Synopsis

Increased resistance to pulmonary blood flow caused by narrowing within the right ventricular outflow tract, pulmonic valve, or pulmonary artery. Causes include congenital abnormality, rheumatic heart disease, carcinoid disease, and stenosis of prosthetic valves placed for surgical correction of complex congenital disease. More severe cases of congenital disease are typically diagnosed in infancy. Mild cases may remain asymptomatic or be diagnosed later in life due to progressive worsening of the disease. Presenting symptoms may include dyspnea, fatigue, right ventricular failure, and cyanosis. Systolic ejection click and systolic ejection murmur may be heard on exam.

Mild cases may not require treatment. Otherwise, treatment is surgical.
