What indicates severe aortic stenosis?

Severe aortic stenosis (AS) is currently defined by an aortic valve area (AVA) <1.0 cm2 and/or a mean transaortic pressure gradient (MPG) >40 mm Hg and/or a peak aortic jet velocity (Vmax) >4 m/s.

Which of the following symptoms of aortic stenosis has the poorest prognosis?

In general, the presence of low-gradient “severe stenosis” (defined as aortic valve area < 1.0 cm2 and mean gradient 40 mmHg), representing up to 40% of all patients with aortic stenosis, is considered to be associated with a poor prognosis.

What are the most common presenting symptoms in a patient with severe aortic stenosis?

The classic triad of symptoms of aortic stenosis occur on exertion and include dyspnea, syncope, and angina. The development of aortic stenosis takes many years and is initially asymptomatic.

What are the stages of aortic stenosis?


C2 Asymptomatic severe AS with LV dysfunction
D1 Symptomatic severe high-gradient AS
D2 Symptomatic severe low-flow/low gradient AS with reduced LVEF
D3 Symptomatic severe low gradient with normal LVEF

What is the life expectancy of someone with aortic stenosis?

The prognosis of untreated aortic valve stenosis once symptoms have begun is poor, with the average life expectancy of a few years. However surgical treatments can usually halt the natural history of the disease before end stage heart failure has set in.

What are the signs of aortic stenosis?

Signs and symptoms of aortic stenosis are due to heart failure and include chest pain, shortness of breath, and lightheadedness or fainting.

How to tell if aortic stenosis is mild?

Symptoms of aortic stenosis may include: Breathlessness. Chest pain (angina), pressure or tightness. Fainting, also called syncope. Palpitations or a feeling of heavy, pounding, or noticeable heartbeats. Decline in activity level or reduced ability to do normal activities requiring mild exertion.

Does mild aortic stenosis need 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.
