Vascular anatomic variants were classified according to 10 categories and sub\u2010grouped according to the ABC classification (A: radial\u2010brachial arterial axis; B: axillary\u2010subclavian\u2010anonymous axis; C: aortic arch). Primary study end\u2010point was failure of trans\u2010radial approach (necessity to cross\u2010over to another approach to complete the procedure).<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Three thousand four hundred seventy\u2010seven consecutive radial procedures were considered. Anatomic variants were diagnosed in 308 procedures (8.8%): A variants: 7.2%, B variants: 1.9%; C variants: 0.3%. Failure occurred in 2.0% of procedures. Failure rate was 0.7% in the absence of variants vs.15.2% in the presence of any variant (<jats:italic>P<\/jats:italic> &lt; 0.0001, OR 27.7, 95%CI 16.3\u201346.9). Each of the 10 variants was significantly associated with increased failure rate. Each of the three level\u2010subgroups of variants was significantly associated to the risk of failure (failure 14.7% in A level, 13.9% in B level, 33.3% in C level; <jats:italic>P<\/jats:italic> &lt; 0.0001 vs. absence of variants).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Failure of trans\u2010radial procedures is associated to anatomic variants located from the wrist to the aorta. The \u201coperative\u201d ABC classification of anatomic variants is useful not only to categorize these anatomic variants, but also to predict the risk of failure of trans\u2010radial approach. \u00a9 2012 Wiley Periodicals, Inc.<\/jats:p><\/jats:sec>","DOI":"10.1002\/ccd.24360","type":"journal-article","created":{"date-parts":[[2012,3,16]],"date-time":"2012-03-16T19:35:39Z","timestamp":1331926539000},"page":"298-303","source":"Crossref","is-referenced-by-count":27,"title":["Impact of radial\u2010to\u2010aorta vascular anatomical variants on risk of failure in trans\u2010radial coronary procedures"],"prefix":"10.1002","volume":"80","author":[{"given":"Francesco","family":"Burzotta","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Marta Francesca","family":"Brancati","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Carlo","family":"Trani","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Antonella","family":"Tommasino","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Italo","family":"Porto","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Giampaolo","family":"Niccoli","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Antonio Maria","family":"Leone","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Valentina","family":"Coluccia","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Paola","family":"Di Noi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Filippo","family":"Crea","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2012,5,2]]},"reference":[{"key":"e_1_2_6_2_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jacc.2004.04.034"},{"key":"e_1_2_6_3_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.ahj.2008.08.023"},{"key":"e_1_2_6_4_2","doi-asserted-by":"publisher","DOI":"10.1002\/ccd.22126"},{"key":"e_1_2_6_5_2","doi-asserted-by":"publisher","DOI":"10.1002\/ccd.22091"},{"key":"e_1_2_6_6_2","doi-asserted-by":"publisher","DOI":"10.1002\/ccd.22014"},{"key":"e_1_2_6_7_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.amjcard.2011.03.022"},{"key":"e_1_2_6_8_2","doi-asserted-by":"publisher","DOI":"10.1002\/(SICI)1522-726X(200004)49:4<357::AID-CCD1>3.0.CO;2-Z"},{"key":"e_1_2_6_9_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijcard.2004.03.061"},{"key":"e_1_2_6_10_2","doi-asserted-by":"publisher","DOI":"10.1002\/ccd.20732"},{"key":"e_1_2_6_11_2","doi-asserted-by":"publisher","DOI":"10.1136\/hrt.2008.150474"},{"key":"e_1_2_6_12_2","doi-asserted-by":"publisher","DOI":"10.1002\/1522-726X(200010)51:2<250::AID-CCD24>3.0.CO;2-0"},{"key":"e_1_2_6_13_2","first-page":"43","article-title":"Brachial and antebrachial arterial patterns;
