The main purpose of this study is to assess the safety and efficacy of the prespecified protocol for determining the IVL balloon size based on intravascular imaging findings (IVUS or OCT). The IVL balloon size is decided according to the calcification pattern (i.e., circumferential or eccentric pattern). In cases of the circumferential pattern, IVL balloon size is defined as "larger distal reference lumen diameter (LDRLD) or LDRLD+0.25 mm". In cases of the eccentric pattern, "larger distal reference lumen diameter (LDRLD)-0.25 or 0.50 mm. When intravascular imaging after IVL shows >=2 cracks, drug-eluting stent implantation is recommended as the next step. If not, additional dilatation with a cutting balloon is recommended.
Safety,Efficacy
1) The success rate of making any calcium cracks (>=1) after IVL without any IVL-related complications (primary effectiveness endpoint)
2) 30-day outcomes (cardiac death, target vessel-related myocardial infarction, stent thrombosis, target vessel revascularization)(primary safety endpoint)
1) The success rate of making any calcium cracks (>=1) before stent implantation
2) Comparing the intravascular imaging findings before and after cutting balloon dilatation followed by IVL
3) Incidence rate of IVL-related complications (eg. major dissection and coronary perforation)
4) Factors associated with calcium fracture after IVL (comparison between IVUS and OCT)
5) Frequency of discordant results between OCT- and IVUS-based Ca scoring systems
6) The success rate of achieving the optimal stent expansion (SEI >=90%)
7) Factors associated with suboptimal stent expansion (SEI <90%)
8) The procedural success rate (residual stenosis <50% without any in-hospital events)
9) 1-year outcomes (cardiac death, target vessel-related myocardial infarction, stent thrombosis, target vessel revascularization)
