This is a registry study—meaning researchers collect and study real-world medical information—that follows patients who have implanted heart devices (like pacemakers or ICDs) and need surgery or catheter procedures for other reasons. The goal is to understand what happens during and after these procedures and find the safest ways to manage patients' heart devices during surgery.
More and more people have implanted heart devices, and many of them need surgery for unrelated reasons. However, most of the current guidelines for how to manage these devices during surgery come from old case reports and small studies. This trial exists to gather modern, real-world data so doctors can develop better recommendations to prevent device-related problems during surgery.

You do not need to do anything special—this is a data collection study. Researchers will review your existing medical records and the information from your heart device checks (interrogations) before and after your surgery or procedure. Your data will be collected at two heart centers in Germany and added to a registry to help improve care for future patients with similar devices.
