RESUMO
A 28-year-old woman with patent foramen ovale who developed tricuspid valve infective endocarditis with complications of multiple infarctions and abscesses was treated surgically. The patient was transferred to our institution because of fever and joint pain. Echocardiography revealed a large vegetation (25 mm) on the tricuspid valve and a patent foramen ovale. Computed tomography and magnetic resonance imaging showed cerebral infarctions, multiple lung abscesses, and vertebral osteomyelitis. <i>Staphylococcus epidermidis </i>was identified in blood cultures. After treatment with adequate antibiotics for 5 weeks, the patient underwent surgical resection of the vegetation followed by tricuspid valve repair and direct closure of the patent foramen ovale. Antibiotic therapy was continued postoperatively, and the patient was discharged 7 weeks after the operation. No further endocarditis or embolism has occurred. In cases of right-sided endocarditis with systemic embolism and abscesses, the presence of a patent foramen ovale should be considered, and appropriate timing of the operation should be determined to prevent further systemic embolization of the vegetation.
