Figures & data
Figure 1. Flow chart of the study. VSD: ventricular septal defect.
Figure 2. The diastolic and systolic diameters of left and right ventricleswere measured by M-mode echocardiography and FS were calculated. A is a 25-weeks normalfetus and B is a 25-weeks fetus in a pregnant woman with hypothyroidism. The RV FS of Bfetus was lower than that of A fetus.
Figure 3. Schematic diagram of calculating Tei index. The time (a) between the end of mitral A wave to the beginning of E wave in the next cardiac cycle, and the duration (b) of aortic ejection were measured after the Doppler spectra of LV inflow and outflowtract were obtained. Tei index = (a–b)/b. LVOT: Left ventricular outflow tract.
