FDA approves first tricuspid valve replacement system for tricuspid regurgitation
The US Food and Drug Administration has approved Evoque as first transcatheter treatment for tricuspid regurgitation. The new transcatheter treatment Evoque is indicated for severe TR that is symptomatic despite optimal medical therapy and it's use is declared appropriate by a multidisciplinary heart team.
“Edwards has a long history of leading innovation and pioneering new therapies to address the unmet needs of patients with structural heart disease,” said Daveen Chopra, Edwards’ corporate vice president, transcatheter mitral and tricuspid therapies. “We are grateful for the strong collaboration with clinicians all over the world who contributed to the EVOQUE system now being available through FDA’s Breakthrough Pathway to provide a treatment option to the many patients in the US suffering with tricuspid valve disease.”
The EVOQUE system is comprised of a nitinol self-expanding frame, intra-annular sealing skirt and tissue leaflets made from the company’s proven bovine pericardial tissue. The EVOQUE valve will be available in three sizes, all delivered through the same low-profile transfemoral 28F system.
“Patients suffering with tricuspid regurgitation endure life-impairing symptoms and, until today, had no approved transcatheter treatment options,” said Susheel Kodali, MD, director, Structural Heart and Valve Center at Columbia University Irving Medical Center/New York-Presbyterian Hospital and TRISCEND II Study Principal Investigator. “The EVOQUE system is able to replace the native tricuspid valve, virtually eliminating tricuspid regurgitation in a wide range of patients. We see significant improvements in patients’ symptoms and quality-of-life, including not feeling short of breath and being able to care for themselves, which ranked highest on a patient preference survey conducted at baseline with TRISCEND II pivotal trial patients.”
Successful six-month results from the randomized controlled pivotal trial, TRISCEND II, were presented at TCT 2023 and reported favorable safety and effectiveness outcomes, demonstrating superiority to OMT alone and meeting all primary endpoints. Key findings in the trial included significant reduction or elimination of tricuspid regurgitation and significant and sustained quality of life improvement, while demonstrating a favorable balance between risk and benefit.
In addition to the six-month cohort, 318 of the total 392 randomized patients completed a 1-year visit. The results showed favorable trends in the device group compared to the control group in the primary composite endpoints, including all-cause mortality, tricuspid intervention, heart failure hospitalization, KCCQ, NYHA and 6MWD. Edwards expects to present the full cohort of 392 TRISCEND II pivotal trial patients at TCT 2024.
The EVOQUE system received CE Mark approval in October 2023, making it the world’s first transcatheter valve replacement therapy to receive regulatory approval to treat TR.
