Left ITA grafting was performed in 384 patients, and in 369, the in situ left ITA was anastomosed to the left anterior descending coronary artery using standard methods. Early postoperative angiography was performed in 381 patients. The RITA was occluded in 4 patients, and string-like artery and significant stenosis were present in 11 and 7 patients, respectively; RITA graft patency was thus 94.1%. Of the preoperative variables and angiographic data, simple and multiple logistic regression analyses identified decreased severity of native stenosis, diffuse sclerosis of native vessels, and residual side branches of the ITA as independent predictors of nonfunctional grafts. The method of ITA grafting did not influence the patency of the graft.\n          <\/jats:p>\n          <jats:p>\n            <jats:italic>Conclusions<\/jats:italic>\n            \u2014The excellent patency rate demonstrated by this study, the largest angiographic study to date of RITA grafting via the transverse sinus, indicates that this technique can provide reliable revascularization of the left ventricle and that it has the potential to be applied to a wide variety of patients with diseased circumflex arteries.\n          <\/jats:p>","DOI":"10.1161\/01.cir.101.6.640","type":"journal-article","created":{"date-parts":[[2012,6,12]],"date-time":"2012-06-12T00:42:29Z","timestamp":1339461749000},"page":"640-646","update-policy":"https:\/\/doi.org\/10.1161\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":18,"title":["Analysis by Early Angiography of Right Internal Thoracic Artery Grafting Via the Transverse Sinus"],"prefix":"10.1161","volume":"101","author":[{"given":"Masashi","family":"Ura","sequence":"first","affiliation":[{"name":"From the Departments of Cardiovascular Surgery and Cardiology (S.O., K.N.), Kumamoto Central Hospital, Japan."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ryuzo","family":"Sakata","sequence":"additional","affiliation":[{"name":"From the Departments of Cardiovascular Surgery and Cardiology (S.O., K.N.), Kumamoto Central Hospital, Japan."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yoshihiro","family":"Nakayama","sequence":"additional","affiliation":[{"name":"From the Departments of Cardiovascular Surgery and Cardiology (S.O., K.N.), Kumamoto Central Hospital, Japan."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yoshio","family":"Arai","sequence":"additional","affiliation":[{"name":"From the Departments of Cardiovascular Surgery and Cardiology (S.O., K.N.), Kumamoto Central Hospital, Japan."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shuichi","family":"Oshima","sequence":"additional","affiliation":[{"name":"From the Departments of Cardiovascular Surgery and Cardiology (S.O., K.N.), Kumamoto Central Hospital, Japan."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Katsuo","family":"Noda","sequence":"additional","affiliation":[{"name":"From the Departments of Cardiovascular Surgery and Cardiology (S.O., K.N.), Kumamoto Central Hospital, Japan."}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"276","reference":[{"key":"e_1_3_1_1_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0003-4975(10)64200-2"},{"key":"e_1_3_1_2_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0022-5223(95)70057-9"},{"key":"e_1_3_1_3_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0022-5223(96)70059-4"},{"key":"e_1_3_1_4_2","doi-asserted-by":"publisher","DOI":"10.1016\/0003-4975(96)00080-X"},{"key":"e_1_3_1_5_2","doi-asserted-by":"publisher","DOI":"10.1161\/circ.98.19.2043"},{"key":"e_1_3_1_6_2","doi-asserted-by":"publisher","DOI":"10.1056\/NEJM198601023140101"},{"key":"e_1_3_1_7_2","doi-asserted-by":"publisher","DOI":"10.1001\/jama.1981.03320190039024"},{"key":"e_1_3_1_8_2","first-page":"393","volume":"96","year":"1998","unstructured":"Suma H, Takeuchi A, Kondo K, Maeda M, Fukumoto H, Kimura H, Sato H, Hasegawa S.
