Paroxysmal atrial fibrillation ablation: Achieving permanent pulmonary vein isolation by point-by-point radiofrequency lesions
Pulmonary vein isolation by point-by-point radiofrequency catheter ablation constitutes the cornerstone of catheter ablation strategies for the treatment of atrial fibrillation. However, despite advances in pulmonary vein isolation ablation strategies, long-term success rates after ablation remain suboptimal, which highlights the need to develop techniques to achieve more durable lesions. Strat...
متن کاملFirst-line catheter ablation of paroxysmal atrial fibrillation: outcome of radiofrequency vs. cryoballoon pulmonary vein isolation.
AIMS First-line ablation prior to antiarrhythmic drug (AAD) therapy is an option for symptomatic paroxysmal atrial fibrillation (PAF); however, the optimal ablation technique, radiofrequency (RF), or cryoballoon (CB) has to be determined. METHODS AND RESULTS The FREEZE Cohort Study compares RF and CB ablation. Treatment-naïve patients were documented in the FREEZEplus Registry. Periprocedural...
متن کاملPulmonary vein isolation as an end point for left atrial circumferential ablation of atrial fibrillation.
OBJECTIVES We sought to determine whether elimination of pulmonary vein (PV) arrhythmogenicity is necessary for the efficacy of left atrial circumferential ablation (LACA) for atrial fibrillation (AF). BACKGROUND The PVs often provide triggers or drivers of AF. It has been shown that LACA is more effective than PV isolation in eliminating paroxysmal AF. However, it is not clear whether comple...
متن کاملPulmonary vein isolation by circumferential radiofrequency lesions in atrial fibrillation. From substrate to clinical outcome.
Circumferential ablation around pulmonary vein ostia by CARTO system was performed in 98 patients with paroxysmal and 29 with permanent atrial fibrillation (AF). Preablation and postablation activation, propagation and voltage maps were obtained. A total of 135 +/- 18 radiofrequency pulses were delivered. After a follow-up of 14.7 +/- 3.3 months, 84 patients with paroxysmal and 22 with chronic ...
متن کاملPulmonary vein isolation for paroxysmal and persistent atrial fibrillation.
BACKGROUND The pulmonary veins (PVs) have been demonstrated to often play an important role in generating atrial fibrillation (AF). The purpose of this study was to determine the safety and efficacy of segmental PV isolation in patients with paroxysmal or persistent AF. METHODS AND RESULTS In 70 consecutive patients (mean age, 53 +/- 11 years) with paroxysmal (58) or persistent (12) AF, segme...
