Abstract
Chronic thromboembolic pulmonary hypertension (CTEPH) is classified as Group-4 pulmonary hypertension caused by organized thrombi in pulmonary arteries. Pulmonary endarterectomy (PEA) has been shown to improve the symptoms and prognoses of patients with proximal CTEPH. The soluble guanylate cyclase stimulator (riociguat) is the sole FDA-licensed drug for the treatment of CTEPH, and guidelines recommend its use for patients with inoperable CTEPH or residual or recurrent pulmonary hypertension following PEA. Balloon pulmonary angioplasty (BPA) is a new procedure, but it is a promising alternative to PEA, especially in patients with inoperable CTEPH. This review summarizes the history, indications, procedures and complications of BPA. Finally, we discuss the future perspective of BPA for better management of CTEPH.
