Background Extraction of the implantable cardioverter-defibrillator (ICD) leads could be a difficult procedure due to fibrous tissue around the lead and anatomical variations. In this report, we present our experience in the radiographic predictors of failure of simple manual traction (SMT) in patients with dual-coil ICD requiring lead extraction (LE). Methods Between January 2017 and February 2021, 103 leads were removed in 65 consecutive patients; 65 (63.1%) were dual-coil ICD leads, 22 (21.4%) were atrial, and 16 (15.5%) were coronary sinus leads. Patient-based and procedural data were collected and analyzed retrospectively. Clinical and procedural characteristics were compared and radiographic predictors of failure of SMT of ICD leads were assessed. Projected anteroposterior (AP) lead tortuosity was measured and lead slack score was estimated on chest X-ray (CXR). Results Simple manual traction failed in 27 (42%) of the ICD leads. Ottawa slack score (odds ratio [OR] 2.368, 95% CI [1.261-4.447]; P = 0.007), AP lead tortuosity > 1.10 (OR 7.477, 95% CI [1.718-35.542]; P = 0.007), and number of previous interventions (OR 6.016, 95% CI [1.184-30.557]; P < 0.030) were found to be independently related to the failure of SMT. Receiver-operator characteristic curve analysis yielded an AP lead tortuosity cutoff value of > 1.10 for predicting the failure of SMT. The area under the curve was 0.744; the 95% confidence interval (CI) was 0.617 to 0.871 (P = 0.001), with a sensitivity of 63% and a specificity of 73%. Conclusion Simple manual traction success in our study varied based on radiographic lead-related parameters. Before planning the procedure, increased AP lead tortuosity in vasculature and higher lead slack score can be easily determined on CXR and may be associated with more fibrous adherences, the complexity of the LE, and failure of SMT.
