.
Nonpharmacological treatment for atrial fibrillation (AF) has evolved dramatically over the past 20 years. Pulmonary vein isolation, a catheter ablation technique developed in the last decade, prevents focal triggers in the pulmonary veins from initiating episodes of AF. Although the procedure initially involved focal ablation with a catheter directly in the pulmonary veins, investigators subse...
متن کاملPercutaneous Pulmonary Vein Angioplasty for the Pulmonary Vein Stenosis After Catheter Ablation of Atrial Fibrillation
Pulmonary vein (PV) stenosis after radiofrequency catheter ablation (RFCA) of atrial fibrillation (AF) is one of the frequent complications. Percutaneous PV angioplasty and stent implantation have been used as an effective therapy for this condition, yet the in-stent restenosis rate tends to increase after stent implantation at the stenotic PVs. This seems to be caused by neointimal hyperplasia...
متن کاملPulmonary vein isolation using transvenous catheter cryoablation for treatment of atrial fibrillation without risk of pulmonary vein stenosis.
OBJECTIVES We sought to evaluate the efficacy and safety of pulmonary vein (PV) isolation using transvenous cryoablation for the treatment of atrial fibrillation (AF). BACKGROUND Although electrical isolation of PVs with radiofrequency energy for the treatment of AF is feasible, it is associated with a significant risk of PV stenosis. Cryoablation is a new alternative therapy allowing ablatio...
متن کاملPulmonary vein stenosis after catheter ablation for atrial fibrillation.
Tree randomized trials (PIAF, AFFIRM, and RACE)1-3 recently showed that rate control was not inferior compared to rhythm control for treatment of patients with atrial fibrillation (AF). However, it should be noted that frequent recurrences of AF and adverse effects of drugs decrease the potential benefits of rhythm control, prompting discontinuation of failed drugs in up to 40% of patients.2 In...
