Doppler color-flow imaging displays the transatrial jet, providing a new dimension with the potential capability of quantifying left-to-right shunt size. Twenty-three patients with atrial septal defect were studied by color-flow imaging and cardiac catheterization. The defect size measured by two-dimensional echocardiography, the maximal color-flow jet width in the atrial septum, and the maximal color-flow jet area in the right atrium were correlated with cardiac catheterization-derived left-to-right shunt size. Correlation coefficients were 0.57 (p less than 0.01), 0.67 (p less than 0.001), and 0.65 (p less than 0.01), respectively. Atrial septal color-flow jet width distinguished patients with less than a 2:1 left-to-right shunt size ratio (eight patients, jet width less than 15 mm in in all) from patients with greater than a 2:1 left-to-right shunt size ratio (15 patients, jet width greater than 15 mm in all). These results indicate that Doppler color-flow imaging can distinguish left-to-right shunt size in atrial septal defect accurately enough to influence decisions with regard to subsequent patient management.<\/jats:p>","DOI":"10.1161\/01.cir.78.3.522","type":"journal-article","created":{"date-parts":[[2011,6,17]],"date-time":"2011-06-17T20:29:13Z","timestamp":1308342553000},"page":"522-528","update-policy":"https:\/\/doi.org\/10.1161\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":47,"title":["Doppler color-flow imaging assessment of shunt size in atrial septal defect."],"prefix":"10.1161","volume":"78","author":[{"given":"C","family":"Pollick","sequence":"first","affiliation":[{"name":"Department of Medicine, Toronto Western Hospital, Ontario, Canada."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"H","family":"Sullivan","sequence":"additional","affiliation":[{"name":"Department of Medicine, Toronto Western Hospital, Ontario, Canada."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"B","family":"Cujec","sequence":"additional","affiliation":[{"name":"Department of Medicine, Toronto Western Hospital, Ontario, Canada."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"S","family":"Wilansky","sequence":"additional","affiliation":[{"name":"Department of Medicine, Toronto Western Hospital, Ontario, Canada."}],"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.78.3.522","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2024,5,12]],"date-time":"2024-05-12T14:59:51Z","timestamp":1715525991000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.ahajournals.org\/doi\/10.1161\/01.CIR.78.3.522"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[1988,9]]},"references-count":0,"journal-issue":{"issue":"3","published-print":{"date-parts":[[1988,9]]}},"alternative-id":["10.1161\/01.CIR.78.3.522"],"URL":"https:\/\/doi.org\/10.1161\/01.cir.78.3.522","relation":{},"ISSN":["0009-7322","1524-4539"],"issn-type":[{"value":"0009-7322","type":"print"},{"value":"1524-4539","type":"electronic"}],"subject":[],"published":{"date-parts":[[1988,9]]},"assertion":[{"value":"1988-09-01","order":2,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}]}}
