Abstract:
ObjectiveTo evaluate the correlation between ultrasound detected fetal heart abnormality and chromosomal abnormality.Methods The data of 3307 cases of prenatal fetal echocardiography and karyotype analysis results were retrospectively analyzed.The correlation between heart abnormality and chromsomal abnormality was analyzed.ResultsIn 3307 cases d pregnant women,194cases (5.87％) were found signs of fetal heart abnormality,and 3113 cases (94.13％) were not found any sign of fetal heart abnormality.And 124 cases(3.75％) were found chromosomal abnormality.The rate of chromosomal abnormality in fetus with heart abnormality was higher than that in fetus without heart abnormality[ 19.59％ (38/194) vs.2.76％ ( 86/3113 ),P ＜ 0.01 ],the relative risk ratio was 7.0903.One hundred and twenty-four cases of chromosomal abnormality in the 18-three-body(42 cases) and 21-three-body(36 cases) were the most common.ConclusionsFetal heart abnormality incidence of chromosomal abnormality is high relatively.When the signs of heart abnormality are found,it is suggested that the fetus should examine karyotype analysis.
