The Lead Episode 129: A Discussion of Worldwide Chronic Retrieval Experience of the Helix Fixation Leadless Cardiac Pacemaker 12/11/2025

The Lead Episode 129: A Discussion of Worldwide Chronic Retrieval Experience of the Helix Fixation Leadless Cardiac Pacemaker Join Tina Baykaner, MD, MPH, HRS Digital Education Committee Vice-Chair, and her guests Mikhael F. El-Chami, MD, FHRS and Devi G. Nair, MD, FHRS for this week's Lead episode. This article summarizes the worldwide experience retrieving chronically implanted active helix-fixation leadless ventricular pacemakers (the Aveir/Abbott platform) across regulatory clinical trials. The authors assess real-world feasibility, procedural techniques, success rates, and complications of retrieval after long dwell times, demonstrating that devices can be removed safely and effectively even years after implant—up to about 9 years in follow-up. Overall, chronic retrieval success remained high with a low rate of serious adverse events, supporting helix-fixation leadless systems as a manageable long-term pacing strategy when replacement or removal is needed. Learning Objectives Explain the clinical indications for chronic retrieval of helix-fixation leadless pacemakers and how these differ from tine-fixation platforms. Summarize the reported worldwide chronic retrieval success rates, implant-duration range, and key procedural or anatomic reasons for retrieval failure. Identify practical procedural considerations (e.g., docking-button access, retrieval catheter use, imaging support) that improve the likelihood of safe long-term leadless pacemaker removal.

The Lead Episode 128: A Discussion of Long-Term Anticoagulation Discontinuation After Catheter Ablation for Atrial Fibrillation: The ALONE-AF Randomized Clinical Trial 12/04/2025

The Lead Episode 128: A Discussion of Long-Term Anticoagulation Discontinuation After Catheter Ablation for Atrial Fibrillation: The ALONE-AF Randomized Clinical Trial Join Phillip Cuculich, MD and his guests Tina Baykaner, MD, MPH and Atul Verma, MD, FHRS for this lively discussion of a cutting edge topic. The ALONE-AF trial evaluated whether patients who remained free of atrial fibrillation for at least one year after catheter ablation could safely discontinue long-term oral anticoagulation. In this randomized study of more than 800 patients, stopping anticoagulation resulted in similarly low rates of stroke or systemic embolism and significantly fewer major bleeding events compared with continuing therapy. The findings suggest that, in carefully selected post-ablation patients, long-term anticoagulation discontinuation may be a safe and beneficial strategy. Learning Objectives Evaluate the methodology and patient selection criteria of the ALONE-AF randomized trial to understand which post-ablation patients may be appropriate candidates for long-term anticoagulation discontinuation. Interpret the trial’s primary and secondary outcomes to assess the comparative risks of thromboembolism and major bleeding in patients who discontinue versus continue oral anticoagulation after successful AF ablation. Discuss the clinical implications of ALONE-AF for shared decision-making, guideline considerations, and the development of individualized anticoagulation strategies following catheter ablation.

The Lead Episode 126: A Discussion of Transcutaneous Electrical Vagus Nerve Stimulation to Suppress Premature Ventricular Contractions: A Crossover, Randomized Clinical Trial (NoVa-PVC) 11/13/2025

The Lead Episode 126: A Discussion of Transcutaneous Electrical Vagus Nerve Stimulation to Suppress Premature Ventricular Contractions: A Crossover, Randomized Clinical Trial (NoVa-PVC) Join host and Digital Education Committee Member Sandeep A Saha, MD, MS, FHRS for this lively discussion with his colleagues Charles A. Henrikson, MD, MPH, FHRS and Arun R. Mahankali Sridhar, MBBS, MPH, FACC. About this Article: In patients with symptomatic premature ventricular complexes (PVCs) refractory to medical therapy, non-invasive low-level tragus stimulation of the auricular branch of the vagus nerve significantly reduced median PVC burden compared to sham stimulation (median reduction ~13.4% vs ~8.6%; P = 0.021). The findings suggest that autonomic neuromodulation via transcutaneous vagal stimulation may offer a novel adjunctive therapy for frequent PVCs, although further larger trials are needed to evaluate long-term outcomes. Learning Objectives Describe the rationale and mechanism by which transcutaneous vagus nerve stimulation (tVNS) may modulate autonomic tone and reduce premature ventricular contractions. Summarize the design, methods, and key outcomes of the NoVa-PVC randomized crossover trial evaluating tVNS for symptomatic PVC reduction. Evaluate the clinical implications, limitations, and potential future applications of noninvasive neuromodulation as a therapeutic approach for ventricular arrhythmias.

The Lead Episode 125: A Discussion of Permanent Left Bundle Branch Area DF-4 Defibrillator Lead Implantation Feasibility, Procedural Caveats, Safety, and Follow-Up, LIVE at HRX 11/06/2025

The Lead Episode 125: A Discussion of Permanent Left Bundle Branch Area DF-4 Defibrillator Lead Implantation Feasibility, Procedural Caveats, Safety, and Follow-Up, LIVE at HRX Description Join host and HRS Digital Education Committee Chair Michael S. Lloyd, MD, FHRS and his guests Miguel A. Leal, MD, FHRS, and Jason T. Jacobson, MD, FHRS, live at HRX 2025. In this prospective series of 12 device-naïve patients (median LVEF ~30%), the authors attempted permanent implantation of a single-coil DF-4 ICD lead into the left bundle branch area (LBBA). They achieved successful implantation with adequate sensing and pacing in 75% of patients, and during short-term follow-up the lead and RV parameters remained stable; minor complications occurred in ~25% of patients (lead micro-dislodgment and septal perforations). The authors conclude that LBBA ICD lead implantation is feasible with current tools and acceptable short-term outcomes, but note the higher-than-expected minor complication rate and emphasize the need for dedicated toolkits, higher operator volume, and a procedural learning curve. Learning Objectives Describe the procedural feasibility, safety considerations, and short-term outcomes associated with left bundle branch area (LBBA) DF-4 defibrillator lead implantation. Identify key technical caveats and patient selection factors relevant to adopting this emerging pacing strategy in clinical practice. Article Information Article Authors Anindya Ghosh, Chenni S.

The Lead Episode 124: A Discussion of Catheter Ablation vs Lifestyle Modification With Antiarrhythmic Drugs to Treat Atrial Fibrillation: PRAGUE 25 Trial, LIVE at HRX 10/30/2025

The Lead Episode 124: A Discussion of Catheter Ablation vs Lifestyle Modification With Antiarrhythmic Drugs to Treat Atrial Fibrillation: PRAGUE 25 Trial, LIVE at HRX Description Join host and Digital Education Committee Member, Danesh Kella, MBBS, FHRS and his guests Ratika Parkash, MD, MS, FHRS and Prashanthan Sanders, MBBS, PhD, FHRS at HRX Live 2025 in Atlanta, for this exciting discussion. The PRAGUE-25 trial, published in JACC in 2025, compared catheter ablation with a program of lifestyle modification plus antiarrhythmic drugs in obese patients (BMI 30–40 kg/m2) with symptomatic atrial fibrillation. At 12 months, freedom from atrial fibrillation was significantly higher with ablation (73%) than with lifestyle modification + AADs (35%), despite the latter group achieving greater weight loss and metabolic improvement. The findings suggest that while aggressive risk-factor control improves overall health, catheter ablation remains more effective for rhythm control in this population. Learning Objectives Describe the comparative effectiveness of catheter ablation versus lifestyle modification with antiarrhythmic drug therapy in obese patients with symptomatic atrial fibrillation. Discuss how weight reduction and risk-factor modification influence atrial fibrillation outcomes, while recognizing that catheter ablation provides superior rhythm control despite metabolic improvements achieved through lifestyle intervention.

The Lead Episode 121: A Discussion of Catheter Ablation or Antiarrhythmic Drugs for Ventricular Tachycardia, LIVE at HRX 10/02/2025

The Lead Episode 121: A Discussion of Catheter Ablation or Antiarrhythmic Drugs for Ventricular Tachycardia, LIVE at HRX Join Digital Education Committee host Jason Jacobson, MD, FHRS, as he discusses this late 2024 article with guests Miguel Valderrabano, MD, PhD, FHRS and J. Peter Weiss, MD, Msci, FHRS, from the HRSTv Studio in Atlanta at HRX 2025. The trial compared two treatment strategies for patients with ventricular tachycardia: early catheter ablation versus continuing antiarrhythmic drug therapy (mostly sotalol or amiodarone). It found that starting with catheter ablation resulted in fewer episodes of ventricular tachycardia, less need for hospitalizations and interventions, and better overall control of arrhythmias compared to relying on drugs alone. Learning Objective: Compare early catheter ablation to continuing antiarrhythmic drug therapy as effective treatment strategies for patients with ventricular tachycardia. Article AuthorsJohn L.
