Echocardiographic Features of an Evolving Periaortic Valvular Abscess in a Patient with Staphylococcus Epidermidis Prosthetic Valve Endocarditis.

Prosthetic valve endocarditis is a serious complication following valve replacement surgery, with the development of aortic root abscess being a catastrophic manifestation. We present a case of a 71-year-old female with a bioprosthetic aortic valve who presented with shortness of breath. Echocardiographic findings revealed vegetation on the prosthetic aortic valve with a periaortic, annular abscess. Given the patient's comorbidities and high surgical risk, conservative management with antibiotics was chosen. The patient responded well to antibiotic therapy and was discharged with long-term antibiotic treatment. Prosthetic valve endocarditis, particularly with periaortic abscess formation, is associated with significant morbidity and mortality. Early diagnosis and appropriate management are crucial for improving outcomes.
