This is tissue, which has died due to lack of blood supply (37)


Slide22 l.jpg

Heart: somebody has pressed on top of the hand- a sign of heart failure (36)The left ventricle is towards the left of the screen, and shows enormous thickening of the wall, particularly in relation to the small cavity. The heart is almost twice the size it should be, as it has had to work much harder than normal. (38)
