new technologies for Mitral regurgitation

  1. 1. Cosa possiamo fare, nella insufficienza mitralica, oltre la MitraClip. Francesco Maisano MD, FESC Ospedale San RaffaeleDipartimentoCardiotoracovascolare
  2. 2. MitraClip in the clinicalpractice Opportunity Challenges– Largeunmetneed – Lackofevidence, parti– Reportedclinical cularlyfor FMR benefit in – Limitedclinicalexperi selectedpatients ence, concentrated in high volume centers – Limitedapplicability
  3. 3. MitraClip anatomical patient selection considerationsRecommended criteria1• Moderate to severe MR (Grade 3 or more out of 4 grades)• Pathology in A2-P2 area• Coaptation length > 2 mm (depending on leaflet mobility)• Coaptation depth < 11 mm• Flail gap < 10 mm• Flail width < 15 mm• Mitral valve orifice area > 4cm2 (depending on leaflet mobility)• Mobile leaflet length > 1 cm 1. The current patient considerations are based on EVEREST II and commercial European experience to date. The MitraClip Patient Selection Coniderations document has been endorsed by Expert Opinion (Crossroads institute).
  4. 4. Anatomic MeasurementsP=0.05 P=0.1 San Raffaele Preliminary data
  5. 5. Tenting area and QRS duration p=0.002 P=0.01 San Raffaele Preliminary data
  6. 6. Jet extension (%) p=0.01Jet extension/IC diameter
  7. 7. What to do in patients beyond MitraClip feasibility• Surgery• Synergistic approaches• New technologies – Annuloplasty – Neochordae implantation – Mitral valve replacement
  8. 8. The Mitraclip is applicable only in selected patients Surgeons use many different techniques to individualize treatment2008-Hugo Vanermen

  14. 14. Transcatheter annuloplasty Coronary sinus remodeling SL dimensions cinching RF/Ultrasound remodeling External compression Direct annuloplasty

Coronary sinus devices MONARC Two-anchor design EVOLUTION (Edwards with chronic trial Lifesciences reshaping (6weeks) (69 pts LLC) by a foreshortening enrolled) bridge CARILLON Acute reshaping AMADEUS trial (Cardiac device acting in (43 pts Dimensions P2P3, repositionable, enrolled ) Inc) retrievable PTMA Tri-lumen catheter, PTOLEMY (Viacor Inc) reshapable, (24 pts possibility of enrolled) multiple long term adjustment

  17. 17. Valtech Cardio - CARDIOBAND• A surgical ring implanted percutaneously
  18. 18. Transcatheter MVR• Larger device• Anchoring• Asymmetric anatomy• Interaction with the aortic valve and LVOT• PVL more problematic
