The leftanterior descending artery was patent. Angioplasty of thedistal right coronary artery resulted in a patent infarct-related artery with near normal flow. A stent was left inplace to stabilize the patient and limit infarct size. Leftventricular ejection fraction was normal at 42%, and aposterobasilar scar was present with hypokinesis."a. Explain angioplasty and stent placement. Defineoccluded occlusion.b. What is the purpose of this medical procedure?
