Mechanical power sheath mediated recanalization and lead implantation in patients with venous occlusion: Technique and results

Introduction Chronic venous occlusion hampers lead revisions and upgrades in patients with a cardiac implantable electronic devices (CIEDs). This can make cardiothoracic surgery, venoplasty or contra-lateral implantation of leads with tunneling necessary. A technique using venous recanalization may be a preferred alternative. We assessed the efficacy and safety of this new technique. Methods and results From 2009–2016 all consecutive patients planned for lead revision or upgrade with known chronic venous occlusion were studied. All patients underwent extraction of an existing malfunctional or functional CIED lead with the Cook Evolution mechanical power sheath. By using the lumen of the sheath, endovascular access to the heart was obtained for new leads. 42 patients (107 leads, 2.6±1.1) were included. The indication for this procedure was replacement of malfunctional leads (n = 35,83%) or device upgrade (n = 7,17%). In total 77 leads were extracted (30 leads stayed in situ) with a mean age at time of extraction of 8.4 years. Because of damage to bystander leads during extraction 2 additional leads (one RA lead, one LV lead) were extracted. Clinical success was achieved in 41 patients (97%) and complete success in 39 patients (93%). There were 2 minor complications (2 pocket hematomas, managed conservatively) and 1 major complication (tamponade, needing thoracotomy). Mean procedure time was 3.0 hours (median 2.0, range 1:28-5:35 hours) with a mean fluoroscopy time of 14.9±12.5 min. Conclusions The technique of Evolution mediated recanalization in case of lead revisions or upgrades is feasible with an acceptable safety profile and high efficacy.
