Cutting balloon to optimize predilation for stent implantation: The COPS randomized trial.

Objectives: The objective of this study is to investigate the use of cutting balloon (CB) inflated at high pressure compared with noncompliant balloon (NCB) for the treatment of calcified coronary lesions.

Background: No data are available regarding the safety and efficacy of CB inflated at high pressure in coronary artery calcifications.

Methods: Patients with calcified lesions (more than 100° of calcium demonstrated at baseline intravascular ultrasound) were randomized.
