Effect of Crack Patterns in Calcified Plaque on Lumen Area after Stenting for a Severe Calcified Coronary Artery (from the Optical Frequency Domain Imaging-Guided Percutaneous Coronary Artery Intervention for Calcified Lesion Registry)

Figure 1

Crack formation pattern of calcified plaque. (a) Type 0, no cracks or injury in the vessel. (b, c) Type 1, with crack in calcified plaque (yellow arrowhead) or intima injury (red arrowhead) without medial dissection between calcified plaque and vessel wall. (d) Type 2, with crack in calcified plaque with medial dissection between calcified plaque and vessel wall (blue arrowhead).
