Eustachian Valve Endocarditis Secondary to Candida glabrata Complicated by Frailty and Acute COVID-19 Infection

Transesophageal echocardiograms have revealed that the eustachian valve persists in a small proportion of the adult population. Only a few cases of eustachian valve endocarditis have previously been reported in older adults. This case report describes an 82-year-old male patient with eustachian valve endocarditis. He had a remote history of infrarenal abdominal aortic aneurysm post endovascular leak repair, recent septicemia from <i>Streptococcus mitis</i> from an infected tooth, frailty, diabetes, and immunosenescence. He was found to have developed bacteremia and fungemia.
