Sternocostal surface of heart

Sternocostal surface of heart.

Heart seen from above.
Latin	facies sternocostalis cordis, facies anterior cordis
Gray's	subject #138 528

The sternocostal surface of the heart (anterior surface of the heart) is directed forward, upward, and to the left.

Its lower part is convex, formed chiefly by the right ventricle, and traversed near its left margin by the anterior longitudinal sulcus.

Its upper part is separated from the lower by the coronary sulcus, and is formed by the atria; it presents a deep concavity, occupied by the ascending aorta and the pulmonary artery.

Anatomy of torso, cardiovascular system: heart (TA A12.1, GA 5.524)

General

Surface	base · apex · grooves (coronary/atrioventricular, interatrial, anterior interventricula, posterior interventricular) · surfaces (sternocostal, diaphragmatic) · borders (right, left) · Openings of smallest cardiac veins

Internal	atria (interatrial septum, musculi pectinati, sulcus terminalis) · ventricles (interventricular septum, trabeculae carneae, chordae tendineae, papillary muscle) · valves · cusps · Atrioventricular septum cardiac skeleton (fibrous trigone, fibrous rings) Intervenous tubercle

Chambers

Right heart	(vena 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 (conus arteriosus, 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)

Layers

Endocardium	Heart valves

Myocardium	Conduction system: Cardiac pacemaker · SA node · AV node · bundle of His · Purkinje fibers

Pericardial cavity	Pericardial sinus

Pericardium	fibrous pericardium (Sternopericardiac ligaments) · serous pericardium (epicardium/visceral layer) · Fold of the left vena cava
