Short and Intermediate Term Outcomes of the Convergent Procedure: Initial Experience in a Tertiary Referral Center [PDF]

, 2020
PURPOSE: The Convergent procedure is a hybrid, multidisciplinary treatment for symptomatic atrial fibrillation (AF) consisting of minimally invasive surgical epicardial ablation and percutaneous/catheter endocardial ablation.

Cryoballoon Versus High-Power, Short-Duration Radiofrequency Ablation for Pulmonary Vein Isolation in Patients With Paroxysmal Atrial Fibrillation

Circulation: Arrhythmia and Electrophysiology, 2021
Background: The efficacy of cryoballoon pulmonary vein isolation (Cryo-PVI) is equivalent to that of radiofrequency pulmonary vein isolation in patients with paroxysmal atrial fibrillation (AF). We aimed to compare the efficacy and safety profile of Cryo-

Standardized pulmonary vein isolation workflow to enclose veins with contiguous lesions: the multicentre VISTAX trial.

Europace, 2020
AIMS To evaluate the safety and effectiveness of pulmonary vein isolation in paroxysmal atrial fibrillation (PAF) using a standardized workflow aiming to enclose the veins with contiguous and optimized radiofrequency lesions.

Short P‐Wave Duration is a Marker of Higher Rate of Atrial Fibrillation Recurrences after Pulmonary Vein Isolation: New Insights into the Pathophysiological Mechanisms Through Computer Simulations

Journal of the American Heart Association : Cardiovascular and Cerebrovascular Disease, 2021
Background Short ECG P‐wave duration has recently been demonstrated to be associated with higher risk of atrial fibrillation (AF). The aim of this study was to assess the rate of AF recurrence after pulmonary vein isolation in patients with a short P ...

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.

Ultrasonic characterization of the pulmonary venous wall: echographic and histological correlation [PDF]

, 2002
Background: Pulmonary vein isolation with radiofrequency catheter ablation techniques is used to prevent recurrences of human atrial fibrillation. Visualization of the architecture at the venoatrial junction could be crucial for these ablative techniques.

Numerical predictions of shear stress and cyclic stretch in the healthy pulmonary vasculature [PDF]

arXiv, 2021
Isolated post-capillary pulmonary hypertension (Ipc-PH) occurs due to left heart failure, which contributes to 1 out of every 9 deaths in the United States. In some patients, through unknown mechanisms, Ipc-PH transitions to combined pre-/post-capillary PH (Cpc-PH), diagnosed by an increase in pulmonary vascular resistance and associated with a ...

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.

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.

Role of non-pulmonary vein triggers in persistent atrial fibrillation

International Journal of Arrhythmia, 2023
Pulmonary vein isolation is an well-established treatment strategy for atrial fibrillation (AF), and it is especially effective for patients with paroxysmal AF.
