Nonsurgical treatment of a patient with decompensated right ventricular failure due to chronic thromboembolic pulmonary hypertension with proximal clot location-A case report

Chronic thromboembolic pulmonary hypertension (CTEPH) is a disease resulting from impaired patency of the pulmonary arteries by a clot, and the treatment method of choice is pulmonary endarterectomy (PEA). In inoperable patients, balloon pulmonary angioplasty (BPA) is recommended, but we need to implement pharmacological bridge therapy to BPA in some cases. We report a case of a 38-year-old male diagnosed with CTEPH, disqualified from PEA due to comorbidity, who developed right ventricular (RV) failure. The case shows a complex pharmacological treatment method that can be successfully used as an effective bridge therapy to BPA in patients with CTEPH and severe RV dysfunction, disqualified from surgery.
