What is the most anterior chamber of the heart?

Explanation:
The most anterior chamber is the right ventricle. The sternocostal (anterior) surface of the heart is formed mainly by the right ventricle as it lies directly behind the sternum and projects forward toward the chest wall. The right atrium sits more to the right border and toward the posterior aspect of the heart, while the left ventricle forms the posterior surface and apex, with the left atrium located more posteriorly as well. So, when you think of the heart’s front view, the contour is dominated by the right ventricle, making it the most anterior chamber.
