Abbott has today announced it has received CE mark approval for its fourth-generation MitraClip transcatheter mitral valve repair system. Known as MitraClip G4, the device is now approved for use in Europe and other regions that recognise CE mark as a non-surgical option for the treatment of mitral regurgitation (MR), or a leaky heart valve. The device is already approved for use in the USA.
The MitraClip G4 system provides physicians in Europe with enhancements to MitraClip’s first-of-its-kind clip-based technology, building upon the device’s delivery system. In addition to offering advanced steering during implantation, the new delivery system offers four clip sizes, including two wider clips, for doctors to have a greater variety of treatment options that can be tailored to a patients’ unique mitral valve anatomy. The newest-generation device also offers independently controlled grippers, if needed, that allow physicians to grasp one or both mitral valve leaflets at a time during the MitraClip procedure.
MR is one of the most common heart conditions, affecting one in 10 adults age 75 and older. Patients with this progressive condition have a mitral valve that does not close completely, allowing blood to flow backward into the left atrium of the heart instead of forwards (out of the heart) and to the rest of the body. While medication can help people manage the symptoms of MR, it does not treat the leaky valve itself. Prior to MitraClip, open-heart surgery was the standard treatment for MR, however, not all patients are eligible or appropriate for open-heart surgery due to the potential risk of complications stemming from comorbidities, advanced age or other issues.
MitraClip is a first-of-its-kind minimally invasive transcatheter mitral valve repair (TMVr) therapy that can be a life-saving treatment option for select patients with primary or secondary MR. The small clip-based device is delivered to the heart through a vein in the leg and clips portions of the leaflets, or flaps, of the mitral valve together to reduce the backflow of blood. Once in place, MitraClip restores the proper functioning of the mitral valve and the heart’s ability to pump oxygenated blood more efficiently.
“Despite being consistently recognised as a problem in patients around the world, MR cannot be treated through the conventional method of open-heart mitral valve surgery in more than half of the people who have this condition,” said Ralph Stephan Von Bardeleben, head of the Heart Valve Center Mainz, Universitätsmedizin Mainz, Germany, who treated the first MitraClip G4 patients in the EU. “The newest MitraClip therapy offers physicians a reliable option when surgical treatment of MR isn’t possible or appropriate, and MitraClip G4’s enhancements allow further customisation of the therapy to tailor treatment to individual patient needs.”
MitraClip is backed by more than 16 years of clinical experience with proven safety, survival and durable clinical outcomes. Data presented at PCR e-Course this year from a real-world clinical study of over 1,000 MitraClip patients showed a high implant success rate (99%) and demonstrated MR reduction to the level of none or trace in patients with either primary MR (to ≤1+ in 87.1%) or secondary MR (to ≤1+ in 90.1%) at 30 days. This recent data confirms MitraClip’s best-in-class MR reduction to date1 and adds to a body of evidence that demonstrates significant impact for patients, including improved clinical outcomes and quality of life.
“An enduring measure of our mission to help people live better lives through better health is our success in advancing new standards of care for the treatment of structural heart diseases,” said Michael Dale, senior vice president of Abbott’s structural heart business. “This CE Mark, along with other recent approvals and advancements for our MitraClip device, underscores the need for MitraClip’s innovative therapy – which has become a preferred choice for the treatment of mitral regurgitation around the world.”
The MitraClip system has been commercially available in the USA since 2013 and in Europe since 2008. Recent regulatory milestones for the device include the first-ever commercial introduction of MitraClip therapy to China and approval in Japan for the fourth generation of MitraClip, both in June of 2020. These milestones are of critical importance for the Asia-Pacific region where many people suffer from MR but may not have had a treatment option available to them. Since its initial approval, more than 100,000 people have been treated with MitraClip in all major regions around the world.
