Why the study?
Most patients with severe tricuspid regurgitation remain untreated due to high surgical mortality, making transcatheter tricuspid valve interventions an emerging alternative to address this unmet need.
This review summarizes the emerging transcatheter repair and replacement options for patients with severe tricuspid regurgitation who are at high surgical risk.
May expand options for high-risk severe tricuspid regurgitation; leaves open need for randomized efficacy and safety data.
: Tricuspid regurgitation, either isolated or associated with left-valve disease, has a strong impact on outcome. Surgical treatment of tricuspid regurgitation has increased in recent years, but in-hospital mortality remains high probably due to the risk profile of the recipients. As a consequence, most of the patients with severe tricuspid regurgitation, especially if isolated, remain untreated. Transcatheter tricuspid valve interventions are rapidly spreading as alternative options to open-heart procedures fulfilling this important unmet need. Although patient selection and timing of intervention are unclear, many devices have been developed in recent years for both repair and replacement of tricuspid valve. Repair tools can be targeted to leaflets or annulus. Replacement devices include heterotopic and orthotropic systems. The aim of this review is to report possible indications and summarize current data about the different devices available for transcatheter tricuspid valve interventions.
