Pulmonary Vein Isolation vs Sham Intervention in Symptomatic Atrial Fibrillation: The SHAM-PVI Randomized Clinical Trial.

Journal of the American Medical Association (JAMA)
Importance There are concerns that pulmonary vein isolation for atrial fibrillation may have a profound placebo effect, but no double-blind randomized clinical trials have been conducted.

Pulmonary Vein Isolation With or Without Left Atrial Appendage Ligation in Atrial Fibrillation: The aMAZE Randomized Clinical Trial.

Journal of the American Medical Association (JAMA)
Importance Left atrial appendage elimination may improve catheter ablation outcomes for atrial fibrillation. Objective To assess the safety and effectiveness of percutaneous left atrial appendage ligation adjunctive to catheter pulmonary vein isolation

Marshall bundle elimination, Pulmonary vein isolation, and Line completion for ANatomical ablation of persistent atrial fibrillation (Marshall-PLAN): Prospective, single-center study.

Heart Rhythm, 2020
BACKGROUND Beyond pulmonary vein isolation (PVI), the optimal ablation strategy for persistent atrial fibrillation (AF) remains poorly defined. OBJECTIVES We sought to examine a novel comprehensive ablation strategy (Marshall-PLAN) strictly based on ...

Pulmonary vein stenosis after HotBalloon pulmonary vein isolation of paroxysmal atrial fibrillation

Heart and Vessels, 2021
HotBalloon-based pulmonary vein isolation (HBPVI) has yielded encouraging clinical results in the treatment of paroxysmal atrial fibrillation (PAF). However, pulmonary vein (PV) stenosis remains a concern. The influence of longer application duration on PV stenosis has not yet been systematically evaluated. All patients who underwent first HBPVI of PAF

Pulmonary Vein Antrum Isolation:

Journal of Cardiovascular Electrophysiology, 2004
Several techniques are used for AF ablation, but no general consensus exists as to which technique is the most effective. At our center, we have developed a technique for isolating the pulmonary veins (PVs) at their antrum. The technique is guided by intracardiac echocardiography (ICE) and mapping with a circular (Lasso) catheter.

Pulsed field ablation for pulmonary vein isolation in the treatment of atrial fibrillation

Cardiovascular Electrophysiology, 2020
Pulsed‐field ablation (PFA) is a promising new ablation modality for the treatment of atrial fibrillation. This energy form employs a train of microsecond duration high amplitude electrical pulses that ablate myocardium by electroporation of the ...

Pulmonary vein stenosis after radiofrequency pulmonary vein isolation for atrial fibrillation

Journal of the American Society of Echocardiography, 2004
A 52-year-old man presented to our institution because of recurrent episodes of atrial fibrillation and counterclockwise atrial flutter, refractory to medical therapy with different regimens including amiodarone, and after several cardioversions to restore in sinus rhythm. Coronary artery stenosis was ruled out invasively.

Total pulmonary vein occlusion complicating pulmonary vein isolation: Diagnosis and treatment

Heart Rhythm, 2010
Pulmonary vein stenosis (PVS) complicating pulmonary vein isolation (PVI) can progress to total pulmonary vein occlusion (PVO). Little is known about the accuracy of noninvasive diagnosis and treatment of PVO.The purpose of this study was to study the diagnostic accuracy of noninvasive testing and the feasibility and outcome of percutaneous ...

Cryoballoon ablation for pulmonary vein isolation

Journal of Cardiovascular Electrophysiology, 2020
AbstractOver the past 20 years, multiple studies have demonstrated the superiority of percutaneous catheter‐based pulmonary vein isolation (PVI) in the management of atrial fibrillation (AF). Unfortunately, the results of catheter ablation can be limited by arrhythmia recurrence, which is often a result of a failure to achieve durable lesions around ...

Safety and outcome of very high-power short-duration ablation using 70 W for pulmonary vein isolation in patients with paroxysmal atrial fibrillation.

Europace, 2019
AIMS Pulmonary vein isolation (PVI) using radiofrequency ablation (RFA) in patients with paroxysmal atrial fibrillation (PAF) is effective but hampered by pulmonary vein reconnection due to insufficient ablation lesions.
