Pulmonary Valve Stenosis: From Diagnosis to Current Management Techniques and Future Prospects

PS is mostly a congenital disease, but it can also develop later in life due to other medical conditions. The severity of the stenosis can vary widely, ranging from mild to severe and potentially life-threatening. Although it is primarily a disease of childhood, its sequelae have become increasingly prevalent in the adult population due to improvements in diagnosis and treatment. One of the most significant advances in the treatment of PS is the development of percutaneous procedures and devices that can correct the condition without surgical intervention. This approach has proven to be effective and less invasive, offering patients a safe and efficient option for managing their condition.

Problem: Pulmonary Valve Stenosis

It’s most commonly the result of a congenital heart defect. However, rarely PS can develop as a result of infections such as rheumatic fever (PDF)(link opens in new window) or carcinoid syndrome.

Pulmonary atresia

Pulmonary atresia (PA) is a rare congenital abnormality of heart development where the pulmonary valve that controls blood flow from the right side of the heart to the lungs doesn’t form (atresia).

Pulmonary Valve Stenosis

In most cases, the cause isn't known. It's a common type of heart defect. Babies born to mothers who had rubella (German measles) during pregnancy were more likely to develop pulmonary stenosis along with deafness and patent ductus arteriosus. Some patients can have other heart defects along with PS.

Pulmonary Valve Stenosis (Tetralogy of Fallot)

This condition occurs as part of a group of heart defects called tetralogy of Fallot, including a ventricular septal defect and, often, an abnormal pulmonary artery.

Pulmonary valve stenosis in the adult patient: pathophysiology, diagnosis and management

The most common form of right ventricular outflow tract (RVOT) obstruction is pulmonary valve stenosis. Pulmonary stenosis (PS) occurs in isolation in 8%–10% of congenital heart disease but is often associated with other congenital lesions1 Subvalvar and supravalvar PS are less common but also seen in adults.

The syndrome of pulmonary stenosis with patent foramen ovale

Pulmonary stenosis with patent foramen ovale is characterized by chronic cyanosis, polycythemia and clubbing. In the degree of cyanosis it occupies an intermediate place between the tetralogy of Fallot and the Eisenmenger syndrome. Pulmonary stenosis with closed septa is essentially a noncyanotic lesion. On the basis of cyanosis, cases of pulmonary stenosis with and without patency of the foramen ovale are placed in different classes of congenital heart disease. Otherwise these two diseases are clinically and pathologically very similar and differ from the tetralogy of Fallot in important respects.

When Your Child Has Pulmonary Stenosis (PS)

Most children with an isolated PS will not have symptoms. The murmur may be heard during childhood as part of a well child exam or another visit. Children with mild or moderate PS often have no symptoms.

Pulmonary or pulmonic stenosis is a common congenital heart defect that involves mild, moderate, or severe narrowing of the right ventricular outflow tract, pulmonary valve, or pulmonary arteries, which restricts blood flow from the heart to the lungs. Pulmonary stenosis can occur alone or in combination with other congenital heart defects.
