First paragraph (this article has no abstract)

The cardiac MRI (CMR) pulmonary artery (PA) velocity-area relation (VAR) and pressure-flow relation (PFR) have been shown to change significantly in certain diseases of the PAs in which pulmonary valve function is normal. We hypothesized that the area within the PA VAR changed in concert with stroke work (an index of energy loss, represented by the integrated area of the PFR) in subjects with repaired Tetralogy of Fallot (rTOF) with residual pulmonary valve insufficiency (PI).
