Abstract
Background. Navigation systems can perform anatomical reconstruction of the heart, build activation maps and perform accurate radiofrequency ablation (RFA). But they are ineffective because of the anatomical location of the arrhythmogenic focus. The method of surface non-invasive mapping, allows you to determine the prognosis, evaluate the scope and treatment tactics.
The goal is to assess the accuracy and effectiveness of eliminating surface and invasive endocardial mapping using the Russian systems «Amycard» and «Astrocard».
Material and methods. The study included 23 patients (m – 16, f – 7) with ventricular rhythm disturbances of non-ischemic origin. Patients underwent non-invasive pre-operative mapping using the «Amycard» system and invasive mapping using the «Astrocard» complex and subsequent RFA.
Results. In 22 patients, the early activity zone was verified from the endocardial ventricular surface, with the epicardial surface in 1 case. Efficiency RFA was 82,6% (19). The accuracy of the coincidence of noninvasive and endocardial invasive mapping was 98%.
Conclusion. Use of non-invasive preoperative mapping makes possible to accurately verify the arrhythmogenic focus in the heart, as evidenced by the results of invasive mapping. It increases the effectiveness of RFA, reduces the duration of the procedure and fluoroscopy, and determines the tactics of treatment.
