Since the 4th world symposium on pulmonary hypertension (PH), chronic thromboembolic pulmonary hypertension (CTEPH) was assigned an own group in the classification of HP, the group 4. PH is a hemodynamic state defined by a mean pulmonary artery pressure (mPAP) equal to or greater than 25 mmHg at rest, measured by right heart catheterization (CCD). CTEPH is developped by the presence of an obstruction in the pulmonary arteries due to incomplete resolution of pulmonary thromboembolic event leading to pulmonary vascular remodeling after three months of effective anticoagulation. Since the 5th World Symposium HP, CTEPH was assigned an independent working group. The objective of this paper is to update the epidemiological data, pathophysiology, clinical features and treatment of this group of pulmonary hypertension.
