| Abstract |
|
Exercise tolerance tests were performed using treadmill in 21 patients with tetralogy of Fallot (TOF) repaired earlier (4.8 years in mean) and 10 subjects with small ventricular septal defect or normal heart, aged 8-16 years. Pre and postexercise echocardiography and cardiac catheterization were also performed and the hemodynamic data were compared with exercise parameters. The following results were obtained. 1) The patients with right ventricular systolic pressure (RVP) above 100 mmHg have severe exercise intolerance compared with patients with RVP less than 100 mmHg and the control subjects. 2) The degree of posteoperative pulmonary regurgitation did not influence the exercise tolerance. 3) Echoardiographic interventricular septal configuration can be a godd predictor for exercise tolerance. |
