continuation of ASA
minimum interruption of ticagrelor and clopidogrel for 48-72 hours before CABG ideal interruption period of 5 days before elective CABG

21
Q

Patients with AF without High-Risk Features who Undergo Elective PCI: Age < 65 and CHADS2 = 0

A

ASA + Clopidogrel
Duration: at least 1 month for BMS and at
least 3 months for DES (and up to 12 months)

22
Q

Patients with AF without High-Risk Features who Undergo Elective PCI: Age ≥ 65 or CHADS2 ≥ 1

A

OAC2 + Clopidogrel
Duration: at least 1 month for BMS and at
least 3 months for DES (and up to 12 months)

23
Q

Patients with AF who Undergo PCI for ACS or High-Risk Elective PCI: Age < 65 and CHADS2 = 0

A

ASA + P2Y12 inhibitor2
(ticagrelor, prasugrel preferred
over clopidogrel for ACS)
Duration after PCI: Up to 12 months

24
Q

Patients with AF who Undergo PCI for ACS or High-Risk Elective PCI: Age ≥ 65 or CHADS2 ≥ 1

A

Reduced OAC3 + ASA + clopidogrel
ASA: stop 1 day post PCI or any time up to 6 months4
Followed by: clopidogrel + OAC
Duration after PCI: Up to 12 months

25
Q

Patients with Venous Thromboembolism OR established left ventricular thrombus Undergoing PCI for an ACS or non-ACS indication

A

initial regimen of ASA 81 mg daily plus clopidogrel 75 mg daily plus either parenteral OR oral anticoagulation (in accordance with
DVT/PE recommendations).

ASA may be discontinued as early as the day following PCI or it can be continued up to 6 months of treatment, depending on the risk of recurrent ischemic events versus major bleeding.

Following ASA discontinuation, we suggest that OAC plus clopidogrel
75 mg daily be continued for up to 12 months after the initial PCI

26
Q

In patients undergoing PCI for an ACS indication who are high-risk of developing LV thrombus

A

DAPT with ASA 81 mg daily plus either ticagrelor 90 mg twice daily or prasugrel 10 mg once daily
for up to 1 year

27
Q

In patients with a mechanical valve replacement who undergo PCI for an ACS or non-ACS indication:

A

ASA 81 mg daily plus clopidogrel 75 mg daily plus a vitamin
K antagonist (VKA) (triple therapy).

ASA may be discontinued as early as the day after PCI or it can be continued up to 6 months of treatment,

28
Q

In patients with a surgical bioprosthetic valve replacement (implanted < 6 months) who undergo PCI for an ACS or non-ACS indication:

A

DAPT with ASA 81 mg daily and clopidogrel
75 mg daily for at least 6 months (and up to 12 months)

29
Q

In patients with a transcatheter aortic valve replacement (TAVR) (implanted < 6 months) who undergo PCI for an ACS or non-ACS indication:

A

DAPT with ASA 81 mg daily and
clopidogrel 75 mg daily for 3-6 months
