OP, if you are, like me, the kind of person who wants to know what actual research has been done on this and related issues, here is a general overview of the research conducted on COVID-19 infection during pregnancy and potential heart damage to the fetus:
Vertical Transmission Potential: Research suggests that there is a possibility of vertical transmission, which means the transmission of the virus from an infected mother to the fetus during pregnancy. Several case reports have indicated the presence of SARS-CoV-2 in the placenta, amniotic fluid, and neonatal tissues, suggesting intrauterine transmission. However, the exact risk, mechanisms, and potential outcomes of vertical transmission are still being investigated further.

Fetal Cardiovascular Effects: Limited research exists regarding direct heart damage to the fetus due to maternal COVID-19 infection. However, some studies have identified potential cardiac abnormalities in neonates born to COVID-19 positive mothers. These include myocardial injury, myocarditis-like symptoms, arrhythmias, and myocardial dysfunction. Further investigations are ongoing to understand the underlying mechanisms and long-term outcomes.

Maternal Cardiac Injury and Pregnancy Outcomes: Maternal COVID-19 infection can lead to cardiovascular complications, such as myocarditis, heart failure, and arrhythmias. These complications may indirectly affect the fetus by compromising maternal health, placental function, or oxygenation. Adverse pregnancy outcomes, including preterm birth, fetal distress, and stillbirth, have been observed in some cases, but the causal relationship is still not well-established.
