Infected cardiac myxoma is a rare condition with a high risk of arterial embolization, highlighting the need for early diagnosis and urgent surgical resection.
Documents S. mitis superinfection in cardiac myxoma; hypothesis-generating for embolization risk and resection timing in this rare entity.
A 66-year-old male presenting with low-grade fever and general fatigue was diagnosed as having infected myxoma of the left atrium. Blood cultures grew Streptococcus mitis. He underwent urgent resection and histological examination revealed tumor cells in a mucopolysaccharide matrix and bacterial colonies along with active inflammation. Infected cardiac myxoma is extremely rare; however, it contains a potential risk of arterial embolization and so early diagnosis and urgent surgery should be considered.
