Key result
Children who underwent surgical repair for simple congenital heart defects achieved normal maximal exercise performance (2.8 W/kg), whereas those with complex defects had significantly impaired capacity.
Why the study?
Does surgical repair of congenital heart defects in infancy restore normal exercise capacity in school-aged children compared to healthy peers?
Population
84 children aged 4 to 11 years who underwent surgical repair for congenital heart defects in infancy.
Comparison
Surgical repair of congenital heart defects in… vs 98 sex- and age-matched healthy children.

Exercise capacity may remain reduced after infant congenital heart surgery; leaves open whether interventions can normalize fitness by school age.

Does surgical repair of congenital heart defects in infancy restore normal exercise capacity in school-aged children compared to healthy peers?
Surgical correction of simple congenital heart defects restores normal exercise capacity in childhood, whereas children with complex defects continue to experience significantly impaired exercise performance.
Norozi et al. (2005) conducted a case-control in Congenital heart defects (n=182). Surgical repair of congenital heart defects vs. Healthy children was evaluated on Normalized maximal performance on bicycle ergometer. Children who underwent surgical repair for simple congenital heart defects achieved normal maximal exercise performance (2.8 W/kg), whereas those with complex defects had significantly impaired capacity.
