Incidence, Patterns, and Outcomes following Transvenous Cardiac Device Lead Macrodislodgement: Insights from a Population-Based Study

Lead dislodgement is a relatively infrequent complication after implantation of transvenous cardiac implantable electronic devices (CIED). The incidence of lead dislodgement is estimated at 1%-8% 1, 2. Lead macro dislodgement (LMD) refers to leads that are grossly dislodged as seen on chest radiography or other cross-sectional imaging studies. Previous studies categorized the various types and mechanisms of LMD using the terms “twiddler,” “reel,” “reverse reel” and “ratchet syndrome” 3-6. Patient characteristics such as female sex, obesity and the presence of multiple transvenous leads have been associated with LMD 5, 7.
