Tricuspid regurgitation: when is it time for surgery?

Introduction: The interest in tricuspid regurgitation (TR) surgical treatment has grown in the last years, mostly motivated by the trend for early intervention and the development of minimally invasive surgical techniques. Despite this, there is still a lack of evidence regarding when to intervene in functional tricuspid regurgitation outside the context of left-sided valve surgery and when is the best time to approach primary tricuspid regurgitation. Areas covered: Herein, we present the state-of-the-art in tricuspid regurgitation surgical intervention, covering indications, optimum time, surgical options, and outcomes, as well as the role of transcatheter tricuspid valve intervention in the current era. Expert opinion: Current evidence support that the indications and timing of tricuspid valve invasive management should be centered on a range of factors, including patients' characteristics, disease stage, and anatomical considerations. Early intervention, before severe right ventricle dysfunction and pulmonary hypertension, seems to results in better postoperative outcomes. Transcatheter techniques are arising as potential alternatives for inoperable and high-risk patients.
