DULUTH, Ga., June 21, 2022 /PRNewswire/ –– Boehringer Ingelheim Animal Health today announced that the United States Center for Veterinary Medicine (FDA-CVM) has granted conditional approval to VETMEDIN®-CA1 (pimobendan), which is indicated for delaying the onset of congestive heart failure in dogs with preclinical myxomatous mitral valve disease (MMVD) stage B2, a form of chronic valvulopathy in dogs.

About Canine Valvular Heart Disease

According to the American College of Veterinary Internal Medicine (ACVIM), MMVD is the most common heart disease in dogs in many parts of the world, accounting for approximately 75% of cases of heart disease seen in dogs by veterinary practices in North America. It is estimated that approximately 10% of dogs presented to primary care veterinary practices have heart disease.

According to the ACVIM 2019 consensus statement, canine valvular heart disease in dogs stage B2 refers to asymptomatic dogs that have met specific criteria, including a moderate or loud heart murmur and severe cardiac enlargement.
