By offering a unique volumetric perspective, 3DE allows a comprehensive visualization of the entire MV apparatus, enhancing the capacity to appreciate anatomical and functional details.<\/jats:p>\n                  <jats:p>In mitral regurgitation (MR), 3DE adds pivotal information about leaflet morphology, annular geometry, and sub-valvular structures across all Carpentier subtypes, playing a central role in surgical and percutaneous procedural planning. 3D colour-mode imaging improves spatial localization of regurgitant jets and enables advanced MR quantification techniques. Specifically, 3D proximal isovelocity surface area and 3D vena contracta area offer improved accuracy over 2D methods, particularly in functional MR, and in multiple or complex jets. Additionally, the 3D indirect volumetric method and emerging semi-automated software are further tools for MR quantification. In mitral stenosis, 3D planimetry via transthoracic and transoesophageal echocardiography provides more accurate and reproducible measurements of the MV area compared with 2D, especially in challenging anatomies or suboptimal imaging planes. 3DE, especially using the transoesophageal approach, also improves commissural evaluation, which is essential for patient selection for percutaneous valvuloplasty. Overall, 3DE has redefined MV imaging by offering unparalleled anatomical and quantitative assessment. Its integration into routine clinical practice is critical for modern echocardiography and should be considered a core competency for cardiovascular imaging specialists.<\/jats:p>","DOI":"10.1093\/ehjimp\/qyaf128","type":"journal-article","created":{"date-parts":[[2025,10,17]],"date-time":"2025-10-17T12:10:54Z","timestamp":1760703054000},"source":"Crossref","is-referenced-by-count":6,"title":["Three-dimensional assessment of the mitral valve in clinical practice"],"prefix":"10.1093","volume":"3","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2052-4891","authenticated-orcid":false,"given":"Tommaso","family":"Viva","sequence":"first","affiliation":[{"name":"Department of Clinical Cardiology and Cardiovascular Imaging, IRCCS Galeazzi-Sant\u2019Ambrogio Hospital , Milan ,","place":["Italy"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Corrado","family":"Fiore","sequence":"additional","affiliation":[{"name":"Department of Cardiology, Citt\u00e0 di Lecce Hospital, GVM Care & Research , Lecce ,","place":["Italy"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0804-8194","authenticated-orcid":false,"given":"Patrizio","family":"Lancellotti","sequence":"additional","affiliation":[{"name":"Department of Cardiology, University of Li\u00e8ge Hospital, GIGA Institute Cardiovascular Science & Metabolism, CHU Sart Tilman , Domaine Universitaire du Sart Tilman\u2014B.35, Sart Tilman, Li\u00e8ge 4000 ,","place":["Belgium"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2025,10,19]]},"reference":[{"key":"2025112813024180000_qyaf128-B1","doi-asserted-by":"crossref","first-page":"589","DOI":"10.1161\/01.CIR.80.3.589","article-title":"Three-dimensional echocardiographic reconstruction of the mitral valve, with implications for the diagnosis of mitral valve prolapse","volume":"80","author":"Levine","year":"1989","journal-title":"Circulation"},{"key":"2025112813024180000_qyaf128-B2","doi-asserted-by":"crossref","unstructured":"Suma S .
