 In this study, researchers examined the outcomes of pulmonary endarterectomy, PA, among patients with chronic thromboembolic pulmonary hypertension, TEF. They found that 89% of patients experienced residual pulmonary hypertension symptoms within three months of their surgery, suggesting that many patients are not receiving adequate follow-up care. Additionally, they observed a significant increase in a number of diagnostic tests performed by patients after the approval of riosiguate, which suggests that physicians have become more aware of the possibility of persistent orecurrent TEF post-PA.
