Superior RA site for atrial leadless PM feasible and better preserves intrinsic activation vs RAA base. #LeadlessPacing

TWOSOME: Single-shot PFA faster procedure (44 vs 119 min) but longer fluoro. 12-mo freedom ~76-82% both. #PFA #AFib

EGM-guided PFA for PerAF: 82.4% 12-mo AF/AT-free vs 65.9% with PWI-only. Higher success when procedure terminated AF. #PFA #PersistentAF

New short communication on chronic retrieval of atrial leadless pacemakers from US IDE patients. Practical data as the technology expands. #LeadlessPacing #EP

Porcine data: Local ethanol irrigation after submaximal PFA increased acute and 7-day lesion dimensions vs saline. Ethanol alone created no lesions. Potential adjuvant concept for PFA. #PFA #EP

November Heart Rhythm is out. Strong focus on the PFA transition: energy source shifts, adjunctive lesion sets, and real-world adverse event analyses. #PFA #AFib

Roman 4 study (Heart Rhythm): No clear acute evidence of increased ventricular arrhythmogenicity after cardioneuroablation in patients without structural heart disease. VT induced only in 2 pts with prior conditions. #Cardioneuroablation #EP

New Heart Rhythm data (364 HCM pts): PFA associated with lower 24-mo AF recurrence vs RF (adj HR 0.57). Lowest complication rate among modalities. #PFA #AFib #HCM

Atrial fibrillation (AFib) is the most common serious heart rhythm problem. The heart's upper chambers beat fast & irregularly instead of in a steady rhythm. About 1 in 3 people develop it in their lifetime. It's treatable—and knowing the signs matters. 🫀 #AFib
