Pulmonic stenosis is a relative narrowing of the valve from the right ventricle to the lungs. Initially, this congenital abnormality is usually silent - your doctor will not be able to hear anything abnormal even on careful examination. Eventually, a short ejection (crescendo-decrescendo) murmur will be heard in the area of the pulmonic valve, classically with a "click" which signifies the walls of the pulmonic valve snapping outward with each pumping stroke. Pulmonic stenosis is rarely cause for concern except for endocarditis prophylaxis. See also pulmonary branch stenosis.
