Prognosis

Prognosis will vary depending on

a) If the echocardiographic features are those of feline dilated cardiomyopathy:

• the prognosis is very poor

b) If the echocardiographic features are those of feline hypertrophic cardiomyopathy:

• the prognosis for complete recovery with surgical excision or radioactive iodine therapy is excellent

Comment: Recall that most of these cats are quite old and therefore are subject to a number of geriatric disorder including: chronic renal disease, and hepatic disease which may render them poor anesthetic risks. Many cats can be controlled long term with chronic anti-thyroid therapy if adverse blood disorders do not occur.
