Transcatheter Mitral Valve Replacement for Mitral Valve Regurgitation
(TIARA-I Trial)
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial tests a new method to replace a faulty mitral valve without open-heart surgery. It evaluates the safety and effectiveness of the Neovasc Tiara Mitral Valve System, a transcatheter mitral valve replacement, for individuals with severe mitral valve regurgitation. This condition occurs when the heart’s mitral valve doesn’t close tightly, causing blood to flow backward. The trial seeks participants with severe symptoms, such as shortness of breath or fatigue, who are at high risk for traditional surgery. Participants should have heart failure symptoms that significantly affect their daily activities. This study suits those whose condition makes them unsuitable for regular heart surgery. As an unphased trial, it offers a unique opportunity for patients to access innovative treatment options that may significantly improve their quality of life.
Do I need to stop my current medications for the trial?
The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial team or your doctor.
What prior data suggests that the Neovasc Tiara Mitral Valve System is safe for mitral valve regurgitation?
Research has shown that the Neovasc Tiara Mitral Valve System holds promise for safety. Studies have found that the valve implantation procedure is straightforward, consistently performed, and safe. No reports of mechanical problems, such as frame breaks or blood clots, have occurred during its use in clinical settings.
Patients have demonstrated excellent heart function post-procedure, with no major issues before hospital discharge. These findings suggest that the treatment is generally well-tolerated, though further information may be needed to fully understand its long-term safety.
Overall, the initial results are encouraging for those considering participation in trials with the Neovasc Tiara Mitral Valve System.12345Why are researchers excited about this trial?
Unlike the standard surgical options for mitral valve regurgitation, like open-heart surgery for valve repair or replacement, the Neovasc Tiara™ Mitral Valve System offers a minimally invasive alternative. This treatment is unique because it uses a transcatheter approach to replace the mitral valve, which means it can be delivered to the heart through a small incision, reducing the need for more invasive surgery. Researchers are particularly excited about its transapical delivery system, which allows for precise placement of the valve, potentially leading to better outcomes and quicker recovery times for patients. This innovation could be a game-changer, especially for patients who are high-risk surgical candidates.
What evidence suggests that the Neovasc Tiara Mitral Valve System is effective for mitral valve regurgitation?
Research has shown that the Neovasc Tiara Mitral Valve System holds promise for treating mitral valve regurgitation, a condition where the heart's mitral valve fails to close properly, causing blood to leak backward. In early studies, doctors successfully implanted the valve in 96% of patients, with no deaths during the procedure. One study found that after one year, 86% of patients remained alive. In most cases, the valve stayed in place and effectively stopped the backward flow of blood. These results suggest that the Tiara valve could be a good treatment option for people with this heart condition.23467

Are You a Good Fit for This Trial?
This trial is for individuals with severe symptomatic mitral valve regurgitation who are at high risk for open heart surgery and have advanced heart failure (NYHA Class III or IV). It's not suitable for those who can undergo regular valve surgery, are extremely frail, listed for a cardiac transplant, or have unsuitable cardiac anatomy.Inclusion Criteria
