Infective endocarditis; Cardiac resynchronization
A 71-year-old man who underwent cardiac resynchronization therapy with a defibrillator (CRT-D) implantation five years ago, was admitted by a lengthy febrile illness. An initial transthoracic echocardiogram identified a unique vegetation of 10 mm adhered to device cables. Triple antibiotic was started with initial favorable clinical response, but the control transesophageal echocardiogram (TEE) at ten days showed several large mobile vegetations adhered to CRT-D leads and partially occupying the tricuspid annulus (A-B). Three-dimensional TEE confirmed these findings (C). Accordingly, emergent cardiac surgery for device removal was indicated (D). The patient died within 48 hours because of septic multiple organ dysfunction syndrome.
