Hypertension pulmonaire postembolique

PEA remains the treatment of choice for eligible patients. Nevertheless, there is a need to conduct randomized trials to assess the efficacy of novel medical therapies in some situations: (1) in inoperable CTEPH due to distal lesions, (2) before PEA (therapeutic bridge) in patients who are considered “high risk” due to extremely poor hemodynamics, (3) in patients with persistent pulmonary hypertension after surgery.
