Tricuspid Regurgitation Functional

The purpose of this clinical trial is as follows. To assess the safety of the investigational medical device "Pivot Bridge" in participants aged 18 years or older with massive or greater functinal tricuspid regurgitation (TR) who have received medical therapy (diuretics/pharmacological treatment) for at least one month. To evaluate clinical outcomes related to improvement of tricuspid regurgitation symptoms following implantation of the "Pivot Bridge" device, including procedure success and clinical success. This study is designed as a self-controlled case series without a separate control group. The participant's non-exposure period to the investigational medical device, consisting of prior medical therapy (Medical Treatment, MT), is defined as the control period. The study compares (1) a period of fixed-dose medical therapy maintained for up to one week prior to application of the investigational medical device, and (2) a period during which the investigational medical device is temporarily implanted (within 1 week) in conjunction with medical therapy (Pivot Bridge, PB). To quantitatively evaluate the efficacy of the investigational medical device in inducing improvement of tricuspid regurgitation, the following are assessed: 1. improvement in regurgitation severity from baseline to Day 4-7 during fixed-dose medical therapy (ΔMT), and 2. improvement from pre-application to the time of device removal following additional application of the Pivot Bridge (ΔPB).

Purpose of this clinical study is to demonstrate the safety and efficacy of MIA-T system in improving clinical outcomes in symptomatic patients with severe tricuspid regurgitation (TR grade ≥3) despite optimal medical therapy, who have been determined by the site's local heart team to be at intermediate or greater estimated risk for mortality and morbidity with tricuspid valve surgery.

The goal of this clinical trial is to evaluate the safety and technical success of the Tangent Tricuspid Annular Therapy System in patients with severe, symptomatic functional tricuspid regurgitation.

Early Feasibility Study to evaluate the safety and performance of the Innoventric Trillium™ Stent Graft in the treatment of severe or greater tricuspid regurgitation (TR).

An early feasibility study to evaluate the safety and performance of 1) the transcatheter delivery and implantation of the Cardiac Implants (CI) annuloplasty ring and 2) the adjustment of the ring approximately 90 days following implantation in patients suffering from ≥ moderate functional tricuspid regurgitation (FTR).
