Aortic regurgitation associated with chronic bacterial endocarditis in one adult thoroughbred gelding

This article describes chronic bacterial endocarditis as the cause of aortic regurgitation in a 25-year-old Thoroughbred used for horseback riding. The horse presented signs of depression, exercise intolerance, and weight loss. A pandiastolic murmur was identified, but no other clinical signs of bac...
