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.
