Incidence, patterns, and outcomes after transvenous cardiac device lead macrodislodgment: Insights from a population-based study

Lead dislodgment is a relatively infrequent complication after implantation of transvenous cardiac implantable electronic devices (CIEDs). The incidence of lead dislodgment is estimated at 1% –8%.1,2 Lead macrodislodgment (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 Patien t characteristics such as female sex, obesity, and presence of multiple transvenous leads have been associated with LMD.
