There is an increasing recognition of a subgroup of patients with isolated TR in the absence of other associated cardiac abnormalities. Left untreated isolated TR significantly worsens survival. Stand-alone surgery for isolated TR is rarely performed due to an average operative mortality of 8%\u201310%\u2009and a paucity of data demonstrating improved survival. When surgery is performed, valve repair may be preferred over replacement; however, there is a risk of significant recurrent regurgitation after repair. Existing society guidelines do not fully address the management of isolated TR. We propose that patients at low operative risk with symptomatic severe isolated TR and no reversible cause undergo surgery prior to the onset of right ventricular dysfunction and end-organ damage. For patients at increased surgical risk novel percutaneous interventions may offer an alternative treatment but further research is needed. Significant knowledge gaps remain and future research is needed to define operative outcomes and provide comparative data for medical and surgical therapy.<\/jats:p>","DOI":"10.1136\/heartjnl-2017-311586","type":"journal-article","created":{"date-parts":[[2017,12,11]],"date-time":"2017-12-11T12:15:17Z","timestamp":1512994517000},"page":"798-806","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":207,"title":["Isolated tricuspid regurgitation: outcomes and therapeutic interventions"],"prefix":"10.1136","volume":"104","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1513-0169","authenticated-orcid":false,"given":"Erin A","family":"Fender","sequence":"first","affiliation":[{"name":"Department of Cardiovascular Disease, Mayo Clinic, Rochester, Minnesota, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chad J","family":"Zack","sequence":"additional","affiliation":[{"name":"Department of Cardiovascular Disease, Mayo Clinic, Rochester, Minnesota, USA"},{"name":"Division of Cardiology, Duke University, Durham, NC, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rick A","family":"Nishimura","sequence":"additional","affiliation":[{"name":"Department of Cardiovascular Disease, Mayo Clinic, Rochester, Minnesota, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[2017,12,11]]},"reference":[{"key":"2025092101374101000_104.10.798.1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jtcvs.2011.07.004"},{"key":"2025092101374101000_104.10.798.2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jtcvs.2006.08.049"},{"key":"2025092101374101000_104.10.798.3","doi-asserted-by":"publisher","DOI":"10.1016\/S0002-9149(98)01064-9"},{"key":"2025092101374101000_104.10.798.4","doi-asserted-by":"publisher","DOI":"10.1016\/j.jacc.2003.09.036"},{"key":"2025092101374101000_104.10.798.5","doi-asserted-by":"publisher","DOI":"10.1016\/j.jcmg.2014.07.018"},{"key":"2025092101374101000_104.10.798.6","doi-asserted-by":"publisher","DOI":"10.1016\/S0002-9149(98)00567-0"},{"key":"2025092101374101000_104.10.798.7","doi-asserted-by":"publisher","DOI":"10.1016\/j.jacc.2017.02.055"},{"key":"2025092101374101000_104.10.798.8","doi-asserted-by":"publisher","DOI":"10.1016\/j.echo.2006.09.013"},{"key":"2025092101374101000_104.10.798.9","doi-asserted-by":"publisher","DOI":"10.1136\/heartjnl-2013-304673"},{"key":"2025092101374101000_104.10.798.10","doi-asserted-by":"crossref","unstructured":"Utsunomiya H , Itabashi Y , Mihara H , et al .
