The impact of right ventricular energy failure on the results of pulmonary endarterectomy and balloon pulmonary angioplasty in patients with chronic thromboembolic pulmonary hypertension

Objective: We aimed to investigate the effect of right ventricular energy failure (RVEF) on hemodynamic and clinical outcomes in patients diagnosed with chronic thromboembolic pulmonary hypertension (CTEPH) undergoing pulmonary endarterectomy (PEA) surgery or balloon pulmonary angioplasty (BPA). Patients and Methods: A total of 100 CTEPH patients planned for PEA or BPA were included in the study. Based on the presence of RVEF during diagnosis, patients divided into two groups. Hemodynamic data from right heart catheterization (RHC) were compared before and after procedures in 3-6 months follow up period. Results: Patients with RVEF revealed a decrease in mean pulmonary artery pressure (mPAP) from 54.67±12.27 mmHg to 36.12±11.76 mmHg (p:
