    2. Left main location
    3. Located within 2 mm of the origin of the LAD or LCX
    4. Located within an arterial or saphenous vein graft or distal to a diseased (defined as vessel irregularity per angiogram and > 20% stenosed lesion, by visual estimation) arterial or saphenous vein graft
    5. Lesion involving a bifurcation ≥ 2 mm in diameter and ostial lesion > 40% stenosed by visual estimation or side branch requiring predilatation
