2. If surgery is indicated:Which stent is appropriate in PCI?- Bare metal stent (BMS)- Drug-eluting stent (DES)

If a patient will receive planned non-cardiac surgery but who needs PCI at first:

Delay the surgery

Yes No

As usual PCI treatment PTCA without stent implantation or Bare metal stent implantation

2. If surgery is indicated:Which stent is appropriate in PCI?- Bare metal stent (BMS)- Drug-eluting stent (DES)

3. If a drug-eluting stent was chosen:(a) Which DES is best?(b) How long should the dual anti-platelet therapy (Aspirin+ Clopidogrel) be used?

SENSOutcome of Non-cardiac Surgical Procedure andBrief Interruption of DAPT within 12 Months Following Endeavor Implantation

SENS Trial at ACC09

SENS StudyAlthough current guidelines recommend DAPT for 12 months, the SENS study concluded that in the patients evaluated, Endeavor “appears to be safe and feasible in patients undergoing non-cardiac surgical procedure” after 3 months following stentimplantation.

Discussion 5:

• Is it feasible and safe to use 5 Fr transradial guiding catheter in PCI?

• If the diagonal branch was jailed and complex procedure (IVUS, kissing balloon technique) should be done, 5 Fr may be not the best choice
