Probably more than 50% of puppies tested at 10 weeks would have a heart murmur and it will disappear before they are 12 months. Unless the vet asked you to bring the dog back at 4 and 8 months for further tests I would forget all about it, and even if they did I would wait for the further tests when they should explain details of how you handle it.
