What is Coronary Stent Implantation?

A coronary stent may be implanted in a coronary artery during an angioplasty procedure to open narrowed or blocked blood vessels in your heart. A stent is a small, metal mesh tube that expands to open up a coronary artery to help prevent the artery from closing again. You may have a stent coated with slow released medication to help prevent future plaque buildup and the artery re-narrowing.

What to Expect

What to Expect During a Coronary Stent Implantation

The angiography procedure will determine the number and locations of your blocked or narrowed arteries. This is where your doctor will implant the stent: 

  • Your doctor will advance a thin wire, and a tiny deflated balloon, through the catheter used during the angiography to the location of your blockage. 
  • The balloon with then is inflated at the targeted blockage to expand the artery where the stent will be advanced and implanted. 
  • After the stent is in position, it will be fully opened and locked in place.  Further X-rays will determine if the stent is function as it should and how much blood flow is improved. 
  • Once your doctor is satisfied that the stent is working, the balloon catheter, guide wire and guide catheter will be removed. 
  • You will probably stay overnight at the hospital after the procedure and you should get someone to take you home once you’re discharged. 
  • Your doctor will give you specific instructions for after care.
