Abstract
Background: Aging is a biological process, which affects many body systems and increases susceptibility to disease that is associated with a reduction in immune response, a decline in cognitive function and a diminished functional reserve of the cardiovascular, pulmonary and renal systems. Diseases of heart or cardiovascular system represents a major component of geriatric medicine among which, myxomatous mitral valve disease is more common among geriatric dogs. The present study is keeping on record about the diagnosis of myxomatous mitral valve disease in geriatric dogs in and around Hyderabad, Telangana state.Methods: A total of1695 geriatric dogs presented to various clinics including university veterinary clinical complex of Hyderabad, Telangana state during 2015 to 2020 were considered for this study. After confirming that they were free from any other systemic disease, medium to large size breed dogs above 8 years with the history of exercise intolerance, dyspnoea and cough were selected. Diagnostic protocol included, auscultation, chest x-ray and 2d-echocardiography to confirm mitral valve degeneration. Result: Myxomatous mitral valve disease was diagnosed in 427/695 geriatric dogs (61.43%) and were showing hyperechoeic thick mitral valve leaflets with kinking and prolapse. Further, echocardiography also revealed dilated left atrium and ventricle, hyperkinesis of interventricular septum, mitral valve degeneration and rupture of chordae tendineae with valuvular regurgitation.
