Melissa E. Middeldorp, MPH, PhD, University of Adelaide is joined by Jenelle Dziano, Centre for Heart Rhythm Disorders, The University of Adelaide and Jared Bunch, MD, FHRS, University of Utah School of Medicine, to discuss a study that investigated the relationship between atrial fibrillation (AF), brain glymphatic function, and cognitive performance. Using MRI-derived diffusion tensor imaging along the perivascular space (DTI-ALPS), the authors found that patients with AF especially those with no paroxysmal AF exhibited impaired glymphatic activity compared to healthy controls. This reduced...

William H. Sauer, MD, FHRS, Brigham and Women's Hospital is joined by Wendy S. Tzou, MD, FHRS, University of Colorado Anschutz Medical Campus and Kishan Padalia, MD, University of Colorado, to discuss the results of ablation of sustained monomorphic ventricular tachycardia (SMVT) are suboptimal. For many patients with implantable cardioverter-defibrillators (ICDs), ICD electrograms (ICD-EGs) provide the only available information on SMVT. ICD-EGs have the ability to distinguish morphologically distinct SMVT and can be used for pace mapping. https://www.hrsonline.org/education/TheLead...

Deep Chandh Raja, MBBS, MD, PhD, Australian National University, Kauvery Hospital is joined by Andreas Pflaumer, MD, FHRS, CEPS-P, Royal Children's Hospital Melbourne and Maully J. Shah, MBBS, FHRS, CCDS, CEPS-P Children's Hospital of Philadelphia, to discuss the unmet clinical need for a smaller pacemaker suitable for neonates and infants, researchers developed a specially modified implantable pulse generator incorporating a Medtronic Micra subassembly within a polymer header, connected to a bipolar epicardial lead. This study aimed to evaluate the safety, feasibility, and midterm outcomes of...

Melissa E. Middeldorp, MPH, PhD is joined by Martin K. Stiles, MBChB, PhD, FHRS, University of Auckland and Waikato Hospital and Eloi Marijon, MD, PhD, Paris University & European Georges Pompidou Hospital, to discuss this Danish nationwide study examines the relationship between socioeconomic position (SEP) and sudden cardiac death (SCD) as well as all-cause mortality (ACM). Analyzing all deaths in Denmark from 2010, researchers found a strong inverse association between both income and education level and the risk of SCD and ACM. Individuals in the lowest income and education groups had...

Please join host Michael S. Lloyd, MD, FHRS at HRS 2025 in San Diego as he discusses this article with Stephanie Wang, MD and Emily Zeitler, MD. The study investigated whether PFA-induced coronary spasms during ablation could cause lasting changes—such as mild lumen narrowing—at the ablation site over a three-month period. https://www.hrsonline.org/education/TheLead https://www.jacc.org/doi/10.1016/j.jacep.2025.03.014 Host Disclosure(s): M.

Please join host Jason T. Jacobson, MD, FHRS at HRS 2025 in San Diego as he discusses this article with Marmar Vaseghi, MD, MS, PhD, FHRS and Mayank Sardana, MBBS, MS. The prospective, multicenter, randomized BRAVE trial evaluated epicardial catheter ablation targeting the arrhythmogenic substrate in Brugada syndrome patients with implantable cardioverter-defibrillators (ICDs) to prevent ventricular fibrillation (VF). After a planned interim analysis of 52 patients, ablation significantly reduced VF episodes compared with controls (hazard ratio 0.29; P = .018), prompting early trial...

This late-breaking randomized trial, published online on April 26, 2025 in Heart Rhythm, demonstrated that using CT scan guidance for ventricular tachycardia (VT) ablation significantly shortens procedure time while maintaining a safety profile comparable to conventional methods. In essence, CT-guided ablation offers a faster, equally safe alternative for VT treatment. A discussion of the late breakers was recorded live in San Diego at Heart Rhythm 2025. https://www.hrsonline.org/education/TheLead https://www.heartrhythmjournal.com/article/S1547-5271(25)02182-4/fulltext Host Disclosure(s): ...

Left Bundle Area Pacing in Hypertrophied Hearts: An Ex Vivo Ovine Model to Study Deployment of Pacing Leads in Thick Septum describes the development of a novel ex vivo sheep heart model with induced septal hypertrophy to simulate challenging left bundle branch area pacing (LBBAP) scenarios. The study evaluates the deployment characteristics and fixation behavior of pacing leads in thickened septal tissue, aiming to improve procedural safety and lead placement strategies in patients with left ventricular hypertrophy. This model offers a valuable tool for preclinical testing and refinement of...

Join us at Heart Rhythm 2025 for the discussion of this study. Between July 2014 and June 2023, researchers tracked 641 sudden cardiac arrest (SCA) incidents in U.S. athletes aged 11–29. Overall survival was 49%, rising to 57% during exercise, and reaching 70% in game/competition settings compared to 53% during practice. Survival rates improved significantly over the nine years, yet notable racial disparities persisted: Black athletes were 37% less likely, and athletes of other non-White races 31% less likely, to survive exertional SCAs than White athletes. The authors emphasize that while...
info_outlineThis global, multicenter registry included 2,579 CRT recipients with LVEF ≤ 50% who underwent either LBBAP or conventional biventricular pacing (BVP), with 780 matched pairs analyzed. Over a mean follow-up of 34 ± 15 months, LBBAP significantly reduced the combined endpoint of all-cause death or first heart failure hospitalization (22.2% vs 30.8%; HR 0.81; P≈0.048), largely driven by fewer HF hospitalizations (13.6% vs 20.8%; HR 0.63; P<0.001). Patients in the LBBAP arm also experienced shorter paced QRS duration (129 vs 143 ms) and fewer procedural complications (3.5% vs 6.5%; P=0.004). Mortality rates were similar between groups, reinforcing LBBAP's safety and potential efficacy for CRT in this patient population.
Join host Michael S. Lloyd, MD, FHRS and guests Hakeem Ayinde, MD, FHRS, and Prashant Bhave, MD, FHRS for this discussion, recorded at Heart Rhythm 2025 in San Diego, California.
