Infective endocarditis of a forgotten valve

Abstract

A 62-years-old man with interventricular communication was admitted to the hospital with a 6-month history of constitutional symptoms. The patient was feverish and a grade III/VI continuous murmur was noted in all precordium. Patient’s blood analysis showed elevation of inflammatory markers and bacteriaemia caused by Granulicatella adiacens. Transoesophageal echocardiogram diagnosed infective endocarditis of the aortic valve. The patient completed 3 weeks of antibiotic therapy and was submitted to aortic valve replacement and correction of the interventricular communication. Before hospital discharge, routine transthoracic echocardiogram was done and a pulmonary valve vegetation measuring 6x7 mm, not previously described, was noted, as well as de novo severe pulmonary valve insufficiency. The surgical risk was very high in this patient. Antibiotic therapy was extended and the patient was maintained under close follow-up in appointments. The patient remained asymptomatic and clinically stable.
