We conducted a prospective observational study to evaluate the indications, technique, in‐hospital and 9‐month results of consecutive patients treated with rotational atherectomy (RA) in 12 centers during 1 year, as well as their relationship with volume of RA activity. The study included 345 lesions in 289 patients treated (4.4% ± 2.6% of procedures at the participating centers). The lesions were mostly calcified (63%) and type B2 or C (74%). Procedural success was obtained in 94% of patients, with a major adverse cardiac event (MACE) rate of 4.5%. At 9 months, MACE occurred in 17.3%. Multivariate analysis identified multivessel disease and slow flow as negative predictors of procedural success, whereas balloon pressure ≤ 6 atm and hypercholesterolemia were associated with decreased MACE at 9 months. Center RA volume was not associated with in‐hospital or 9‐month outcome. We conclude that RA, even when used sporadically in selected complex lesions, can provide good immediate and mid‐term results.
