To determine the incidence, classification, healing patterns, vascular remodeling, and factors associated with radial artery dissection (RAD) identified by optical coherence tomography (OCT).
Key Findings:
RAD occurred in 266/1,995 patients (13.3%), with 325 RAD lesions identified.
The most frequent baseline subtype was Type I–E1 (33.8%).
Factors associated with RAD included older age, female sex, longer procedure duration, radial artery spasm, and smaller radial artery diameter.
In the repeat-OCT cohort, lesions reassessed ≥30 days showed complete healing, predominantly through intimal hyperplasia (60%) or fibrous plaque (40%).
The mean remodeling index was 0.94 ± 0.11.
Interpretation:
Remove unsupported conclusions and rephrase to reflect only findings.
Limitations:
Single-center study may limit generalizability.
Retrospective design may introduce selection bias.
Conclusion:
Revise to eliminate unsupported implications and focus on findings.
