In order to identify potential risk factors for acute lead dislodgement, we conducted dynamic finite element simulations of pacemaker lead dislodgement in marginal LV vein. We considered factors such as mismatch in lead and vein diameters, velocity of myocardial motion, branch angle between the insertion vein and the coronary sinus, degree of slack, and depth of insertion. The results show that large lead-to-vein diameter mismatch, rapid myocardial motion, and superficial insertion are potential risk factors for lead dislodgement. In addition, the degree of slack presents either a positive or negative effect on dislodgement risk depending on the branch angle. The prevention of acute lead dislodgment can be enforced by inducing as much static friction force as possible at the lead-vein interface, while reducing the external force. If the latter exceeds the former, dislodgement will occur. The present findings underscore the major risk factors for lead dislodgment, which may improve implantation criterion and future lead design.<\/jats:p>","DOI":"10.1115\/1.4003323","type":"journal-article","created":{"date-parts":[[2010,12,23]],"date-time":"2010-12-23T23:02:52Z","timestamp":1293145372000},"update-policy":"https:\/\/doi.org\/10.1115\/crossmarkpolicy-asme","source":"Crossref","is-referenced-by-count":4,"title":["Simulation of LV Pacemaker Lead in Marginal Vein: Potential Risk Factors for Acute Dislodgement"],"prefix":"10.1115","volume":"133","author":[{"given":"Xuefeng","family":"Zhao","sequence":"first","affiliation":[{"name":"Department of Biomedical Engineering, Indiana University Purdue University Indianapolis, Indianapolis, IN 46202"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mike","family":"Burger","sequence":"additional","affiliation":[{"name":"Livermore Software Technology Corporation, Livermore, CA 94550"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yi","family":"Liu","sequence":"additional","affiliation":[{"name":"Department of Biomedical Engineering, Indiana University Purdue University Indianapolis, Indianapolis, IN 46202"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mithilesh K.","family":"Das","sequence":"additional","affiliation":[{"name":"Krannert Institute of Cardiology, Roudebush VA Medical Center, Indiana University School of Medicine, Indianapolis, IN 46202"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"William","family":"Combs","sequence":"additional","affiliation":[{"name":"Department of Biomedical Engineering, Indiana University Purdue University Indianapolis, Indianapolis, IN 46202"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jonathan F.","family":"Wenk","sequence":"additional","affiliation":[{"name":"Department of Surgery and San Francisco VA Medical Center, University of California at San Francisco, San Francisco, CA 94121"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Julius M.","family":"Guccione","sequence":"additional","affiliation":[{"name":"Department of Surgery and San Francisco VA Medical Center, University of California at San Francisco, San Francisco, CA 94121"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ghassan S.","family":"Kassab","sequence":"additional","affiliation":[{"name":"Department of Surgery, and Department of Cellular and Integrative Physiology, Department of Biomedical Engineering, Indiana University Purdue University Indianapolis, Indianapolis, IN 46202"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"33","published-online":{"date-parts":[[2011,2,7]]},"reference":[{"issue":"11","key":"2019100323232360100_c1","doi-asserted-by":"publisher","first-page":"1466","DOI":"10.1111\/j.1540-8159.2009.02514.x","article-title":"Achieving Permanent Left Ventricular Pacing-Options and Choice","volume":"32","author":"Lau","journal-title":"Pacing Clin.
