I don't know about heart murmurs in puppies, but my good friend's daughter (human) has a heart murmur and they have had to restrict her activity level and take her in for annual exams ($$ and worry).
The decision to take Mango with that knowledge is totally up to you. Will the breeder reduce the price to compensate for medical expenses to come? Are you willing to take Mango to the vet as often as needed and restrict activity as much as will be needed? Would it be better to wait for another puppy? It's totally up to you. (Please don't answer these questions for me or anyone else. I'm just trying to prompt some questions for you that come to my mind.)
I would recommend that you make an appointment to go talk to your veterinarian as soon as possible and find out what he/she thinks. S/he will give you much better questions to ask from his/her training. S/he he has much better knowledge than 99.9% of us.
