Zero Fluoroscopy Radiofrequency Ablation of Paroxysmal Atrial Fibrillation and Epicardial Ventricular Tachycardia.

BACKGROUND

Paroxysmal atrial fibrillation (AF) and epicardial ventricular tachycardia (VT) are complex arrhythmias requiring precise, safe ablation. Zero-fluoroscopy radiofrequency ablation (RFA) minimizes radiation exposure while maintaining procedural accuracy.

FIH/EARLY REPORTS SUMMARY: A 56-year-old male with diabetes, hypertrophic cardiomyopathy, AF, and VT underwent zero-fluoroscopy, single-stage RFA for both AF and epicardial VT. Integration of intracardiac echocardiography (ICE) and CARTO 3D mapping enabled effective ablation and restored sinus rhythm with symptom relief.

DISCUSSION: This case highlights the utility of ICE and CARTO 3D in enhancing procedural precision and safety. Eliminating fluoroscopy reduces radiation risks, particularly in complex cases.

NOVELTY: This is the first report of single-stage, zero-fluoroscopy RFA for both AF and epicardial VT using ICE and 3D mapping.
