Pulmonary valve: The pulmonary valve is located in the heart between the right ventricle and the pulmonary artery. The pulmonary valve ensures that blood flows from the right ventricle into the pulmonary artery in only one direction. In a healthy person, the pulmonary valve has three cusps that open in one direction as blood is pumped through the valve into the pulmonary artery. The pulmonary valve then closes and makes a seal to prevent the backflow of blood back into the right ventricle. The pulmonary valve is opened by the increased pressure created by the pumping action of the chambers of the heart.
Conditions that afflict the pulmonary valve include pulmonic valve disease, valvular heart disease, pulmonic regurgitation, pulmonic stenosis, myocardial infarction, infection, congenital valve disease, and heart disease.
