Tricuspid Valve Dysplasia
|The valve consists of 3 irregular shaped flaps. During fetal development these flaps are attached to the septum. As the fetus matures these bonds, which hold the flaps open, degrade leading to a functioning valve which closes tightly when the right ventricle contracts. Failure of these bonds to degrade commonly causes tricuspid valve dysplasia to occur. |
Breeds predisposed to this should be screened by echocardiogram.
Breeds: Borzoi, German Shepherd, Great Dane, Labrador Retriever, and Weimaraner.
