Supravalvular Pulmonary Stenosis

Supravalvular Pulmonary Stenosis (SPS) is a heart condition that affects the pulmonary artery, leading to a narrowing of the vessel. This article aims to provide a clear and accessible overview of SPS, covering its types, causes, symptoms, diagnostic tests, treatments, drugs, and surgical options.

Types of Supravalvular Pulmonary Stenosis:

1. Branch Stenosis: Narrowing occurs in the branches of the pulmonary artery.
2. Main Pulmonary Artery Stenosis: The main pulmonary artery experiences constriction.
3. Supravalvular Stenosis: Narrowing takes place just above the pulmonary valve.

Common Causes of Supravalvular Pulmonary Stenosis:

Understanding the causes can shed light on preventive measures and potential risk factors.

1. Genetic Factors: SPS can be inherited genetically, with certain genes contributing to its development.
2. Williams Syndrome: A genetic disorder that increases the risk of SPS.
3. Elastin Gene Mutations: Alterations in the elastin gene can lead to the development of SPS.
4. Inflammation: Infections or inflammatory conditions may contribute to the narrowing of the pulmonary artery.
5. Birth Defects: Congenital anomalies during fetal development can result in SPS.
6. Environmental Factors: Exposure to certain environmental toxins during pregnancy may increase the risk.
7. Premature Birth: Babies born prematurely might be more susceptible to SPS.
8. Low Birth Weight: Babies with low birth weight may have an elevated risk.
9. Family History: A family history of SPS increases the likelihood of its occurrence.
10. Complications from Surgery: Some heart surgeries may inadvertently lead to the development of SPS.
11. Injury to the Pulmonary Artery: Trauma or injury to the pulmonary artery can cause narrowing.
12. Blood Clots: Clots in the pulmonary artery can contribute to stenosis.
