Coronary stenting is a way to open a blocked artery in the heart. During an angioplasty, a mesh, metal tube is placed in the artery. The tube is called a stent.
There are 2 types:
- Drug eluting—Coated with a medicine that is slowly released. The medicine lowers the chances of another block in the same place.
- Bare metal—Has no medicine.

Problems from the procedure are rare, but all procedures have some risk. Your doctor will review possible problems such as:
- Bleeding where the catheter goes in
- Damage to the artery wall
- Heart attack or abnormal heart beats known as arrhythmias
- Reaction to the x-ray dye
- Blood clots
Sometimes the stent isn’t enough or the artery narrows again. This may result in another procedure.
Your chances for problems are higher for:
- Bleeding problems
- Older age
- Recent pneumonia
- Recent heart attack
- Kidney disease
