This editorial emphasizes the superiority of CCTA over invasive coronary angiography for accurately identifying and characterizing congenital coronary artery anomalies, which is crucial for preventing sudden cardiac death and surgical complications.
The embryonic heart undergoes a remarkable transformation during the first trimester of pregnancy.Initially, the myocardium is thin, and immature vascular plexus develop on its outer surface.This plexus fueled by migrating progenitor cells from both endocardium and sinus venosus, eventually connect with the aorta, receiving blood flow and transforming into primitive coronary arteries.Through a process of regional growth and regression, this vascular plexus is sculpted into the mature coronary artery system we know today.However, any delays in connection to blood flow during this critical development can disrupt downstream vessel formation, leading to anomalous coronary artery anatomy (1).Within the spectrum of coronary artery development, some clinically insignificant variations are considered normal.These variations, essentially the remnants of the dynamic interplay between blood flow and vessel maturation, can present a wide range of geometries.Understanding these variations, including the compensatory adaptations of neighboring coronary branches, is crucial for interpreting coronary artery images and reasoning myocardial perfusion. CLASSIFICATION AND CLINICAL SIGNIFICANCECongenital coronary artery anomalies can be broadly classified into three categories (2):1. Anomalies of origin and course: This includes situations where the coronary arteries arise from unexpected locations or follow unusual pathways.2. Anomalies of intrinsic anatomy: These involve abnormalities within the vessel wall itself, such as myocardial bridging, where a segment of coronary artery dips into the heart muscle.

Jongmin Lee (2024) conducted an editorial in Congenital Coronary Artery Anomalies. Coronary CT angiography (CCTA) vs. Invasive coronary angiography (ICA) was evaluated. Coronary CT angiography is increasingly recognized as the preferred first-line modality over invasive coronary angiography for identifying and evaluating congenital coronary artery anomalies.
