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 کاملVisual balloon-guided point-by-point ablation: reliable, reproducible, and persistent pulmonary vein isolation.
BACKGROUND While conceptually straightforward, placing point-to-point contiguous radiofrequency lesions to achieve pulmonary vein isolation (PVI) is technically challenging in patients with paroxysmal atrial fibrillation. Furthermore, chronic efficacy is limited by late PV reconnections. A novel compliant balloon ablation catheter able to deliver visually guided short arcs/spots of laser energy...
متن کاملA Randomized Comparison of Circular versus Single Point-By-Point Pulmonary Vein Isolation
Introduction: Point-by-point standard ablation using single-tip (conventional) catheter is the main current technique for pulmonary vein isolation (PVI) but it can be challenging. A circular, multielectrode, mapping and ablation catheter (nMARQ) may provide faster PVI. Methods: We designed a randomized comparison between circular versus conventional PVI with the primary end point of reconnectio...
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 using multi-electrode radiofrequency vs conventional point-by-point radiofrequency ablation: A meta-analysis of randomized and non-randomized studies
AIMS Pulmonary vein isolation is effective in reducing atrial fibrillation (AF) episodes. Previous studies suggest single-shot techniques are effective and safe for this purpose. Procedural and clinical outcomes were compared between multi-electrode and point-by-point radiofrequency ablations by performing a meta-analysis of all randomized and non-randomized studies. METHODS AND RESULTS Syste...
