There is limited modern literature describing methods to overcome these challenges and reduce TRA failure.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>A number of primary subclavian, innominate, and aortic arch anatomical challenges are identified and management techniques to overcome them are discussed.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Subclavian, innominate, and aortic arch anatomical challenges can be divided into five subsets, including (1) tortuosity, (2) loop, (3) stenosis, (4) congenital aberrancy, and (5) combined challenges. In depth discussion with supportive examples for the identification and management of these challenges are provided.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Despite lower rates of bleeding and vascular complications as compared to transfemoral approach, the adoption of TRA has been relatively slow in part due to frustration from operator failure during the learning curve. Anatomical challenges of subclavian, innominate, and aortic arch regions play an important role in TRA procedural failure. Using a simple, conceptual, framework to classify the anatomical or functional problem and then applying a logical approach to these challenges can facilitate management and augment operator success rates for TRA. \u00a9 2014 Wiley Periodicals, Inc.<\/jats:p><\/jats:sec>","DOI":"10.1002\/ccd.25418","type":"journal-article","created":{"date-parts":[[2014,2,10]],"date-time":"2014-02-10T04:04:39Z","timestamp":1392005079000},"page":"224-235","source":"Crossref","is-referenced-by-count":24,"title":["Working through challenges of subclavian, innominate, and aortic arch regions during transradial approach"],"prefix":"10.1002","volume":"84","author":[{"given":"Tejas","family":"Patel","sequence":"first","affiliation":[{"name":"Apex Heart Institute Ahmedabad India"},{"name":"Department of Cardiology Sheth V.S.
