Anterior view of the heart (Latin)

The facies anterior cordis faces anterosuperiorly and bears a profound right convexity compared to the left. The ventriculus dexter occupies about two-thirds of its extent, while the ventriculus sinister makes up the remaining one-third. The atrium sinistrum is mainly obscured by the roots of the aorta and truncus pulmonalis, with only a small part of the auricula sinistra projecting. The atria and ventriculi cordis are separated by a deep groove called the sulcus coronarius (atrioventricularis) that contains the largest of the cardiac vessels; it is interrupted anteriorly by the radix trunci pulmonalis. The anterior surface is marked by another groove, called the sulcus interventricularis anterior, that separates the ventriculus sinister and dexter and contains the a. and v. interventricularularis anterior. In this image one can also visualize the outline of the facies dextra cordis, which is longer and more protuberant than the facies sinistra cordis, and is formed by the atrium dextrum superiorly and ventriculus dexter inferiorly.
