Prospective long-term evaluation of Optim-insulated (Riata ST Optim and Durata) implantable cardioverter-defibrillator leads

Over a mean follow-up of 3.2 years, Optim-insulated leads have low rates of all-cause mechanical failure and no observed externalized conductors. Independent analyses of these registries are designed to provide reliable long-term follow-up information and are ongoing.
