Ablation of Consecutive Atrial Tachycardia
Ablation of CONseCutive atriaL Tachycardia gUided by Ultra-high-DEnsity Mapping
Source: ClinicalTrials.gov · Last updated 30 Apr 2026
Brief summary (registry, in English)
Ablation of consecutive atrial tachycardia (AT) after ablation of atrial fibrillation (AF) or cardiac surgery can be challenging due to complex substrate and AT mechanisms. A substantial portion of patients is known to show various tachycardias and recurrences occur in a noticeable number of cases. With the availability of novel ultra-high-density mapping techniques characterization and understanding of AT mechanisms and underlying substrate can be improved. Aim of this prospective, multi-center, randomized study is to compare a standard AT ablation approach versus minimalized ablation of the clinical AT in regards to arrhythmia free survival.
