In this projection the anatomic configuration of the aortic valve is identified, and it is possible to planimeterize the visualized aortic valve opening and accurately determine the orifice area. Fifteen individuals with congenitally deformed aortic valves with gradients ranging from trivial (&lt;10 mm Hg) to surgically significant (&gt; 60 mm Hg) were subjected to aortic orifice area measurement by orifice\u2010view aortography, and the area was compared with the peak systolic gradient and valve area. The results yielded a close correlation with the aortic valve area index as measured hydraulically or, as in three instances, directly from the surgically excised specimen (r = 0.94). A satisfactory correlation was also shown with the valve area index and the peak aortic valve gradient (r = 0.85). These observations indicate that orifice\u2010view aortography is an accurate method for the measurement of the aortic valve orifice and may be particularly useful when hydraulic measurements are unattainable or invalid.<\/jats:p>","DOI":"10.1002\/ccd.1810060204","type":"journal-article","created":{"date-parts":[[2007,3,1]],"date-time":"2007-03-01T00:51:35Z","timestamp":1172710295000},"page":"135-143","source":"Crossref","is-referenced-by-count":6,"title":["Orifice\u2010view aortography in patients with congenitally deformed aortic valves: Determination of aortic valve area"],"prefix":"10.1002","volume":"6","author":[{"suffix":"Jr.","given":"Gordon M.","family":"Folger","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hani N.","family":"Sabbah","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Daniel T.","family":"Anbe","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Paul D.","family":"Stein","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2005,10,24]]},"reference":[{"key":"e_1_2_1_2_2","doi-asserted-by":"publisher","DOI":"10.1016\/0002-9149(76)90371-4"},{"key":"e_1_2_1_3_2","first-page":"123","volume-title":"A System of Vectorcardiographic Interpretation","author":"Witham AC","year":"1975"},{"key":"e_1_2_1_4_2","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.50.1.181"},{"key":"e_1_2_1_5_2","doi-asserted-by":"publisher","DOI":"10.1016\/0002-9149(77)90196-5"},{"key":"e_1_2_1_6_2","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.55.5.773"},{"key":"e_1_2_1_7_2","doi-asserted-by":"publisher","DOI":"10.1016\/0002-8703(71)90005-6"},{"key":"e_1_2_1_8_2","doi-asserted-by":"publisher","DOI":"10.2214\/ajr.125.4.847"},{"key":"e_1_2_1_9_2","doi-asserted-by":"publisher","DOI":"10.1016\/0002-8703(51)90002-6"},{"key":"e_1_2_1_10_2","doi-asserted-by":"publisher","DOI":"10.1056\/NEJM196602102740604"},{"key":"e_1_2_1_11_2","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.29.5.787"},{"key":"e_1_2_1_12_2","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.36.1.30"},{"key":"e_1_2_1_13_2","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.23.4.509"},{"key":"e_1_2_1_14_2","first-page":"1347","article-title":"Evaluation of the degree of aortic valve stenosis by direct roentgenologic measurement of the ostium","volume":"91","author":"Friedenberg MJ","year":"1964","journal-title":"Am J Roentgenol"},{"key":"e_1_2_1_15_2","first-page":"409","article-title":"Angiocardiography in valvular heart disease: Morphologic and volumetric considerations","volume":"2","author":"Figley MM","year":"1964","journal-title":"Radiol Clin North Am"},{"key":"e_1_2_1_16_2","unstructured":"FolgerGMJr SabbahHN SteinPD:Evaluation of the anatomy of congenitally malformed aortic valves by orifice\u2010view aortography.
