I'm thinking you're right. There is no way he can determine what the nature of the heart condition is, or how serious it is, just from listening to it. Not even a certified veterinary cardiologist can do that! Did he even suggest other options besides euthanasia? I personally would be finding another vet, preferably a feline-only one. Your kitty needs some relief from her dental pain NOW, or she's just going to get weaker and weaker and will be an even worse candidate for anesthesia.
