stenosis describes the inability of the valve to open to its
normal position.
Valvular dysfunction often appears as one of two major
types, either a stenosis or a regurgitation. A
stenosis describes the inability of the valve to open to its
normal position.
Regurgitation describes the inability of the valve to
effectively shut and impede the backward flow of blood. The
regurgitation of blood can cause a
jet lesion on the wall of the
chamber opposite the regurgitation.
