Anterior view of the heart (English)

The anterior surface of the heart faces anterosuperiorly and bears a profound right convexity compared to the left. The right ventricle occupies about two-thirds of it extent, while the left ventricle makes up the remaining one-third. The left atrium is mainly obscured by the roots of the aorta and pulmonary trunk, with only a small part of the left auricle of the heart projecting. The atria and ventricles are separated by a deep groove called the coronary (atrioventricular) sulcus that contains the largest of the cardiac vessels; it is interrupted anteriorly by the root of the pulmonary trunk. The anterior surface is marked by another groove, called the anterior interventricular sulcus, that separates the left and right ventricles and contains the anterior interventricular artery and vein. In this image one can also visualize the outline of the right (pulmonary) surface of the heart, which is longer and more protuberant than the left surface, and is formed by the right atrium superiorly and right ventricle inferiorly.
