Overview

Retrospective cohort shows increased arrhythmia prevalence in lateral tunnel over extra-cardiac Fontan patients, suggesting implications for risk assessment.

Key Points

  • Arrhythmia was present in 52.2% of patients, including 57.9% in the lateral tunnel group.
  • Logistic regression indicated that patients with lateral tunnel Fontan had a higher odds ratio of 1.84 for developing arrhythmias.
  • The study utilized a retrospective cohort approach with analysis from a single adult congenital heart disease center.
  • Results highlight the need for targeted screening protocols for patients with lateral tunnel Fontan circulations.
