Similar to the aortic valve , the pulmonary valve opens in cardiac cycle ventricular systole , when the pressure in the right ventricle rises above the pressure in the pulmonary artery. At the end of ventricular systole, when the pressure in the right ventricle falls rapidly, the pressure in the pulmonary artery will close the pulmonary valve. The closure of the pulmonary valve contributes the P2 component of the second heart sound S2 . The right heart is a low pressure system, so the P2 component of the second heart sound is usually softer than the A2 component of the second heart sound.

Pulmonic stenosis , also known as Pulmonarystenosis , is a dynamic or fixed obstruction to flow from the right ventricle of the heart to the pulmonary artery . It is usually first diagnosed in childhood. Pulmonic stenosis is usually due to isolated valvular obstruction Pulmonaryvalvestenosis , but may be due to subvalvular or supravalvular Stenosis of pulmonary artery obstruction. It may occur in association with more complicated congenital heart disorder s. Pathophysiology When pulmonarystenosis PS is present, resistance to blood flow causes right ventricular hypertrophy. If right ventricular failure develops, right atrial pressure will increase, and this may result in reopening of the foramen ovale , shunting of unoxygenated blood into the left atrium, and systemic cyanosis . If PS is not severe, congestive heart failure occurs, and systemic venous engorgement will be noted. An associated defect such as a patent ductus arteriosus partially compensates for the obstruction by shunting blood from the aorta to the pulmonary artery and into the lungs.

Subglottic stenosis is a congenital or acquired narrowing of the subglottic airway . Although it is relatively rare, it is the third most common congenital airway problem after laryngomalacia and vocal cord paralysis . Subglottic stenosis can present as a life threatening airway emergency. It is imperative that the Otolaryngologist be an expert at dealing with the diagnosis and management of this disorder. Subglottic stenosis can affect both children and adults. Subglottic stenosis can be of two forms, namely Congenital subglottic stenosis and Acquired Subglottic stenosis. As the name suggests, Congenital subglottic stenosis is a birth defect. That is a child is born with it. Acquired Subglottic Stenosis generally follows as an after effect of airway intubation.

The valve is completely closed thereby obstructing the outflow of blood from the heart to the lungs . The pulmonaryvalve is located on the right side of the heart between the right ventricle and pulmonary artery . In a normal functioning heart, the opening to the pulmonaryvalve has three flaps that open and close like one way doors. As these flaps open and close they allow blood to flow forward into the pulmonary artery and on to the lungs ... . With the disease pulmonary atresia, the flap like openings are completely covered by a layer of tissue ... oxygenated blood for survival.
