A Case of Concurrent Tricuspid Valve, Mitral Valve, and Device Endocarditis.

Endocarditis involving multiple valves is a relatively rare phenomenon, and much about its etiology, prognosis, and best practices for treatment remains uncharacterized. Currently, the treatment of multiple-valve endocarditis is similar to that of single-valve endocarditis. However, limited data suggest that patients may potentially benefit from different treatment approaches not yet clearly defined. Here, we present a unique case of a 22-year-old female with a history of aortic coarctation repair and a ventricular septal defect (VSD) patch repair who presented to the emergency department (ED) after acute onset of fever, chills, nausea, vomiting, and diarrhea. The patient was admitted to the ICU with septic shock and was found to have concurrent mitral valve, tricuspid valve, and VSD patch endocarditis. We discussed her hospital course and treatment as well as current treatment approaches to multiple-valve endocarditis.
