The pericardium is a double-walled sac that contains the heart and the roots of the great vessels. The outer wall of the pericardium is composed of dense connective tissue. The portion of the inner wall of the pericardium that is in contact with the heart (but not in contact with the great vessels) is the epicardium. The epicardium contains the blood vessels supplying blood to heart muscle (the coronary arteries) as well as nerve fibers.

Los Angeles Coronerâs spokesman Craig Harvey confirmed that neuropathology tests will be carried out to see if it holds any clues to the exact cause of his death.
