[Catheter ablation for therapy of patients with arrhythmia].
Catheter ablation using radiofrequency currents has been established as the safe and effective therapeutic modality of tachyarrhythmias. Most stable results were obtained in the ablation of accessory pathway of any location in WPW syndrome, and in the ablation of slow pathway in atrioventricular nodal reentry. However, in ventricular tachycardia, the efficacy is strongly affected by underlying heart diseases as well as the site of VT origin. Idiopathic VT either from the right ventricular outflow tract or left ventricular septum can be highly ablated. Common type atrial flutter is another candidate for catheter ablation. Using catheter, Maze procedure is mimicked in atrial fibrillation.
