Susan,
I cook this often. It does smell just terrible while cooking, but it is supposed to be very good, I’m not sure that it will help the heart murmur though. 🙁
Faith,
I don’t know that the chicken hearts would do anything special to help, but feeding more fresh food (cooked or raw) is better overall for any dog. It’s not that expensive to buy some fresh meat and vegetables, cook it in a crock pot and add a bit of the mix to his kibble.
Here is Karen Becker’s link on heart murmurs just to give you some additional info:

Good luck with your pup! 🙂
