Cryoballoon Pulmonary Vein Isolation for Atrial Fibrillation With Heart Failure (POLAR-HF)
February 3, 2024 updated by: St. Josefs-Hospital Wiesbaden GmbH
The combination of atrial fibrillation (AF) and heart failure (HF) is common and implies a poor prognosis.
Pulmonary vein isolation is an established method for the treatment of symptomatic AF in patients with normal heart function and has been shown to be more effective than drug therapy.
Recently, radiofrequency ablation has shown a positive effect in patients with AF and HF.
POLAR-HF has been designed to investigate efficacy and safety of cryoballoon pulmonary vein isolation in patients with paroxysmal or persistent AF and severe HF (LVEF ≤ 40%).

Other: Heart Failure
Cryoballoon pulmonary vein isolation is a common method for catheter ablation of atrial fibrillation.
Cryoenergy is applied through a balloon in a single-step approach resulting in necrosis by tissue freezing.
