Introduction: The treatment of calcified femoropopliteal lesions is complex. Plaque debulking devices may improve results in such cases. Results have been reported, but information on real world scenarios is scarce.

Objective: To determine if Directional Atherectomy with Antirestenotic Therapy (DAART) is effective on the management of Chronic Limb-Threatening Ischemia (CLTI) on real world Latin-American patients.

Secondary objective: To evaluate quality of life.

Design: Observational, retrospective non-randomized study.

Methodology: Retrospective analysis of a single center, single arm case series. Primary outcomes overall survival and amputation-free survival. Secondary outcome, Quality of Life (QoL) measured using the EQ-5D-5L questionnaire.

Results: thirty-one patients were treated with DAART in a 6 year period with a 93.5% rate of technical success, overall survival and amputation-free survival were 87% and 88% with a mean follow-up of 57 months. Most of them reported good QoL.

Conclusion: DAART is useful on the treatment of Latin-American patients with advanced CLTI.
