Tricuspid Regurgitation: Predicting the Need for Intervention, Procedural Success, and Recurrence of Disease.

Interest in tricuspid valve pathology has rapidly expanded in response to reported poor clinical outcome for functional tricuspid regurgitation and the limited indications and options for treatment. In the past few years, different transcatheter technologies have emerged as alternatives to conventional surgery to serve this untreated high-risk population. In this review, the authors explore the indications for intervention in tricuspid regurgitation according to current guidelines, the published research to support the expansion of these indications including the role of transcatheter interventions, and the risk factors for therapy failure, which may help define the appropriate patient population for treatment.
