Insights
Coronary artery anomalies are rare congenital heart conditions that can disrupt blood flow. This review aids clinicians in recognizing and managing these anomalies, improving patient outcomes.
Area of Science:
- Cardiovascular Medicine
- Congenital Heart Disease
- Radiology
Background:
- Coronary artery anomalies (CAAs) are congenital defects affecting coronary arteries, potentially causing myocardial ischemia.
- Historically diagnosed postmortem, increased imaging use now detects more CAAs in adults.
- CAAs pose a significant cardiovascular health risk due to disrupted blood flow and adverse events.
Purpose of the Study:
- To review current knowledge on CAA classification, mechanisms, and clinical impact.
- To focus on prevalent CAA variants with significant clinical implications.
- To provide a framework for clinical recognition and management of CAAs.
Main Methods:
- Literature synthesis of current knowledge on coronary artery anomalies.
- Focus on prevalent variants and their clinical impact.
- Discussion of medical and surgical management strategies and screening recommendations.
Main Results:
- CAAs are diverse congenital abnormalities with varying clinical significance.
- Prevalent variants with significant impact are highlighted.
- Management strategies and screening recommendations are discussed.
Conclusions:
- A comprehensive framework is provided for recognizing and managing CAAs.
- Stratification by anatomical location aids clinical decision-making.
- Enhanced understanding and management can improve outcomes for individuals with CAAs.
Abstract:
Coronary artery anomalies encompass a spectrum of congenital abnormalities affecting the origin, course, or termination of the major epicardial coronary arteries. Despite their rarity, coronary artery anomalies represent a significant burden on cardiovascular health due to their potential to disrupt myocardial blood flow and precipitate adverse cardiac events. While historically diagnosed postmortem, the widespread availability of imaging modalities has led to an increased recognition of coronary artery anomalies, particularly in adults. This review synthesizes current knowledge on the classification, mechanisms, and clinical implications of coronary anomalies, focusing on prevalent variants with significant clinical impact. We discuss strategies for medical and surgical management, as well as contemporary screening recommendations, acknowledging the evolving understanding of these anomalies. Given the breadth of possible variants and the limited data on some presentations, this review provides a framework to aid clinicians in the recognition and management of coronary anomalies, with a particular emphasis on their stratification by anatomical location. By consolidating existing knowledge and highlighting areas of uncertainty, this review aims to enhance clinical decision-making and improve outcomes for individuals with coronary anomalies.

Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...
Coronary Circulation
Coronary circulation begins at the base of the aorta, where two main arteries arise—the left and right coronary arteries. These arteries encircle the heart in the coronary sulcus and supply the...
