Transvenous extraction of quadripolar coronary sinus pacing leads
Authors' conclusion
Quadripolar CS lead extraction had a high success rate and low rate of major adverse events. Reimplantation in the CS was possible with a good success rate but was often limited by CS branch stenosis or occlusion.
Study context
- Population
- Patients who underwent extraction of coronary sinus (CS) leads between 2013 and 2024102 quadripolar leads and 80 non-quadripolar leads
- Participants
- 182 patients
- Comparison
- Compare outcomes with extraction of non-quadripolar CS leads
- Quadripolar groupn = 102
- Non-quadripolar groupn = 80
- Outcome
- Mean CS lead age
Main finding
As reported in the abstract
P < 0.001
Further findings
Complete procedural success · significantly higher in the quadripolar group
P = 0.01
Complete CS lead removal · no significant difference
P = 0.17
Reimplantation success in the CS · no significant difference
P = 0.30
Extraction techniques
Manual traction alone successful
Laser sheaths used
Rotational cutting tools used
- Complete procedural success: there was no difference between groups after accounting for lead age
Baseline characteristics
- Mean age
- 68.0 ± 11.6 years
- Female
- 22%
Safety
- Major adverse events · directly related to lead extraction — non-quadripolar group
- Two events
