Tricuspid regurgitation (TR) is one of the most prevalent types of valvular heart disease linked to poor prognosis in patients with heart failure and is usually ignored. TR has received considerable attention due to the progressive advancements in transcatheter therapies in recent years. With relatively solid data and rapid technological advancements, tricuspid transcatheter edge-to-edge repair (T-TEER) is the most frequently employed in a series of tricuspid transcatheter interventional treatments for TR. However, the efficacy and technical benefits of T-TEER are limited because of the unique anatomical characteristics and pathological mechanisms of the tricuspid valve. The aim of this review is to summarize reported data on current status of T-TEER and to provide an expert opinion regarding the challenges it is now experiencing and future development direction and approach. T-TEER is a significant treatment for TR, but its effectiveness and technical promotion are limited due to the tricuspid valve unique anatomical characteristics and pathological mechanisms. The selection criteria for suitable patients, the choice of when to intervene, device innovation, the advancement of ultrasound technology, and the volume of evidence in evidence-based medicine all indicate that the disorder of TR will eventually be better treated and understood.
