The role of visual diagnostics in establishing the stages of development of mitral valve insufficiency in dogs

Abstract

The aim of the work is to develop a scientifically based approach the established role of visual diagnostics in determining the stages of development of mitral valve insufficiency in dogs. The study was conducted on the basis of the Moscow state Academy of Veterinary Medicine and Biotechnology named after K. I. Scriabin. The object of research - 162 dogs with myxomatous degeneration of atriovetricular valves. Myxomatous degeneration of the valvular heart apparatus was more common in dogs aged 7 to 10 years. Most often diagnosed in dogs of Chihuahua breeds, Yorkshire Terriers. Of the total number of animals, the disease was more common in males. Clinical signs of myxomatous degeneration of the valvular heart apparatus in dogs are diverse. Objective diagnostic clinical signs of myxomatous degeneration of the mitral valve of the heart in dogs were: cough, sudden lethargy, shortness of breath, less frequent weight loss, loss of consciousness and ascites. The main clinical signs of tricuspid valve damage were: cough and ascites. Shortness of breath and loss of consciousness were less common. With a combined lesion of the mitral and tricuspid valves, the clinical picture was more pronounced.
