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.
Successful stent deployment within the lesion.

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).

A final coronary angiogram showed adequate and favorable dilatation of the culprit lesion (Figure 4).
