Intracoronary imaging-guided rotational atherectomy combined with intravascular lithotripsy in the treatment of severe coronary artery calcification-A case report.

ABSTRACT:

Background

Severe coronary artery calcification increases the difficulty of percutaneous coronary intervention procedures and impairs stent expansion. Herein, we report a case of a patient who was successfully treated with rotational atherectomy using a stepped burr strategy combined with intravascular lithotripsy for plaque modification under intracoronary imaging.

Case summary

A 65 year-old woman presented to our hospital with recurrent chest pain evolving for 1 year. Coronary angiography showed approximately 80% stenosis of the proximal mid-left anterior descending artery. Intravascular ultrasound (IVUS) and optical coherence tomography (OCT) revealed a 360° annular calcification. The calcification was rotablated with 1.5 and 1.75 burrs, and the lesion was undilatable wit
