In the 1960s, a French surgeon named Alain Carpentier looked at the possibility of using animal valves to replace diseased human valves, which would eliminate the need for blood thinners. He used mostly pig heart valves, and treated them with a chemical that helped prevent the body from rejecting the valves.

What causes a dog to have a enlarged heart?
This disease of dogs arises when abnormal tissue near the pulmonic valve obstructs the flow of blood out of the right ventricle. If severe enough it can eventually lead to an enlarged right heart and regurgitation of blood through the tricupid valve and into the right atrium. If severe enough right sided CHF might occur.
How old do dogs have to be to get heartworms?
Dogs and cats of any breed can be infected, although we tend to see it more in large male dogs. Since it takes at least 6 months from the time a mosquito injects microfilaria into a dog until these microfilaria become adult heartworms, puppies must be at least 6 months of age before adult heartworms are present. Most dogs are diagnosed at middle age.
