While the superior access is standard, complex cases may benefit from the Tandem approach, combining femoral and superior access to improve efficacy and safety.

Clinical procedural success was 97.3%, and complete lead removal 93%. Use of Medtronic leads was the sole independent predictor of complete lead removal. Major complications occurred in 3.4% of cases, with no procedural mortality.
