Long-term performance of domestic active-fixation endocardial pacing leads

Aim. The aim of the study was to evaluate long-term results implantation domestic endocardial leads (EL) with active fixation ELBI 233C-53 and 233C-58, implanted in atrial ventricular positions, respectively. Methods. A total 165 patients were included retrospective, single-center study. 239 EL from 2016 2018 (55 184 233C-58). median age 78 years (43 92 years). 846 programming protocols analyzed, which carried out on 1st day after implantation, then every 6 months. Complications are divided into early (1-7 days) late (8 days or more). Results. In group, there no statistically significant changes pacing parameters during observation period. There complications (10.9%): exit block (n=1, 1.8%), dislocation (n=3, 5.4%), damage structure (n=2, 3.7%). number reoperations 3 (5.4%). 233C-58 a increase threshold found (p=0.026). 13 (7.0%) registered, including an (n=11.6%), 0.5%), 0.5%). this group 2 (1%). Conclusion. demonstrated acceptable safety observation. occurred mainly first year implantation. repeated operations low. deaths caused by lead
