We report a case of a 73-year-old female patient admitted to the surgical department for a splenic abscess. She had a history of a mechanical aortic valve implanted two years earlier. During the diagnostic work-up, the patient underwent a transesophageal echocardiogram that revealed the presence of multiple paravalvular abscesses, establishing the diagnosis of prosthetic valve endocarditis. A few days later, the echocardiogram was repeated due to a new-onset systolic-diastolic murmur. A large

The microbiologic exam revealed the presence of Streptococcus milleri, usually found in the gastrointestinal flora and a known pathogenic agent of endocarditis.
