Is this trial a fit for you?

Likely a good fit

Adults (≥18 years) with severe or greater TR who are suitable candidates for TTVR after Heart Team assessment.

Probably not a fit

Patients with urgent surgery needs, poor LV function (EF <25%), life expectancy under 1 year, or anatomical contraindications may not benefit.

What this trial studies

This is a prospective, global, multi-center randomized study comparing the TRiCares Topaz TTVR system to the Edwards EVOQUE TTVR system in patients with severe or greater tricuspid regurgitation. Participants are assigned 1:1 to receive either device, and the trial focuses on safety and effectiveness outcomes. Eligible patients are adults with symptomatic TR despite optimal medical therapy and deemed suitable for TTVR by their Heart Team. Key exclusion criteria include existing tricuspid devices, anatomical contraindications, need for urgent surgery, LV ejection fraction <25%, or limited life expectancy (<1 year). The study is led by TRiCares with sites including Piedmont Heart Institute in Atlanta.

Why it matters

Potential benefit: If successful, the trial could validate a safe and effective alternative for TTVR in patients with severe TR, potentially expanding treatment options.

How similar studies have gone: Prior work in transcatheter valve therapies has shown safety and effectiveness signals for similar devices, but this specific head-to-head comparison is novel.
