Definition

Noun: A congenital heart defect characterized by an abnormal narrowing of the pulmonary valve or the adjacent area of the pulmonary artery. This stenosis (narrowing) obstructs the normal flow of blood from the right ventricle of the heart to the lungs.

Usage

Pulmonary stenosis is a medical term used specifically to describe a type of heart condition. It is typically used in clinical, diagnostic, and patient education contexts. - The cardiologist diagnosed the infant with pulmonary stenosis. - Pulmonary stenosis can range in severity from mild to severe.

Examples

• The echocardiogram confirmed the presence of pulmonary stenosis.
• Surgery is often recommended for critical pulmonary stenosis.
• In many cases, pulmonary stenosis is present at birth (congenital).

Advanced Usage

• Valvular pulmonary stenosis: Specifies that the narrowing is located precisely at the pulmonary valve itself, which is the most common form.
• Subvalvular (infundibular) pulmonary stenosis: Refers to a narrowing in the outflow tract of the right ventricle, just below the pulmonary valve.
• Supravalvular pulmonary stenosis: Indicates a narrowing in the pulmonary artery itself, above the valve.

Variants and Related Words

• Pulmonary valve stenosis: A more precise synonym often used interchangeably with .
• PS: A common medical abbreviation.
• Stenosis (noun): The general condition of abnormal narrowing in a blood vessel or other tubular organ or structure.
• Congenital heart defect (noun phrase): The broader category of heart conditions present at birth, which includes pulmonary stenosis.

Synonyms

• Pulmonary valve stenosis
• Right ventricular outflow tract obstruction (RVOTO) (This is a broader term that can include pulmonary stenosis)

Related Phrases

• Balloon valvuloplasty: A common non-surgical procedure to treat pulmonary stenosis by using a catheter with a balloon to widen the narrowed valve.
• Right ventricular hypertrophy: A condition where the muscle of the right ventricle thickens, which can be a consequence of severe pulmonary stenosis as the heart works harder to pump blood through the narrow opening.

Noun

1. abnormal narrowing of the opening into the pulmonary artery from the right ventricle
