Key result
Surgical palliation allowed 89% of children with complex cyanotic congenital heart disease to function with moderate exercise limitation, despite reduced exercise tolerance compared with controls.
Why the study?
Does surgical palliation allow children with complex cyanotic congenital heart disease to participate in normal childhood activities and maintain acceptable exercise tolerance?
Observational (n=26)
Does surgical palliation allow children with complex cyanotic congenital heart disease to participate in normal childhood activities and maintain acceptable exercise tolerance?
Palliative surgery allows children with a single functional ventricle to participate in most childhood activities, though formal exercise testing is recommended as subjective estimates of exercise tolerance are often inaccurate.
No takes yet. Share an insight, caveat, or question.
Objective testing needed given frequent parental underestimation; cross-sectional data leaves open prospective validation of activity benefits.
Casey et al. (1994) conducted an observational in Complex cyanotic congenital heart disease (n=26). Surgical palliation vs. Age and sex matched controls was evaluated on Exercise tolerance and activity level. Surgical palliation allowed 89% of children with complex cyanotic congenital heart disease to function with moderate exercise limitation, despite reduced exercise tolerance compared with controls.
