A 23\u2010year\u2010old woman with cerebral infarction due to MMD was referred to our center for MMD bypass surgery and treatment of severe PAH.

We initiated PAH\u2010targeted therapy before MMD bypass surgery, as bypass surgery was considered high\u2010risk in the presence of severe PAH. Despite a positive response to acute vasoreactivity testing with nitric oxide (NO) inhalation, calcium channel blockers were avoided due to the risk of hypotension\u2010induced cerebral ischemia. We initiated endothelin receptor antagonist (macitentan, 10\u2009mg\/day) monotherapy because upfront combination therapy may also cause hypotension. Endothelin receptor antagonist monotherapy improved symptoms and pulmonary hemodynamics, reducing vascular resistance from 11.4 to 7.1 Wood Units after 1 month. Bilateral cerebral bypass surgery was performed after hemodynamic improvement. The clinical spectrum of RNF213\u2010associated PAH may be broader than previously reported.
