    Radial artery dissection (RAD) occurred in 13.3% of patients undergoing transradial coronary intervention, with 325 lesions identified.

  • 2

    RAD lesions were classified as Type I (flap) or Type II (cavity), with Type I–E1 being the most frequent subtype at 33.8%.

  • 3

    Factors associated with RAD included older age, female sex, longer procedure duration, radial artery spasm, and smaller artery diameter.

  • 4

    In the repeat-OCT cohort, lesions assessed ≥30 days showed complete healing, primarily through intimal hyperplasia or fibrous plaque.

  • 5

    The mean remodeling index was 0.94 ± 0.11, indicating mild negative remodeling in the healing process of RAD lesions.
