Q
  1. wp of SVG are occlused at 1 year
  2. IMA at 1 yr
  3. RF for graft occlusion
  4. SVG metanalysis dapt
  5. Naitive vs. SVG PCI?
  6. mace events compared to normal
  7. No reflow with svg pci
  8. post dil w/ svg
A
  1. 19%, 26% in another study.
  2. 5%
  3. pt factors - younger age pt, EF <30%, HLD, No ASA, enoscopic harves. smoking

Graft - older grft, smaller target diameter, large graft, smaller runoff, distal anastomasolis < 2.0

  1. metaanlaysus shoed DAPT higher patency of SVG and loer mort at 1 year compared to asa alone. but higher bleeding and no diferince in bleeding.
  2. favor naitive mantra
  3. MACE rate compared to normal… 2x
  4. 5-30%
  5. try to avoid

Q
  1. no reflow w/ svg intervention death rate
  2. SVG PCI IIb/IIIA
  3. what else doesnt help
  4. doages for medicined for no reflow -
  5. push verapamil need to think about what?
A
  1. 5-15%–> shoc and heart block (10 x infold) “wake up and smell the flowers”…
  2. placebo is better.
  3. NTG, CABG, lytics, IIBIIIA dont dilate
  4. doages for medicined for no reflo adenosine 10-60 Uc IC, nitroprusside 100, nicard 100verap 100 (everything 100!, except adenosine a little less) everyting is microgram too.

Q

embolic protection

  1. SAFER trial
  2. SAFER predictors of MACE
  3. “david cox” great saying about distal protection.

4. problem

5. fire studyy

6. GL rec for SVG

A
  1. Baloon distal - non q ave, mace was less,
  2. No EPD yse, SVG degenration score, plaque volume
  3. when do you not wear your seatbelt. \
  4. need a 20 mm landing zone. filter can clog. can get stuck
  5. filter vs. gaurdwire same safter

Q

STAR and ministar

ADR length requirement

Best channes in order for retrograde approach

A

basiclally knucl then re-enter, minstar is just to go sub I in the CTO segment.

need 20 mm at least and no major branches

Q

3 major RCTS for CTO

A

Decision CTO - Park jorea, no difference in mort, too much cross over and many did not achieve - changed enpoint and sample size, negative SAQ

EUROCTO - 2:1 randomization, omt 2 anginal medications. improved QOL (spetus)

impactor CTO - omt v. pci ischemia burden sig reduced and phyica; limitation also improved

wire componts

  1. core
  2. tip style
  3. coating
  4. tip stiffness give some stiff wires
A
  1. determines stiffenss of wire and taper and length of taper is impt for steep curves

2, core to tip transition may improve torque compared to shaping ribbon.

  1. hydrophilic coating

A

murrary and finets law

2/3 sum added together will be proxima.

distal most cell.

18

Metformin hen to dc

A

at time of procedure if normal renal function and 48 hours if not.

22

duration of dual antiplatet therapy

A

12 vs. 30 mo therpay after mi –> no difference in mort trend to higher at 1 year. 1% of increased risk of major bleeding. this i why dapt didnt change anything.
