Extraction of lumenless pacing leads from the His bundle and left bundle branch area: outcomes of the high-volume centre
- Single-centre registry study
- EXTRACT Registry
- Department of Electrocardiology in Katowice, Poland
Authors' conclusion
The CSP lead extraction is safe and feasible with a low complication rate and high rate of CSP lead reimplantation.
Study context
- Population
