Abstract:
Chronic thromboembolic pulmonary hypertension occurs when acute thromboemboli fail to dissolve completely. The resulting fibrotic scar tissue within the pulmonary arteries is obstructive and eventually leads to right heart failure. Medical therapy for this condition is supportive, but surgery with pulmonary artery endarterectomy is curative, and carries a low mortality at experienced centers.
