SAS (Sub Aortic Stenosis)
|Subaortic stenosis (SAS) refers to a narrowing of the area below the aortic valve due to an abnormal fibrous band of tissue. This fibrous band can be present at birth or develop over the first year of life. SAS ranges in severity from mild, moderate to severe. For more information, go to Cardiac Disease Reference|
Breeds predisposed to SAS should be screened by echocardiogram. Because the lesion reaches its full severity by 2 years of age it is advised to have an echocardiogram done at 18-24 months of age.
Breeds: Bernese Mountain Dog, Boxer, Bouvier, Bull Terrier, Bulldogs, German Shepherd Dog, German Shorthaired Pointer, Great Dane, Golden Retriever, Newfoundland, Samoyeds, and Rottweiler.
