Radiofrequency Ablation

Radiofrequency Catheter ablation is usually undertaken in patients with symptomatic paroxysmal atrial fibrillation that is resistant to at least one antiarrhythmic drug. In patients with either persistent or long-standing persistent atrial fibrillation the treatment strategies and the benefit to risk ratio of catheter ablation are less well established. Extensive and more then one ablation procedure may be necessary in these patients, and it seems reasonable to recommend that they should be refractory to antiarrhythmic drug treatment before ablation or enrolled in a clinical trial. Since amiodarone treatment may be associated serious and frequent adverse effects, especially during long-term use, it is reasonable to consider catheter ablation as an alternative to amiodarone treatment in younger patients with any type of atrial fibrillation.

Ablation and antiarrhythmic drug therapy

The techniques used for ablation of atrial fibrillation in the electrophysiology laboratory depend on the type of atrial fibrillation; paroxysmal, or persistent or permanent. In patients with paroxysmal atrial fibrillation it has been shown that electrical isolation of the 4 pulmonary veins is very effective in eliminating atrial fibrillation with success rates of 70 - 80%.

Radiofrequency ablation

In persistent or permanent atrial fibrillation simply isolating the pulmonary veins is not adequate to prevent recurrence of atrial fibrillation. In addition to pulmonary vein isolation, ablation lines are necessary in several places in the left atrium, along with targeting nests of fractionated electrograms to prevent recurrent atrial fibrillation.
