Neovasc Tiara

Tiara Treats Mitral Regurgitaion Condition

Tiara is a novel transcatheter device designed to treat mitral regurgitation (MR), a condition that is often severe and can lead to heart failure and death.

Neovasc is developing the Tiara for the treatment of severe MR, a condition that affects approximately four million patients in the U.S. alone. Currently, conventional surgical treatments are only appropriate for about 20% of these patients, leaving the majority of patients untreated.

The Tiara device is delivered through the apex of the heart to replace the mitral valve while preserving the integrity of the surrounding structures of the heart.

Tiara has been designed specifically to address each of the challenges listed below and meet the need for transcatheter replacement of the mitral valve, rather than being adapted from an aortic valve. Tiara implantation is achieved through a transapical approach and does not require any hemodynamic support.

Challenges to treatment of the mitral valve include:

  • Complex geometry of the mitral apparatus
  • Changes of the mitral apparatus throughout the cardiac cycle
  • Maintaining continuity with the sub valvular structures
  • Native D shape of the mitral valve
  • Proximity to the aortic valve and potential for Left Ventricular Outflow Tract (LVOT) obstruction
  • Large size of the mitral valve – larger crossing profile
  • High closing pressures
  • Left ventricular remodelling
