[Total intravenous anesthesia for repositioning an implantable defibrillator in a patient with long QT syndrome].
We report the case of a 27-year-old woman with congenital long QT syndrome (LQTS) who was scheduled for surgery to reposition an implantable defibrillator. Given the risk of sudden death due to fatal ventricular arrhythmia, the woman required implantation of a defibrillator with pacemaker capability. Combined anesthesia-analgesia was used in order to minimize the risk of ventricular arrhythmia caused by increased serum concentrations of catecholamines. When cardioversion, defibrillation and anti-tachycardia functions had been deactivated, anesthesia was induced with propofol, fentanyl and rocuronium. Anesthesia was maintained with an infusion of propofol and remifentanil. We describe the pathophysiology and treatment of LQTS and discuss anesthetic management for repositioning a defibrillator in a patient with congenital LQTS.
