Aortic root abscess – a deadly complication of UTI-induced infective endocarditis

Abstract

Aortic root abscess and endocarditis should be suspected in patients with bradycardia and sepsis. We present a case of a 76 year old male who presented with urinary tract infection and sepsis and developed bradycardia and ventricular stand still during hospital admission. Transthoracic echocardiogram was unrevealing; transesophageal echocardiogram showed prosthetic valve dehiscence and aortic root abscess, intracardiac fistula, and tricuspid valve endocarditis. This case highlights the importance of suspecting endocarditis in patients with sepsis and known source of infection, especially if blood cultures do not clear or conduction abnormalities develop.
