Applications of pacing strategies in neonates and infants

Area of Science:

• Pediatric Cardiology
• Biomedical Engineering

Background:

• Pacing in neonates and infants presents unique challenges including size constraints, growth potential, and the need for lifelong pacing.
• Establishing clear indications for permanent pacing in pediatric patients is hindered by a lack of controlled studies and multicenter data.

Purpose of the Study:

• To review current methods and technological advancements in pacing for neonates and infants.
• To discuss the advantages and disadvantages of different pacing approaches in pediatric populations.

Main Methods:

• Review of temporary pacing methods: transcutaneous, transesophageal, transvenous, and epicardial.
• Comparison of permanent pacemaker implantation approaches: transvenous versus epicardial.
• Discussion of technological innovations in pacemaker generators and leads.

Main Results:

• Temporary pacing effectively restores cardiac output in pediatric patients.
• Epicardial pacing is often preferred over transvenous pacing in neonates and infants due to size, growth, and complication risks (skin erosion, venous thrombosis).
• Technological advances like smaller generators, multiprogrammable features, and steroid-eluting leads enhance safety and efficacy.

Conclusions:

• Pacing in very young patients is advancing, with epicardial approaches showing advantages.
• Current pacing indications for pediatric patients should be considered guidelines due to limited supporting data.
• Further research and data accumulation are needed to refine pacing strategies in neonates and infants.
