Right ventricular–pulmonary arterial coupling in patients after repair of tetralogy of Fallot

Right ventricular-pulmonary arterial coupling is an important determinant in the development of right ventricular failure. The purpose of our study was to assess right ventricular-pulmonary arterial coupling in children and adolescents with dilatation of the right ventricle after repair of tetralogy of Fallot.Right ventricular-pulmonary arterial coupling was quantified as the ratio of pulmonary arterial elastance (an index of arterial load) and...
