Analysis of local dissections of the treated vessel segment post-procedural and at 6-month invasive f/u with angiography and OCT (N = 45 lesions with sufficient OCT imaging quality and matching angiography)
| Dissection assessment by OCT at f/u | Angiography after PCI | Angiography at f/u | ||||
|---|---|---|---|---|---|---|
| No dissection (N = 19) | Type A dissection (N = 19) | Type B dissection (N = 7) | All dissections (N = 26) | No dissection (N = 41) | Type A dissection (N = 4) | |
| Dissections present at f/u | 8 (42 %) | 10 (53 %) | 2 (29 %) | 12 (46 %) | 18 (42 %) | 2 (50 %) |
