Medial Degeneration in Patients With and Without Aortic Root Involvementa
| Medial degeneration | Mild | Moderate | Severe |
|---|---|---|---|
| Root involvement (n = 23) | |||
| Aortic dissection, No. | 0 | 0 | 2 |
| Aneurysm, no dissection, No. | 1 | 9 | 11 |
| Total, No. (%) | 1 (4) | 9 (39) | 13 (57) |
| No root involvement (n = 63) | |||
| Aortic dissection, No. | 5 | 14 | 13 |
| Aneurysm, no dissection, No. | 11 | 10 | 10 |
| Total, No. (%) | 16 (25) | 24 (38) | 23 (37) |

The difference in the distribution of medial degeneration scores between patients with and without aortic root involvement did not reach statistical significance (P = .09). P < .05 was considered statistically significant.
