A congenital heart defect characterized by obstruction or narrowing of the valve between the right ventricle and the pulmonary artery.
A condition in which the opening to the pulmonary artery in the right ventricle becomes narrow.
Congenital narrowing of the outlet of the right ventricle of the heart to the pulmonary artery. The defect may be in the pulmonary valve (valvular stenosis) or in the outflow tract of the right ventricle below the valve {infundibular stenosis). It may be isolated or combined with other heart defects (e.g. tetralogy of Fallot). Severe pulmonary stenosis may produce angina pectoris, faintness, and heart failure. The defect is corrected by surgery.
A disorder of the heart with obstruction of the outflow of blood from the right ventricle. Narrowing of the pulmonary valve at the exit of the right ventricle and narrowing of the pulmonary artery may cause obstruction. The condition is usually congenital, although it may be caused by rheumatic fever. In the congenital condition, pulmonary stenosis may occur with other heart defects and is then known as Fallot’s tetralogy. Breathlessness and enlargement of the heart and eventual heart failure may be the consequence of pulmonary stenosis. Surgery is usually necessary to remove the obstruction.
Narrowing of the opening into the pulmonary artery from the right cardiac ventricle.
A cardiac ailment characterized by hindered blood outflow from the right ventricle (lower heart chamber), necessitating the heart to exert more effort to propel blood to the lungs.
The constriction could arise due to the pulmonary valve narrowing at the ventricular exit, the pulmonary artery’s narrowing responsible for carrying blood to the lungs, or a narrowing of the upper segment of the ventricle.
Pulmonary stenosis is generally a congenital condition and can manifest either independently or in conjunction with a cluster of heart abnormalities known as the tetralogy of Fallot. In uncommon instances, stenosis might emerge later in life, often as a consequence of rheumatic fever, and potentially lead to heart failure symptoms.
Detecting pulmonary stenosis is accomplished through a combination of diagnostic methods such as chest X-ray, ECG, echocardiography, and Doppler ultrasound scanning. Narrowing might be alleviated using a balloon catheter. For more severe instances, successful outcomes are often achieved through heart valve surgery or various forms of open heart surgery.
