According to the Fifth World Symposium on Pulmonary Hypertension that convened in 20132:
All patients diagnosed with CTEPH should receive lifelong anticoagulation
Comparing radiographic burden of disease with hemodynamics is critical to determining operability and risk from surgery before performing pulmonary thromboendarterectomy (PTE) (also called pulmonary endarterectomy [PEA])
Overall operability assessment must consider patient factors, including comorbidities
Operability assessment remains a subjective process, so reevaluation of operability by a second experienced CTEPH center in cases initially deemed inoperable is recommended.2
