Abstract:
We report the case of a 63-year-old man with ischemic cardiomyopathy having an implantable cardioverter defibrillator (ICD) implanted for repeated ventricular tachycardia (VT). After several revisions of the ICD lead, a thrombosis of the left venous system was diagnosed. A right pectoral ICD device was implanted, and a sufficient defibrillation threshold (DFT) could not be achieved during the operation. Thus, a further defibrillation lead was implanted into the coronary sinus, which successfully terminated ventricular fibrillation.
