Measurement of cognitive outcome and quality of life in congenital heart disease

ince the 1970s, the improvement of diagnostic tools and the success of cardiac surgery have dramatically changed the natural history of complex congenital heart diseases. The number of newborns who have survived through infancy, reaching adolescence and adult age, and becoming socially integrated has increased. 1 2 Consequently, nowadays determinants of late surgical results are evaluated by not only using survival as a measure, which was of major importance for surgeons and cardiologists up until the 1980s, but also by freedom from negative clinical events together with improvements in quality of life. Various guidelines, 3 based on long post-surgical follow-up and knowledge of sequelae and complications, codify clinical evaluation of adult patients with a congenital heart defect. It is more difficult to codify the assessment of cognitive performance and quality of life.
