The Japanese Lead Extraction Registry collects real-world information from patients undergoing procedures to safely remove old wires (leads) from implanted heart devices. By gathering data from many hospitals across Japan, researchers hope to understand how often complications occur, which patients do well, and what factors predict good outcomes from these procedures.
As more patients receive implanted heart devices, some eventually need their old leads removed due to infection, malfunction, or other reasons. Doctors need better information about how often and why complications happen during these removal procedures, and which patients are at higher risk—so this registry is gathering that real-world evidence.

If you enroll, your doctors will collect information about your medical history, your heart device and its leads, details of your removal procedure, and how you recover over the next 30 days. All your information will be anonymized (de-identified) before it's sent to the research team. You will not receive any experimental medication or procedure—only standard care, with your data being recorded and studied.
