Probability of TLE complexity using LECOM score

Predictors of the risk of difficulties during TLE procedure Value
1. Patient age during TLE (Years)
2. Patient age at first CIED implantation (Years)
3. Age of oldest lead to be removed (Years)
4. Age of oldest lead to be removed / patient age during TLE (Years)
5. Number of leads to be extracted
6. Number of abandoned leads to be extracted
7. Number of previous CIED-related procedures (including implantation)
8. Passive fixation leads to be extracted (except LV leads)
