The purpose of this registry is to evaluate the impact on patient outcome and on healthcare utilization of cardiac implantation electronic device complications during a long-term follow-up.

Multicentric, observational, prospective registry enrolling consecutive patients underwent pacemaker or defibrillator implantation, aimed to evaluate the impact of cardiac implantable device complications requiring surgical revision on healthcare utilization (number and length of hospitalizations), and on patient outcome (all-cause mortality and cardiac mortality), during a long-term follow-up.

Inclusion Criteria:

• patients underwent cardiac implantable electronic device implantation according to current guidelines during the enrollment period.

Exclusion Criteria:

• patients already carriers of a cardiac implantable electronic device underwent replacement or upgrading of device.

Patients with indication to receive a cardiac implantable electronic device (pacemaker or defibrillator).
