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.
