Objective: to describe a rare case of infective endocarditis (IE) with isolated localization in the pulmonary valve (PV).Materials and methods. We observed primary IE with isolated localization in the PV in a 27-year-old female patient without risk factors of right-side IE.Results. The disease was caused by Streptococcus gordonii and proceeded acutely with typical signs of right-side IE: fever above 38 °С, chills, clinical picture of bilateral septic embolic abscess pneumonia, as well as secondary anemia, secondary thrombocytopenia, and glomerulonephritis. Echocardiography showed large vegetations in the PV prolapsing in the right ventricle and pulmonary artery.Conclusion. IE with localization in the PV should be suspected in patients with fever and clinical picture of septic embolic pneumonia in absence of other embolic situations.
