Implication

May signal residual conduction damage and late recurrence risk after transient block in RBBB+LAD; hypothesis-generating, needs prospective confirmation.

Structured PICO

P
Population
22 postoperative pediatric patients (repair of ventricular septal defect and tetralogy of Fallot), including 5 who developed late complete heart block 5 months to 5 years after surgery and 17 additional postoperative patients in sinus rhythm.
I
Intervention
His bundle electrogram recording
O
Outcome
Site of conduction block and H-V interval prolongationsurrogate

Postoperative congenital heart disease patients with an ECG pattern of RBBB and LAD who had transient complete heart block postoperatively may have extensive residual conduction system damage and are at risk for late recurrence of complete heart block.
