Unfortunately, many patients with advanced right-sided heart failure are not referred for isolated tricuspid valve (TV) surgery in a timely manner. This delayed referral has resulted in a high in-hospital mortality rate and significant undertreatment. Fortunately, transcatheter TV intervention (TTVI) has emerged as a safe and effective alternative to surgery, successfully reducing TR severity and improving patients’ quality of life. Current guidelines emphasize the importance of assessing TR severity and its impact on the right heart chambers for selecting the appropriate intervention. However, the echocardiographic assessment of both right chambers and TV anatomy, along with TR severity, poses specific challenges, leading to the underestimation of TR severity. Recently, three-dimensional echocardiography has become crucial to enhance the characterization of TR severity. Moreover, it is essential to evaluate residual TR after TTVI to gauge the intervention’s success and predict the patient’s prognosis. This review provides a thorough evaluation of the echocardiographic parameters used to assess TR severity before and after TTVI. It presents a critical analysis of the accuracy and reliability of these parameters, highlighting their strengths and limitations to establish standardized diagnostic criteria and treatment protocols for TR, which will inform clinical decision-making and improve patient outcomes.</div></div>","PeriodicalId":50011,"journal":{"name":"Journal of the American Society of Echocardiography","volume":null,"pages":null},"PeriodicalIF":5.4,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141728052","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
