Abstract
Pulmonary thromboendarterectomy (PTE) surgery is an effective treatment for the majority of patients with chronic thromboembolic pulmonary hypertension (CTEPH), with an acceptable mortality rate. The immediate outcome after PTE has repeatedly shown a dramatic decline in pulmonary vascular resistance, echocardiographic evidence of reduced right heart pressure, and increased perfusion on lung scan. Prospective long-term follow-up studies (1 to 4 years post-PTE) have found most patients to be in New York Heart Association class I or II, with significantly improved quality of life and ability to walk, climb stairs, return to work, and perform household tasks. Disease-related symptoms and hospitalizations and/or emergency room visits have also been significantly reduced. These findings indicate an improved functional status and longer life expectancy can be achieved after PTE.
