As a last resort, surgeons did an extreme procedure called an open thoracotomy which is that crazy tool you see there that basically splits the ribs open and allows easy open access to the heart. They did this so they could give him a cardiac massage. A cardiac massage is when surgeons are manually trying to pump the heart after it has stopped working on its own (cardiac arrest). Unfortunately he lost so much blood from his gun shot wound and he was pronounced dead. There are cases of patients surviving after having this kind of invasive resuscitation but it is rare.

Renal artery stenosis is the narrowing of one or more arteries that carry blood to your kidneys (renal arteries). Narrowing of the arteries prevents normal amounts of oxygen-rich blood from reaching your kidneys. Your kidneys need adequate blood flow to help filter waste products and remove excess fluids. Reduced blood flow may increase blood pressure in your whole body (systemic blood pressure) and injure kidney tissue.
