Does velocity vector imaging (VVI) reliably assess regional right ventricular longitudinal functions in healthy fetuses?
Velocity vector imaging is a feasible and reproducible method for assessing fetal right ventricular mechanics, demonstrating that myocardial contractility is established in mid-gestation and remains constant.
Pu et al. (2010) studied this question.
