Abstract:
Objective To explore the relationship between fetal heart size and gestational weeks (GW). Methods The size of left atrium (LA), right atrium (RA), left ventricle (LV), right ventricle (RV), aorta (AO), pulmonary artery (PA), foramen ovale (FO), heart area (HA), thoracic area (TA), heart circumference (HC) and thoracic circumference (TC) were measured for 512 fetal hearts at 14-39 GW. The relationship between GW and the measurement was evaluated. Results The size of fetal heart chambers, AO, PA and ventricular septum (IVS) increased with the development of GW. The PA/AO, LA/RA, LV/RV, HC/TC and HA/TA were stable compared with different GW. Conclusion Fetal heart chambers increase with the development of GW. HA is correlated well with GW.
