Mighty Hearts Project helps pet parents access life-saving mitral valve repair surgery under bypass for dogs diagnosed with mitral valve disease when they’ve been told there are no options left.
If you’ve been told there’s nothing that can be done — you’re not alone. Many vets in the U.S. don’t offer solutions for mitral valve disease, leaving families heartbroken and out of hope. But there is a proven surgical option. And we’re here to help you understand it.
Comprehensive education for pet parents, veterinarians, and the general public about mitral valve disease in dogs. Through expert-led webinars, guides, and informative blogs, we raise awareness about the signs, treatment options, and available surgeries for mitral valve disease.
A collection of resources designed to support dog parents navigating the complexities of mitral valve repair surgery under bypass. From detailed surgery information and travel guides, to nutritional recommendations and post-operative care advice, we provide tools to support dogs and their parents.
A community of dog parents and advocates united by the shared goal of improving the lives of dogs with mitral valve disease. Through our Facebook group, social spaces, and educational events, we foster a space for pet parents to connect, share experiences, and find support.
What was once considered only a palliative prognosis, surgical intervention to repair the mitral valve and heart chords is now possible. We want to share this information with pet owners, vets, and researchers globally in an effort to advance the care and demand for this lifesaving option. This website provides extensive knowledge and resources about leading surgery clinics, the application process, travel guidance and more.
We give hope to owners of dogs suffering with Mitral Valve Disease. From the inception of diagnosis, throughout their decision-making process on type of care and all the way through surgery if they should choose to take that path.
