Eight had CTO of the right coronary artery (RCA), three circumflex (LCx), and three RCA and LCx. Left anterior descending artery was the donor artery in 13 and LCx in 1 patient. Of nine donor ischemic FFR patient's pre\u2010PCI, six reverted to non\u2010ischemic (FFR pre\u2010PCI 0.76\u2009\u00b1\u20090.04 and 0.86\u2009\u00b1\u20090.03 post\u2010PCI).

These data recommend recanalizing the CTO first whenever possible as a preferred therapeutic strategy to avoid the need for PCI to the donor artery or multivessel bypass surgery. \u00a9 2013 Wiley Periodicals, Inc.<\/jats:p><\/jats:sec>","DOI":"10.1002\/ccd.25031","type":"journal-article","created":{"date-parts":[[2013,5,22]],"date-time":"2013-05-22T14:30:24Z","timestamp":1369233024000},"source":"Crossref","is-referenced-by-count":30,"title":["Reversal of ischemia of donor artery myocardium after recanalization of a chronic total occlusion"],"prefix":"10.1002","volume":"82","author":[{"given":"Rajesh","family":"Sachdeva","sequence":"first","affiliation":[{"name":"Department of Internal Medicine Central Arkansas Veterans Healthcare System Little Rock Arkansas"},{"name":"Wellstar Cardiology North Fulton Hospital Roswell Georgia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mayank","family":"Agrawal","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine Central Arkansas Veterans Healthcare System Little Rock Arkansas"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shawn E.","family":"Flynn","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine Central Arkansas Veterans Healthcare System Little Rock Arkansas"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gerald S.","family":"Werner","sequence":"additional","affiliation":[{"name":"Medizinische Klinik I (Cardiology &amp; Intensive Care) Klinikum Darmstadt GmbH Darmstadt Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Barry F.","family":"Uretsky","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine Central Arkansas Veterans Healthcare System Little Rock Arkansas"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2013,7,3]]},"reference":[{"key":"e_1_2_6_2_1","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.87.4.1354"},{"key":"e_1_2_6_3_1","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.0000022848.92729.33"},{"key":"e_1_2_6_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijcard.2007.08.034"},{"key":"e_1_2_6_5_1","doi-asserted-by":"publisher","DOI":"10.1161\/CIRCINTERVENTIONS.109.904193"},{"key":"e_1_2_6_6_1","doi-asserted-by":"publisher","DOI":"10.1002\/ccd.22806"},{"key":"e_1_2_6_7_1","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.0000061953.72662.3A"},{"key":"e_1_2_6_8_1","doi-asserted-by":"publisher","DOI":"10.1002\/ccd.22971"},{"key":"e_1_2_6_9_1","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.102.24.2959"},{"key":"e_1_2_6_10_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jacc.2005.11.093"},{"key":"e_1_2_6_11_1","doi-asserted-by":"publisher","DOI":"10.1161\/hc4501.099316"},{"key":"e_1_2_6_12_1","doi-asserted-by":"publisher","DOI":"10.1056\/NEJMoa0807611"},{"key":"e_1_2_6_13_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jacc.2007.01.087"},{"key":"e_1_2_6_14_1","doi-asserted-by":"publisher","DOI":"10.1002\/ccd.20175"},{"key":"e_1_2_6_15_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jacc.2006.12.040"},{"key":"e_1_2_6_16_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00392-009-0013-5"}],"container-title":["Catheterization and Cardiovascular Interventions"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.1002%2Fccd.25031","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1002\/ccd.25031","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,10,6]],"date-time":"2023-10-06T08:19:36Z","timestamp":1696580376000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1002\/ccd.25031"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2013,7,3]]},"references-count":15,"journal-issue":{"issue":"4","published-print":{"date-parts":[[2013,10]]}},"alternative-id":["10.1002\/ccd.25031"],"URL":"https:\/\/doi.org\/10.1002\/ccd.25031","archive":["Portico"],"relation":{},"ISSN":["1522-1946","1522-726X"],"issn-type":[{"value":"1522-1946","type":"print"},{"value":"1522-726X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2013,7,3]]}}}
