Insights

Surgical closure of atrial septal defect in childhood offers good long-term survival up to 50 years, comparable to the general population. While re-intervention rates are low, supraventricular tachycardia is common.

Area of Science:

  • Cardiology
  • Pediatric Cardiology
  • Adult Congenital Heart Disease

Background:

  • Atrial septal defect (ASD) closure in childhood is a common procedure.
  • Long-term outcomes and quality of life after early surgical intervention require comprehensive evaluation.

Purpose of the Study:

  • To assess the clinical outcomes and quality of life up to 50 years post-surgical closure of atrial septal defect (ASD) in childhood.
  • To evaluate major adverse cardiac events (MACE) including mortality, re-interventions, stroke, heart failure, and arrhythmias.

Main Methods:

  • A single-center, longitudinal cohort study included 135 patients who underwent surgical ASD closure before age 15 (1968-1980).
  • Participants underwent extensive cardiac evaluations and quality-of-life assessments every 10 years.
  • Follow-up extended up to 50 years post-surgery.

Main Results:

  • 86% survival at 50 years, comparable to the general Dutch population.
  • 59% event-free survival at 45 years and 46% at 50 years; common events included symptomatic arrhythmia (25%) and pacemaker implantation (10%).
  • Normal exercise capacity (77%), no pulmonary hypertension, but diminished right ventricular ejection fraction in 6% and elevated NT-proBNP in 61%.

Conclusions:

  • Surgical ASD closure in childhood leads to good long-term survival, with outcomes comparable to the general population at 50 years.
  • Low re-intervention rates and absence of pulmonary hypertension are favorable.
  • Good exercise capacity and quality of life are maintained, but supraventricular tachycardia is a frequent long-term complication.
