Abstract

Brought into clinical practice in 80, method of radiofrequency catheter ablation (RFCA) enabled possibility of causative treatment in patients with preexcitation syndrome. RFCA may be performed utilizing various techniques, choice of one of them depends on experience and preference of the operator. Aim of the study was assessment of efficacy and safety of RFCA targeting accessory pathway's atrial insertion site with help of unipolar signals from ablation-catheter with regard to various localizations of accessory pathways. Material and method studied population consisted of consecutive 149 patients with symptomatic, drug-resistant WPW-syndrome, which were admitted to our Center for electrophysiologic study and RFCA. From the studied population two groups were subdivided: patients with left-sided (group I, n = 112) and right-sided (group II, n = 37) accessory pathway. Every patient underwent electrophysiological study with use of four diagnostic electrodes and after preexcitation was confirmed RFCA was undertaken. In case of left-sided accessory pathway transseptal puncture was performed. Analyzed parameters were: total duration, fluoroscopy-time, number of current-applications during RFCA, as well as success-rate, complications ...Continue Reading
