Abstract
Introduction Restrictive physiology of the right ventricle(RV) has been associated with a better long-term prognosis in patients afterTetralogy of Fallot(TOF) repair presumably because the decreased compliance prevents dilation of RV. However, there is another report that restrictive physiology is related to poor exercise tolerance. The presence of end diastolic forward flow(EDFF) in the pulmonary artery in patients with pulmonary regurgitation is commonly used to diagnose restriction of the RV.

We evaluated the timing of flow patterns of the ascending aorta and pulmonary artery, mitral and tricuspid inflow, obtained by phase contrast magnetic resonance imaging (MRI)
Summary
Restrictive physiology of the right ventricle(RV) has been associated with a better long-term prognosis in patients afterTetralogy of Fallot(TOF) repair presumably because the decreased compliance prevents dilation of RV. There is another report that restrictive physiology is related to poor exercise tolerance. The presence of end diastolic forward flow(EDFF) in the pulmonary artery in patients with pulmonary regurgitation is commonly used to diagnose "restriction" of the RV. Prevalence and clinical significance of EDFF to prognosis of the in patients with repaired TOF
