Table 1
Angiographic classification of coronary artery lesions by ACC/AHA [
8].
| Type A | Type B | Type C |
| Discrete (length < 10 mm) | Tubular (length 10–20 mm) | Diffuse (length > 20 mm ) |
| Concentric | Eccentric | — |
| Readily accessible | Moderate tortuosity of proximal segment | Excessive tortuosity of proximal segment. |
| Nonangulated segment (<45 degrees) | Moderate angulation (45–90 degrees) | Extremely angulated (>90 degrees) |
| Smooth contour | Irregular contour | — |
| Little or no calcification | Moderate or heavy calcification | Degenerated vein grafts with friable lesions |
| Absence of thrombosis | Some thrombosis present | Total occlusion |
| No ostial or major side branch involvement | Ostial or bifurcation lesions (requiring double guidewires) | Inability to protect major side branch |
| Less than totally occlusive | Total occlusions < 3 months old | Total occlusions > 3 months old/bridging collaterals |
