What is the sternocostal surface of the heart?

The sternocostal surface is the anterior face of the heart that faces the sternum and the upper ribs. It is formed mainly by the right atrium and the right ventricle, which lie closest to the chest wall. The other surfaces are different: the diaphragmatic surface forms the bottom and rests on the diaphragm, mainly from the left ventricle; the posterior surface toward the spine is largely the left atrium (with some right atrial contribution); and the base is the broad posterior aspect formed largely by the left atrium. So, this surface corresponds to the front of the heart facing the sternum and ribs.
