High nuchal translucency

I'm ftm turning 42 this year. I did nipt and scan at week 13. The nipt scan results was fine with low risk in down syndrome. However the nt scan is very bad at 7.6mm and doctor said this could indicate risk of other chromosomal or genetic abnormalities or even heart defect. She doesn't do amniocentesis and recommended me to go to another doctor for amniocentesis. Anyone has similar experience to share?
