Can human heart failure interventions work in dogs?

Mitral regurgitation is the most prevalent valvular heart disease in humans. It's also common among dogs, especially older and smaller breed dogs. In both species, the mitral valve fails to close tightly enough to keep blood from flowing back into the left atrium as the heart is contracting. Untreated, it can lead to heart failure. Surgery is often needed to repair this issue in humans. For dogs, treatment has historically been less advanced, but veterinarians and animal researchers are taking cues from the human health world.
