Clinical Diagnostic Value of Two-Dimensional and Four-Dimensional Echocardiography in Fetal Cardiac Tumor


 This paper aims to investigate the clinical diagnostic value of two-dimensional and four-dimensional echocardiography in fetal cardiac tumor. Material and Methods: A total of 24 pregnant women whose fetus had suspected cardiac tumor in The No.4 Hospital 1946 Jinan Shandong from February
 2011 to April 2018 were selected as objects of study, including 18 cases whose fetus was pathologically diagnosed with fetal cardiac tumor (+) and 6 cases whose fetus was diagnosed with fetal cardiac tumor (−). Results:These patients were retrospectively analyzed. The tumor site, size,
 activity and fetal edema predicted using two-dimensional and four-dimensional ultrasound images were compared with pathological examination results, and the diagnostic value of the two kinds of echocardiography in fetal cardiac tumor was analyzed. The echocardiographic results revealed that
 there were no statistically significant differences in the four-dimensional ultrasonic diagnosis and two-dimensional ultrasonic diagnosis results compared with pathological diagnosis results (p>0.05). In terms of the diagnostic value, the sensitivity, specificity and diagnostic accordance
 rate in the clinical diagnosis of fetal cardiac tumor were 66.67%, 50.00% and 62.5%, respectively, in two-dimensional echocardiography, and 94.44%, 83.33% and 91.67%, respectively, in four-dimensional echocardiography. Conclusions: Echocardiography can determine the activity, shape, site,
 size, etc., of primary cardiac tumor. Two-dimensional and four-dimensional ultrasonic diagnosis can be used to observe the fetal cardiac tumor, thus making an early diagnosis. The sensitivity, specificity and diagnostic accordance rate of four-dimensional echocardiography in the clinical diagnosis
 of fetal cardiac tumor are significantly higher than those of two-dimensional echocardiography, so four-dimensional echocardiography has higher diagnostic value in fetal cardiac tumor.
