The pericardium is thus covered by the pleurae, except over a small bare area on the left at the level of the fourth to sixth cartilages. This is known as the “bare area of Edwards,” or the “cardiac dull space.” The latter term is attributable to the lack of resonance to percussion at this point.

What does the superior border of the heart look like?
The superior border of the heart is a convex line that runs from the inferior border of the second left costal cartilage to the superior border of the third right costal cartilage. The right border of the heart is a convex line that runs from the third right costal cartilage to the sixth right costal cartilage.
