case_images: CAG demonstrated residual severely calcified stenosis in the proximal RCA with patent antegrade coronary flow (Figure 1).

case_images: Finally, we switched back to rotational atherectomy and were subsequently able to pass the burr beyond the angulated calcified lesion without complications (Figure 2) and confirmed a crack using IVUS.
case_images: Successful stent deployment within the lesion.

case_images: Following effective dilation with a 3.0 mm high-pressure balloon (CELUSUS 3.0 x 8 mm, NIPRO, Osaka, Japan), we deployed a bioresorbable polymer everolimus-eluting stent (Synergy 2.5 x 24 mm, Boston Scientific) (Figure 3).
case_images: Final angiographic results after stent implantation and after dilatation.
