Outcomes of Pulmonary Vein Isolation in Athletes

JACC: Clinical Electrophysiology, 2020
The aims of this study were to assess outcomes of pulmonary vein isolation (PVI) performed on athletes at a tertiary care center and to characterize its efficacy and physiological effects.The incidence of atrial fibrillation (AF) is increased in highly trained athletes and poses unique management challenges.Athletes were identified through a database ...

Sinus node injury during adjunctive superior vena cava isolation in a patient with triggered atrial fibrillation

Indian Pacing and Electrophysiology Journal, 2016
Introduction: Atrial fibrillation is the most common sustained heart arrhythmia. Premature beats arising from foci other than pulmonary veins have been related to its pathogenesis.

Cryoballoon Pulmonary Vein Isolation with Real‐Time Recordings from the Pulmonary Veins [PDF]

Journal of Cardiovascular Electrophysiology, 2009
Introduction: Cryoballoon (CB) ablation represents a novel technology for pulmonary vein isolation (PVI). We investigated feasibility and safety of CB‐PVI, utilizing a novel spiral catheter (SC), thereby obtaining real‐time PV potential registration.

One-year outcomes of wide antral cryoballoon ablation guided by high-density mapping vs. conventional cryoballoon ablation for atrial fibrillation: a propensity score–matched study

Frontiers in Cardiovascular Medicine
BackgroundPulmonary vein isolation with wide antral ablation leads to better clinical outcomes for the treatment of atrial fibrillation, but the isolation lesion is invisible in conventional cryoballoon ablation.

Characterization of Atrial Substrate to Predict the Success of Pulmonary Vein Isolation: The Prospective, Multicenter MASH‐AF II (Multipolar Atrial Substrate High Density Mapping in Atrial Fibrillation) Study

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2023
Background Left atrial substrate may have mechanistic relevance for ablation of atrial fibrillation (AF). We sought to analyze the relationship between low‐voltage zones (LVZs), transition zones, and AF recurrence in patients undergoing pulmonary vein ...

Electrophysiological evaluation of pulmonary vein isolation [PDF]

Europace, 2009
Electrophysiologically demonstrated complete conduction block at the level of the veno-atrial junction is preferable as the endpoint of pulmonary vein (PV) ablation rather than circumferential periostial radiofrequency delivery. Knowledge of the individual anatomy of the PVs and the left atrium (LA), appropriate positioning of circular mapping ...

How to perform pulmonary vein isolation [PDF]

EP Europace, 2004
The advent of technology for the delivery of radiofrequency energy via electrode catheters, in the late 1980s, led to the perfection of techniques for the ablation of accessory pathways and classical flutter [1–4]. This has been so successful that these substrates for arrhythmia are rarely seen in the Western world.

A rare case of right heart failure with the necessity for veno‐arterial extracorporeal membrane oxygenation following pulmonary vein stenosis after radiofrequency ablation for atrial fibrillation

Pulmonary Circulation, 2023
Pulmonary vein stenosis (PVS) after radiofrequency energy‐mediated percutaneous pulmonary vein isolation as a treatment option for atrial fibrillation is a serious complication and the prevalence in historical reports varies between 0% and 42%.
