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 Streptococcus mitis from an infected tooth, frailty, diabetes, and immunosenescence. He was found to have developed bacteremia and fungemia.
