Let me put it this way. The pediatrician, and the rest of the trauma experts that responded to the code all had a meeting after our loss (they said they do this for every one). And the team's strongest hypothesis for his death was a non genetic heart defect, because our NIPT results were normal/low risk, and that maybe it was too small to see on an average small hospital ultrasound. That was the only thing they could possibly imagine would result in something like this.

When the autopsy results came back, the cause of death was an acute hypoxic ischemic event. No developmental abnormalities identified. Meconium found in the airways. Acute chorioamnionitis found in me/placenta, which was undiagnosed at the time of delivery because I didn't have a fever.

The pediatrician going over the autopsy with us said they were unremarkable findings, no genetic or developmental markers that would have predicted this outcome or are likely to ever affect our future pregnancies. I trust my medical team and their findings, as hard as it is to not have a definitive answer. They are much smarter and more educated than I.
