transcatheter mitral valve replacement #TMVR for failed valve & ⬆️ #STS risk
#VHD 2017 update reoperation➡️ reintervention bit.ly/2P9bX4G
🎈expandable SAPIEN S3 only @FDA bioprosthesis for implant
After 🇨🇦 initial experience with #transapical 2009
sick patients with ⬇️ EF #transeptal preserves EF better avoids apical purse string suture
Currently #TMVR registry
>50 % are transeptal & in house mortality 7%
mean gradient,#PHT,#DVI, for
#EOA use continuity not #PHT
if Significant #MR,#valve #area #underestimated by the #continuity
👀 valve leaflet mobility
R/O obstructing #thrombus/#vegetation-contraindications for #TMVR
structural deterioration or #thrombus➡️typically located on the #ventricular side of #mitral #prosthesis & has soft echotexture 🆚 pannus or structural failure usually brighter echotexture,
c/w fibrous tissue deposition (pannus) or calcification
⬆️Temporal & spatial resolution #2D easy orientation (3D of septum fewer points of reference)
AP sup infer orientation precise selection of septal puncture site catheter tip could be outside the 3D imaging vol
#prosthetic MV is crossed initially with #guide catheter & a stiff delivery wire is 🔁
prosthesis position (how much in LV 🆚 LA) by fluoro
delivery 🎈is positioned across the bioprosthesis under fluro
new valve is then deployed by inflating delivery🎈
(1) Is the valve deployed in stable position? positioned well inside the old valve sewing ring?
(2) Is valve function normal?
(3) Are there any complications?
(4) stability, degree & symmetry of cusp motion?
