Interventional Cardiology

Balloon angioplasty

is a procedure performed by cardiologists to help open narrowing in the coronary arteries. This procedure requires passing a catheter with a balloon into the artery. The balloon is then inflated in the artery to eliminate the narrow area.

Atherectomy (Rotorooter)

a procedure for opening coronary arteries blocked by plaque. Atherectomy uses a rotating shaver, ("burr" device on the end of a catheter). The catheter is inserted into the body the same way as in angioplasty. The burr then shaves the plaque, opening the artery.


is a wire mesh tube used to keep clear an artery, opened using angioplasty. The stent is collapsed placed over a balloon catheter. It is placed in the area of the blockage; inflating the balloon then deploys the stent. The stent forms to the artery like scaffolding, keeping it from closing.
