Disease Description: As subaortic stenosis, but the tightening occurs below the aortic valve.
Inherit Mode: -
Disease Symptom: Symptoms may include but are not limited to: Lethargy ;Syncope (fainting, loss of consciousness); Exercise intolerance; Systolic heart murmur; Weak femoral pulse ;Sudden death
Disease Cause: Subvalvular aortic stenosis is caused by a ridge or ring of fibrous tissue or by fibrous nodules within the left ventricular outflow tract located just below the aortic valve. It is most commonly seen in Boxers, Rottweilers, German Shepherds, Newfoundlands, and Golden Retrievers. It can be a congenital condition, meaning the animal was born with it, or it can develop as he ages.
Disease Diagnose: An electrocardiogram may be able to show the left ventricular enlargement. Doppler echocardiography can also confirm the aortic stenosis if present. The velocity of the systolic blood flow determines the severity of the stenosis. An ultrasound may also be utilized during the diagnostic process. It can show the different chambers of the heart and offer a live feed of the heart pumping. It can allow the veterinarian to see where the flow of blood is altered and by how much. There are other diagnostic imagings your veterinarian may recommend, however you may have to go to a specialist for it. In veterinary medicine, there are cardiologists available that may be better equipped to handle your dog’s case.
Treat Method: Treatment for subvalvular aortic stenosis can be by medical management or by surgical correction.There are also herbal medication, homeopathic remedies, and Chinese holistic medications you can look into in addition to western medicine. This would require you to go to a holistic veterinarian who is practiced in the field, but it can be an extremely beneficial option for your dog. In some cases, you may even utilize a combination of western medicine and holistic medicine for the best treatment plan for him.
Breeder Advice: Some animals show no symptoms of this condition. Ones who are mildly affected typically do not even need treatment. Prognosis in these animals can range from fair to good. For those with a more serious condition, prognosis declines and can become guarded to poor. It is highly recommended animals with this condition are not bred as it is genetic.
