Atrial Fibrillation Ablation in Patients with Pulmonary Hypertension: Multicenter Experience

Pulmonary hypertension (PH) is a progressive condition characterized by pulmonary vascular remodeling and elevated pulmonary arterial pressure. Atrial arrhythmias are common in PH and may contribute to right ventricular failure and death1,2. We retrospectively identified patients with pre-capillary PH who underwent catheter ablation for AF at four high-volume ablation centers. Included patients had an established clinical diagnosis of PH, with suspected pre-capillary etiology, and at least one right heart catheterization showing mean pulmonary artery pressure>20 mm Hg and pulmonary capillary wedge pressure ≤15 mm Hg.
