Abstract only Background: Atherectomy devices are used during below-the-knee (BTK) artery interventions to tackle the calcium burden in peripheral arteries. Methods: We examined 1542 patients from the XLPAD Registry (NCT01904851) from 2006-2021 who underwent BTK endovascular intervention, stratified by use of atherectomy device or not. The primary outcome was the incidence of major adverse limb events (MALE), a composite of all-cause death, clinically driven revascularization, amputation, non-fatal myocardial infarction (MI), and stroke. Results: 710 (46%) patients were treated with an atherectomy device and 832 were not. Mean age 68 years, predominantly male (72%) and Caucasian (58%). Cardiovascular risk factors were equally distributed among both groups, except hyperlipidemia was more prevalent in the atherectomy group (83% vs. 78%, p=0.01). Both groups had similar Ankle-Brachial Indexes. Atherectomy group had more multivessel interventions (2.5 vs 1.9 lesions per case, p
