Although excimer laser coronary atherectomy (ELCA) with contrast medium was shown to be effective to improve stent underexpansion in undilatable lesions, precise mechanism of this technique was not well understood. We report a case of ISR with stent underoptimal implantation within a circumferential\u2010calcified atherosclerotic plaque beneath the stent strut that could not be dilated by repeated high\u2010pressure balloon inflations. After rotational atherectomy, the mechanism of the underexpanded lesion could be obtained by optical frequency domain imaging (OFDI). High\u2010pressure balloon could not dilate the underexpanded stent. Since ELCA with saline flush only gave intimal erosions and minor dissections, additional high\u2010pressure balloon was also ineffective. Finally, ELCA with contrast medium could disrupt the calcific lesion beneath the underexpanded stent. The angiographic and OFDI findings confirmed the full stent expansion could be accomplished by further balloon dilatation with an ordinary pressure. ELCA with contrast medium is feasible to improve stent underexpansion by disrupting the calcified plaque behind the stent strut. \u00a9 2015 Wiley Periodicals, Inc.<\/jats:p>","DOI":"10.1002\/ccd.25915","type":"journal-article","created":{"date-parts":[[2015,3,7]],"date-time":"2015-03-07T16:34:16Z","timestamp":1425746056000},"page":"946-949","source":"Crossref","is-referenced-by-count":24,"title":["The effectiveness of excimer laser coronary atherectomy with contrast medium for underexpanded stent: The findings of optical frequency domain imaging"],"prefix":"10.1002","volume":"86","author":[{"given":"Takashi","family":"Ashikaga","sequence":"first","affiliation":[{"name":"Department of Cardiovascular Medicine Tokyo Medical and Dental University  Tokyo Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shunji","family":"Yoshikawa","sequence":"additional","affiliation":[{"name":"Department of Cardiovascular Medicine Tokyo Medical and Dental University  Tokyo Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mitsuaki","family":"Isobe","sequence":"additional","affiliation":[{"name":"Department of Cardiovascular Medicine Tokyo Medical and Dental University  Tokyo Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2015,3,30]]},"reference":[{"key":"e_1_2_4_2_1","doi-asserted-by":"publisher","DOI":"10.1136\/hrt.2004.056648"},{"key":"e_1_2_4_3_1","first-page":"697","article-title":"Cutting balloon angioplasty for underexpanded stent deployed through struts of previously implanted stent","volume":"14","author":"Balan O","year":"2002","journal-title":"J Invasive Cardiol"},{"key":"e_1_2_4_4_1","doi-asserted-by":"publisher","DOI":"10.1159\/000177125"},{"key":"e_1_2_4_5_1","doi-asserted-by":"publisher","DOI":"10.1002\/ccd.21490"},{"key":"e_1_2_4_6_1","first-page":"E161","article-title":"A novel approach for under\u2010expanded stent: Excimer laser in contrast medium","volume":"24","author":"Egred M","year":"2012","journal-title":"J Invasive Cardiol"},{"key":"e_1_2_4_7_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.carrev.2013.10.005"},{"key":"e_1_2_4_8_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijcard.2011.03.021"},{"key":"e_1_2_4_9_1","unstructured":"DeckelbaumLI NatarajanMK BittlJA RohlfsK ScottJ ChisholmR BowmanKA StraussBH.Effect of intracoronary saline infusion on dissection during excimer laser coronary angioplasty: A randomized trial.J Am Coll Cardiol1995;26:1264\u20131269."},{"key":"e_1_2_4_10_1","doi-asserted-by":"publisher","DOI":"10.1002\/ccd.25030"},{"key":"e_1_2_4_11_1","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.87.4.1258"},{"key":"e_1_2_4_12_1","doi-asserted-by":"publisher","DOI":"10.1002\/ccd.1810340306"}],"container-title":["Catheterization and Cardiovascular Interventions"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.1002%2Fccd.25915","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1002\/ccd.25915","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,9,24]],"date-time":"2023-09-24T08:53:30Z","timestamp":1695545610000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1002\/ccd.25915"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2015,3,30]]},"references-count":11,"journal-issue":{"issue":"5","published-print":{"date-parts":[[2015,11]]}},"alternative-id":["10.1002\/ccd.25915"],"URL":"https:\/\/doi.org\/10.1002\/ccd.25915","archive":["Portico"],"relation":{},"ISSN":["1522-1946","1522-726X"],"issn-type":[{"value":"1522-1946","type":"print"},{"value":"1522-726X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2015,3,30]]}}}
