The right superior septal artery originates from either the right coronary artery or the right sinus of Valsalva and distributes blood to the superior part of the ventricular septum; thus, it can connect to the septal branches of the left anterior descending artery and serve as a collateral source. In the case presented herein, coronary computed tomographic angiography clearly delineated the right superior septal artery, and coronary angiography demonstrated a collateral connection between the right superior septal artery and the septal branch. This collateral artery prevents myocardial infarction in the anterior and septal walls of the left ventricle. The right superior septal artery is clinically important not only as a collateral source to the left anterior descending artery but also as an access route for percutaneous transluminal septal myocardial ablation in hypertrophic cardiomyopathy.
