Is this trial a fit for you?
✓Likely a good fit
Ideal candidates for this registry are patients in Japan who are undergoing transvenous lead extraction.
✕Probably not a fit
Patients who receive open-chest surgical extraction alone or those who refuse to consent will not benefit from this registry.

What this trial studies
The Japanese Lead Extraction (J-LEX) Registry is an observational nationwide registry that collects data on patients undergoing transvenous lead extraction in Japan. Conducted by the Japanese Heart Rhythm Society in collaboration with the National Cerebral and Cardiovascular Center, this registry aims to gather information on the success rates, complications, and patient outcomes associated with lead extraction procedures. Data will be collected prospectively using a Research Electronic Data Capture (REDCap) system, focusing on patient backgrounds, lead characteristics, and procedural details. The findings will help identify predictive factors for outcomes and improve clinical practices in lead extraction.
Why it matters
Potential benefit: If successful, this registry could enhance the understanding of lead extraction outcomes and complications, leading to improved patient care and safety.
How similar studies have gone: Other observational registries have shown success in improving clinical outcomes and understanding procedural risks, making this approach both relevant and valuable.
