This method assumes geometries and can be misleading. In contrast, three\u2010dimensional (3D) echocardiography directly measures flow volumes and does not assume geometries, which allows for more accurate MR<\/jats:styled-content> evaluation.<\/jats:p><\/jats:sec>Aims<\/jats:title>To report the 3D transesophageal echocardiography (3DTEE<\/jats:styled-content>) feasibility for MR<\/jats:styled-content> quantification and evaluate its concordance with 2D echo.<\/jats:p><\/jats:sec>Methods<\/jats:title>Twenty\u2010seven consecutive patients undergoing 2D and 3DTEE<\/jats:styled-content> for presurgical MR<\/jats:styled-content> evaluation were studied prospectively. MR<\/jats:styled-content> quantification was performed by classical 2D methods based on PFC<\/jats:styled-content>. Diameters of the VC<\/jats:styled-content> in orthogonal planes by 3DTEE<\/jats:styled-content> were estimated, establishing the VC<\/jats:styled-content> sphericity index as well as VC<\/jats:styled-content> area (VCA<\/jats:styled-content>) by direct planimetry.

An adequate concordance between VC<\/jats:styled-content> measurements by 2D methods (TTE<\/jats:styled-content> and TEE<\/jats:styled-content>) was observed; however, there was a poor correlation when compared with 3DTEE<\/jats:styled-content>. The sphericity index of the VC<\/jats:styled-content> was: 2.08 (\u00b10. 72), reflecting a noncircular VC<\/jats:styled-content>.<\/jats:p><\/jats:sec>Conclusions<\/jats:title>3DTEE<\/jats:styled-content> is a feasible method for the assessment of the MR<\/jats:styled-content> true morphology, allowing a better quantification of MR<\/jats:styled-content> without assuming any geometry. This method revealed the presence of multiple jets, potentially improving MR<\/jats:styled-content> evaluation and leading to changes in medical decision when compared to 2D echo assessment.<\/jats:p><\/jats:sec>","DOI":"10.1111\/echo.13395","type":"journal-article","created":{"date-parts":[[2016,10,11]],"date-time":"2016-10-11T16:34:31Z","timestamp":1476203671000},"page":"87-93","source":"Crossref","is-referenced-by-count":2,"title":["True morphology of mitral regurgitant flow assessed by three\u2010dimensional transesophageal echocardiography"],"prefix":"10.1111","volume":"34","author":[{"given":"Martin","family":"Lombardero","sequence":"first","affiliation":[{"name":"Cardiovascular Imaging Department Sanatorio de la Trinidad Palermo CABA Argentina"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ruth","family":"Henquin","sequence":"additional","affiliation":[{"name":"Cardiovascular Imaging Department Sanatorio de la Trinidad Palermo CABA Argentina"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gabriel","family":"Perea","sequence":"additional","affiliation":[{"name":"Cardiovascular Imaging Department Sanatorio de la Trinidad Palermo CABA Argentina"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mariana","family":"Corneli","sequence":"additional","affiliation":[{"name":"Cardiovascular Imaging Department Sanatorio de la Trinidad Palermo CABA Argentina"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Carlos","family":"Izurieta","sequence":"additional","affiliation":[{"name":"Cardiovascular Imaging Department Sanatorio de la Trinidad Palermo CABA Argentina"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2016,10,4]]},"reference":[{"key":"e_1_2_8_2_1","doi-asserted-by":"publisher","DOI":"10.1093\/ejechocard\/jeq031"},{"key":"e_1_2_8_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0894-7317(03)00335-3"},{"key":"e_1_2_8_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jacc.2008.04.038"},{"key":"e_1_2_8_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.echo.2011.06.011"},{"key":"e_1_2_8_6_1","doi-asserted-by":"publisher","DOI":"10.1161\/CIRCIMAGING.110.961649"},{"key":"e_1_2_8_7_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.echo.2006.09.006"},{"key":"e_1_2_8_8_1","doi-asserted-by":"publisher","DOI":"10.1152\/ajpheart.00275.2011"},{"key":"e_1_2_8_9_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.echo.2008.02.003"},{"key":"e_1_2_8_10_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jcmg.2012.03.008"},{"key":"e_1_2_8_11_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.echo.2014.10.003"},{"key":"e_1_2_8_12_1","first-page":"118","article-title":"Where is the effective mitral orifice?
