Key result
Fetal right and left ventricular widths increased significantly from 16 to 38 gestational weeks, while the RV/LV ratio increased from 1.03 to 1.06, a change without clinical significance.

Provides reference nomograms for fetal right and left ventricular widths and their ratio between 16 and 38 weeks of gestation to aid in assessing ventricular disproportion.
Gabbay‐Benziv et al. (2015) conducted an observational in Normal fetal echocardiographic findings (n=1,242). Gestational age was evaluated on Right ventricular (RV) and left ventricular (LV) widths and RV/LV ratio. Fetal right and left ventricular widths increased significantly from 16 to 38 gestational weeks, while the RV/LV ratio increased from 1.03 to 1.06, a change without clinical significance.
