Perc. Transvenous Mitral Commissurotomy

From Bay Area Structural Heart Wiki

DRAFT


Anesthesia Imaging Access Pre-Procedure Billing
None Fluoro, TTE, and ICE
possible TEE
Femoral Vein x 2


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 (if using ICE)
  • 8frx10cm Pinnacle (if doing RHC)
  • 8.5 SL1 transseptal

Wires:

Open

  • .035 150J (if needed for RHC)
  • .032 260cm J

TransSeptal Equipment:

Open

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


Catheters:

  • 6F Swan (if recent RHC has not been performed)
  • 8F Accunav (If using ICE))

Misc Supplies:

Open

  • Micropuncture
  • US probe cover
  • 3-port manifold
  • Stopcock for woggle

Have Prepped:

  • Cup with full strength contrast
  • Bowl with 80/20 saline/contrast mixture


Procedure:

  • Dual venous access with micropuncture and ultrasound.
    • 8F standard sheath for Swan insertion if necessary. If no RHC directly with 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
  • Probable LA-gram (10ml Full strength contrast)
  • 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
  • Inoue 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 and slenderizer reinserted
  • Possible gradient measured with SL1 and 6fr PA catheter.
  • Figure 8 stitch around sheath. Sheath removed. Plan for Woggle.
