The influence of alpha-gal allergies on cardiothoracic surgery is largely unknown. Allergic responses to galactose-alpha-1, 3-galactose, or “alpha-gal”, are due to antibodies against non-primate mammalian proteins and are mediated by IgE. This allergy has only recently been discovered and is increasingly prevalent, upwards of 20%-25% of the general population in the southeast United States is sensitized to alpha-gal. Due to the exposure of patients to significant amounts of alpha-gal containing heparin during the course of cardiopulmonary bypass, this allergy may have significant implications for patients undergoing cardiac surgery. We provide a four case series from a single institution detailing successful cardiac surgery in four patients with known alpha gal allergies. These cases demonstrate that pre-treatment with diphenhydramine and steroids may help attenuate serious allergic reactions and allow cardiac surgery to be performed more safely.
