Pulmonary stenosis is a cardiovascular condition characterized by the narrowing or constriction of the pulmonary valve, the gateway between the right ventricle of the heart and the pulmonary artery. This narrowing impedes the smooth flow of blood from the heart to the lungs, placing increased strain on the right ventricle. Commonly a congenital defect, pulmonary stenosis varies in severity, with symptoms ranging from mild to severe. Individuals with mild cases may remain asymptomatic for years, while severe cases can lead to symptoms such as chest pain, fatigue, and fainting. Timely diagnosis and intervention, often through surgical procedures or balloon valvuloplasty, are crucial for managing pulmonary stenosis and preventing complications. Regular medical monitoring is essential to ensure optimal heart function and overall well-being for individuals affected by this condition.
