BACKGROUND: Coronary calcification negatively affects the safety and effectiveness of percutaneous coronary intervention. There is a lack of randomized comparisons among different plaque modification techniques. OBJECTIVES: The aim of this study was to compare rotational atherectomy (RA), excimer laser coronary angioplasty (ELCA), and intravascular lithotripsy (IVL) for the treatment of patients with calcified coronary stenosis. METHODS: Patients with moderate to severe calcified coronary lesions were randomly assigned to percutaneous coronary intervention with RA, IVL, or ELCA. The primary endpoint was the percentage of stent expansion by optical coherence tomography. An intention-to-treat, noninferiority analysis was conducted. RESULTS: ) were similar among the 3 arms. IVL proved to be noninferior to RA, with no differences in stent expansion (RA, 86.4% ± 14.1%; IVL, 85.6% ± 13.3%; P = 0.77). ELCA did not reach noninferiority in the intention-to-treat analysis. The rate of complications was low, with no significant differences in the 3 arms but numerically lower with IVL. CONCLUSIONS: In the first randomized trial comparing RA, IVL, and ELCA for the treatment of patients with calcified coronary lesions, IVL was noninferior to RA in terms of stent expansion. ELCA did not reach this noninferiority margin compared with RA. No significant differences were observed among the 3 arms regarding minimum stent area, procedural success rate, and complications, which were numerically l...
