Safety of very high-power short-duration radiofrequency ablation for pulmonary vein isolation: a two-centre report with emphasis on silent oesophageal injury.

Europace, 2021
AIMS Very high-power short-duration (vHPSD) via temperature-controlled ablation (TCA) is a new modality to perform radiofrequency pulmonary vein isolation (PVI), conceivably at the cost of a narrower safety margin towards the oesophagus.

Pulmonary vein antrum isolation

Heart Rhythm, 2007
Pulmonary vein antrum isolation offers safe and effective treatment of atrial fibrillation by eliminating the potential triggers of this arrhythmia. The pulmonary vein antra encompass, in addition to the pulmonary veins, the left atrial roof and posterior wall and, in the case of the right pulmonary vein antra, a portion of the interatrial septum ...

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 ...

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).

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 ...

Can we isolate the pulmonary veins? [PDF]

Heart Rhythm, 2014
Ablation for atrial fibrillation (AF) ranks as one of the greatest successes and a perplexing failure of contemporary cardiac electrophysiology. Despite tremendous continued enthusiasm, several experienced interventional electrophysiologists consider AF ablation as a palliative rather than a curative procedure. This likely reality has resulted from the

Use of a multi‐electrode radiofrequency balloon catheter to achieve pulmonary vein isolation in patients with paroxysmal atrial fibrillation: 12‐Month outcomes of the RADIANCE study

Cardiovascular Electrophysiology, 2020
The RADIANCE first‐in‐man study evaluated acute (3‐month) safety and design concept in terms of utility of a new multi‐electrode radiofrequency (RF) balloon catheter (HELIOSTAR, Biosense Webster) to achieve pulmonary vein isolation (PVI).

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

Isolated atresia of the left pulmonary veins

International Journal of Cardiology, 1985
Four cases of congenital isolated atresia of the left pulmonary veins were observed over a 12-year period. The diagnosis was established through radionuclide pulmonary perfusion studies together with cardiac catheterization and pulmonary arteriography.
