Heart valve disease disrupts the flow of blood through your heart in two ways:
- Regurgitation means blood leaks backward through the valve because it does not close completely. This allows too much blood to remain in the heart.
- Stenosis means the flaps that open and close the valve have thickened or stiffened. This shrinks the valve opening and requires the heart to pump harder to circulate blood.
Without treatment, heart valve disease can lead to heart failure, stroke, arrhythmia, and other serious problems.
