Is Multiple Pregnancy Really a Risk Factor? Fetal Echocardiography
Results in Tertiary Care Center
Objectives: The aim of this study was to analyze the frequency and
results of congenital heart defects (CHD) in multipl pregnancies by
fetal echocardiography. Method: This retrospective study was conducted
at our hospital between January 2016 and September 2019. A total of 9440
pregnant women were enrolled in this study, including 241 were multiple
pregnancies. (232 twins, 7 triplets and 2 quadruplets). Results: The
prevalence of CHD was significantly higher in twin pregnancies (p=0.05).
The rate of CHD was present in singletons 4.31% and twins 8.7%. There
was no statistically significant difference between the two groups with
respect to rate of critical congenital heart disease (p=0.32).
Conclusion: Multiple pregnancies had increased congenital heart defect
risk compared with singleton. Therefore, it is important to refer for
fetal echocardiography when necessary.
