Coronary Stent

Overview

Definition

In coronary stenting, a mesh, metal tube is placed in an artery in the heart. The tube is called a stent. It helps to keep the artery open. It is placed after an artery has been cleared of blockage during an angioplasty .

There are 2 types of stents. One is called a drug-eluting stent. It is coated with a medication that is slowly released. The medication helps decrease the rate of reblockage in the artery. The other type of stent is called a bare-metal stent. It does not contain any medication. Your doctor will discuss which stent option is best for you.

Possible Complications

If you are planning to have a stent, your doctor will review a list of possible complications. These may include:

  • Bleeding at the point of the catheter insertion
  • Damage to the walls of arteries, causing you to need additional procedures or surgery
  • Heart attack , or abnormal heart beats known as arrhythmia
  • Allergic reaction to x-ray dye
  • Blood clot formation
  • Infection
  • Stroke

Sometimes the procedure is not successful or the artery narrows again. You may require repeat angioplasty or coronary artery bypass grafting (CABG).

Factors that may increase the risk of complications include:

  • Allergies to medications, shellfish, or x-ray dye
  • Obesity
  • Smoking
  • Bleeding disorder
  • Increased age
  • Recent pneumonia
  • Recent heart attack
  • Diabetes
  • Kidney disease
