Mesh Ablator Versus Cryoballoon Pulmonary Vein Ablation of Symptomatic Paroxysmal Atrial Fibrillation (MACPAF)
June 23, 2014 updated by: Jochen B. Fiebach, Charite University, Berlin, Germany
HD Mesh Ablator Versus Cryoballoon Pulmonary Vein Ablation of Symptomatic Paroxysmal Atrial Fibrillation - Efficiency and Safety of PV Ablation Systems
The purpose of this prospective randomized single-center trial is to compare efficiency and safety of two pulmonary vein ablation systems in patients with symptomatic paroxysmal atrial fibrillation using the Arctic Front® versus the HD Mesh Ablator® catheter.

Detailed Description
Primary objective:
• Efficacy of pulmonary vein isolation defined by achieving an exit block for all pulmonary veins per patient.
Secondary objectives:
- Detecting (silent) cerebral thromboembolism using neuro(psychological) tests and brain MRI prior and within 2 days after PV ablation.
- Detecting (silent) cerebral thromboembolism using neuro(psychological) tests and brain MRI within 6 months after PV ablation.
- Determination of spontaneous recurrence rate of atrial fibrillation using a subcutaneously implanted loop recorder (Reveal XT®).
- Characterization of non-neurological major complications (death, atrial-esophageal fistula, pulmonary vein stenosis, pericardial tamponade)
- Rate of iatrogenic interatrial septal defects after transseptal puncture for PV ablation.
