Bipolar radiofrequency ablation for refractory scar-related interatrial septal tachycardias: a multicenter study.

Background: Catheter ablation of scar-related interatrial septal atrial tachycardias (IAS-ATs) is challenging and can be refractory to conventional unipolar radiofrequency catheter ablation (RFCA).

Aim: This multicenter study investigated the safety and efficacy of bipolar radiofrequency catheter ablation (Bi-RFCA) in patients with IAS-AT refractory to conventional unipolar RFCA.

Methods: Consecutive patients with scar-related IAS-AT refractory to conventional unipolar RFA across three electrophysiological centers were included in the study.

2025 International Expert Practical Guide on the Use of the Pentaspline Pulsed Field Ablation System in Atrial Fibrillation Ablation Procedures.

Pulsed field ablation (PFA) has been developed as a largely nonthermal ablation technology with a unique biophysical profile to treat atrial fibrillation. Existing evidence has shown that PFA offers a safe and efficient atrial fibrillation ablation procedure. Among different PFA technologies, the pentaspline FARAPULSE system has been the most extensively used and investigated; however, notable variability exists in workflow, fluoroscopy time, and lesion durability.

Catheter Ablation of Premature Ventricular Contractions from Right Ventricular Outflow Tract: Concept and Application of Very-High-Power, Very-Short-Duration as a First-Line Ablation Strategy.

This technical report presents a compelling case for the use of very-high-power, very-short-duration (VHPSD) radiofrequency ablation as a promising and efficient strategy for treating symptomatic premature ventricular contractions (PVCs) originating from the right ventricular outflow tract (RVOT). The patient with frequent, symptomatic PVCs and a 24% burden underwent successful ablation using a 90 W/4 s recipe via the QDOT MICRO™ catheter. The procedure resulted in immediate and sustained elimination of PVCs, with only 4 s of ablation time, near-zero fluoroscopy, no complications, and no PVC recurrence at 6 months.

Vascular access site management during electrophysiology procedures: a European Heart Rhythm Association survey.

Aims: Reliable vascular access and haemostasis techniques are important to the safety of electrophysiology (EP) procedures. This European Heart Rhythm Association (EHRA) survey aimed to evaluate contemporary vascular access site management practices across international EP centres.

Methods And Results: A 30-question survey was disseminated via the EHRA between March and April 2025, with 401 responses from professionals across 51 countries.

Technical Report of Radiofrequency Ablation of AVNRT with Persistent Left Superior Vena Cava: Success Relies on Basics.

: Persistent Left Superior Vena Cava (PLSVC) is a condition that may complicate the ablation of Atrioventricular nodal reentry tachycardia (AVNRT). We aimed to report technical experience in ablation under scuh clinical setting. : 3D guided electrophysiological procedure was conducted and PLSVC was confirmed.

Lifestyle and risk factor modification in atrial fibrillation: a European Heart Rhythm Association survey.

Aims: Lifestyle and risk factor modification (LRFM) forms a central pillar in the management of atrial fibrillation (AF). This European Heart Rhythm Association (EHRA) survey aims to assess current clinical practice regarding LRFM across EHRA countries.

Methods And Results: A 31-item questionnaire was developed and distributed amongst healthcare professionals via the EHRA and social media, between 23 September and 21 October 2024.

Impact of dispersive patch electrode positioning on safety and efficacy of radiofrequency catheter ablation.

Safe and efficient radiofrequency catheter ablation depends significantly on the proper placement of dispersive patch electrodes (DPEs), on the skin. This viewpoint describes the role of DPE positioning in optimizing lesion creation and reducing the risk of complications. Incorrect DPE placement can lead to suboptimal energy delivery, prolonging the procedure and/or increasing the risk of adverse events, such as steam pops and potentially fatal atrio-oesophageal fistula.

Effects of sodium-glucose co-transporter inhibitors on individual clinical endpoints and quality of life.

Aims: Sodium-glucose co-transporter inhibitors (SGLTis) have cardiovascular protective effects. We aimed to assess the effects of SGLTis on individual hard clinical endpoints and quality of life (QoL) in patients with cardiovascular risk factors.

Methods And Results: Data was searched in PubMed, Embase, Cochrane Library and clinicaltrials.

Short-term deceleration capacity: a novel non-invasive indicator of parasympathetic activity in patients undergoing pulmonary vein isolation.

Background: Subtypes of atrial fibrillation (AF) can differ, and exact mechanisms in which patients benefit from the pulmonary vein isolation (PVI) remain not fully understood. During PVI, vagal innervation of the heart may also be affected. Thus, non-invasive methods of intraprocedural assessment of such PVI impact are sought.

Cardioneuroablation for vasovagal syncope: insights on patients' selection, centre settings, procedural workflow and endpoints-results from an European Heart Rhythm Association survey.

Aims: Cardioneuroablation (CNA) is a catheter-based intervention for recurrent vasovagal syncope (VVS) that consists in the modulation of the parasympathetic cardiac autonomic nervous system. This survey aims to provide a comprehensive overview of current CNA utilization in Europe.

Methods And Results: A total of 202 participants from 40 different countries replied to the survey.

Improvement in Atrioventricular Conduction Using Cardioneuroablation Performed Immediately after Pulmonary Vein Isolation.

In patients with atrial fibrillation (AF) recurrences after pulmonary vein isolation (PVI), concomitant treatment using anti arrhythmic drugs (AADs) can lead to clinical success. However, patients with atrioventricular (AV) block may not be good candidates for concomitant AAD therapy due to the risk of further worsening of conduction abnormalities. Cardioneuroablation (CNA), as an adjunct to PVI, may offer a solution to this problem.

Accessory pathway localization with probabilistic density maps generated by a mobile application: Assessment of a full pre-excitation net-vector method.

Introduction: Precise electrocardiographic localization of accessory pathways (AP) can be challenging. Seminal AP localization studies were limited by complexity of algorithms and sample size. We aimed to create a nonalgorithmic method for AP localization based on color-coded maps of AP distribution generated by a web-based application.

Effect of SGLT-2 inhibitors on arrhythmia events: insight from an updated secondary analysis of > 80,000 patients (the SGLT2i-Arrhythmias and Sudden Cardiac Death).

Objective: We aimed to assess the effect of SGLT2i on arrhythmias by conducting a meta-analysis using data from randomized controlled trials(RCTs).

Background: Sodium-glucose co-transporter 2 inhibitors (SGLT2i) have shown cardioprotective effects via multiple mechanisms that may also contribute to decrease arrhythmias risk.

Methods: We searched in databases (PubMed, Embase, Cochrane Library, and clinicaltrials.
