This led to bleeding in the sac around the heart (not up on my anatomy terminology)
The pericardium.

When you've got a foreign-object sticking in you, leave it there!! (exept when in the airways).
Remove it, and there's a large possibility that it will cause a large hemorage (???) leading to death.
In Steve's example, CPR couldn't help him anymore. If what Simon say's is true, he just blead out.
