A cortisol gradient of \u22652.0 between adrenal vein and a femoral vein sample was used as success criterion.

The increase in overall success was due to an increase in successful right AVS (85 vs 62% before introduction of RCA; <jats:italic>P<\/jats:italic>=0.02) and a training effect (<jats:italic>P<\/jats:italic>=0.024 for trend).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>RCA during AVS are useful in centers with an initially low AVS success rate.<\/jats:p><\/jats:sec>","DOI":"10.1530\/eje-11-0287","type":"journal-article","created":{"date-parts":[[2011,5,21]],"date-time":"2011-05-21T02:04:17Z","timestamp":1305943457000},"page":"301-306","update-policy":"https:\/\/doi.org\/10.1530\/crossmarkpolicy-1","source":"Crossref","is-referenced-by-count":95,"title":["Adrenal vein sampling using rapid cortisol assays in primary aldosteronism is useful in centers with low success rates"],"prefix":"10.1093","volume":"165","author":[{"given":"Matthias J","family":"Betz","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christoph","family":"Degenhart","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Evelyn","family":"Fischer","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anna","family":"Pallauf","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Volker","family":"Brand","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ulrich","family":"Linsenmaier","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Felix","family":"Beuschlein","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Martin","family":"Bidlingmaier","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Martin","family":"Reincke","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","reference":[{"issue":"11","key":"1_22950147","doi-asserted-by":"publisher","first-page":"2293","DOI":"10.1016\/j.jacc.2006.07.059","volume":"48","year":"2006","journal-title":"Journal of the American College of Cardiology","ISSN":"https:\/\/id.crossref.org\/issn\/0735-1097","issn-type":"print"},{"issue":"9","key":"2_31291984","doi-asserted-by":"publisher","first-page":"3266","DOI":"10.1210\/jc.2008-0104","volume":"93","year":"2008","journal-title":"Journal of Clinical Endocrinology &amp; Metabolism","ISSN":"https:\/\/id.crossref.org\/issn\/0021-972X","issn-type":"print"},{"issue":"1","key":"3_43911605","doi-asserted-by":"publisher","first-page":"13","DOI":"10.1016\/j.amjhyper.2005.05.013","volume":"19","year":"2006","journal-title":"American Journal of Hypertension","ISSN":"https:\/\/id.crossref.org\/issn\/0895-7061","issn-type":"print"},{"issue":"2","key":"4_22320446","doi-asserted-by":"publisher","first-page":"232","DOI":"10.1161\/01.HYP.0000230444.01215.6a","volume":"48","year":"2006","journal-title":"Hypertension","ISSN":"https:\/\/id.crossref.org\/issn\/0194-911X","issn-type":"print"},{"issue":"5","key":"5_35431411","doi-asserted-by":"publisher","first-page":"329","DOI":"10.7326\/0003-4819-151-5-200909010-00007","volume":"151","author":"Kempers","year":"2009","journal-title":"Annals of Internal Medicine","ISSN":"https:\/\/id.crossref.org\/issn\/0003-4819","issn-type":"print"},{"issue":"2","key":"6_35642853","doi-asserted-by":"publisher","first-page":"146","DOI":"10.1111\/j.1365-2265.2009.03714.x","volume":"72","author":"Stewart","year":"2010","journal-title":"Clinical endocrinology","ISSN":"https:\/\/id.crossref.org\/issn\/0300-0664","issn-type":"print"},{"issue":"5","key":"7_39410687","doi-asserted-by":"publisher","first-page":"990","DOI":"10.1161\/HYPERTENSIONAHA.110.168484","volume":"57","year":"2011","journal-title":"Hypertension","ISSN":"https:\/\/id.crossref.org\/issn\/0194-911X","issn-type":"print"},{"issue":"3","key":"8_5570379","doi-asserted-by":"publisher","first-page":"187","DOI":"10.1088\/0143-0815\/10\/3\/001","volume":"10","author":"Williams","year":"1989","journal-title":"Clinical physics and physiological measurement : an official journal of the Hospital Physicists' Association, Deutsche Gesellschaft f&#x00A0;&#x00A0;r Medizinische Physik and the European Federation of Organisations for Medical Physics","ISSN":"https:\/\/id.crossref.org\/issn\/0143-0815","issn-type":"print"},{"issue":"6","key":"9_37163478","doi-asserted-by":"publisher","first-page":"411","DOI":"10.1055\/s-0030-1252060","volume":"42","author":"Auchus","year":"2010","journal-title":"Hormone and metabolic research.
