Dude without a heart...

most likely he must be careful not to over exert himself on anything that may normally raise a heart rate. i don't think it's smart enough to compensate for anything like that yet.
 
How does the device know to increase blood flow when exerting yourself?

I would imagine that there are severe limitations, like not being able to do any strenuous activity (even sitting up too fast or climbing too many stairs might be too much), but as a trade-off for getting another shot at life in general, that doesn't sound so bad to me.
 
Looking at the chest Xray, it does not appear that they removed the heart but placed the device within the heart. His amyloidosis has rendered his heart immobile so its more scar tissue than living myocardium, but the soft tissue shadow on the CXR suggests that this tissue is still there.

I know you are a physician, but I do see the muscle.

Sorry, you do or don't see the muscle. The shadow esp lateral to the left device is about 2-4 cm wide, this suggests that some tissue remains in place, it appears solid not fluid density so I think it is remnants of heart muscle. The device appears to cross the mitral and tricuspid valves so they mostlikely were removed. I suspect that also the sinus and av nodes were ablated to prevent any contractions. With these proceedures it would mostlikely not be necessary to remove the actual myocardium.
