Acute success and short-term follow-up of catheter ablation of isthmus-dependent atrial flutter: a comparison of 8 mm tip radiofrequency and cryothermy catheters Ghent University

AS Thornton, P Janse, M Alings, MF Scholten, JM Mekel, M Miltenburg, E Jessurun, Luc Jordaens
Objectives: To compare the acute success and short-term follow-up of ablation of atrial flutter using 8 mm tip radiofrequency (RF) and cryocatheters. Methods: Sixty-two patients with atrial flutter were randomized to RF or cryocatheter (cryo) ablation. Right atrial angiography was performed to assess the isthmus. End point was bidirectional isthmus block on multiple criteria. A pain score was used and the analgesics were recorded. Patients were ...

Hybrid thoracoscopic surgical and transvenous catheter ablation versus transvenous catheter ablation in persistent and longstanding persistent atrial fibrillation (HARTCAP-AF) Vrije Universiteit Brussel

Mindy Vroomen, Mark La Meir, Justin G L Luermans, Kevin Vernooy, Brigitte A B Essers, Bianca T A de Greef, Jos G. Maessen, Harry J. G. M. Crijns, Laurent Pison

BACKGROUND: Success rates with conventional transvenous endocardial pulmonary vein isolation in patients with persistent and longstanding persistent atrial fibrillation (AF) are variable due to advanced electrical and structural remodeling of the atria. As a consequence, more extensive endocardial lesions, minimally invasive thoracoscopic surgical techniques, and hybrid ablation (combining thoracoscopic epicardial surgical and endocardial ...

Hybrid Ablation Versus Repeated Catheter Ablation in Persistent Atrial Fibrillation Vrije Universiteit Brussel

BACKGROUND: Although catheter ablation (CA) is successful for the treatment of paroxysmal atrial fibrillation (AF), results are less satisfactory in persistent AF. Hybrid ablation (HA) results in better outcomes in patients with persistent atrial fibrillation (persAF), as it combines a thoracoscopic epicardial and transvenous endocardial approach in a single procedure.

OBJECTIVES: The purpose of this study was to compare the ...

Outcomes of repeat catheter ablation using magnetic navigation or conventional ablation Ghent University

After initial catheter ablation, repeat procedures could be necessary. This study evaluates the efficacy of the magnetic navigation system (MNS) in repeat catheter ablation as compared with manual conventional techniques (MANs). The results of 163 repeat ablation procedures were analysed. Ablations were performed either using MNS (n 84) or conventional manual ablation (n 79). Procedures were divided into four groups based on the technique used ...

Paroxysmal Atrial Fibrillation Ablation Using a Novel Variable-Loop Biphasic Pulsed Field Ablation Catheter Integrated With a 3-Dimensional Mapping System: 1-Year Outcomes of the Multicenter inspIRE Study Hasselt University

Mattias Duytschaever, Tom De Potter, Massimo Grimaldi, Ante Anic, Johan VIJGEN, Petr Neuzil, Hugo Van Herendael, Atul Verma, Allan Skanes, Daniel Scherr, et al.
Background: The inspIRE study (Study for Treatment of Paroxysmal Atrial Fibrillation [PAF] by Pulsed Field Ablation [PFA] System With Irreversible Electroporation [IRE]) evaluated safety and effectiveness of a fully integrated biphasic pulsed field ablation (PFA) system with a variable-loop circular catheter for the treatment of drug-refractory paroxysmal atrial fibrillation.Methods: Subjects underwent pulmonary vein (PV) isolation with the PFA ...

Patient selection, peri-procedural management, and ablation techniques for catheter ablation of atrial fibrillation Vrije Universiteit Brussel

Radoslaw Lenarczyk, Daniel Scherr, Giulio Conte, Francisco Marin, Javier Garcia-Seara, Tatjana S Potpara

Catheter ablation (CA) of atrial fibrillation (AF) is the therapy of choice for the maintenance of sinus rhythm in patients with symptomatic AF. Time towards interventional treatment and peri-procedural management of patients undergoing AF ablation may vary in daily practice. The scope of this European Heart Rhythm Association (EHRA) survey was to report the current clinical practice regarding the management of patients undergoing AF ablation ...

Atrial fibrillation history impact on catheter ablation outcome : findings from the ESC-EHRA Atrial Fibrillation Ablation Long-Term Registry Ghent University

Giuseppe Stabile, Serge A Trines, Elena Arbelo, Nikolaos Dagres, Josep Brugada, Josef Kautzner, Evgeny Pokushalov, Aldo P Maggioni, Cecile Laroche, Matteo Anselmino, et al.
Background: Atrial fibrillation (AF) promotes atrial remodeling that in turn promotes AF perpetuation. The aim of our study is to investigate the impact of AF history length on 1-year outcome of AF catheter ablation in a cohort of patients enrolled in the Atrial Fibrillation Ablation Registry. Methods: We described the real-life clinical epidemiology, therapeutic strategies, and the short- and mid-term outcomes of 1948 patients (71.9% with ...
