[Atrial fibrillation -- interventional therapy with respect to age].

Actual therapy of atrial fibrillation follows either the rate or rhythm control strategy. To stabilize sinus rhythm after cardioversion or in case of paroxysmal atrial fibrillation, medical treatment is currently first line therapy. In patients who develop drug-refractory atrial fibrillation, further invasive treatment modalities like preventive pacing, hybrid therapy or catheter-based ablation techniques including pulmonary vein ablation or linear atrial lesion are available. However, interventional atrial fibrillation therapy should be reserved for the highly symptomatic patient due to its limited efficacy and risk of complication. Due to the higher relevance of the AF substrate in elderly patients, ablation therapy will be of limited use until substrate modification in addition to trigger elimination will reach an established stage as a clinical procedure. Hybrid therapy however, with ablation of the cavotricuspid isthmus is as suitable in elderly patients as in the young or middle-aged.
