Wadhwani L, Occhipinti K, Selim A, et al. - In cardiovascular implantable electronic device (CIED) implanted patients, most acute complications were diagnosed either within the first 6 hours or more than 24 hours post-implantation. Discharge following 6 hours of proper monitoring can be considered, with rare exception.

• This retrospective cohort study included adults 18 years or older who had CIED implantation (n = 2421).

• Pericardial effusion or cardiac tamponade, pneumothorax or hemothorax, lead dislodgment, and hematomas necessitating surgical intervention were diagnosed in 13 (0.53%), 19 (0.78%), 11 (0.45%), and in 5 patients (0.2%), respectively.

• Total 48 acute complications occurred; 43 (90%) either within 6 hours or more than 24 hours post-procedure.

• During the index hospitalization, intervention was needed for only 3 acute complications identified between 6 and 24 hours (0.12% of all cases).
