ICD lead abandonment is without risk? A case of “lead on lead crime”

ICD lead abandonment is without risk? A case of “lead on lead crime”

Introduction Lead failure rates of implantable cardioverter-defibrillators (ICDs) vary depending on design and composition, and can be as high as 40% a few years post implant. The Sprint Fidelis lead (Medtronic, Minneapolis, MN) was recalled in 2007 because it is prone to fracture, particularly to its pacesense conductor, which predisposes patients to inappropriate shocks; its yearly failure ra...

A case of Durata ICD lead coil externalization: Inside-out lead abrasion?

The St Jude Medical Durata lead was produced in response to the recalled Riata and Riata ST leads in November 2011 after concerns of lead durability and inside-out abrasion. In order to protect against this susceptibility, the Riata ST Optim and Durata leads were coated with an abrasionresistant layer of silicone–polyurethane copolymer (Optim) tubing. We report a case of Durata lead extraction ...

The Lead Extractor's Toolbox: A Review Of Current Endovascular Pacemaker And ICD Lead Extraction Techniques

Introduction Recently introduced pacemaker leads float freely within the veins and myocardium. Later on, fibrous encapsulation of the lead develops 1. These adhesions not only occur at the lead tip but are commonly found anywhere along the whole length of the lead at sites where the lead is in contact with the vein or the myocardium 1-4. These adhesions hamper lead removal as tight scar tissue ...

Subcutaneous ICD lead position affects defibrillation threshold

Introduction Subcutaneous implantable cardioverter-defibrillators (S-ICD) provide an alternative to traditional transvenous implantable cardioverter-defibrillators (TV-ICD) and avoid complications associated with intravascular access and leads. They are highly effective in detecting and treating ventricular arrhythmias, with comparable inappropriate shock rates. Use of S-ICD is anticipated to i...
