It is rarely noted in cats. 8 hours agoTo identify the predictive value on time to onset of heart failure HF or cardiac death of clinical radiographic and echocardiographic variables as well as cardiac biomarkers N-terminal pro brain natriuretic peptide NT-proBNP and cardiac troponin I in dogs with preclinical myxomatous mitral valve disease MMVD. Myxomatous valvular degeneration MVD is a slowly progressive condition that affects heart valve anatomy and function in middle-aged to older dogs. Treatment of dogs with compensated myxomatous mitral valve disease with spironolactone-a pilot study.

As the diseased mitral valve degenerates myxomatous transformation -- the development of excess connective tissue that thickens the spongiosa and separates collagen bundles in the fibrosa -- causes the valve to lose its flexibility its leaflets thickening and shortening its fibers stiffening and its chordae tendineae elongating. The EPIC Study-A Randomized Clinical Trial Administration of pimobendan to dogs with MMVD and echocardiographic and radiographic evidence of cardiomegaly results in prolongation of preclinical period and is safe and well tolerated. As are most canine diseases with genetic underpinnings risk of MMVD is greatly increased in a subset of breeds.

Occasionally mitral valve prolapse may lead to valve leakage chest pain pulse irregularity BACTERIAL ENDOCARDITIS and rarely HEART FAILURE.
