Pulmonary arterial hypertension (PAH) with coexisting portal hypertension has been defined as portopulmonary hypertension (PPHTN). It is often related to liver cirrhosis of various aetiologies and is associated with a high mortality rate. Endothelin‐1 (ET) is supposed to play an important role in the pathogenesis of PAH as well as portal hypertension. Therefore, therapy with an ET A /ET B receptor antagonist might be of use in the treatment of PPHTN. We report the case of a 76‐year‐old male with liver cirrhosis owing to chronic hepatitis C virus infection and PPHTN who was treated with the dual ET A /ET B receptor antagonist bosentan. The patient showed remarkable improvement of 6‐min walking distance from 300 to 480 m after 2 weeks and to 540 m after 14 weeks, respectively. In addition, a significant decline of N‐terminal pro B‐type natriuretic peptide fraction (NT‐proBNP) from 4928 ng mL −1 to 640 ng mL −1 was observed. Bosentan might be a promising new therapeutical option for patients suffering from PPHTN.
