Pacing in Pediatric Patients with Postoperative Atrioventricular Block

Area of Science:

• Cardiology
• Pediatric Cardiac Surgery
• Electrophysiology

Background:

• Congenital heart disease surgery can disrupt atrioventricular (AV) nodal conduction.
• Postoperative AV block is a potential complication following these procedures.

Purpose of the Study:

• To outline the management and prognosis of AV block after congenital heart disease surgery.
• To define criteria for permanent pacemaker implantation in persistent postoperative AV block.

Main Methods:

• Review of clinical outcomes and pacing requirements in patients with congenital heart disease.
• Analysis of the timing of AV nodal function recovery and indications for intervention.

Main Results:

• Most patients experience early recovery of AV nodal function, requiring only temporary pacing.
• Persistent AV block beyond 7-10 days necessitates permanent pacemaker implantation due to mortality risk.
• A subset of patients may exhibit late recovery of AV nodal function.

Conclusions:

• Early identification and management of AV block are crucial after congenital heart disease surgery.
• Permanent pacing is indicated for persistent AV block to mitigate mortality risks.
• Lifelong pacing therapy is required for patients with unresolved postoperative AV block.
