In mild cases of aortic stenosis, treatment is typically not required. Your dog may be closely monitored for signs of disease progression, but medication is not typically needed. In moderate to severe cases, long-term medication may be required.
How long do dogs live with aortic stenosis?
Recent data reports an average survival time of 5-7 years in these patients. Many will suffer from exercise intolerance or fainting episodes, and a significant number will have fatal collapse episodes prior to middle age. Those that live to middle age may eventually develop congestive heart failure.
What causes aortic stenosis in dogs?
Aortic stenosis, typically caused by a ridge or ring of fibrotic tissue in the subaortic region (subaortic stenosis), is a common congenital defect of large breed dogs. The condition is typically associated with a loud ejection murmur and weak peripheral pulses in more severely affected dogs.
Does aortic valve stenosis go away?
Your treatment depends on the severity of your condition. You may need surgery to repair or replace the valve. Without treatment, severe aortic valve stenosis can lead to death.
What happens if you don't fix aortic stenosis?
