Allergy to Galactose-Alpha-1,3-Galactose is an allergy to mammalian proteins, that are present on the surface of standard bioprosthestic valves, and could result in a catastrophic allergic reaction or may cause early deterioration of the bioprostheses. Aortic homograft is an acceptable alternative to standard prosthetic valves (biological and mechanical) to avoid a potential allergic manifestation and the need for definitive oral anticoagulation. We report the implantation of an aortic homograft in a patient with an aortic stenosis who presents a documented AlphaGal allergy.
