[Benson 2020;1a] Furthermore, amyloid deposition can occur in any heart tissue, including the endocardium, valves, myocardium, epicardium and parietal pericardium. However, the deposition in the ...

The formation of the heart depends on critical signals exchanged between its two main layers: the myocardium (the muscle that powers the heartbeat) and the endocardium (the inner lining of the heart).

The epicardium is the outer ... is the middle and thickest layer, including heart muscle cells that pump blood. The inner layer, known as the endocardium, lines the chambers and valves.
