On the basis of anatomic location these lesions can be divided into supravalvular, valvular, and subvalvular stenosis, and valvular lesions further can be subdivided into congenital and acquired categories. Temporary cardiopulmonary bypass with a pump oxygenator provides sustained support of the circulation for operation, while surgical technics employed are selected on the basis of etiology and location of the lesion. Experience gained in operations on 296 patients with obstructive lesions of the left ventricular outflow tract since 1956 now has demonstrated that these operations usually can be performed with acceptable risk and with excellent functional results.<\/jats:p>","DOI":"10.1161\/01.cir.31.4.612","type":"journal-article","created":{"date-parts":[[2012,6,11]],"date-time":"2012-06-11T23:27:25Z","timestamp":1339457245000},"page":"612-621","update-policy":"https:\/\/doi.org\/10.1161\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":26,"title":["Obstructive Lesions of the Left Ventricular Outflow Tract"],"prefix":"10.1161","volume":"31","author":[{"given":"DENTON A.","family":"COOLEY","sequence":"first","affiliation":[{"name":"From the Cora and Webb Mading Department of Surgery, Baylor University College of Medicine, and the Cardiovascular Surgery Services of the St. Luke's Episcopal, Methodist, and Ben Taub General Hospitals, Houston, Texas."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"suffix":"JR.","given":"ARTHUR C.","family":"BEALL","sequence":"additional","affiliation":[{"name":"From the Cora and Webb Mading Department of Surgery, Baylor University College of Medicine, and the Cardiovascular Surgery Services of the St. Luke's Episcopal, Methodist, and Ben Taub General Hospitals, Houston, Texas."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"GRADY L.","family":"HALLMAN","sequence":"additional","affiliation":[{"name":"From the Cora and Webb Mading Department of Surgery, Baylor University College of Medicine, and the Cardiovascular Surgery Services of the St. Luke's Episcopal, Methodist, and Ben Taub General Hospitals, Houston, Texas."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"DONALD L.","family":"BRICKER","sequence":"additional","affiliation":[{"name":"From the Cora and Webb Mading Department of Surgery, Baylor University College of Medicine, and the Cardiovascular Surgery Services of the St. Luke's Episcopal, Methodist, and Ben Taub General Hospitals, Houston, Texas."}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"276","container-title":["Circulation"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.ahajournals.org\/doi\/pdf\/10.1161\/01.CIR.31.4.612","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2024,5,12]],"date-time":"2024-05-12T14:13:44Z","timestamp":1715523224000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.ahajournals.org\/doi\/10.1161\/01.CIR.31.4.612"}},"subtitle":["Surgical Treatment"],"short-title":[],"issued":{"date-parts":[[1965,4]]},"references-count":0,"journal-issue":{"issue":"4","published-print":{"date-parts":[[1965,4]]}},"alternative-id":["10.1161\/01.CIR.31.4.612"],"URL":"https:\/\/doi.org\/10.1161\/01.cir.31.4.612","relation":{},"ISSN":["0009-7322","1524-4539"],"issn-type":[{"value":"0009-7322","type":"print"},{"value":"1524-4539","type":"electronic"}],"subject":[],"published":{"date-parts":[[1965,4]]},"assertion":[{"value":"1965-04-01","order":2,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}]}}
