Pulmonary stenosis

Pulmonary stenosis is a heart condition characterized by the narrowing of the pulmonary valve, which is responsible for controlling the flow of blood from the right ventricle to the pulmonary artery. This condition can be present at birth (congenital) or can develop later in life.

Symptoms

The symptoms of pulmonary stenosis can vary greatly depending on the severity of the condition. Some individuals may not experience any symptoms, while others may experience shortness of breath, chest pain, fatigue, and fainting. In severe cases, pulmonary stenosis can lead to heart failure.

Causes

Pulmonary stenosis is most commonly a congenital condition, meaning it is present at birth. It is often associated with other heart defects, such as Tetralogy of Fallot. The exact cause of congenital pulmonary stenosis is unknown, but it is believed to be related to genetic factors.

Diagnosis

Pulmonary stenosis is typically diagnosed through a physical examination and imaging tests, such as an echocardiogram. Other tests that may be used include a chest X-ray, MRI, or cardiac catheterization.

Treatment

The treatment for pulmonary stenosis depends on the severity of the condition. Mild cases may not require treatment, while moderate to severe cases may require medication or surgery to widen the pulmonary valve.
