|Classification and external resources|
Pulmonary insufficiency (or incompetence, or regurgitation) is a condition where the pulmonary valve is not strong enough to prevent backflow to the right ventricle. If it is secondary to pulmonary hypertension it is referred to as a Graham Steell murmur.The three primary pathological mechanisms causing pulmonary insufficiency, are dilatation of the pulmonic valve ring, acquired alteration of pulmonic valve leaflet morphology, or congenital absence or malformation of the valve.
