Multicenter Study Clinical TrialMulticenter experience with transvenous lead extraction of active fixation coronary sinus leads.
Active fixation coronary sinus (CS) leads limit dislodgement and represent an attractive option to the implanter. Although extraction of passive fixation CS leads is a common and frequently uncomplicated procedure, data regarding extraction of chronically implanted active fixation CS leads are limited. ⋯ Although TLE of active fixation CS leads can be a safe procedure in select patients and experienced hands, powered sheaths and aggressive techniques are frequently required for successful removal despite relatively short implant durations. This raises significant concern regarding future TLE of active fixation CS leads with longer implant durations.

Case ReportsInduction of ventricular tachycardia by alternate current due to an insufficiently grounded electrical system.
Detection of electromagnetic interference followed by inappropriate therapy by implantable cardioverter-defibrillators (ICDs) has been well documented in several case reports as well as in follow-up studies. This is a report of a case where electromagnetic interference induced ventricular tachycardia, with appropriate detection and treatment by the patient's ICD.
