Pulmonary stenosis: ejection systolic murmur, loudest at pulmonary area, radiates to left shoulder; caused by congenital syndromes, rheumatic fever, carcinoid syndrome; features include prominent ‘a waves’ in JVP, widely split S2.
Pulmonic stenosis (PS) is narrowing of the pulmonary outflow tract causing obstruction of blood flow from the right ventricle to the pulmonary artery during systole. Most cases are congenital; many remain asymptomatic until adulthood. Signs include a crescendo-decrescendo ejection murmur. Diagnosis is by echocardiography.
Pulmonary valve stenosis symptoms may include: A whooshing sound called a heart murmur that can be heard with a stethoscope. Fatigue. Shortness of breath, especially during activity. Chest pain. Fainting. Babies with pulmonary valve stenosis may have blue or gray skin due to low oxygen levels.
Valvular pulmonary stenosis: Isolated pulmonary valve stenosis is a condition in which the pulmonary valve is affected by varying degrees of fibrosis, thickening, and commissural fusion, leading to restricted blood flow. This condition is typically congenital and is diagnosed in pediatric patients.
Pulmonic valve stenosis is characterized as an early systolic click with a harsh systolic crescendo-decrescendo ejection murmur, best heard at the left upper sternal border. Unlike aortic stenosis, this murmur will not radiate to the carotids.
Pulmonary stenosis, which is rare among adults, is usually caused by a birth defect, also called a congenital heart defect. Moderate to severe PS is most often diagnosed during childhood due to the loud heart murmur associated with the condition.
The heart murmur of pulmonary stenosis is a choppy noise caused by ejection of blood through the obstructed valve. There is often an associated click sound when the thickened valve snaps to its open position.
Pulmonic (pulmonary) stenosis is a narrowing of the pulmonary valve opening that blocks (obstructs) blood flow from the right ventricle to the pulmonary artery. It is often present at birth (congenital) and thus affects children.
Pulmonary valve stenosis is often diagnosed in childhood. But it may not be detected until later in life. A health care provider uses a stethoscope to listen to the heart. A whooshing sound, called a heart murmur, may be heard. The sound is caused by choppy blood flow across the narrowed valve. Tests to diagnose pulmonary valve stenosis include:
Pulmonary stenosis is mostly congenital. Symptoms range from none to profound cyanosis and the potential for sudden death. Systolic ejection murmur is present and is loudest over left upper sternal border. Cyanotic patients are treated with oxygen and prostaglandin E1 prior to diagnostic testing.
