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

Claudia A. J. van der Heijden, Vanessa Weberndörfer, Mindy Vroomen, Sevasti-Maria Chaldoupi, Elham Bidar, Kevin Vernooy, Jos G. Maessen, Laurent Pison, Sander M J van Kuijk

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 ...

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 Universiteit Hasselt

Johan VIJGEN
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 ...

Caudal vena cava isolation using ablation index-guided radiofrequency catheter ablation (CARTO™ 3) to treat sustained atrial tachycardia in horses Universiteit Gent

Eva Buschmann, Glenn Van Steenkiste, Ingrid Vernemmen, Marie Demeyere, Stijn Schauvliege, Annelies Decloedt, Gunther van Loon
Background: Myocardial sleeves of the caudal vena cava are the predilection site for atrial tachycardia (AT) in horses. Caudal vena cava isolation guided by the ablation index, a lesion quality marker incorporating power, duration and contact force, might improve outcome.ObjectivesDescribe the feasibility and outcome of caudal vena cava isolation using ablation index-guided radiofrequency catheter ablation (RFCA) to treat AT in horses. Animals: ...

Redo ablation procedures to treat recurrent atrial arrhythmias via a pentaspline pulsed field ablation catheter Vrije Universiteit Brussel

María Cespón-Fernández, Domenico Della Rocca, Michele Magnocavallo, Andrés Betancur, Ilenia Lombardo, Luigi Pannone, Giampolo Vetta, Antonio Sorgente, Marco Polselli, Charles Audiat, et al.

BACKGROUND: Patients undergoing atrial fibrillation (AF) catheter ablation may require redo procedures involving pulmonary vein (PV) re-isolation and/or ablation of extra-PV sites. Pulsed field ablation (PFA) offers a highly selective energy source for cardiac tissue, with the potential to reduce collateral damage to adjacent structures. This study aimed to evaluate the feasibility and efficacy of redo ablation using a pentaspline PFA ...

Catheter Ablation of Atrial Fibrillation: identifying predictors of ablation success to guide a patient-tailored treatment Universiteit Antwerpen

Marco Bergonti
Atrial fibrillation (AF) is the most common cardiac arrhythmia, and its prevalence is expected to rise. After two decades of controversy over the best treatment strategy for AF patients (rate vs rhythm control), the balance is slightly tilting back towards the latter, at least in patients early after diagnosis (i.e. ≤ 1 year) and those with heart failure (HF). Moreover, clinical trials have demonstrated the superiority of early ablation compared ...
