5 No complex etiology : No chord rupture No pseudo prolapsed No severe tethering > 11mm (tethering height ) - unless considered for CB +clip LVEDD<70 mm Consideration for Success Systolic Sphericity index < 0.7 No thin ventricle wall No Severe Right heart failure and or Severe TR

11 Cardioband-procedural steps Imaging modalities used during different procedural steps Access Femoral vein Transseptal puncture Transseptal sheath (TSS) positioning Guide catheter (GC) positioning at the landing zone for the 1st anchor Navigation of the GC/device deployment Size adjustment and evaluation of final result (Annular dimensions/ MR grade) Echo/ Fluoro Echo/ Flouro Echo/ Fluoro Echo/ Fluoro Echo/ Flouro

12 Cardioband- procedural steps 1. Transseptal puncture & introduction of TSS

13 TSP - available area of puncture Not possible TSP area Possible TSP area Optimal Point

14 4 Ch Puncture height: Optimal transseptal puncture site Trans-septal Puncture ME Bicaval view reconstruction Pre-defined by CT Bicaval 16 mm from muscular part SAX 24 mm from Aorta

15 bicaval Transseptal puncture 2D TEE views RA aspect IAS SVC 4-Chambers Short AX Ao Fossa TK IVC

16 Transseptal puncture 3D TEE Anterior of the postero-medial commissure

17 Cardioband- procedural steps 2. System insertion

18 Insertion of the transseptal sheath 3D TEE Avoid wire in the LAA

19 Cardioband- procedural steps 3. Implant deployment

20 The first three anchors Cardioband Implant 1 st 2 nd & 3 rd anchor serve as root foundation for the procedure

21 Navigation scheme Anterior TSS CW rot TSS +\- GC +/- GC - \ + TSS CCW rot. TSS + GC +/- TSS + \ System pull back GC +/- GC + hooking TSS - CLD114 2 Posterior

22 Imaging for deployment of the 1st anchor As anterior as possible! Navigation LAO and 3D Zoom imaging Spool IC tip

23 Imaging for deployment of the 1st anchor SAX at the base Final check 2D/biplane imaging Spool Spool Hinge point Sometimes it s easier to find Distance from aorta? the first / last anchor location from Short Axis at the base. Distance from hinge point? Deployment angle? Proximity to vessels? Spool lateral?

24 Biplane imaging- check for each anchor: Distance to the hinge point Examples Position of the Implant Catheter (IC) tip on the annulus with regard to Distance from hinge point Proximity of vessels Angle of deployment in two orthogonal planes (angle towards annulus and early feed back angle, see figure)

25 Check for each anchor Distance to vessels Examples Position of the Implant Catheter (IC) tip on the annulus with regard to Distance from hinge point Proximity of vessels Angle of deployment in two orthogonal planes (angle towards annulus and early feed back angle, see figure) Distance from hinge point

26 Imaging for Anchor deployment Anchor deployment RAO and 2D/biplane imaging pull test RAO and 2D/biplane imaging Tip of the implant and tissue move in unison Relative movement of GC tip towards IC tip Extrasystolic beats may occur

27 Landing zone and hinge point in 3D Workflow: from AL to PM commissure AL PM P1 P3 P2 Diastole Systole

28 3D TEE views for different regions Examples Surgical view - overview P1 P1 P1 P2 - non surgical view P3 Distance from hinge point

29 Cardioband- procedural steps 4. Implant size adjustment
