What is Subaortic Stenosis in Dogs?
Subaortic stenosis is a congenital narrowing of the area underneath one of the heart’s valve (the aortic valve), which leads to some degree of obstruction of the blood flow through the heart. This narrowing makes it harder for the heart to pump blood to the body, which in severe cases, can have serious detrimental health effects. This disease occurs most often in dogs than cats, and it is most commonly seen in large-breed dogs.

Treatment of Subaortic Stenosis in Dogs
Mild cases of subaortic stenosis do not require treatment. Dogs with moderate or severe subaortic stenosis usually receive cardiac drugs that will ease the heart’s workload. Controlling or avoiding bursts of sudden activity or any intense exertion is usually recommended to dogs with subaortic stenosis. Surgical procedures such as balloon catheterization, have been used in veterinary medicine with variable rates of success.
