Abstract

Infective endocarditis of the pulmonary valve (PVIE) is an uncommon condition in adults whose clinical presentation often mimics pneumonia, leading to delayed recognition. A 38-year-old man without classic risk factors presented with fever and dyspnea and was initially treated as pneumonia without clinical improvement. Computed tomography pulmonary angiography revealed septic pulmonary emboli, and echocardiography demonstrated vegetation on the pulmonary valve with severe regurgitation. Blood cultures were negative. Due to the progression of vegetation size and clinical deterioration, pulmonary valve replacement was performed, with a favorable outcome. PVIE is difficult to diagnose because its presentation often resembles pneumonia, requiring a high index of clinical suspicion. Its clinical course is variable; large or progressive vegetations and significant valvular regurgitation constitute the main indications for surgical intervention. Early clinical suspicion and a multidisciplinary approach allow for timely diagnosis and improved prognosis.
