[Pulmonary vein isolation with multipolar ablation catheters for the treatment of paroxysmal atrial fibrillation]

Abstract

Atrial fibrillation (AFIB) is the most common atrial rhythm disease and is associated with an increased risk of thromboembolic and cardiac complications. Different therapies are used in clinical routine: frequency control with anticoagulants and rhythm control. In patients with paroxysmal AFIB but without structural heart disease, antiarrhythmic drug therapy was previously first priority; however, pulmonary vein catheter ablation is becoming more important. "Single tip" systems, ultrasound, and various balloon techniques have been used in clinical routine. New radiofrequency systems with multipolar radiofrequency ablation catheters, however, give hope for better outcomes with fewer intraprocedural complications, as well as shorter procedure and fluoroscopy times.
