Cardiac Ablation Clinical Trials

This pilot study investigates if non-invasive global mapping can guide catheter ablation of atrial fibrillation (AF) by defining personalized targets based on the temporal Stability of local Atrial High-Rate Activity (SAHRA). The study also assesses efficacy and safety of this approach and evaluates potential signals of harm. The main questions it aims to answer are: * Does ablation of targets defined by non-invasive global mapping improve rates of acute atrial fibrillation termination? * Does such a personalized ablation approach reduce arrhythmia recurrence rates? Researchers will compare the results of the personalized ablation approach with comparable patients that had undergone a conventional empirical ablation approach (pulmonary vein isolation). Participants will: * Undergo a personalized catheter ablation approach employing both a non-invasive global mapping system and a conventional intracardiac mapping system * Visit the clinic 3, 6 and 12 months after ablation for clinical follow-up * Schedule a telephone visit 9 and 24 months after ablation for clinical follow-up
