Sex differences in overweight and obese patients undergoing high-power short-duration pulmonary vein isolation for atrial fibrillation: an observational cohort study.

Atrial fibrillation (AF) is the most common heart rhythm disorder worldwide. As treatment methods evolve, optimizing personalized therapy based on patient characteristics, such as sex, becomes crucial. This study investigates sex differences in high-power short-duration (HPSD) pulmonary vein isolation (PVI) in overweight and obese patients.

Focal Pulsed Field Ablation for Atrial Arrhythmias: Efficacy and Safety under Deep Sedation.

Focal pulsed field ablation (PFA) is a novel technique for treating cardiac arrhythmias. It has demonstrated positive results in initial studies and has a good safety profile. In recent studies, PFA was often utilized for first-time pulmonary vein isolation (PVI) and was performed under general anesthesia.

Sex-Specific Disparities in Outcomes of Transcatheter Edge-to-Edge Repair for Mitral Regurgitation: A Multicenter "Real-World" Analysis.

Background: mitral regurgitation (mr) is the most common valvular heart disease (vhd) in the elderly and tends to be more prevalent in women. while relevant sex differences in outcomes are evident in surgically treated collectives, there are very limited and conflicting sex-specific data for the growing cohort of patients undergoing transcatheter edge-to-edge repair (teer).

Objective: to investigate whether sex impacts procedural safety and efficacy, and in-hospital- and long-term outcomes, after teer for mr.

Recurrent Atrial Fibrillation Ablation after Initial Successful Pulmonary Vein Isolation.

Background: Pulmonary vein isolation (PVI) is an effective treatment option for patients with symptomatic atrial fibrillation (AF). However, the electrical recovery of pulmonary veins (PVs) is the main trigger for AF recurrences. This study investigates the characteristics of patients admitted for redo AF ablation, the PV reconnection rates depending on previous ablation modalities and the impact of different ablation strategies for redo procedures.

Catheter ablation of concomitant atrial fibrillation improves survival of patients undergoing transcatheter edge-to-edge mitral valve repair.

Background: Atrial fibrillation (AF) is the most common concomitant disease in patients undergoing transcatheter edge-to-edge repair (TEER) for mitral regurgitation (MR) and detrimentally affects their outcome. While there is increasing evidence for prognostic improvement and safety of catheter ablation (CA) of AF in the overall cohort of heart failure patients, corresponding data in TEER patients are lacking.

Objectives: To investigate the impact of treatment regimens for concomitant AF on survival of TEER patients.
