Aye CYL, et al. – The objectives of this study are to evaluate the feasibility and reproducibility of fetal ventricular measures utilizing 2D echocardiography, report normal ranges in this cohort and compare estimates to other modalities. Current state–of–the–art 2D echocardiography platforms provide accurate, feasible, and reproducible fetal ventricular measures across gestation, and in certain circumstances may be the modality of choice.
