Is Supravalvular aortic stenosis serious?

Is Supravalvular aortic stenosis serious?

If SVAS is not treated, the aortic narrowing can lead to shortness of breath, chest pain, and ultimately heart failure. The severity of SVAS varies considerably, even among family members. Some affected individuals die in infancy, while others never experience symptoms of the disorder.

Which syndrome is associated with Supravalvular aortic stenosis?

Supravalvular aortic stenosis (SVAS) can either be isolated or can occur as part of Williams syndrome.

How can you tell the difference between aortic stenosis and pulmonary stenosis?

Unlike the aortic stenosis murmur, a pulmonic stenosis murmur does not radiate, and the crescendo component lengthens as stenosis progresses. The murmur grows louder immediately with Valsalva release and with inspiration; the patient may need to be standing for this effect to be heard.

What is Supravalvular pulmonary stenosis?

Supravalvular pulmonic stenosis, also known as peripheral pulmonary stenosis, is a functional obstruction originating from the pulmonary artery. The blockage may occur at the main artery, bifurcation point, at distal branches of the pulmonary artery, or any combination thereof.

What can aortic stenosis lead to?

Aortic valve stenosis may lead to heart failure. Heart failure signs and symptoms include fatigue, shortness of breath, and swollen ankles and feet.

What is pulmonary stenosis in adults?

Pulmonary valve stenosis in the adult patient: pathophysiology, diagnosis and management | Heart.

How is Supravalvular aortic stenosis treated?

Surgery is the primary treatment for supravalvar aortic stenosis (SVAS). Children and adolescents with catheter peak-to-peak (or Doppler mean) gradient of 50 mm Hg or more should have surgical intervention. The choice of procedures in these patients is similar to that indicated for valvar aortic stenosis.
