Enterococcal Native Tricuspid Valve Endocarditis in Acquired Immunodeficiency Syndrome: A Case Report and Short Review of Literature

Tricuspid valve endocarditis (TVE) is usually reported in individuals with a history of intravenous drug abuse or in those with preexisting structural heart disease. The clinical features of TVE range from acute febrile illness and pleuropulmonary symptoms to refractory right heart failure. We report a case of a 43-year-old acquired immunodeficiency syndrome (AIDS) patient with structurally normal cardiac valves and without any history of parenteral drug abuse or intravascular catheter use, presenting with prolonged fever and progressive dyspnoea, who was subsequently diagnosed with enterococcal tricuspid valve endocarditis. The case report highlights that AIDS should be considered as a differential diagnosis in TVE patients without any etiologies for TVE such as the intravenous-drug user (IVDU), intracardiac device, or structural heart disease including congenital heart disease.
