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 ...

The anatomical basis behind the neuromodulation effects associated with pulmonary vein isolation

Cardiovascular Electrophysiology, 2021
The anatomical basis underlying the neuromodulation effects seen with pulmonary vein (PV) isolation (PVI) is not fully understood. Left atrial (LA) electro‐anatomical maps of 38 patients who underwent catheter cardioneuroablation for vagally mediated ...

Orientation of the right superior pulmonary vein affects outcome after pulmonary vein isolation.

European Heart Journal-Cardiovascular Imaging, 2021
AIMS Controversial results have been published regarding the influence of pulmonary vein (PV) anatomical variations on outcomes after pulmonary vein isolation (PVI).

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.

Is Empirical Four Pulmonary Vein Isolation Necessary for Focally Triggered Paroxysmal Atrial Fibrillation? Comparison of Selective Pulmonary Vein Isolation Versus Empirical Four Pulmonary Vein Isolation

Journal of Cardiovascular Electrophysiology, 2008
Background: We questioned whether the empirical four pulmonary vein (PV) isolation (EmPVI) was necessary in patients with paroxysmal atrial fibrillation (PAF) triggered from clearly and reproducibly defined arrhythmogenic PVs.
