Brief Summary:
This study investigates impact of adenosine versus AF inducibility and subsequent termination on the acute and long-term outcome of paroxysmal AF ablation.

Condition or disease Intervention/treatment Phase
Paroxysmal Atrial Fibrillation Procedure: Adenosine test Procedure: Termination of AF Not Applicable

Detailed Description:

Despite intensive efforts to increase single procedure success rates of pulmonary vein isolation (PVI) for paroxysmal atrial fibrillation (AF), an arrhythmia-free surveillance has not raised beyond 80%. This prospective, randomized study investigates the efficacy of two different procedural endpoints in terms of single-procedure arrhythmia-free outcome.

A total number of 152 patients undergoing de-novo catheter ablation for paroxysmal AF will be randomized to two different treatment arms. In group-A patients, PVI will be performed with the patient either in spontaneous or induced AF. If AF will not terminate with PVI, ablation will be continued by targeting extra-PV AF sources with the desired endpoint of termination to sinus rhythm (SR). The ablation procedure in group-B patients consists of PVI exclusively, regardless to the underlying rhythm. In this group, all isolated PVs will be challenged to adenosine administration in the attempt to reveal and ablate dormant conduction. The primary endpoint is arrhythmia-free survival during a follow-up of 1 year.

Adenosine testing after PVI and elimination of dormant conduction
Procedure: Adenosine test
Testing dormant conduction after PVI

Active Comparator: Group B - Termination of AF
Termination of atrial fibrillation by catheter ablation
Procedure: Termination of AF

Primary Outcome Measures :
  1. Arrhythmia-free survival [ Time Frame: 1 year ]
    arrhythmia-free outcome during 1 year after the procedure

Secondary Outcome Measures :
  1. Recurrence if PV conduction after ablation in PVs with abolished dormant conduction [ Time Frame: 1 year ]
    PV conduction recurrences after elimination of dormant conduction. This endpoint will be evaluated during repeat procedures for recurrences of atrial fibrillation or atrial tachycardia.
