The anterior interventricular sulcus (or anterior longitudinal sulcus) is one of two grooves that separates the ventricles of the heart, the other being the posterior interventricular sulcus.

The anterior interventricular sulcus is situated on the sternocostal surface of the heart, close to its left margin.

The anterior interventricular branch of the left coronary artery runs in the sulcus along with the great cardiac vein.

Chambers

Right heart	(venae cavae, coronary sinus) → right atrium (atrial appendage, fossa ovalis, limbus of fossa ovalis, crista terminalis, valve of inferior vena cava, valve of coronary sinus) → tricuspid valve → right ventricle (infundibulum, moderator band/septomarginal trabecula) → pulmonary valve → (pulmonary artery and pulmonary circulation)

Left heart	(pulmonary veins) → left atrium (atrial appendage) → mitral valve → left ventricle → aortic valve (aortic sinus) → (aorta and systemic circulation)
