Key result

CCTA-guided angiography yields ~73% selective engagement success in anomalous coronary arteries.

n=69

Key Points

The study aims to evaluate catheter engagement success for anomalous coronary arteries identified by coronary computed tomography angiography during invasive procedures.
Performed a retrospective analysis of patients with anomalous coronary arteries evaluated by CCTA and invasive angiography.
Investigated the type of catheters used based on anatomical locations of the arteries.
Included patient demographic data, imaging, and procedural characteristics.
69 patients with anomalous coronary arteries evaluated between January 2019 and October 2024.
Selective engagement of arteries was successful in 73.1% and angiography in 98.6% of patients.
Majority of cases used an average of 2.7 catheters, with contrast volume averaging 98.1 ml and fluoroscopy time at 15.7 minutes.

Type

Observational (n=69)

Multicenter

Structured PICO

Population

69 patients (mean age 67.8 years, 39.1% female) with anomalous aortic origins of a coronary artery demonstrated by CCTA who underwent invasive angiography.

Exposure

Evaluation of AAOCA using coronary computed tomography angiography (CCTA) to guide catheter selection during invasive angiography.

Outcome

Type of catheter utilized for the successful engagement of an AAOCA based on its anatomic location.

Discussion

No takes yet. Share an insight, caveat, or question.

Implication

CCTA may be a useful adjunct for pre-procedural planning of catheter selection prior to invasive angiography in patients with anomalous coronary arteries.

Beerkens et al. (2025) conducted an observational in Anomalous aortic origins of a coronary artery (AAOCA) (n=69). CCTA evaluation of AAOCA ostia was evaluated on Selective engagement success. In patients with anomalous coronary arteries evaluated by CCTA, selective engagement and angiography were successful in 73.1% and 98.6% of cases, respectively, requiring a mean of 2.7 catheters.
