Clinical Trial Summary

Atrial fibrillation (AF) and atrial tachycardia (AT), including type I atrial flutter, are frequently observed in patients with pulmonary hypertension (PH). Catheter ablation of AF / AT has been established as an effective treatment option in selected patients. However, little is known about the efficacy and safety of this approach in patients with PH. It has also been shown that considerable proportion of patients with PH after acutely successful catheter ablation suffer from the recurrence of clinical or newly manifested arrhythmia. We propose a prospective study to compare two ablation strategies in a randomized fashion: radiofrequency catheter ablation targeting only the clinical arrhythmia versus more extensive substrate-based catheter ablation. This project will investigate the clinical outcome of patients with pulmonary hypertension and symptomatic atrial fibrillation / tachycardia who will be randomly allocated to selective versus complex radiofrequency catheter ablation of arrhythmogenic substrate.
