Left sided congestive heart failure due to severe aortic degeneration and insufficiency in a dog –a case report

Abstract

Aortic degeneration is an uncommon finding in dogs with uncertain etiology, being associated with endocrine disorders which may induce hypercalcemia, hyperkalemia, or with toxicosis, renal disorders and endocarditis. This entity may develop a diastolic volume overload leading to left sided congestive heart failure. The aim of this study is to report and discuss a case of a dog with left sided congestive heart failure due to severe aortic regurgitation associated with myxomatous mitral valve disease and systemic hypertension.
