Very high-power short-duration using 70W and a flexible tip ablation catheter for pulmonary vein isolation: the POWER PULSE randomized controlled trial

Miruna A. Popa, Hannah Krafft, Fabian Bahlke, Florian Englert et autres

AIMS: Very high-power short-duration (vHPSD) was developed to optimize radiofrequency ablation for atrial fibrillation (AF). However, data on vHPSD ≥ 70W remains limited. We investigated acute efficacy, safety and long-term rhythm outcomes of vHPSD-70W in a randomized controlled trial. METHODS AND RESULTS: …

The long-term outcome of pulmonary vein isolation in paroxysmal atrial fibrillation is significantly influenced by diabetes mellitus in general as well as by an antidiabetic therapy

Jan R. Reichl, F Bourier, Isabel Deisenhofer, Gabriele Hessling et autres

Abstract Introduction Over the last decades pulmonary vein isolation became a cornerstone in the interventional treatment of paroxysmal atrial fibrillation. Postprocedural recurrences of atrial fibrillation are present in patients with and without concomitant cardiovascular diseases. Purpose The aim of this study was …

Valvular leaflets and epicardial fat have a significant effect on lesion size in RF ablation

Cindy L. Colling, Tilko Reents, Marc Kottmaier, Florian Englert et autres

Abstract Introduction Radiofrequency (RF) current is the classic ablation technology in the EP lab. Underlying RF ablation parameters, such as RF power, impedance, duration and contact force are used to calculate expected lesion size. Furthermore, lesion indices (LSI, AI) are applied to …

Pulsed field ablation in patients with cardiac implantable electronic devices: an ex vivo assessment of safety

Carsten Lennerz, Matthew O’Connor, Claudia Schaarschmidt, Tilko Reents et autres

BACKGROUND: Pulse field ablation (PFA) is a novel catheter ablation technology with potential safety benefits due to its tissue selectivity. It has the potential to directly damage or interact with the functionality of cardiac implantable electronic devices (CIEDs) in the form of …

Associations between atrial epicardial fat quantified by semi-automated CT segmentation and gender, BMI, cholesterol levels in AF patients: results from the prospective AFAT study

Nico Erhard, Simon Prommersberger, Bruno Neuner, Fabian Bahlke et autres

Abstract Background Epicardial adipose tissue (EAT) is defined as adipose tissue (epicardial fat) between the myocardium and the visceral pericardium. Recent evidence suggests that EAT may play important roles in regard to atrial fibrillation (AF) burden as well as other cardiovascular diseases …

Comparing pulsed field electroporation and radiofrequency ablation for the treatment of paroxysmal atrial fibrillation: design and rationale of the BEAT PAROX-AF randomized clinical trial

Nico Erhard, Éric Frison, Julien Asselineau, Besma Aouar et autres

AIMS: Using thermal-based energy sources [radiofrequency (RF) energy/cryo energy] for catheter ablation is considered effective and safe when performing pulmonary vein isolation (PVI) in patients with paroxysmal atrial fibrillation (AF). However, treatment success remains limited and complications can occur due to the …

First clinical data on artificial intelligence‐guided catheter ablation in long‐standing persistent atrial fibrillation

Fabian Bahlke, Florian Englert, Miruna A. Popa, Felix J. Bourier et autres

INTRODUCTION: Despite advanced ablation strategies and major technological improvements, treatment of persistent atrial fibrillation (AF) remains challenging and the underlying pathophysiology is not fully understood. This study analyzed the multiple procedure outcome and safety of catheter ablation of spatiotemporal dispersions (DISPERS) detected …

VT ablation based on CT imaging substrate visualization: results from a large cohort of ischemic and non-ischemic cardiomyopathy patients

Florian Englert, Fabian Bahlke, Hannah Krafft, Miruna A. Popa et autres

INTRODUCTION: The eradication of ventricular tachycardia (VT) isthmus sites constitutes the minimal procedural endpoint for VT ablation procedures. Contemporary high-resolution computed tomography (CT) imaging, in combination with computer-assisted analysis and segmentation of CT data, facilitates targeted elimination of VT isthmi. In this …
