Four months after elective aortic valve replacement/root enlargement was performed on a young adult, the patient required repeat surgery for a pseudoaneurysm of the ascending aorta and a small perivalvular abscess.Vegetation was noted to be attached to the previously implanted bovine pericardium which had broken down and shriveled into a clump of tissue in the mid anterior wall of the aorta.This bovine graft material was removed, cultured, and grew aspergillus.The source of the aspergillus is suspected to have been introduced from the air during implantation.However, out of an abundance of caution, this report is being submitted.
