Repeat Ablation Procedure in Patients With Relapse of Atrial Fibrillation

Not Applicable

• Conditions: Ablation; Paroxysmal Atrial Fibrillation
• Interventions: Procedure: Ablation

• Registration Number: NCT01229306
• Lead Sponsor: Deutsches Herzzentrum Muenchen

Brief Summary

Catheter ablation with isolation of the pulmonary veins has proven to be an effective treatment option in patients with paroxysmal atrial fibrillation. In patients who have a relapse of paroxysmal atrial fibrillation after one ablation procedure the investigators compare the reisolation of all pulmonary veins to reisolation plus an anterior left atrial line.

Detailed Description

Catheter ablation with isolation of the pulmonary veins has proven to be an effective treatment option in patients with paroxysmal atrial fibrillation. In patients who have a relapse of paroxysmal atrial fibrillation after one ablation procedure we compare the reisolation of all pulmonary veins to reisolation plus an anterior left atrial line.
