Ablation of Ventricular Fibrillation by Accurate Targeting of Arrhythmogenic Regions (AVATAR) — AVATAR  

Ventricular Tachyarrhythmias Clinical Trial

Official title: Ablation of Ventricular Fibrillation by Accurate Targeting of Arrhythmogenic Regions (AVATAR)

Status Completed

Clinical Trial Summary

This study will test the hypothesis that many human heart rhythm disorders are caused by small localized sources, where brief ablation may successfully eliminate the heart rhythm disorder.

Clinical Trial Description

The investigators will enroll patients with documented rapid heart rates from the bottom chambers of the heart (ventricular tachyarrhythmias).

During electrophysiological study, the investigators will map the localized sources of these heart rhythm disorders.

1. The 'active' group will prospectively receive brief ablation at localized sources (Focal Impulse and Rotor Modulation, FIRM).

2. The control group will be a historical cohort who have received traditional ablation for this disorder.

All patients will be followed for up to 1 year to ensure that they have no recurrent arrhythmias. ;
