Güneydoğu Anadolu Bölgesindeki Atriyoventriküler Reentran Taşikardilerdeki Aksesuar Yolların Dağılımı

Abstract

Objective: We aimed to evaluate distribution of accessory pathway (AP) in atrioventricular reentrant tachycardia (AVRT) in southeast Anatolian region of Turkey. Methods: The study was a retrospective cross-sectional design. Consecutive patients who underwent catheter ablation of AVRT between June 2012 and July 2014 were included in the study. All patients were taken to the electrophysiology laboratory in the nonsedated state and underwent an initial diagnostic study using three diagnostic catheters. The one of them was placed in coronary sinus. In those patients, in whom the AP was identified, ablation therapy was carried out using radiofrequency energy. We decided distribution of AP on fluoroscopy. Fluoroscopic images are obtained in and the left anterior oblique orientation. Results:The study population consisted of 64 AVRT patients (63% female; mean age 34±14). Among AVRT 20(31%) patients had concealed AVRT, 44 (69%) patients had Wolf Parkinson White syndrome. Distribution of AP was 59% at the left free wall, 34% at the posteroseptum, 6% at the right free wall, and 3% at the anteroseptum. The locations of APs were compared. There was no any statistically significant among groups. Conclusion: Distribution of AP location was in accordance with literature. The other characteristic of AVRT were similar with the current data.
