Aim:
Our objective was to investigate the impact on fetal cardiac function and fetal hemodynamics after recovery from severe acute respiratory syndrome coronavirus type 2 (SARS-CoV-2) infection in early pregnancy.
Methods:
A prospective study involving 60 women in pregnancy who had recovered from a previous SARS-CoV-2 infection and 20 control wemen was performed. Between 11 and 14 weeks of pregnancy, women recovering from infection and controls underwent fetal ultrasound evaluation. Ultrasound parameters assessing cardiac function (TAPSE, MAPSE, E/A ratio) and hemodynamics (DV/S, DV-D, DV-A, DV-TAMV, DV-PI, DV-PLI, DV-PVIV) were measured.
Results:
Based on ultrasound measurements, the median gestation age of the groups recovering from SARS-CoV-2 infection (RSI) was 12 (0.5) weeks, while the control group's was 12 (0.7) weeks (p = 0.76). The RSI group and the control group didn't indicate statistically significant differences in ultrasound measurements of cardiac function and hemodynamics (p > 0.05).
Conclusions:
According to our findings, the infection of SARS-CoV-2 in early pregnancy has no substantial influence on fetal cardiac function and fetal hemodynamics in pregnant women. However, the effect on mid-pregnancy to late-pregnancy is not yet known. Future studies will help elucidate the overall impact on fetal cardiac function of SARS-CoV-2 infection.
