Core Tip
Core tip: Heart defects are the most common congenital malformations in fetuses. Fetal cardiac structure and function abnormalities often lead to changes in ventricular volume. Numerous studies have focused on fetal heart functions, which have not been widely accepted. Between October 2014 and September 2015, the intelligent spatiotemporal image correlation technique was used to measure right ventricular volume in 123 normal fetuses and to evaluate right ventricular systolic function to provide a new method for more accurate and convenient evaluation of fetal heart function.
