How long do dogs live with aortic stenosis?
While dogs with mild or moderate SAS often have minimal clinical signs and a normal life span, dogs with severe SAS carry a more guarded prognosis. Recent data reports an average survival time of 5-7 years in these patients.
Does severe aortic stenosis require surgery?
Mild to moderate aortic stenosis typically does not require surgery. But, surgery is necessary for severe cases of aortic stenosis. If left untreated, severe aortic stenosis can result in heart failure.
What does it mean when a dog has aortic stenosis?
Aortic stenosis is a condition of the heart in which there is a narrowing of the aortic valve of the heart that controls the flow of blood from the left ventricle. The lesion of aortic stenosis in the dog commonly occurs in the subvalvular position, and thus the condition is called subaortic stenosis.
What to do for dog with narrowed aortic valve?
Catherization may also be used to widen the narrowed vessels, but the procedure does not demonstrate survival advantages for dogs with severe forms of the disease. Typically, broad spectrum antibiotics are given to dogs with aortic stenosis due to the increased risk of developing bacterial infections in the heart.
What kind of heart disease does a dog have?
Aortic stenosis is a heart disease that is more common in certain dog breeds. Aortic stenosis describes a narrowing at the aortic valve of the heart. The aortic valve is the valve through which blood leaves the heart, traveling to the rest of the body.
Is there a cure for subaortic stenosis in dogs?
There is no cure for subaortic stenosis. Since it is thought to be of genetic origin it is often recommended that dogs with subaortic stenosis not be bred to avoid passing the disease along to future generations. If the disease is mild, treatment is not required.
What is the life expectancy of aortic stenosis?
As mentioned previously, medically managed treatment of severe aortic stenosis has a dismal prognosis, with an overall mean survival of 3 years from the onset of symptoms. Surgical valve replacement essentially cures patients — restoring an almost normal life expectancy.
Can aortic stenosis be reversed?
However, there are no medications that can reverse aortic stenosis. The only cure is replacing the diseased valve. Usually, heart valve replacement requires open-heart surgery. During this procedure, patients are connected to a heart-lung bypass machine, which does the work of the heart while their heart is stopped.
How long does someone with aortic stenosis live?
Depends on symptoms. Patients with uncorrected aortic stenosis have a poor survival: half of the patients that develop angina ( chest pain) will die within 5 years, half of the patients that develop syncope (passing out) will die within 3 years, and half of the patients that develop heart failure will die within 2 years.
What is end stage aortic stenosis?
Aortic-valve stenosis is a progressive condition; end-stage disease leads to death due to obstruction of left ventricular outflow. Aortic-valve replacement is the only effective therapy.
