Tetralogy of Fallot is a congenital heart defect consisting of four abnormalities that affect the heart’s ability to pump enough oxygenated blood to the body (Eldredge, et. al., 2007). Statistics on prevalence of tetralogy of fallot in dogs and cats were not found in the literature. The four abnormalities that make up Tetralogy of Fallot are as follows:
Symptoms and treatment for Tetralogy of Fallot are similar to those of other congenital heart diseases (see Valvular Dysfunction and Cardiomyopathy). The literature does not suggest that surgery is readily available for dogs or cats born with this disease.
