Some severely calcified lesions remain untreatable with conventional balloons or even atherectomy devices. Intravascular lithotripsy is a new option for treating severe calcification.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Case summary<\/jats:title>\n                  <jats:p>Herein, we describe a case of ischaemic cardiomyopathy with a thick, circumferential calcified lesion in the proximal and mid-segments of the left anterior descending coronary artery. In the first session, high-pressure balloons, cutting balloons, and rotational atherectomy failed to disrupt the calcification. In the staged additional treatment that was subsequently planned, eight cycles of intravascular lithotripsy created multiple fractures in the deep calcification, resulting in successful stent deployment. The effect of intravascular lithotripsy was observed mainly in calcified areas with lipid components detected using near-infrared spectroscopy-intravascular ultrasound.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Discussion<\/jats:title>\n                  <jats:p>Our report suggests the efficacy of employing a combined strategy of rotational atherectomy with small burrs and intravascular lithotripsy in the treatment of severe calcification with a minimal risk of complications. Our study introduces a novel aspect by utilizing near-infrared spectroscopy-intravascular ultrasound to evaluate calcified lesions before performing intravascular lithotripsy. To our knowledge, there have been no similar reports to date. The effect of intravascular lithotripsy on calcified lesions may be related to the distribution of lipid components and\/or heterogeneity within the calcification.<\/jats:p>\n               <\/jats:sec>","DOI":"10.1093\/ehjcr\/ytae504","type":"journal-article","created":{"date-parts":[[2024,9,19]],"date-time":"2024-09-19T18:16:18Z","timestamp":1726769778000},"source":"Crossref","is-referenced-by-count":2,"title":["Staged strategy of combined rotational atherectomy and intravascular lithotripsy for severely calcified lesions: an evaluation using multimodality intracoronary imaging\u2014a case report"],"prefix":"10.1093","volume":"8","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5719-2213","authenticated-orcid":false,"given":"Yusuke","family":"Miura","sequence":"first","affiliation":[{"name":"Department of Cardiovascular Medicine, Kyorin University Hospital , 6-20-2 Shinkawa, Mitaka, Tokyo 181-0004 ,","place":["Japan"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9903-5945","authenticated-orcid":false,"given":"Kohei","family":"Koyama","sequence":"additional","affiliation":[{"name":"Department of Cardiovascular Medicine, Kyorin University Hospital , 6-20-2 Shinkawa, Mitaka, Tokyo 181-0004 ,","place":["Japan"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Keiichi","family":"Izumi","sequence":"additional","affiliation":[{"name":"Department of Cardiovascular Medicine, Kyorin University Hospital , 6-20-2 Shinkawa, Mitaka, Tokyo 181-0004 ,","place":["Japan"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hiroyuki","family":"Yamazaki","sequence":"additional","affiliation":[{"name":"Department of Cardiovascular Medicine, Kyorin University Hospital , 6-20-2 Shinkawa, Mitaka, Tokyo 181-0004 ,","place":["Japan"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kyoko","family":"Soejima","sequence":"additional","affiliation":[{"name":"Department of Cardiovascular Medicine, Kyorin University Hospital , 6-20-2 Shinkawa, Mitaka, Tokyo 181-0004 ,","place":["Japan"]}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"286","published-online":{"date-parts":[[2024,9,19]]},"reference":[{"key":"2024103011433928000_ytae504-B1","first-page":"1845","article-title":"Ischemic outcomes after coronary intervention of calcified vessels in acute coronary syndromes.
