Why the study?
Infected cardiac myxomas are rare clinical presentations that can cause concomitant infective valve endocarditis, requiring prompt diagnosis and treatment to avoid severe complications.
This case report demonstrates that a rare Staphylococcus lugdunensis-infected left atrial myxoma complicated by mitral valve endocarditis and septic emboli can be successfully managed with urgent surgical excision, mitral valve replacement, and a 6-week course of intravenous nafcillin.

Alerts to infected myxoma in atypical endocarditis; leaves open standardized management protocols.
Cardiac myxomas are benign tumors; however, infected myxomas represent a rare clinical presentation. Infected myxomas can cause concomitant infective valve endocarditis, which may lead to complications such as persistent bacteremia, valvular insufficiency/stenosis, and embolic phenomena if not treated promptly. Early diagnosis and treatment, often including antibiotics and urgent surgery, are crucial to prevent severe complications.
