Epicardial pacing outcomes in infants with heart block: Lead and device complications from a multicenter experience
Authors' conclusion
Device complications affect 15% of infants receiving a permanent PM for heart block. Age ≤90 days at PM implantation is especially associated with infectious complications. Epicardial lead durability appears similar to previously reported pediatric experiences.
Study context
- Population
- Infants with complete heart block receiving an epicardial pacemaker, 2000–2021282 bipolar, 39 unipolar leads
- Participants
- 174 infants
- Outcome
- Time to device-related adverse event:
- Lead failure requiring revision
- Pocket infection
- Exit block requiring increased pacing output
- Lead-related coronary artery compression
