Contact Force Guided Ablation Versus Conventional Pulmonary Vein Isolation for Paroxysmal Atrial Fibrillation

Contact Force Guided Ablation Versus Conventional Pulmonary Vein Isolation for Paroxysmal Atrial Fibrillation

The investigators prospectively investigate the differences between contact-force guided pulmonary vein isolation (PVI) and conventional pulmonary vein isolation in patients with paroxysmal atrial fibrillation (PAF) with respect to adenosine guided unmasking of dormant conduction, procedural and clinical outcome.

Inclusion Criteria:

• Patients (>=18 und < 80 years) with symptomatic paroxysmal AF
• At least one unsuccessful attempt of antiarrhythmic drug (betablocker or class I oder III).
• Oral anticoagulation with phenprocoumone, warfarine or DOAKs for at least 4 weeks prior to ablation with weekly documented INR > 2..
• Withdrawal of antiarrhythmic drugs at least 3 half times prior to ablation except amiodarone.

Exclusion Criteria:

• Left atrial thrombus
• Contraindications for oral anticoagulation or adenosin
