BACKGROUND: A complex transvenous lead extraction (TLE) procedure could be associated with lower success and higher complication rates in inexperienced hands. In this study, we aim to assess the factors that determine procedural difficulty in TLE.
METHODS: We retrospectively studied 200 consecutive patients undergoing TLE in a single referral centre from June 2020 to December 2021. Lead extraction difficulty was assessed by the success of simple manual traction with or without a locking stylet, the need for advanced extraction tools and the number of tools required to extract the lead. Logistic and linear regression analyses were used to determine the factors independently affecting these 3 parameters.
RESULTS: 363 leads were extracted from 200 patients (79% males, mean age 66.85 years). The indication for TLE was device-related infection in 51.5%. Multivariate analysis revealed the lead indwelling time to be the only factor affecting the 3 parameters of difficulty. Passive fixation leads and dual coil leads increased procedural difficulty by affecting 2 parameters each. Factors that affected one parameter included infected leads, coronary sinus leads, older age of the patient and a history of valvular heart disease, all associated with a simpler procedure. Right ventricular leads were associated with a more complex one.
CONCLUSION: The most important factor that increased TLE procedural difficulty was a longer lead indwelling time, followed by passive fixation and dual-coil leads. Other contributing factors were the presence of infection, coronary sinus leads, older patients, a history of valvular heart disease and right ventricular leads.
