Right Coronary Artery, Anterior View

Description

Arising from the right aortic sinus, the right coronary artery courses between the right atrial appendage and the pulmonary trunk before entering the right atrioventricular (coronary) sulcus. From there it runs inferiorly along the acute margin of the heart toward the crux, giving off right atrial branches, the conus branch to the infundibulum, and a right marginal artery that descends toward the apex on the anterior surface of the right ventricle. Superficial cardiac veins accompany the epicardial arterial network in parallel, and the aortic root sits superior and slightly posterior to the proximal coronary origins. That anterior pathway matters because it mirrors what you identify during coronary angiography and what surgeons protect during right atriotomy, tricuspid valve exposure, or bypass grafting. Proximal RCA occlusion commonly produces inferior wall myocardial infarction and may compromise the sinoatrial node artery or atrioventricular nodal branch depending on dominance, a practical link between surface anatomy at the crux and bradyarrhythmias. Dominance patterns are easier to teach when the vessel’s turn toward the posterior interventricular sulcus is anticipated from the anterior course. A key landmark. Use this artwork for cardiology and gross anatomy teaching sessions on epicardial coronary distribution, for interventional radiology primers that pair surface anatomy with catheter-based views, or for publisher layouts discussing acute coronary syndromes, right ventricular infarction, and CABG target selection along the right atrioventricular groove.
