The incorrect description is: the epicardium is also considered the parietal pericardium.
The epicardium is the outermost layer of the heart wall and it is the same as the visceral layer of the pericardium. Visceral layer is one of the two layers of the serous pericardium (other is parietal) which covers the heart. Visceral is the inner layer, while parietal is the outer.
