| アブストラクト | BACKGROUND: The increasing use of cardiovascular implantable electronic devices (CIEDs) has heightened the need for transvenous lead extraction (TLE). Although Japan has a certification system for TLE-capable hospitals, nationwide trends and regional disparities remain unclear. METHODS: We retrospectively analyzed the Japanese Registry of All Cardiac and Vascular Diseases Diagnosis Procedure Combination/Per Diem Payment System, including patients undergoing TLE or other CIED-related procedures between April 2015 and March 2022. RESULTS: Among 3573 TLE cases from 108 hospitals, procedure volumes steadily increased. The median patient age increased from 74 to 77 years, and comorbidity burden also rose over time. During this period, the proportion of non-infectious indications rose from 17.0% in 2015 to 38.9% in 2021. Cardiac tamponade was the most frequent complication, and advanced age and renal disease independently predicted complications or in-hospital death. Marked regional disparities were observed in CIED implantation patterns, TLE volume, and indications across Japan. CONCLUSIONS: Non-infectious TLEs have increased safely in Japan, contributing to an overall growth in TLE procedures. However, substantial regional disparities persist in both procedural volume and indications. Standardized care strategies addressing these disparities are warranted to optimize TLE practice nationwide. |
