|Indication||Appropriate Use Score (1–9)|
|62.||• Two-vessel CAD with proximal LAD stenosis||A (7)||A (8)|
|63.||• Three-vessel CAD with low CAD burden (i.e., 3 focal stenoses, low SYNTAX score)||A (7)||A (9)|
|64.||• Three-vessel CAD with intermediate to high CAD burden (i.e., multiple diffuse lesions, presence of CTO, or high SYNTAX score)||U (4)||A (9)|
|65.||• Isolated left main stenosis||U (6)||A (9)|
|66.||• Left main stenosis and additional CAD with low CAD burden (i.e., 1- to 2-vessel additional involvement, low SYNTAX score)||U (5)||A (9)|
|67.||• Left main stenosis and additional CAD with intermediate to high CAD burden (i.e., 3-vessel involvement, presence of CTO, or high SYNTAX score)||I (3)||A (9)|
|68.||U (6)||A (7)|
|69.||A (8)||U (6)|
New and updated indications are shaded blue.
A = appropriate; CABG = coronary artery bypass graft; CAD = coronary artery disease; CCS = Canadian Cardiovascular Society; CTO = chronic total occlusion; I = inappropriate; LAD = left anterior descending coronary artery; LIMA = left internal mammary artery; LVEF = left ventricular ejection fraction; PCI = percutaneous coronary intervention; SYNTAX = Synergy Between PCI With TAXUS and Cardiac Surgery; U = uncertain.
↵⁎ The 2009 appropriate use criteria (1) separated out diabetes and normal or depressed LVEF for the indications in this table, but they were combined for the focused update because these clinical variables did not affect the ratings.
