Clinical Challenge in Patients With AF Undergoing PCI
7
Risk of stent thrombosis (ST), stroke and bleeding 1. ST: 1 st month 2. Stroke: steady (CHA 2 DS 2 -VASc score) 3. Bleeding: with the number of antithrombotic CS High in the first 3 months

Lancet 2013
WOEST trial Limitations Small number of patients (n=573) Not adequately powered for MACE < 25% received PCI for ACS 69% received VKAdue to AF 74% with femoral approach Differences in all bleeding driven by minor bleeding PPI not used routinely Dewilde WJM et al. The Lancet 2013.
Even when the duration of full dose TT was 6 weeks, a large percentage of the bleeding has already occurred.

Unanswered questions Which antiplatelet agent shall we stop early: Aspirine or P2Y12 antagonist What is the place of new potent antiplatelet therapy (ticagrelor or prasugrel) in patients with stenting and AF Can we stop the last antiplatelet agent 1 year after PCI in AF patient on OAC Can we apply the same rules to valvural or TAVI patients Montalescot G.
