Diabetic and fetal echo!!!

Had my appointment for my fetal echo yesterday and to be honest even though the doctor said not to worry well here I am worried out of my mind. My little ones heart was check and he has all four chambers, but the doctor saw two things. My baby has a hole in the heart, and also one of the vaulves is not functioning well. He said that the baby was under stress and that the vaulve instead of pumping all the blood out its was being done back up. I didn't really know what that means. I was wondering if any of you ladies have gone through this and what was the outcome. I appreciate you taking the time to read this☺️
