Background: The aim of this study was to test the hypotheses that (1) fetuses with complete transposition of the great arteries (D-TGA) and Taussig-Bing anomaly (TBA) has decreased the left ventricular (LV) and right ventricular(RV) mechanical function compared with normal fetuses, and (2)the decreased myocardial mechanical function in fetal D-TGA and TBA was associated with the degree of transposition of the great arteries, pulmonary stenosis(PS) and ventricular septal defect(VSD). Methods: We retrospectively identified 49 cases of fetal D-TGA and 29 cases of fetal TBA and compared findings to 49 controls of comparable gestational age. Postprocessing analysis of the left ventricle and right ventricle were done using syngo Velocity Vector Imaging version 2.3. Global and regional longitudinal systolic peak velocity, strain and strain rate were generated. Results: (1) Comparing with control group, the global and regional longitudinal systolic peak velocity (GLV), strain (GLS) and strain rate (GLSR) of the LV and RV were decreased in the group of D-TGA and TBA (P<0.05). (2) In the group of D-TGA and TBA, the multivariate linear regression analysis, the VSD was the independent determinant of LVGLS and RVGLS (β = 0.270, P=0.014 and β = 0.465, P< 0.001). The PS was the independent determinant of RVGLSR (β = 0.090, P=0.009). Conclusion: The ventricular function of fetal D-TGA and TBA were decreased compared with control group. The PS and VSD were the independent determinant factors of the decreased LVGLS, RVGLS and RVGLSR in the fetal D-TGA and TBA.
