Endocarditis of the aortic valve in the dog.
The clinical features of endocarditis of the aortic valve in 24 dogs were reviewed. This condition was found most commonly in large-breed, middle-aged male dogs. Evidence of antecedent infection or immunosuppression was usually not historically verified or found at necropsy. However, an association with congenital heart disease, especially discrete subaortic stenosis, was demonstrated. The most frequent clinical findings were systolic and diastolic murmurs and bounding arterial pulses, with or without signs of congestive heart failure. The most commonly isolated organisms were Corynebacterium sp, Erysipelothrix rhusiopathiae, and Streptococcus sp. In addition to antibiotic therapy, treatment for congestive heart failure often was required. Despite aggressive therapy, most affected dogs died as a result of congestive heart failure, arrhythmias, infarction, sepsis, or renal failure.
