Pericarditis bacteriana por Cardiobacterium hominis: un caso clínico inusual

Abstract

The case of a male patient under hemodialytic therapy, who developed right heart failure is presented. Echo cardiography revealed pericardial effusion, constrictive pattern in the right cavities, septation, without valvular damage and preserved systolic and diastolic function. Pericardial drainage and extensive pericardiectomy was performed obtaining cultures of pericardial tissue positive for an HACEK group organism, Cardiobacterium ho minis, with repeatedly negative blood cultures. This is a rare clinical presentation of isolated bacterial pericarditis by an atypical microorganism, without associated endocarditis. The infection mechanisms are presented and the scarce available scientific literature is discussed in this study.
