Inclusion criteria

Inclusion criteria: Consecutive chronic coronary syndrome patients who underwent PCI with RA for severe calcified lesions at our institution.

Exclusion criteria

Exclusion criteria: 1. patients with poor angiogram quality for calculating angiography-derived IMR. 2. restenosis lesion treated with a debulking device in the prior procedure. 3. first-generation drug eluting stent implantation. 4. coronary ostial lesion. 5. coronary artery graft lesion. 6. severe procedural complication such as persistent no flow, coronary perforation due to an RA burr, and requiring emergent surgical conversion. 7. hemodynamic instability at procedure. 8. patients who are deemed to ineligible for participation in this study by investigator.
