Pulmonary valve stenosis

Pulmonary valve stenosis is a heart valve disorder in which outflow of blood from the right ventricle of the heart is obstructed at the level of the pulmonic valve. This results in the reduction of flow of blood to the lungs. Valvular pulmonic stenosis accounts for 80% of right ventricular outflow tract obstruction. While the most common cause of pulmonary valve stenosis is congenital heart disease, it may also be due to rheumatic heart disease or a malignant carcinoid tumor. Both stenosis of the pulmonary artery and pulmonary valve stenosis are causes of pulmonic stenosis. Symptoms include jugular vein distension, cyanosis (usually visible in the nailbeds), right ventricular hypertrophy and general symptoms of lowered oxygenation of...
