title: Listeria endocarditis causing aortic root abscess and a fistula to the left atrium.
abstract: We report the case of a 74-year-old man who presented with endocarditis on a porcine aortic valve replacement. Five of six blood cultures grew listeria monocytogenes. Transoesophageal echocardiography demonstrated the presence of a cavity posterior to the aortic annulus, apparently communicating with the left atrium. The patient underwent successful aortic valve re-replacement. Listeria endocarditis is rare with only 58 reported cases in the literature and is associated with high mortality.
