Comparison of fetal cardiac parameters in GDM and controls
Fetal heart rate was similar in GDM and controls. Fetuses of mothers with GDM, compared to controls, had more globular right ventricles (sphericity index 0.7, IQR 0.6 - 0.7 vs 0.6, IQR 0.5 - 0.6, p<0.001) and reduced right and left ventricular systolic function (Table 2), but, there was no significant difference in diastolic functional indices (Table 3).
