Treadmill Test in Children after Cardiac Surgery: Comparison to Cardiac Catheterization Data

There have been a number of reports on treadmill exercise (TM) testing for the postoperative evaluation of patients with congenital heart disease. However, the significance of the parameters observed during TM testing, in terms of their correlation with cardiac performance, has not been elucidated. The purpose of this study was to evaluate the validity of TM testing in assessment of the exercise capacity in postoperative patients, by comparing the findings of TM testing to the parameters of cardiac performance obtained by cardiac catheterization.
