EP Edge Journal Watch Issue 18 (April 2026): AF Cancer Signals, PFA Recalibration, EMBOL-AF, SMART-ALERT, LBBAP, and VT Rescue

In EP Edge™ Journal Watch Issue 19 (April 2026), Dr. Niraj Sharma takes a high-level look at the latest developments in cardiac electrophysiology, with a sharp focus on atrial fibrillation, pulsed field ablation, embolic risk, physiologic pacing, and ventricular arrhythmia rescue strategies.This episode moves beyond routine rhythm-control discussions and examines whether new-onset atrial fibrillation may serve as a marker of incident cancer, why the traditional 90-day blanking period after AF ablation may need reassessment in the era of pulsed field ablation (PFA), and what the BEAT PAROX-AF trial actually showed when PFA was tested head-to-head against optimized radiofrequency ablation. The episode also reviews whether posterior wall isolation adds value during redo AF ablation, and analyzes the EMBOL-AF Global Registry, which offers one of the most important contemporary looks at stroke and systemic embolism after atrial fibrillation ablation. Additional discussions include a selective approach to left atrial thrombus imaging before ablation, the SMART-ALERT study on real-time smartphone notifications for AF episodes, long-term outcome data comparing left bundle branch area pacing with right ventricular pacing in atrioventricular block, novel ambulatory precursors of ventricular fibrillation, and an intriguing small series exploring conduction system pacing as an alternative or bridging strategy in drug-refractory ventricular tachycardia. This podcast is designed for electrophysiologists, cardiologists, fellows, advanced practice providers, researchers, and the broader EP community looking for concise but rigorous analysis of the most clinically meaningful new studies in arrhythmia care. Expect expert discussion of AF ablation, PFA trials, stroke prevention, left bundle branch pacing, ventricular tachycardia, and the evolving science shaping modern EP practice. All references and details are available on the LinkedIn newsletter as well as on Substack, epedge.substack.com.
