Abstract

With the pericardium opened, the heart (Fig. 252) presents a fixed posterosuperior portion—the atria (auricles); and a free anteroinferior portion—the ventricles. A groove containing fat, the auriculoventricular groove (coronary sulcus), marks the line of separation between atria and ventricles; it contains the right coronary artery. Passing downward and to the left, a similar groove is found which divides the ventricular portion of the heart, as seen in front, into a larger right and a smaller left ventricle. This groove corresponds to the attachments of the anterior margin of the septum between the right and the left ventricles and is known as the anterior inter-ventricular groove (anterior longitudinal sulcus); it contains the anterior descending branch of the left coronary artery. All 4 chambers of the heart are visible from the “front” view; however, only a very small portion of the left atrium is visible: the auricle of the left atrium.
