Perc. Transvenous Mitral Commissurotomy

DRAFT

Device:

• Toray INOUE-Balloon Kit

Size determined using the equation (height in cm/10 +10), but verify with MD because body habitus is also a factor.

Sheaths:

Open

• 9frx25cm Pinnacle
• 8frx10cm Pinnacle
• 8.5 SL1 transseptal

Wires:

Open

• Cordis 150J
  

TransSeptal Equipment:

Open

• Baylis generator from EP
• Large curve C1 Baylis needle
• Baylis cable
• Grounding pad

Catheters:

• 7F Swan (if recent RHC has not been performed)
• 8F Accunav

Misc Supplies:

Open

• Micropuncture

US probe cover

• (2) 3-port manifolds
• Closure
  • 0-Prolene
  • Perclose

Procedure:

• Dual venous access with micropuncture and ultrasound.
  • 8F standard sheath for Swan insertion if necessary. If no RHC, Preclose followed by SL1.
  • 9F 25cm sheath for ICE catheter
• Swan advanced for RHC pressures (if needed)
• ICE advanced
• Transseptal equipment advanced and septostomy performed
• LA pressure measurement
• Balloon Prepped on back table
  • 80/20 saline to contrast concentration
  • Vent port cleared with contrast solution until solution flows from main inflating channel.
  • Balloon sizing verified by filling and measuring with enclosed calipers
  • Slenderizer inserted to elongate balloon
  • MD will shape stylet to match LA anatomy
• Guidewire advanced to LA
• SL1 removed. ICE catheter removed.
• Black dilator advanced and removed
• Balloon advanced
• Verification by TTE for acceptable Mitral valve crossing
• Balloon inflation performed and gradients measured by echo
• Inflation repeated if necessary
• Guidewire reinserted
• Stylet removed, slenderizer advanced. Guidewire reinserted.
