Her symptoms had worsened over several months, with multiple admissions at other institutions with treatment for both COPD exacerbation and heart failure. Transoesophageal echocardiogram demonstrated preserved ejection fraction, normal functioning aortic valve, and dysfunctional mitral prosthesis with severe stenosis (mean gradient 13\u2009mmHg) and moderate-severe regurgitation. After a multi-disciplinary heart team discussion, the patient underwent a transcatheter MVIV implantation. During the case, inability in advancing the transcatheter heart valve (THV) across interatrial septum despite adequate septal balloon pre-dilation was successfully managed with the support of a stiff \u2018buddy wire\u2019 anchored in the left upper pulmonary vein using the same septal puncture. The patient tolerated the procedure well and was discharged home.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Discussion<\/jats:title>\n                  <jats:p>Operators should be aware of potential strategies to advance the THV when difficulty is encountered in crossing the atrial septum despite adequate septal preparation. One such strategy is the use of stiff \u2018buddy wire\u2019 for support which avoids the need for more aggressive septal dilatation.<\/jats:p>\n               <\/jats:sec>","DOI":"10.1093\/ehjcr\/ytaa373","type":"journal-article","created":{"date-parts":[[2020,11,9]],"date-time":"2020-11-09T23:42:48Z","timestamp":1604965368000},"page":"1-4","source":"Crossref","is-referenced-by-count":3,"title":["Case report: Buddy wire technique to facilitate atrial septal crossing during transcatheter transseptal mitral valve implantation"],"prefix":"10.1093","volume":"4","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0310-6567","authenticated-orcid":false,"given":"Ashvarya","family":"Mangla","sequence":"first","affiliation":[{"name":"Division of Cardiology, Rush University Medical Center, 1717 W Congress parkway, Suite 313, 3-Kellogg, Chicago, IL, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8180-3160","authenticated-orcid":false,"given":"Ameer","family":"Musa","sequence":"additional","affiliation":[{"name":"Division of Cardiology, Rush University Medical Center, 1717 W Congress parkway, Suite 313, 3-Kellogg, Chicago, IL, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Clifford J","family":"Kavinsky","sequence":"additional","affiliation":[{"name":"Division of Cardiology, Rush University Medical Center, 1717 W Congress parkway, Suite 313, 3-Kellogg, Chicago, IL, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6012-9648","authenticated-orcid":false,"given":"Hussam S","family":"Suradi","sequence":"additional","affiliation":[{"name":"Division of Cardiology, Rush University Medical Center, 1717 W Congress parkway, Suite 313, 3-Kellogg, Chicago, IL, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2020,11,9]]},"reference":[{"key":"2021010812214212600_ytaa373-B1","doi-asserted-by":"crossref","first-page":"e008425","DOI":"10.1161\/CIRCINTERVENTIONS.119.008425","article-title":"Thirty-day outcomes of transcatheter mitral valve replacement for degenerated mitral bioprostheses (valve-in-valve), failed surgical rings (valve-in-ring), and native valve with severe mitral annular calcification (valve-in-mitral annular calcification) in the United States: data from the Society of Thoracic Surgeons\/American College of Cardiology\/Transcatheter Valve Therapy Registry","volume":"13","author":"Guerrero","year":"2020","journal-title":"Circ Cardiovasc Interv"},{"key":"2021010812214212600_ytaa373-B2","doi-asserted-by":"crossref","first-page":"E185","DOI":"10.1002\/ccd.27128","article-title":"Transseptal transcatheter mitral valve-in-valve: a step by step guide from preprocedural planning to postprocedural care","volume":"92","author":"Guerrero","year":"2018","journal-title":"Cathet Cardiovasc Intervent"},{"key":"2021010812214212600_ytaa373-B3","doi-asserted-by":"crossref","first-page":"243","DOI":"10.1253\/circj.CJ-18-0413","article-title":"Usefulness of buddy wire technique during transcatheter transseptal mitral valve implantation in degenerated mitral bioprosthesis","volume":"83","author":"Hachinohe","year":"2018","journal-title":"Circ J"}],"container-title":["European Heart Journal -
