Purpose Of Review:
The present review provides an update on treatment of chronic thromboembolic pulmonary hypertension (CTEPH), a rare form of pulmonary hypertension characterized by precapillary pulmonary hemodynamic parameters with chronic thrombotic occlusion of the pulmonary vasculature.
Recent Findings:
Pulmonary thromboendarectomy (PTE) remains the recommended treatment for patients with surgically accessible disease. Recent data suggest that patients preoperatively bridged with medical therapy may have improved outcomes but further research is needed. Riociguat improves hemodynamics, right ventricular function, quality of life, and functional capacity and is the drug of choice for patients with inoperable/persistent disease. Recently published data suggest that endothelin receptor blockers and treprostinil may also have a role in medical management of this patient population. A growing body of evidence indicates that in experienced centers balloon pulmonary angioplasty (BPA) may be a well tolerated and effective adjunct to pharmacological treatment for patients with inoperable disease affecting subsegmental vasculature.
Summary:
Untreated CTEPH carries significant morbidity and mortality. Recent publications provide a wealth of data on safety and efficacy of BPA for inoperable subsegmental disease, but its precise fit in the treatment algorithm, both pharmacological and procedural, requires further investigation. PTE remains the procedure of choice for surgically accessible disease.
