Mitral regurgitation (MR) is the most prevalent valvular heart disease in the U.S., affecting approximately 1.7% of the population. MR prevalence increases with age, rising from 0.5% among 18-44 year olds to 9.3% among those aged 75 years and older [1,2]. There are 4.1 million patients in the US with moderate to severe MR requiring treatment. However, only approximately 30,000 patients in the U.S. undergo surgery for MR each year [3]. The vast majority of patients are not treated today because of the concerns about procedural complexity and patient safety during open-heart surgery. Transcatheter mitral valve repair (TMVRep) or replacement (TMVR) offer less invasive treatment options for MR patients. However, after more than a decade of development, the field of transcatheter mitral valve therapy is still in its infancy. Many of the current TMVRep and TMVR devices have dismal clinical results.


Sutra TMVR is a percutaneous, transcatheter bioprosthetic MV replacement system that bridges the best aspects of TMVR and TMVRep approaches. Sutra TMVR is the only percutaneous system with a crescent-shaped valve to replace the posterior leaflet to effectively restore mitral valve function. Compared with other TMVR devices in development, the Sutra TMVR system features unique advantages:

Sutra TMVR – Unique Crescent-Shaped Valve

  • Replaces ONLY the native posterior leaflet
  • Preserves the (normal motion of) native anterior leaflet
  • Half frame → requires little space in LV → no LVOT obstruction
  • Deploy anchors on the mitral annulus and during beating heart
  • Precise intra-annular valve deployment via tether guidance
  • Small crimp profile for delivery → enables transseptal delivery
