Abstract:
Streptococcus pneumoniae is a rare cause of infectious endocarditis. Most cases have an acute and aggressive evolution, with a high mortality rate. We report the case of a 36-year-old man, with a history of unrepaired ventricular septal defect, who came to the emergency department with fever, cough and asthenia with 3 months of evolution. Blood cultures were positive for Streptococcus pneumoniae Echocardiogram showed large vegetation on septum, free wall and outflow tract of the right ventricle. Thoracic CT revealed septic pulmonary embolism. Antimicrobial therapy and surgical treatment was performed and the patient presented a favourable evolution.
