About CathHELIX®

CathHELIX® is a revolutionary catheter-based mitral valve repair device poised to transform the treatment of mitral regurgitation.

CathHELIX® is an investigational device. It has the potential to be the first transcatheter mitral valve repair device that:

  • Is significantly less invasive and involves considerably lower risks than surgical mitral repair; the current gold standard procedure
  • Retains the efficacy of surgical repair
  • Reduces the mitral annulus geometry like in surgery
  • Leaves future treatment options open
  • Is a straightforward and safe procedure designed for routine use by interventional cardiologists.

CathHELIX® is currently in late stage pre-clinical studies.

The CathHELIX® procedure

4 straightforward steps to mitral valve repair

1. Temporary downsizing through coronary sinus

2. Delivery catheters inserted

3. Ring delivery and self-fixation

4. Contractor and delivery catheters removed


About our proprietary helix ring technology, pre-clinical and clinical research.

Patented helix ring technology

HVR Cardio’s patented helix ring technology can be applied to interventional cardiology as well as to cardiac surgery.


HVR Cardio’s innovative helix ring technology is designed to mimic mitral valve geometry. The helix ring is rotated from posterior commissura (the area where the leaflets come together in the mitral annulus) into its intended position. The rotation ensures that the implant is correctly positioned, having one of the helix loops above and the other one below the mitral annulus. This results in faster, easier and more reliable placement of the ring and restoration of the geometry of the mitral annulus.

About MAR®

MAR®, HVR Cardio Annuloplasty Ring, is a new type helix based surgical mitral valve repair device for fast and easy implantation on treatment of mitral valve regurgitation. It may improve the reverse remodelling of the enlarged left ventricle compared to conventional annuloplasty rings.

MAR is designed to provide Consistent results due to “anatomical guiding”. Leaves future catheter options open.
