A 60-year-old man presenting with systemic embolism and heart failure was diagnosed with non-bacterial thrombotic endocarditis following open chest surgery for a right atrial mass.
Case Report (n=1)
No
This case demonstrates that non-bacterial thrombotic endocarditis can present atypically as a right atrial mass with biventricular lesions, underscoring the need to investigate for multiple underlying conditions such as cancer and antiphospholipid syndrome when blood cultures are negative.
Non-bacterial thrombotic endocarditis (NBTE) is a condition that results in the development of vegetation on cardiac valves that are devoid of inflammation and bacteria. We herein report a 60-year-old man who transferred to our hospital because of a systemic embolism and heart failure. A mass in the right atrium and vegetation on the mitral valve were observed. He was first diagnosed with infectious endocarditis according to the Duke criteria. During treatment, however, the patient was diagnosed with antiphospholipid syndrome and cancer. After 4 weeks of antibacterial therapy, the patient underwent open chest surgery, and the postoperative histological diagnosis was NBTE.
