Objectives: This study aimed to determine how CIED-related complications affect all-cause and cardiovascular mortality over a long-term follow-up. Background: Although complications related to implantable electronic device (CIED) implantation are steadily increasing in Europe, little is known about the impact of complications other than device infection on mortality. Methods: The POINTED (Impact on Patient Outcome and health care utilization of cardiac ImplaNTable Electronic Device complications) registry was a prospective, multicenter, observational study designed to collect data on complications in patients undergoing de novo CIED implantation (NCT03612635). All consecutive patients were enrolled in 6 high-volume centers between January 2010 and December 2012 and followed up for at least 3 years. A complication was defined as any CIED-related adverse event requiring surgical revision after implantation. Results: During follow-up (median 56.9 months), we observed 283 complications in 263 of 2811 consecutive patients (71 ± 14 years of age, 66.7% men). Early complications (≤30 days) were associated with significantly lower cumulative survival from cardiovascular death in comparison with late complications and with freedom from complications. On multivariate analysis, early complication, pneumothorax, and pocket hematoma were significantly associated with a higher risk of all-cause death, while device infection remained the only complication significantly associated with a higher risk of cardiovascular death. Conclusions: All CIED-related complications are associated with an increased risk of cardiovascular mortality, and early complications are associated with an increased risk of all-cause mortality. These data underline the importance of specific measures aimed at reducing CIED complications and improving their management.
