Congenital complete atrio-ventricular block (CAVB) generally has a good prognosis, though some patients may develop dilated cardiomyopathy. Most patients with CAVB require a pacemaker, often implanted later in life.

Area of Science:

  • Cardiology
  • Pediatric Cardiology
  • Electrophysiology

Context:

  • Congenital complete atrio-ventricular block (CAVB) is a rare condition.
  • Long-term outcomes and surveillance methods for isolated CAVB are not well-defined.

Purpose:

  • To investigate the long-term evolution of isolated CAVB in a retrospective series of 54 patients.
  • To evaluate the effectiveness of different surveillance methods for CAVB.

Summary:

  • This study followed 54 patients with isolated CAVB for an average of 14.5 years.
  • Pacemakers were implanted in 76% of patients, with implantation age varying based on diagnosis age.
  • While prognosis is generally good, rare cases of dilated cardiomyopathy occurred despite pacemaker use.

Impact:

  • This research highlights the generally favorable long-term outlook for isolated CAVB.
  • It underscores the need for continued monitoring due to the potential for rare but severe complications like dilated cardiomyopathy.
  • Findings inform clinical surveillance strategies and pacemaker implantation decisions in CAVB patients.
