Pulmonary valve stenosis
Pulmonary Valve Stenosis
Pulmonary valve stenosis (PVS) (pronunciation: pul-MO-nary VALV steh-NO-sis) is a condition characterized by an obstruction in the blood flow from the right ventricle of the heart to the pulmonary artery. This obstruction is caused by narrowing (stenosis) of the pulmonary valve, which controls the flow of blood from the heart to the lungs.
Etymology
The term "pulmonary" is derived from the Latin pulmonarius, meaning "of the lungs". "Valve" comes from the Latin valva, meaning "leaf of a door". "Stenosis" is derived from the Greek stenos, meaning "narrow".
Symptoms
Symptoms of pulmonary valve stenosis can vary greatly depending on the severity of the condition. They may include shortness of breath, chest pain, fatigue, and syncope (fainting). In severe cases, PVS can lead to right ventricular hypertrophy (enlargement of the right ventricle) and heart failure.
Diagnosis
Pulmonary valve stenosis is typically diagnosed through a combination of physical examination, echocardiogram, and cardiac catheterization. The echocardiogram is particularly useful in visualizing the structure of the heart and assessing the severity of the stenosis.
Treatment
Treatment for pulmonary valve stenosis depends on the severity of the condition. Mild cases may simply be monitored, while more severe cases may require balloon valvuloplasty or valve replacement surgery.
