Diagnostic value of echocardiography in fetal cardiac malformation and clinical classification was investigated. In total, 206 high-risk parturients, who received a screening of prenatal fetal cardiac malformation in Jinan Maternity and Child Care Hospital from January 2015 to June 2017, were retrospectively analyzed, among those parturients, the results of labor induction or newborns of 141 parturients were diagnosed as cardiac malformation, the fetuses of 65 parturients were diagnosed as non-cardiac malformation, the detection of fetal cardiac malformation of all the parturients was carried out by two-dimensional ultrasound and four-dimensional ultrasound during gestation period, presence or absence of congenital cardiac malformation of the fetuses and clinical classification were estimated. The sensitivity of two-dimensional ultrasound diagnosis combined with four-dimensional ultrasound diagnosis was significantly higher than that of two-dimensional ultrasound diagnosis and four-dimensional ultrasound diagnosis (P<0.05). In addition, the sensitivity of four-dimensional ultrasound diagnosis was significantly higher than that of two-dimensional ultrasound diagnosis (P<0.05). The specificity and positive predictive value of four-dimensional ultrasound diagnosis were significantly higher than those of two-dimensional ultrasound diagnosis and two-dimensional ultrasound diagnosis combined with four-dimensional ultrasound diagnosis (P<0.05). The diagnostic coincidence rates of four-dimensional ultrasound diagnosis and two-dimensional ultrasound diagnosis combined with four-dimensional ultrasound diagnosis were significantly higher than that of two-dimensional ultrasound diagnosis (P<0.05). The negative predictive values of the combined ultrasound diagnosis and four-dimensional ultrasound diagnosis were significantly higher than that of two-dimensional ultrasound diagnosis (P<0.05). The diagnostic efficiency of two-dimensional ultrasound combined with four-dimensional ultrasound was good in the diagnosis of fetal cardiac malformation in prenatal period of pregnant women, it could improve detection rate of fetal cardiac malformation and is worthy of being generalized in clinic.
