All of the following are true about airway hemorrhages in Eisenmenger syndrome except:

Correct answer: c) More likely while descending a mountain

In Eisenmenger syndrome airway hemorrhages have to be thought of specially when moving from lower to a higher altitude as during air travel or while ascending a mountain. Hemoptysis has been reported as a cause of death in Eisenmenger syndrome in 11-29% [1].

Defects in hemostatic mechanism due to abnormal platelet function, thrombocytopenia, deficiencies of clotting factor as well as depletion of von Willebrand factor may also contribute to airway hemorrhages in Eisenmenger syndrome [2].
