Intravascular Lithotripsy Treatment With In-Stent Underexpansion Followed by Angiography, Optical Coherence Tomography, and Coronary Angioscopy

Year: 2025

Type: article

Abstract: BACKGROUND: There are no reports in which in-stent restenosis (ISR) lesion treated by intravascular lithotripsy (IVL) is followed by coronary angioscopy examination in addition to coronary angiography and optical coherence tomography. CASE SUMMARY: A 53-year-old man with stable angina underwent drug-eluting stent implantation in the left anterior descending artery lesion with severe calcification 4 years before and an underexpansion remained. Despite high-pressure balloon dilatations with multiple sessions, adequate lumen area could not be obtained. However, we performed revascularization with IVL and excellent stent expansion was achieved. Seven months later, follow-up coronary angiography with optical coherence tomography and coronary angioscopy revealed sustained acute lumen gain with no evidence of stent recoil or ISR. DISCUSSION: ISR lesion was successfully treated with IVL and assessed by multimodality imaging. TAKE-HOME MESSAGE: This case highlights the potential efficacy of IVL for underexpanded ISR lesions with severe calcification.
