Stenosis pulmonary valve stenosis. Medical search. Frequent questions

Pulmonary valve stenosis can cause the heart to work harder, ultimately damaging the muscle and leading to heart failure, while pulmonary valve regurgitation can cause enlargement in the right ventricle, one of the four chambers of the heart. (emoryhealthcare.org)
The pulmonary valve is located between the right ventricle and the pulmonary artery. (healthline.com)
The pulmonary valve functions as a one-way valve that allows blood to move from the right ventricle (pumping chamber) into the artery to the lungs and prevents blood from leaking back into the right ventricle. (childrenshospital.org)
The pulmonary valve has three leaflets (flaps) which open as the right ventricle contracts (squeezes) to allow blood to go to the lungs and then closes as the ventricle relaxes to prevent blood from running backward (regurgitation). (childrenshospital.org)
If this valve does not open normally, the right ventricle must work harder to develop enough pressure to push blood through the narrow opening in the valve. (childrenshospital.org)
Pulmonary valve stenosis is a narrowing of the pulmonary valve (sometimes called the pulmonic valve), which opens to allow blood to flow from the right ventricle to the lungs. (msdmanuals.com)
The heart valve between the right ventricle and the artery to the lungs is narrowed. (msdmanuals.com)
Pulmonic Stenosis Pulmonic (pulmonary) stenosis is a narrowing of the pulmonary valve opening that blocks (obstructs) blood flow from the right ventricle to the pulmonary artery. (msdmanuals.com)
In most children with pulmonary valve stenosis, the valve is mildly to moderately narrowed, making the right ventricle pump a bit harder and at a higher pressure to propel blood through the valve. (msdmanuals.com)
This is the valve separating the right ventricle (one of the chambers in the heart) and the pulmonary artery. (medlineplus.gov)
Classically, this condition is a combination of four defects: 1) a large VSD, 2) narrowing of the exit to the right ventricle (pulmonary stenosis), 3) overdevelopment of the muscular wall of the right ventricle (right ventricular hypertrophy), and 4) the aorta is positioned above the wall separating the two sides of the heart (an overriding aorta).
