We report a five\u2010case series in which IVL failed to achieve adequate lesion modification but was successfully augmented by the addition of one or more buddy wires. Lesion subsets included severe proximal right coronary artery calcification, IVL balloon rupture with preserved efficacy, nodular calcification refractory to atherectomy, stent underexpansion causing recurrent ST\u2010segment elevation myocardial infarction, and a concentric lesion assessed with optical coherence tomography (OCT). In the OCT\u2010guided case, buddy wire\u2013augmented IVL produced multiple additional calcium fracture lines and significant luminal gain without further balloon dilation. These findings support a hypothesis\u2010generating mechanism of mechanical\u2013acoustic coupling, whereby guidewires may facilitate localized amplification of shockwave energy. Buddy wire\u2013augmented IVL may represent a simple and effective adjunctive strategy in resistant calcified lesions.<\/jats:p>","DOI":"10.1002\/ccd.70803","type":"journal-article","created":{"date-parts":[[2026,8,11]],"date-time":"2026-08-11T15:29:41Z","timestamp":1786462181000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Buddy Wire\u2013Augmented Intravascular Lithotripsy in Refractory Calcified Coronary Lesions: A Five\u2010Case Series"],"prefix":"10.1002","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3445-0865","authenticated-orcid":false,"given":"Alfredo","family":"Marchese","sequence":"first","affiliation":[{"name":"Santa Maria Hospital GVM Care &amp; Research Bari Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1979-3130","authenticated-orcid":false,"given":"Mattia","family":"Squillace","sequence":"additional","affiliation":[{"name":"IRCCS Policlinico San Donato San Donato Milanese Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1883-8672","authenticated-orcid":false,"given":"Pierluigi","family":"Demola","sequence":"additional","affiliation":[{"name":"ASL Bari Bari Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Giuseppe","family":"Speziale","sequence":"additional","affiliation":[{"name":"Santa Maria Hospital GVM Care &amp; Research Bari Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4975-6605","authenticated-orcid":false,"given":"Francesco","family":"Bedogni","sequence":"additional","affiliation":[{"name":"IRCCS Policlinico San Donato San Donato Milanese Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0195-5063","authenticated-orcid":false,"given":"Robert J.","family":"Chilton","sequence":"additional","affiliation":[{"name":"University of Texas Health Science Center San Antonio Texas USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,8,11]]},"reference":[{"key":"e_1_2_11_2_1","doi-asserted-by":"crossref","first-page":"61","DOI":"10.1016\/j.ijcard.2016.12.150","article-title":"Two\u2010Year Outcomes After Percutaneous Coronary Intervention of Calcified Lesions with Drug\u2010Eluting Stents","volume":"231","author":"G\u00e9n\u00e9reux P.","year":"2017","journal-title":"International Journal of Cardiology"},{"issue":"4","key":"e_1_2_11_3_1","first-page":"461","article-title":"Intravascular Imaging of Coronary Calcification and its Clinical Implications","volume":"8","author":"Mintz G.
