First quantification of alpha‐<scp>G</scp>al epitope in current glutaraldehyde‐fixed heart valve bioprostheses

Abstract

For the first time, the quantitative evaluation of the αGal epitope in heart valve bioprostheses, already in clinical practice for about 40 yrs, was finally determined. Such quantification might provide indications of biocompatibility relevant for the selection of bioprosthetic devices and an increase in the confidence of the patient. It might become a major quality control tool in the production and redirection of future investigation in the quest for αGal-free long-lasting substitutes.
