Abstract: Radiofrequency catheter ablation in the treatment of patients with anteroseptal (parahisian) accessory pathways -single center experience Introduction: Preexcitation syndromes are disorders, which essence is the presence of abnormal connection between atria and ventricles -accessory pathway (AP). Localization of AP's is characterized by inter-individual variability. Antero-septal AP's are documented risk factors for complications during radiofrequency catheter ablation (RFCA), and high incidence of recurrences.The aim of the study: To assess the course, success-rate, complications and remote results of RFCA in patients with anteroseptal AP's.Material and methods: Studied population consisted of 11 consecutive, symptomatic patients, in whom during electrophysiologic study (EPS) anteroseptal AP was observed, and subsequently attempts to eliminate the AP by mean of RFCA were undertaken.Localization of AP during EPS (mapping) was being achieved using anatomical, together with electrophysiological criteria, using uni-and bipolar signals obtained from ablation catheter.In order to stabilize the position of ablation electrode and avoid it's dislocation to His-bundle area, we were using stabilization-sheath in each case.To confirm safe location of electrode, programmed stimulation of atrium with the extrastimulus-coupling interval shorter than refractory period of AP was applied.The course, success-rate, complications of RFCA, and recurrences during follow-up were taken into analysis.Results: Total procedure duration equaled 80-220 min (mean ± SD: 154 ± 54 min), fluoroscopy-time -25-90 min (35 ± 22 min), number of RF applications -5-12 (9.5 ± 2.4).Successful RFCA underwent 9 patients (82%), ablation failed in two patients.Symptomatic recurrences were observed in 2 patients (18%).No complications occurred during RFCA.Conclusions: RFCA using described above method is safe and efficient method of treatment in patients with anteroseptal AP's.(
