Anatomical terminology [edit on Wikidata]

The anterior interventricular sulcus (or anterior longitudinal sulcus) is one of two grooves separating the ventricles of the heart (the other being the posterior interventricular sulcus). They can also be known as paraconal interventricular groove or subsinosal interventricular groove respectively. It is situated on the sternocostal surface of the heart,^[1]^[2] close to the left margin of the heart.^[2] It extends between the coronary sulcus, and the apex of the heart;^[1] upon reaching the diaphragmatic surface of the heart, it ends at the notch of cardiac apex.^[3] It contains the anterior interventricular branch of the left coronary artery, and great cardiac vein.^[1]^[2]

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, crista supraventricularis), → 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)

Myocardium	Conduction system cardiac pacemaker SA node Bachmann's bundle AV node bundle of His bundle branches Purkinje fibers
