“…In addition, isodiametric and active fixation leads are likely to be more easily removed than non-isodiametric and passive fixation leads. Lastly, expanded polytetrafluoroethylenecovered ICD leads may reduce tissue ingrowth allowing for easier extraction [30]. As CIED extraction becomes more common, extraction-conscious implantation will undoubtedly continue to be of great importance in reducing the risk of subsequent extraction procedures.…”

With the increasing numbers of cardiac implantable devices in use, lead extraction has become a critical procedure in remedying device-related infections and complications. Lead extraction technology has grown considerably over the past two decades from simple traction maneuvers to the use of powered, telescoping sheaths equipped with laser technology. Data from single center experiences and randomized control trials have continued to demonstrate the safety and efficacy of the most current lead extraction technology. Still, major complications occur in less than 1% of patients. Patient preparation and in-place laboratory protocols are important for the prevention of complications and the rapid diagnosis and treatment of life-threatening complications should they arise.

“…These leads have been shown to become tightly encapsulated by fibrosis and can be very difficult to remove, in animal experiments as well as in humans [25,26]. Gross and histological cardiac anatomic findings in 7 patients with chronically indwelling coronary sinus ICD leads have been studied at autopsy or cardiac transplantation.…”

“…Significant obstruction following transvenous pacemaker implantation is common, being reported in 14 to 37% of cases (Haghjoo et al 2007;Korkeila et al 2007;Oginosawa et al 2002;Sticherling et al 2001). These obstructions may lead to superior vena cava syndrome (Goudevenos et al 1989;Mazzetti et al 1993) or, with a 0.4-0.8% chance of fatal or near fatal complications, make pacemaker lead replacement or removal difficult and dangerous (Byrd et al 2002;Smith et al 1994;Wilkoff et al 2005Wilkoff et al , 1999. These issues are especially concerning for children, due to their smaller vessels and the need for life-long pacing.…”

New Insights into Pacemaker Lead-Induced Venous Occlusion: Simulation-Based Investigation of Alterations in Venous Biomechanics

et al. 2010

Venous obstruction is a major complication of transvenous pacemaker placement. Despite the increasing use of pacemakers and implantable cardiac defibrillators, a lack of understanding remains with regard to risk factors for the development of device-associated venous obstruction. We hypothesize that computational fluid dynamics simulations can reveal prothrombogenic locations and define thrombosis risk based on patient-specific anatomies. Using anatomic data derived from computed tomography, computer models of the superior vena cava, subclavian, innominate, and internal jugular veins were constructed for three adult patients with transvenous pacemakers. These models were used to perform patient-specific simulations examining blood flow velocity, wall shear stress, and blood pressure, both with and without the presence of the pacing leads. To better quantify stasis, mean exposure time fields were computed from the venous blood flow data. In comparing simulations with leads to those without, evident increases in stasis at locations between the leads and along the surface of the vessels closest to the leads were found. These locations correspond to regions at known risk for thrombosis. This work presents a novel application of computational methods to study blood flow changes induced by pacemaker leads and possible complications such as venous occlusion and thrombosis. This methodology may add to our understanding of the development of lead-induced thrombosis and occlusion in the clinical arena, and enable the development of new strategies to avoid such complications.

Improved Extraction of ePTFE and Medical Adhesive Modified Defibrillation Leads from the Coronary Sinus and Great Cardiac Vein

Abstract: Tissue ingrowth is a major impediment to the removal of defibrillation leads implanted in the CS and GCV of sheep. Reduction of tissue ingrowth by coating the shocking coils with ePTFE or by backfilling with MA facilitates transvenous lead removal with reduced tissue trauma.
