The study seeks to address the clinical question of how effectively a novel cutting balloon (Wolverine™) can modify calcified lesions for stent implantation in comparison with a non-compliant (NC) balloon, particularly when used alongside a bioabsorbable polymer-coated everolimus-eluting coronary stent (Synergy™). Most previous researches on cutting balloons focused on only severe calcifications and had limitations such as small sample sizes with retrospective designs, emphasizing on short-term imaging outcomes. This study differs by including mild to severe calcifications and evaluating long-term clinical outcomes, intraprocedural factors, and operator convenience. It aims to provide evidence that could potentially expand the indications for cutting balloon use and inform insurance coverage policies. The objective of the study is to test the safety and efficacy of the cutting balloon in preparing calcified coronary lesions for stent insertion compared to conventional methods.
