Reference values for variables of fetal cardiocirculatory dynamics at 11-14 weeks of gestation.
Despite the increasing popularity of first-trimester fetal echocardiography, the evaluation of fetal heart function during this period remains challenging. The parameters of normal cardiac function at 11-14 weeks' gestation are not well defined and appropriate reference values have not yet been established. The purpose of this study was to evaluate the fetal cardiocirculatory dynamics during routine first-trimester screening and establish cross-sectional reference ranges for 11-14 weeks' gestation. ⋯ We have established reference ranges for the noninvasive evaluation of fetal cardiocirculatory dynamics at 11-14 weeks' gestation.

Color Doppler twinkling artifact in fetuses with echogenic intracardiac foci: echocardiographic observation and clinical significance.
To evaluate echocardiographic characteristics and clinical relevance of color Doppler twinkling artifacts in fetuses with isolated echogenic intracardiac foci (EIF). ⋯ Color Doppler twinkling artifacts from isolated EIF occur in some fetuses and may be considered as an additional echocardiographic feature of EIF. Attention should be paid to the identification and interpretation of these artifacts so that they may be accurately distinguished from true color flow generated by atrioventricular valvular regurgitation jets.
