6 WEEK OLD FULL TERM BABY'S PDA HAS NOT CLOSED?

My 6 week old son was born at full term 41 weeks, a perfectly healthy baby boy, and he went to his routine checkup, and they found that he had a heart murmer, so the following day I went in for some tests, and they noticed his PDA (PATENT DUCTUS ARTENOSUS) has not closed, they said the only thing left to do is surgery which is not open heart; but it is still surgery, this is the hardest thing for me and my family he is a healthy baby boy, is there anyone else that is going through this, have a similar story, or can give me any tips or advise, I'm so scared, and I need some advise, Thank you.
