Abstract Calcified lesions still remain a technical challenge even in the treatment of infrainguinal artery disease. The aim of this retrospective, multicenter observational study was to investigate interventional outcomes of a high-speed rotational atherectomy device (Rotablator™) and to compare clinical outcomes in patients who underwent Rotablator and those who did not even after failed balloon angioplasty because of underlying calcified lesions. This study enrolled patients who underwent Rotablator (Rota group) and those who did not (Non-rota group) between January 2010 and 2014 December at 12 hospitals. A total of 67 limbs and 68 lesions in 65 patients were included (Rota group; 54 limbs and 55 lesions in 52 patients, Non-rota group; 13 limbs and 13 lesions in 13 patients). In the Rota group, a technical success rate was 94.5% with a complication rate of 1.8%, and all lesions underwent subsequent postdilatation following the adjunctive use of Rotablator, and approximately half of above-the-knee lesions underwent stent implantation. The Rota group had a significantly lower clinically driven reintervention rate at 12 months than the Non-rota group (26.5% vs. 58.3%, respectively, p = 0.046). In addition, Rota group showed a trend toward a higher amputation-free survival compared to the Non-rota group at 1 month (Rota; 98.0% vs. Non-rota; 84.6%, respectively, p = 0.10). Rotablator was used as an adjunctive device with a high technical success and a low complication rates, and Patients who underwent Rotablator yielded a significantly lower clinically driven reintervention rate at 12 months compared to those who did not even after failed balloon angioplasty.
