Objective: The operability evaluation for pulmonary thromboendarterectomy (PEA) in patients with chronic thromboembolic pulmonary hypertension (CTEPH) is always difficult. In this study, we aimed to identify a better indicator of operability in patients with surgically accessible CTEPH lesions.
Methods: Two-hundred-eight patients with surgically accessible CTEPH lesions who underwent PEA at Beijing Anzhen Hospital from March 2001 to February 2014 were retrospectively reviewed. The occluded pulmonary segments (OPS) were assessed by ventilation/perfusion scintigraphy, pulmonary vascular resistance (PVR) was measured by right heart catheterization and the PVR/OPS ratio was calculated.
Results: Seven (3.37%) early deaths occurred in the post-PEA period, six late deaths occurred during the mean follow-up period of 58.3 .. View More»
