The simulation scenario involved Mr Bright who had just undergone an angioplasty. A potential problem related to this procedure includes impaired tissue perfusion related to haematoma formation or bleeding. 

A potential problem related to this procedure includes impaired.

Sure, I can help you find seven contemporary, valid research journal articles related to the care of patients undergoing angioplasty. Here are some article suggestions:
