1: Sion blue was inserted for open lumen.2: IVUS examination was performed. 3: Miracle12 with DLC was penetrated inside calcified nodule with IVUS guidance.4: Guidewire was exchanged to rota floppy.5: Debunking by rotablator (2.15mm/180000bpm) was performed with temporary pacing back-up.6: POBA was performed by 4.25mm high pressure balloon .7: Final angiography was assessed.8: CAG follow-up was assessed 1-year later, which showed no significant stenosis by both physiological assessment and IVUS findings.
- Case Summary:
Calcified nodule sometimes led malignant restenosis after DES implantation. However, ARCADIA technique could be useful strategy for such kind of tough calcified nodule which was considered as difficult to be treated by conventional approach.
