Abstract

Background: Isolated pulmonary valve endocarditis (PVE) is an extremely uncommon clinical finding comprising less than 1.5-2% of cases for infective endocarditis. It is a challenging condition to diagnose mainly because of nonspecific signs and symptoms at presentation.

Case Presentation: A 58-year-old married and retired man was admitted to a community hospital for evaluation of chest pain. Transesophageal echocardiography (TEE), 2 days after, revealed semi-mobile vegetation on the pulmonary valve and pulmonary artery wall. Moreover, occlude devices at the root of the aorta, and the pulmonary artery was seen. Left ventricular ejection fraction (LVEF) with systolic dysfunction, mild aortic insufficiency (AI), mild tricuspid regurgitation (pulmonary artery pressure of 50 mmHg) without pericardial effusion, was also reported in the Echocardiography. Blood cultures, viral markers, and Brucella IgG and IgM titration were negative during the admission. The patient received a 4-week course of intravenous antibiotic therapy, including Ceftriaxone and Teicoplanin (Targocid).
