Evaluating Pulmonary Vein Isolation [PDF]

Journal of Arrhythmia, 2008
Pulmonary vein isolation is the electrophysiological endpoint of complete conduction block at the level of the veno-atrial junction and must be explicitly distinguished from encircling PV ablation which frequently does not result in isolation.

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 ...

Emerging Technologies for Pulmonary Vein Isolation [PDF]

Circulation Research, 2020
Atrial fibrillation is the most common sustained cardiac arrhythmia and is associated with considerable morbidity and mortality. Electrically isolating the pulmonary veins from the left atrium by catheter ablation is superior to antiarrhythmic drug therapy for maintaining sinus rhythm, but its success varies depending on multiple factors, including ...

Complications of Cryoballoon Pulmonary Vein Isolation

Arrhythmia & Electrophysiology Review, 2019
Since the cryoballoon (CB) was introduced into clinical practice, more than 400,000 patients have undergone a pulmonary vein (PV) isolation with a CB throughout the world. Although the efficacy of the first-generation CB was limited, the recently introduced secondgeneration CB has achieved a greater uniformity in cooling, which has facilitated a ...

Pulmonary Vein Isolation With Optimized Linear Ablation vs Pulmonary Vein Isolation Alone for Persistent AF: The PROMPT-AF Randomized Clinical Trial.

JAMA
Importance Success rates of pulmonary vein isolation (PVI) are modest for persistent atrial fibrillation (AF). Additional linear ablation beyond PVI has not been proved superior to PVI alone in randomized trials. Ethanol infusion of the vein of Marshall (

Methods and techniques for increasing the safety and efficacy of pulmonary vein isolation in patients with atrial fibrillation [PDF]

Folia Medica, 2023
The most common type of sustained arrhythmia is atrial fibrillation (AF). Pulmonary vein isolation (PVI) is the cornerstone of catheter ablation for atrial fibrillation, which has emerged as the primary therapeutic strategy for atrial fibrillation ...

Effect of Catheter Ablation Using Pulmonary Vein Isolation With vs Without Posterior Left Atrial Wall Isolation on Atrial Arrhythmia Recurrence in Patients With Persistent Atrial Fibrillation: The CAPLA Randomized Clinical Trial.

Journal of the American Medical Association (JAMA), 2023
Importance Pulmonary vein isolation (PVI) alone is less effective in patients with persistent atrial fibrillation (AF) compared with paroxysmal AF.

Pulsed Field Versus Cryoballoon Pulmonary Vein Isolation for Atrial Fibrillation: Efficacy, Safety, and Long-Term Follow-Up in a 400-Patient Cohort

Circulation: Arrhythmia and Electrophysiology, 2023
BACKGROUND: The cryoballoon (CB) represents the gold standard single-shot device for pulmonary vein isolation (PVI) in patients with atrial fibrillation (AF).
