Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to evaluate the effectiveness of Pulmonary Vein Isolation (PVI) performed with the Arctic Front™ Advance Cardiac CryoAblation Catheter System as first-line therapy in comparison with antiarrhythmic drugs (AAD) in patients with paroxysmal atrial fibrillation (AF).

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Subject has been diagnosed with symptomatic paroxysmal atrial fibrillation as defined above and at least two symptomatic episodes in the last six months prior to inclusion.
* At least one episode of AF must be documented during the prior year by any kind of ECG recording.
* Subject has structural normal heart with an LVEF ≥ 50%, thickness of the inter-ventricular septum ≤12 mm and left atrium diameters (short axis) \< 46 mm obtained by transthoracic echocardiography.
* Subject has normal ECG parameters (QRS width in the 12 channel surface ECG ≤120 ms, QTc - interval \< 440 ms, PQ - interval ≤ 210 ms; all parameters should be measured at sinus rhythm).
* Subject is at least 18 and not older than 75years old.
* Subject is able and willing to give informed consent.

Exclusion Criteria

* Subject developed persistent AF at least once in history (electrical or pharmacological cardioversion after 48h or episode duration \>7 days).

* Subject has documented typical atrial flutter.
* Subject has any history of successful or unsuccessful treatment of AF with class I or III antiarrhythmic or sotalol with the intention to prevent an AF recurrence. Patients pretreated with above AAD at maximum 48 hours with the intention to convert an AF episode are allowed.
* Subject had any previous left atrial ablation.
* Subject had any previous cardiac surgery, e.g. prosthetic valves.
* Subject has permanent pacemaker or defibrillator implant.
* Subject has 2° type II, 3° degree AV-block or left/right bundle branch block pattern.
* Subject has unstable angina pectoris.
* Subject has history of previous myocardial infarction or percutaneous intervention during the last three months.
* Subject has symptomatic carotid stenosis.
* Subject has chronic obstructive pulmonary disease with detected pulmonary hypertension or any other evidence of significant lung disease.
* Subject has any contraindication for oral anticoagulation.
* Subject has any history of previous transient ischemic attack or stroke.
* Subject has known intra-cardiac thrombus formation.
* Subject has any significant congenital heart defect corrected or not (except for patent foramen ovale that is allowed).
* Subject has evidence of congestive heart failure (NYHA class II, III or IV) in sinus rhythm.
* Subject has hypertrophic cardiomyopathy.
* Subject has abnormal long or short QT interval, signs of Brugada syndrome, known inheriting ion channel disease on the family, arrhythmogenic right ventricular dysplasia.
* Subject has sarcoidosis.
* Subject has pulmonary vein stent.
* Subject has thrombocytosis (platelet count \> 600,000 / μl) or thrombocytopenia (platelet count \<100,000 / μl).
* Subject has any untreated or uncontrolled hyperthyroidism or hypothyroidism.
* Subject has renal dysfunction with glomerular filtration rate \< 60 ml / min.
* Subject has a reversible causes for AF like hyperthyroidism and alcoholism.
* Subject is a pregnant woman or woman of childbearing potential not on adequate birth control: only woman with a highly effective method of contraception \[oral contraception or intra-uterine device\] (who must have a negative pregnancy test within 1 week of the start of the therapy) or sterile woman can be enrolled.
* Subject is a breastfeeding woman.
* Subject has an active systemic infection.
* Subject is employed by Medtronic or by the department of any of the investigators or is a close relative of any of the investigators.
* Subject is unwilling or unable to comply fully with study procedures and follow-up due to any disease condition, which can raise doubt about compliance and influencing the study outcome especially any kind of cancer, severe bleeding in history or a suspected pro-coagulant state.
* Legal incapacity or evidence that a subject cannot understand the purpose and risks of the study or inability to comply fully with study procedures and follow up.
* Subject has a life expectancy of ≤ 1 year.
* Subject is currently enrolled or planning to participate in a potentially confounding drug or device trial during the course of this study. Co-enrollment in concurrent trials is only allowed when documented pre-approval is obtained from the Medtronic study manager.
