Strain may flag early RV dysfunction in repaired TOF; leaves open whether it predicts outcomes or guides PVR timing.
In asymptomatic children after tetralogy of Fallot repair, pulmonary regurgitation correlates with impaired regional systolic right ventricular deformation indices, suggesting strain and strain rate may serve as early indicators of right ventricular dysfunction.
Eyskens et al. (2010) studied this question.
