Abstract
Background: The prevalence and location of coronary artery disease (CAD) in anomalous aortic origin of a coronary artery (AAOCA) remain poorly documented in adults. We sought to assess the presence of CAD in proximal (or ectopic) and distal (or nonectopic) segments of AAOCA. We hypothesized that the representation of CAD may differ among the different courses of AAOCA.
Methods: The presence of CAD was analyzed on coronary angiography and/or coronary computed tomography angiography in 390 patients (median age 64 years; 73% male) with AAOCA included in the anomalous coronary arteries multicentric registry.
Results: AAOCA mainly involved circumflex artery (54.4%) and right coronary artery (RCA) (31.3%). All circumflex arteries had a retroaortic course; RCA mostly an interarterial course (98.4%). No CAD was found in the proximal segment of interarterial AAOCA, whereas 43.8% of retroaortic AAOCA, 28% of prepulmonic AAOCA and 20.8% subpulmonic AAOCA had CAD in their proximal segments ( P < 0.001). CAD was more prevalent in proximal than in distal segments of retroaortic AAOCA (OR: 3.1, 95% CI: 1.8-5.4, P < 0.001). On multivariate analysis, a retroaortic course was associated with an increased prevalence of CAD in the proximal segment (adjusted OR 3.4, 95% CI: 1.3-10.7, P = 0.022).
Conclusion: Increased prevalence of CAD was found in the proximal segment of retroaortic AAOCA compared to the proximal segments of other AAOCA, whereas no CAD was observed in the proximal segment of interarterial AAOCA. The mechanisms underlying these differences are not yet clearly identified.
期刊介绍：
Coronary Artery Disease welcomes reports of original research with a clinical emphasis, including observational studies, clinical trials, translational research, novel imaging, pharmacology and interventional approaches as well as advances in laboratory research that contribute to the understanding of coronary artery disease. Each issue of Coronary Artery Disease is divided into four areas of focus: Original Research articles, Review in Depth articles by leading experts in the field, Editorials and Images in Coronary Artery Disease. The Editorials will comment on selected original research published in each issue of Coronary Artery Disease, as well as highlight controversies in coronary artery disease understanding and management.
Submitted artcles undergo a preliminary review by the editor. Some articles may be returned to authors without further consideration. Those being considered for publication will undergo further assessment and peer-review by the editors and those invited to do so from a reviewer pool.
