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

## TL;DR

This paper presents a case where radiofrequency ablation was performed without fluoroscopy to treat two heart rhythm disorders using imaging and 3D mapping.

## Contribution

The novelty is the first single-stage zero-fluoroscopy ablation for both AF and epicardial VT using ICE and 3D mapping.

## Key findings

- Zero-fluoroscopy ablation successfully treated both AF and epicardial VT in a single procedure.
- Intracardiac echocardiography and 3D mapping ensured precision and safety without fluoroscopy.
- The approach reduced radiation exposure while achieving symptom relief and sinus rhythm restoration.

## Abstract

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.

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.

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.

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