Spatial and temporal resolution of 3D echocardiography enables 3D printing of valve morphology. However, non\u2010linearity, angle dependence, speckle, blur, and resampling complicate segmentation compared to computed tomography (CT) and magnetic resonance imaging (MRI). A case of complex mitral valve disease in a pediatric patient is therefore presented to illustrate the technical challenges of segmentation and 3D printing from echocardiographic data.<\/jats:p>","DOI":"10.1111\/echo.15239","type":"journal-article","created":{"date-parts":[[2021,10,31]],"date-time":"2021-10-31T05:49:26Z","timestamp":1635659366000},"page":"1978-1983","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Three\u2010dimensional modeling of the mitral valve for surgical planning in a pediatric patient: A case\u2010based discussion of the technical challenges of segmentation and printing from 3D transthoracic echocardiographic datasets"],"prefix":"10.1111","volume":"38","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4432-0578","authenticated-orcid":false,"given":"Gregory M.","family":"Sturgeon","sequence":"first","affiliation":[{"name":"Duke Children's Pediatric &amp; Congenital Heart Center Duke University Medical Center  Durham North Carolina USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nicholas D.","family":"Andersen","sequence":"additional","affiliation":[{"name":"Duke Children's Pediatric &amp; Congenital Heart Center Duke University Medical Center  Durham North Carolina USA"},{"name":"Division of Cardiovascular and Thoracic Surgery Duke University Medical Center  Durham North Carolina USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michael J.","family":"Campbell","sequence":"additional","affiliation":[{"name":"Duke Children's Pediatric &amp; Congenital Heart Center Duke University Medical Center  Durham North Carolina USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Piers C.
