The nurse describes pulmonic stenosis as the Narrowing of the valve between the right ventricle and the pulmonary artery.
Pulmonary stenosis is the narrowing of the pulmonary valve, which controls the flow of blood from the heart's proper ventricle into the pulmonary artery. The pulmonary artery consists of blood to the lungs. Stenosis happens when the valve's flaps (cusps or leaflets) are thickened or fused together.
Pulmonary valve stenosis is most customarily a congenital coronary heart defect. the precise reason is doubtful. The pulmonary valve does not increase well as the toddler is developing in the womb. The pulmonary valve is manufactured from three skinny portions of tissue called flaps (cusps).
