Fetal cardiac findings:
End-diastolic diameters of ventricles, FHR, E and A wave velocities of
mitral and tricuspid valves, MAPSE-TAPSE values, IVCT of both three
segments were similar between groups as presented in the Table 2. IVSd
and LVPWd significantly higher in COVID group (p <0.001,p =0.007 respectively).
Myocardial velocities of both three segments by TDI (Sm,
Em, Am) and IVRT of lateral walls were
found significantly higher and E/A,
Em/Am, E/Em ratios of
both mitral and tricuspid valves were significantly lower, mitral and
tricuspid E wave DT measurements were significantly higher in COVID
group as an indicator of impaired diastolic function (Table 2). MPI
values of both segments calculated significantly higher on COVID group
as an important marker of global ventricular dysfunction
(p <0.001 for LV and RV lateral walls; p =0.009
for bazal septum). Aortic insufficiency (mild) was observed in 3
fetuses, tricuspid insufficiency (mild) observed in 1 fetus, 3 of which
regressed on the follow-up. Anatomy of valves were normal.
