The passage of a balloon catheter through the lumen of an occluded coronary vessel to compress plaque against the arterial walls is called

angioplasty

Explanation:

Angioplasty is a medical procedure whose main objective is to revascularize the heart. This is done by passing a balloon catheter through the lumen of an occluded coronary vessel to compress the plaque against the arterial walls. With this, it is expected that the blood flow will return to run normally in arteries that were blocked and preventing that blood from flowing normally, which can cause serious problems to the body, because it is necessary that the organs and body tissues are irrigated by the blood that flows in the veins and arteries.
