Conditions

Ablation, Paroxysmal Atrial Fibrillation

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.
