Hi,
My son was also diagnosed with TGA after he is born.
You are lucky that u know it before hand.
I really thank GOD for putting us all in right place at right times.
As soon as he got diagnosed with TGA hours after his birth, he was taken to Children's Hospital in Pittsburgh. We were living in Pittsburgh then.
He was operated in 5 days by great God like doctors and now my son is hail and healthy.
He was operated by Cardio Thoracic Surgeons Dr. Sanjay K. Gandhi and Dr Lee Beerman. Besides they have great team of Cardiologists and great ICU. I suggest you to approach them.
Do not panic and think what you have to do. Make use of resources you have.
May God bless you all!
Thanks for giving me this opportunity to share
