Post-PVI Left Atrial Flutter Managed with Pulmonary Vein Re-Isolation Using Cryoballoon Ablation [PDF]

, 2020
A case of left atrial flutter occurring after pulmonary vein isolation effected via cryothermic balloon ablation for atrial fibrillation is presented, which was successfully managed with pulmonary vein re-isolation.

Characteristics of Phrenic Nerve Injury During Pulmonary Vein Isolation Using a 28‐mm Second‐Generation Cryoballoon and Short Freeze Strategy

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2018
BackgroundThe reported incidence of phrenic nerve injury (PNI) varies owing to different definitions, balloon generations, balloon size, freezing regimen, and protective maneuvers.

Bigeminal Pulmonary Vein Ectopy Suppressed by Pulmonary Vein Isolation

International Heart Journal, 2008
A 58-year-old man with atrial fibrillation underwent pulmonary vein (PV) isolation (PVI). Bigeminal atrial premature beats persisted from the beginning of the PVI. The cardiac recordings from a basket catheter (BC) revealed the PV ectopic origin in the distal right superior PV.

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 ...

Spontaneous and induced pulmonary vein tachycardia after pulmonary vein isolation [PDF]

Europace, 2004
A case is reported of recurrence of paroxysmal atrial fibrillation after pulmonary vein ablation. A second procedure achieved isolation of three pulmonary veins and showed persistence of pulmonary vein tachycardia in one with implications concerning the electrophysiology of atrial fibrillation.

A case of unidirectional exit block during pulmonary vein isolation [PDF]

, 2017
: We present a case of unidirectional exit block from a pulmonary vein (PV) during a pulmonary vein isolation procedure. Following circumferential antral applications around the right PVs, PV pacing showed capture without exit.

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.

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 ...

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 ...
