Enlarged heart?

[Gungirl]

Ok... so my husband and I have been looking around for a red-tail. He wants one really bad. We found a young woman who breeds them and has a few for sale. They are priced at $70 each. I'm waiting on pictures from her now. While talking to her she offered us a free one. It's 1yr old eats and sheds fine. Doesn't seem to have any issue other than it has an enlarged heart. She informed us that you can see where the heart is due to it leaving a small lump on the snake.
My question is do you think this snake is going to need a lot of vet care or could it live happily with this defect? I know with out seeing it or having any hands on its hard to say but what are your thoughts?
