Types of heartvalve disease

Four valves.
Three types of disease

Your heart has four valves: aortic, mitral, tricuspid, and pulmonary. All four of them can develop different kinds of heart valve disease: stenosis, regurgitation (insufficiency), and atresia.

Stenosis

Your valve becomes stiff and has a small opening, which limits your blood flow.

Regurgitation

Your valve doesn’t close all the way, letting blood flow back into your heart.

Atresia

Your valve isn’t formed correctly and is blocked by solid tissue.
