V max may augment standard hemodynamic assessment in children with heart lesions; leaves open need for prospective validation before routine adoption.
Does measurement of maximal contractile element velocity (V max) improve the evaluation of myocardial function compared to usual hemodynamic criteria in children and young people with heart lesions?
Measurement of V max provides an additional index of myocardial state that can detect abnormalities missed by routine catheterization data.
Hugenholtz et al. (1970) studied this question.
