Predictors of Early Cardiac Implantable Electronic Device Lead Dislodgement in the Elderly

Introduction: One of the most frequent cardiac implantable electronic device (CIED) implantation complications is lead dislodgement, especially in the older adult population. Little evidence is available about the influence of frailty on the risk of lead dislodgment after CIED implantation procedures; thus, the evaluation of frailty could be relevant for the course and safety of the implantation procedure, especially among the elderly with cardiovascular diseases. This study aimed to assess the risks and predictors of early lead dislodgement in the elderly population. Methods: Between 2008 and 2021, 14,293 patients underwent implantations. In 400 elderly patients, lead dislodgement was confirmed, and frailty was retrospectively calculated. Results: The most frequent dislodgement according to the lead position was that of the atrial lead (133; 33.3%). In the logistic regression, frailty (OR: 1.8196, 95% CI:1.4991–2.2086; p < 0.0001) and age (OR: 1.0315, 95% CI:1.0005–1.0634; p < 0.0461) were independent predictors of early dislodgement. In the female group, frailty (OR: 2.1185, 95% CI: 1.5530–2.8899; p < 0.0001) was an independent predictor of early dislodgement. Similarly, in the male group, frailty (OR: 1.6321, 95% CI:1.2725–2.0934; p < 0.0001) was an independent predictor of early dislodgement. Conclusion: Lead dislodgement often occurs in the elderly. Frailty in both men and women is a predictive factor of early lead dislodgment. Evaluating frailty may be an essential element of proper selection, especially in the elderly undergoing CIED procedures, and, consequently, it could help prevent further complications.
