The left coronary artery arises from the left posterior quadrant of the proximal bulbus cordis, while the right coronary artery arises from the right side. It is now understood that coronary arteries develop within the epicardial atrioventricular and interventricular grooves and that their proximal parts grow into the aortic valve sinuses. After the completion of aorto-pulmonary disjunction, the coronary buds and the in situ vascular networks fuse and the coronary circulation will begin to provide blood supply to the myocardium. They are the primitive sites of metabolic exchange between the blood in the cardiac cavities and the cardiac mesenchyma.ДЄt this stage, the bulbus cordis has yet to separate into the aorta and the pulmonary artery (PA) and the two coronary arteries arise from this undivided proximal part: The points of origin of the coronary buds are located so that, with the subsequent division of this portion, they will be situated on the right and left sinuses of Valsalva (RSV and LSV). The sinusoids are an extension of the trabeculae of the spongiosa into the developing myocardium, formed in the subepicardial space in the first weeks of fetal development. AO: Aorta PA: Pulmonary artery B: Coronary buds S: Stems of right, circumflex and left anterior descending coronary artery Sin: Sinusoids. Schematic representation of the components involved in the embryogenesis of coronary arteries. Moreover, it is important to also identify variants and anomalies without clinical relevance in their own right as complications during surgery or angioplasty can occur. The clinical symptoms may include chest pain, dyspnea, palpitations, syncope, cardiomyopathy, arrhythmia, myocardial infarction and sudden cardiac death. Based on the functional relevance of each abnormality, coronary artery anomalies can be classified as anomalies with obligatory ischemia, without ischemia or with exceptional ischemia. Although congenital coronary artery anomalies are relatively uncommon, they are the second most common cause of sudden cardiac death among young athletes and therefore warrant detailed review. We have divided this article into three groups, according to their frequency in the general population: Normal, normal variant and anomaly. Extensive iconography supports the text, with particular attention to images obtained in vivo using non-invasive imaging. The aim of this review is to give a comprehensive and concise overview of coronary embryology and normal coronary anatomy, describe common variants of normal and summarize typical patterns of anomalous coronary artery anatomy.
