A situation, in which the opening of a cardiac valve is not complete and thereby the passage of blood through it is impaired.
Blood flow through a narrowed valve is usually manifested by a murmur, which can be heard during the phase when blood is flowing through the valve.
Clinical symptoms depend on the severity grade of the stenosis.
Usually, the cardiac compartment that must push blood through the stenosed valve is overloaded with work and the increased burden can cause structural changes of the affected compartment.
In addition, symptoms of congestion and edema may be present because of incomplete voiding.
If necessary, surgical correction is performed.
