Chronic thromboembolic pulmonary hypertension: anticoagulation and beyond

Chronic thromboembolic pulmonary hypertension (CTEPH) is a rare complication in pulmonary embolism (PE) survivors, characterized by chronic vascular occlusion and pulmonary hypertension. The identification and diagnosis of CTEPH requires a stepwise approach, starting with symptom evaluation, functional evaluation, screening imaging, and progressing to interventional hemodynamic assessment. On the backbone of anticoagulation, CTEPH management necessitates a multidisciplinary approach. Surgical pulmonary thromboendarterectomy (PTE) is the only potentially curative option. In nonoperable disease or residual disease after PTE, interventional balloon pulmonary angioplasty and/or pulmonaryvasodilator therapies can be offered, in collaboration with interventional and vascular pulmonary colleagues. As it is a disease that can cause high morbidity and mortality, CTEPH requires a high index of suspicion to diagnose and treat in patients following PE.
