Retrospective cohort study reveals reduced procedural success and higher radiation exposure in patients with anomalous coronary arteries, highlighting need for optimized protocols.

Key Points

To evaluate the impact of anomalous aortic origin of a coronary artery on coronary angiography success rates, procedural quality, radiation exposure, and contrast volume.
Single-center retrospective matched cohort study conducted from 2011 to 2022.
Included 96 patients with confirmed anomalous aortic origin of a coronary artery (AAOCA+) matched with 96 controls without the anomaly (AAOCA-).
Assessed selective catheterization success, injection quality, fluoroscopy duration, radiation dose, and contrast volume using conditional logistic regression and generalized estimating equations.
Selective catheterization was achieved significantly less often in the AAOCA+ group compared to the AAOCA- group (28.1% vs. 90.6%; OR: 24.1, 95% CI: 10.3–62.6, p < 0.0001).
Injection quality was substantially lower in AAOCA+ patients compared to controls (61.5% vs. 100%, p < 0.0001).
Procedures in the AAOCA+ group required longer fluoroscopy times (11.4 ± 0.8 vs. 5.9 ± 0.8 min, p < 0.0001), higher radiation doses (310.8 ± 35.8 vs. 189.9 ± 36.4 mGy, p = 0.02), and increased iodine contrast volume (99.5 ± 6.7 vs. 61.2 ± 7.6 mL, p = 0.0001).
