Angiodysplasia are common in patients over the age of 60. Heyde syndrome 
describes the coincidence of aortic valve stenosis and gastrointestinal bleeding 
from angiodysplasia. We describe one characteristic case of aortic valve 
stenosis and gastrointestinal bleeding from angiodysplasia which subsided after 
replacement with an aortic valve bioprosthesis. We review the current literature 
and discuss the actual explanation approaches for this phenomenon.
CONCLUSION: There seems to be a clear indication for valve replacement in the 
case of aortic valve-stenosis and gastrointestinal bleeding due to 
angiodysplasia.
