Summary

Tricuspid regurgitation (TR) is a common disease, and the tricuspid valve (TV) is no longer a "forgotten valve". Open heart surgery for isolated TR is uncommonly performed due to high operative risk (8-10% mortality). However, TR is associated with increased morbidity and mortality. There exists an unmet clinical need for less invasive intervention to treat TR. Transcatheter edge to edge repair (TEER) is a technique that is shown to be safe and effective in TR reduction and is associated with significant symptom improvement. However, a significant portion of TV anatomy are not suitable to be treated with TEER (e.g. coaptation gap \>10mm). A wide variety of technologies has been developed in recent years. Transcatheter tricuspid valve replacement (TTVR) is one of the more promising option for tricuspid regurgitation (TR) patients at high risk for surgery. A previous study reported that transcatheter tricuspid devices, which were employed with the radial force between the device and tricuspid annulus, were radial force-dependent. However, this radial force for valve fixation may cause complications, such as conduction block and right coronary artery impingement. The LuX-Valve (Jenscare Biotechnology) is a radial force-independent orthotopic TTVR device. The feasibility and efficacy of this device have been reported by several studies. However, this valve was implanted through right atrial access, where a small incision of the right chest and right atrium is needed. The LuX-Valve Plus valve replacement system is the second-generation version of the LuX-Valve and can be implanted through the jugular vein. The first-in-human implantation was recently performed. The study aims to assess the feasibility, safety and efficacy outcome of the Lux Valve Plus system in a cohort of otherwise no surgical option patients with severe symptomatic tricuspid regurgitation despite optimal medical therapy.
