Structural Findings
Rizzo et al. found no difference in umblical vein blood flow, atrial
area, ventricular sphericity indices (VSİ) between pregnancies
complicated by SARS-CoV-2 infection during second half of pregnancy
compared to those not complicated by infection [20]. Fetal cardiac
morphological parameters (VSİ, İVS and lateral wall thicknesses) were
found to be similar between group of pregnancies who were after recovery
of COVID-19 and non-COVID group by Goncu et
al. [21]. In our
study, we found significantly higher LVPW and IVS thicknesses in all
periods. In keeping with this, LV mass and LVMi were significantly
higher in postnatal echoes like fetuses and infants born to gestational
diabetic mothers [22, 23]. These structural changes were
significantly correlated with tricuspid E wave which demonstrates
passive phase of ventricular filling. This may be due to decreased
ventricular compliance associated with the increase in septum and
posterior wall thickness, like cardiac findings of infants of diabetic
mothers. This thickening may be due to myocarditis in the inflammatory
process.
