ACC/AATS/AHA/ASE/ASNC/SCAI/SCCT/ STS 2017 Appropriate Use Criteria for Coronary Revascularization in Patients With Stable Ischemic Heart Disease

Revascularization to Improve Survival Compared With Medical Therapy (DO NOT EDIT)

Anatomic Setting COR LOE
UPLM or complex CAD
CABG and PCI I—Heart Team approach recommended C
CABG and PCI IIa—Calculation of STS and SYNTAX scores B
UPLM
CABG I B
PCI IIa - For SIHD when both of the following are present:

1) Anatomic conditions associated with a low risk of PCI procedural complications and a high likelihood of good long-term outcome (e.g., a low SYNTAX score of ≤ 22, ostial or trunk left main CAD) 2) Clinical characteristics that predict a significantly increased risk of adverse surgical outcomes (e.g., STS-predicted risk of operative mortality ≥ 5%)

B
PCI IIa—For UA/NSTEMI if not a CABG candidate B
PCI IIa—For STEMI when distal coronary flow is TIMI flow grade <3 and PCI can be performed more rapidly and safely than CABG C
PCI IIb—For SIHD when both of the following are present:1) Anatomic conditions associated with a low to intermediate risk of PCI procedural complications and an intermediate to high likelihood of good long-term outcome (e.g., low-intermediate SYNTAX score of <33, bifurcation left main CAD) 2) Clinical characteristics that predict an increased risk of adverse surgical outcomes (e.g., moderate—severe COPD, disability from prior stroke, or prior cardiac surgery; STS-predicted operative mortality >2%) B
PCI III: Harm—For SIHD in patients (versus performing CABG) with unfavorable anatomy for PCI and who are good candidates for CABG B
3-vessel disease with or without proximal LAD artery disease
CABG I B
