Hypoplastic left heart syndrome HLHS

Hello everyone, I just went for a growth scan today and the ultrasound tech states that, my baby has hypo-plastic left heart syndrome, although all other measurements are fine. I am 16 weeks, and I was wondering if anyone has every experienced this personally or know of someone who’s baby has. Or knows if this can be reversed as baby is still developing in the womb. Please and knowledge will help as I am worried
