oh, okay. But isn't the epicardium part of the pericardium?

epicardium has dual role, functions as the outermost layer of heart wall as well as innermost layer of heart covering (Visceral layer of serous pericardium)

so heart wall - from innermost - endocardium (covers the valves also and is continuous with endothelium of blood vessels)
Myocardium
epicardium
heart coverings (pericardium) from innermost - Visceral layer of serous pericardium (same as epicardium)
Parietal layer of serous pericardium (separated from visceral layer by pericardial space and fluid)
Fibrous pericardium

Ok, thank you!
