[Balloon pulmonary angioplasty in chronic thromboembolic pulmonary hypertension:a paradigmatic case report].

Chronic thromboembolic pulmonary hypertension (CTEPH) is a complex disease where organized pulmonary thrombi and progressive vascular remodeling of the pulmonary arterial tree act synergistically to increase pulmonary vascular resistance and cause pulmonary hypertension. Balloon pulmonary angioplasty (BPA) has gained a renewed interest for the treatment of patients with CTEPH who are not undergoing surgery with pulmonary endarterectomy (PEA) or with persistent/recurrent pulmonary hypertension after PEA and has shown promising results in several observational studies conducted to date. We describe the case of a 42-year-old man with inoperable CTEPH in NYHA functional class III who normalized functional capacity, hemodynamic profile and main hemodynamic parameters after three BPA sessions.
