Canine Aortic/Subaortic Stenosis (AS/SAS) is a congenital heart defect that affects the heart’s left ventricle. It’s caused by the aortic valve or subaortic area narrowing, which restricts the flow of blood from the left ventricle to the aorta. This can lead to an increased pressure in the left ventricle, which can cause symptoms such as exercise intolerance, fainting, and even sudden death.
AS/SAS is most commonly seen in large dog breeds, particularly Boxer and Bulldog breeds. It’s also seen in some smaller breeds such as the Chihuahua and Pomeranian. The condition can be diagnosed through an echocardiogram, which is an ultrasound of the heart.
It’s important to note that AS/SAS can be managed with proper treatment and care. It’s also important to know that this condition can be fatal if left untreated. It’s important to have your pet examined by a veterinarian if you suspect they may have this medical problem.
Symptoms of Canine Aortic/Subaortic Stenosis (AS/SAS)
The most common symptoms of AS/SAS are:
- Exercise intolerance
- Fainting
- Sudden death
Other signs may include difficulty breathing, coughing, and a decreased appetite. If your pet has any of these symptoms, it’s important to have them examined by a veterinarian as soon as possible.
Stages of the Canine Aortic/Subaortic Stenosis (AS/SAS)
AS/SAS is typically split into three stages:
Stage 1
Mild narrowing in the aortic valve or subaortic area. This stage may not cause any symptoms and can often be managed with medications.
Stage 2
Moderate narrowing in the aortic valve or subaortic area. Symptoms may begin to appear at this stage, and treatment may include medications and/or surgery.
Stage 3
Severe narrowing in the aortic valve or subaortic area. Symptoms are usually more severe at this stage, and treatments include medications and/or surgery.
Treatment for Canine Aortic/Subaortic Stenosis (AS/SAS)
The treatment for AS/SAS will depend on the stage of the condition. Treatment may include medications to reduce the pressure in the left ventricle, or surgery to widen the aortic valve or subaortic area. In some cases, a combination of both treatments may be needed.
It’s important to note that even with proper treatment and care, AS/SAS can still be fatal. It’s important to have your pet examined by a veterinarian if you suspect they may have this condition.
Preventing Canine Aortic/Subaortic Stenosis (AS/SAS)
Unfortunately, there is no way to prevent AS/SAS. Early diagnosis and treatment can help reduce the risk of complications and improve the prognosis for your pet.
