The Mighty Hearts Project was founded by owners of dogs who have benefited from surgical intervention with Dr. Masami Uechi in both Versailles, France and at his clinic, JASMINE, in Japan.  Each founding member has had a unique experience with their dog's diagnosis, pre-surgical treatment, intervention, post-surgical challenges, and recoveries.  We feel passionately about bringing visibility to this surgery by sharing our knowledge and experience with the world.  Our goal is to advance the care for dogs by collaborating with veterinarians and other supporters globally to bring you current research and updates on emerging techniques regarding mitral valve disease and repair.

We believe in educating dog owners about the most viable option for advanced treatment of mitral valve disease.  We support bringing awareness to veterinary professionals about Dr. Masami Uechi's repair technique and the surgeries being performed throughout all the clinics worldwide.  We encourage cardiologists to increase their knowledge and exposure to this technique to better help their patients. 



By increasing the demand for advanced care, we also wish to leverage the collective global interest in this technique by bringing internationally known inventor of mitral valve repair surgery in small breed dogs, Dr. Masami Uechi, to the US for direct interventions with dogs with mitral valve disease and mentor up and coming veterinary talents to be able to perform this technique with confidence saving more lives. 




We support dog owners from the inception of their diagnosis, through their decision-making process on what type of care is best for their family, all the way through intervention if they choose to take that path.  We also support emerging research on mitral valve disease and share the best possible proven options for dog owners.
