Clinical and pathological findings of severe subvalvular aortic stenosis and mitral dysplasia in a rottweiler puppy.
Subvalvular aortic stenosis (SAS) and mitral dysplasia were diagnosed in an asymptomatic eight-week-old rottweiler. Clinical and pathological findings were compatible with a fixed and dynamic obstruction of the left ventricular outflow tract. Gross and microscopic pathological findings were consistent with the most severe form of SAS, described previously in Newfoundland dogs over six months of age. These observations demonstrate that very young asymptomatic puppies may suffer a severe complex form of SAS.
