RTOF = repaired tetralogy of Fallot. LV and RV = left and right ventricles. CO = cardiac output measure on cine function sequences. ESV = end systolic volume. EDV = end diastolic volume. Sv = Stroke volume. EF = ejection fraction. AC = aortic compliance. AD = aortic distensibility. i = index. AAo = ascending aorta. DAO = descending aorta. All measures are indexed.
†: CO measured with flow sequence, to avoid false value of CO induced by the pulmonary regurgitation fraction.
* Significance level of differences obtained between exercise and rest was p<0.05.
