Congenital complete atrioventricular block (CCAVB) in premature infants is challenging but manageable. Novel miniaturized pacemakers offer a successful treatment option, improving outcomes for these high-risk neonates.
Area of Science:
- Neonatal cardiology
- Pediatric electrophysiology
- Autoimmune disorders
Background:
- Congenital complete atrioventricular block (CCAVB) is a rare autoimmune disorder with poor prognosis, especially in premature infants with severe bradycardia.
- Advances in neonatal intensive care and pacing technologies have improved survival rates for extremely premature neonates.
Purpose of the Study:
- To present two cases of CCAVB in extremely premature neonates.
- To highlight the successful management of these cases using novel pediatric pacing technologies.
Main Methods:
- Case report of two extremely premature neonates diagnosed with CCAVB.
- Management involved epicardial pacing with a novel miniaturized pacemaker.
Main Results:
- Successful management of both cases with epicardial pacing.
- Demonstrated feasibility and effectiveness of novel miniaturized pacemakers in this population.
Conclusions:
- Epicardial pacing with novel miniaturized pacemakers is a viable and effective strategy for managing CCAVB in extremely premature neonates.
- This approach can significantly reduce morbidity and mortality in this high-risk patient group.
