Can aortic stenosis cause sudden death?

Sudden cardiac death (SCD) is a significant concern in asymptomatic patients with aortic stenosis (AS) with a reported incidence of up to 3%/year. However, whether AS alone puts patients at risk independent of non-valve related factors, including coronary heart disease, is unclear.

How serious is subaortic stenosis?

As the obstruction worsens, some patients may have chest pain or pass out during exercise or exertion. Others may develop fast heart beats or, rarely, congestive heart failure as fluid builds up in the heart. Patients with severe or untreated subaortic stenosis may be at risk for sudden cardiac death.

What are the end stages of severe aortic stenosis?

If left untreated, severe aortic stenosis can lead to heart failure. Intense fatigue, shortness of breath, and swelling of your ankles and feet are all signs of this. It can also lead to heart rhythm problems (arrhythmias) and even sudden cardiac death.

Is subaortic stenosis genetic?

Subaortic stenosis appears to be genetic in origin; the first signs of it may be present at birth (moderate or severe cases) or may appear in the first year of life (usually milder cases).

Is subaortic stenosis a heart disease?

Subvalvular aortic stenosis is a congenital heart defect that occurs during fetal development. The precise cause is unknown, but genetics may play a role. Subaortic stenosis has also been associated with several congenital syndromes.

Is subaortic stenosis rare?

Subaortic stenosis, also called subvalvular aortic stenosis or SAS, is a rare heart defect that affects 1% of infants who are born with congenital heart defects.

Is heart failure death painful?

In more than half of all people with heart disease, death follows within an hour of an attack, as the heart stops pumping blood, and hence oxygen, to the brain. But chronic congestive heart failure brings a slower, more painful death.
