Abstract:
A 79-year-old male with a history of ESRD and treated MRSA endocarditis was found to have a recurrence of MRSA bacteremia. He was treated with antibiotics. During his hospitalization, he suddenly developed complete heart block requiring transcutaneous pacing, and subsequently transvenous pacing wires were placed. Transesophageal echocardiography demonstrated pseudo- aneurysm of the mitral-aortic intervalvular fibrosa as well as aortic valve thickening, and a mitral vegetation. Cardiothoracic surgery was consulted to obtain source control, but the patient was deemed to be a poor surgical candidate. While continuing medical therapy and transvenous pacing, the patient developed refractory hypotension, acidosis, and ultimately expired.
