What is

Valve Atresia?

Understanding the misshapen heart valve

Valve atresia is quite rare and usually happens because of a birth defect.

Healthy valve

Each of your heart valves has leaflets that open and close when your heart beats to pump blood through your body.

Valve atresia

Valve atresia happens when your heart valve is either smaller, underdeveloped, or missing altogether. Because of this, blood can’t flow right through your heart or to the rest of your body.

Although atresia is usually caused by a birth defect, other types of heart valve disease can happen at any age.
