A 52-year-old man presented to the emergency department with externalization of a biventricular implantable cardioverter defibrillator (Figure 1). He had been admitted six months earlier with a fistula surrounding the device but left the hospital against medical advice before treatment. At admission to the emergency room his heart rate was 105 beats/min and his blood pressure was 122/96 mmHg. Cardiac auscultation revealed a systolic murmur at the apex; there were no breath sounds at the right lung base and lower limb edema was observed.
Three sets of blood cultures were drawn before antimicrobial therapy with vancomycin was begun. Methicillin-resistant Staphylococcus aureus was subsequently isolated. Transthoracic and transesophageal echocardiography were performed and a mass was seen adhering to the lead (Figures 2 and 3). Complete device and lead removal was performed within two days. The patient received parenteral antimicrobial therapy for four weeks and a new device was implanted on the contralateral side before discharge.
