DFM Mitral Design Advantages

Advantages

  • Conformable device to accommodate complex

mitral anatomy

  • Flexible delivery system for transseptal or

trans-aortic access

  • Lowest PVL rates (even more critical in mitral

position)

  • Adjustable positioning
  • Allows assessment of results before

implantation (even more critical in dynamic mitral

annulus)

  • Proven design that does not rely solely on

radial force for anchoring

  • Atraumatic frame to preserve native chordae
  • Retrievable
  • Challenges:
  • Limited length in TA anatomy for Position

Wire management and retrieval

  • Transapical approach only (with current

configuration)

  • No “tissue anchoring” fixation
  • Limited Diameter
  • Maintain sufficient LVOT clearance
  • Conformable shape
  • Sealing and Anchoring

Rings

  • Atraumatic frame
  • Flexible Delivery

DFM and the Mitral Space

Universal Platform:

Addressing Mitral Valve Disease

Unique potential design advantages:

  • Double-ring valve for optimal sealing
  • Valve design accomodates D-Shape
  • Upsizing to mitral diameters feasible
  • Metal-free design/profile facilitates trans-septal delivery
  • Repositionable/retrievable (LVOT Obstruction, Sizing)

Current Challenges of TMVR

  • Paravalvular leak
  • Anchoring
  • LVOT obstruction
  • Erosion
  • Thrombus

– Atrial and ventricular

  • Stent fracture
  • Unproven valve/leaflet durability
  • Lack of repositionability and retrievability

Anticipated Mitral Valve Design Benefits

  • Clinically proven conformable design

– Precise placement – Conformable annular seal – Excellent PVL performance – Repositionable & retrievable

  • Low ventricular projection

– Atrialized design – Minimal stasis | LVOT obstruction

  • Trigone anchors

– Allow normal native leaflet movement

  • Non metallic construction

– Facilitates future trans-septal approach – No stent fracture risk – Minimal perforation risk
