Coronary Arteries

Description

Anteriorly, a semi-transparent male heart is rendered with the right atrium and right ventricle positioned to the viewer’s left and the left ventricle forming the left-sided, inferolateral apex. A contrast-colored coronary tree courses in the epicardial fat along the atrioventricular and interventricular grooves, with the right coronary artery tracking in the right atrioventricular sulcus and the left main coronary artery dividing into the anterior interventricular (left anterior descending) and circumflex arteries. Branch arterioles spread distally over the ventricular surfaces, while the ascending aorta and proximal pulmonary trunk sit superior to the ventricles and frame the origins of the coronary circulation. Yellow conduction pathways overlay the myocardium, consistent with the sinoatrial and atrioventricular nodal axis and the ventricular bundle branches. Coronary anatomy reads differently when you can see it in relation to chambers and grooves, and this frontal, slight left-oblique perspective favors the territory most discussed in acute coronary syndromes. LAD occlusion, for example, threatens the anterior wall and interventricular septum, so correlating the anterior interventricular sulcus with the left ventricular outflow tract and septal myocardium helps when you are mapping ST-elevation patterns to culprit lesions. Color separation between vessels and conduction tissue also supports teaching why ischemia near the AV nodal artery can present with bradyarrhythmias or varying degrees of heart block. Clear landmarks. Few distractions. Use this asset for gross anatomy and cardiovascular physiology lectures, catheterization lab education on coronary dominance and lesion localization, or as a figure in journals and textbooks discussing myocardial infarction, coronary bypass planning, and arrhythmia mechanisms tied to perfusion territories. It also fits patient-facing cardiology materials that need an x-ray style vascular overview without sacrificing Terminologia Anatomica naming.
