|Coronary Angioplasty and Stenting (PCI)|
CORONARY ANGIOPLASTY AND STENTING:
What do angioplasty and stenting do?
Angioplasty is a non-surgical treatment designed to open clogged arteries. This procedure is done after the doctor has seen the angiogram (picture) that shows where the arteries are blocked. Angioplasty, with or without stenting, opens the arteries to restore blood flow to areas of you heart that are at risk. Stenting involves implanting a metal tube (stent) into an artery during an angioplasty. The stent provides scaffolding to hold the vessel open to improve the flow of blood to the heart.
Should I take my medications the day of the test?
Take your medications as directed by your physician unless specifically requested to hold them prior to procedure.
Where is the catheterization performed and who performs it?
· Cardiac catheterizations are performed in the Cardiac Catheterization Laboratory. Catheterizations are performed by specially trained cardiologists and they are assisted by highly skilled registered technologists and registered nurses.
What happens the day of the angioplasty?
The procedure is done in a catheterization laboratory (cath lab). It begins with a thin, flexible tube (the catheter) that the physician inserts through a sheath (previously inserted) in your arm or leg and maneuvers toward your heart.
A non-toxic dye is injected to make it possible for the physician to visualize the coronary arteries. In addition, blood pressure recordings may be made in the various chambers of your heart, and valve function can be examined. Pictures will be taken with specialized cameras.
A few stitches may be used to close the insertion site if an arm artery or vein is used. If a groin site is used, the sheath is left in place for several hours to keep the site from bleeding and to allow the doctor to check the artery if needed. Once the sheath is removed, pressure is applied to the site for 10-20 minutes and a pressure bandage is applied.
In many cases, better results can be obtained if the cardiologist inserts a stent into the area of the blockage and expands it with the balloon. A stent is an expandable wire mesh tube, sized to fit your artery. Once in place, a stent can provide a better channel for blood flow through the artery, with a better long-term result.
What happens after the angioplasty/stent?
You will be asked to drink plenty of fluids to help flush the dye contrast out of your system. Later, when the sheath is removed, a sandbag or pressure bandage will be placed on the insertion site to prevent bleeding. You will remain lying down for several hours and will likely remain hospitalized overnight.
What can I do when I return home?
Avoid heavy lifting and do only light activities for a few days.
Call your doctor if:
How will I feel after the angioplasty?
Your doctor will talk to you about the amount of improvement in the artery opening and the possibility of your symptoms returning, medications, restrictions, and changes in daily habits to reduce the risk of more arteries narrowing. You'll also be told when to return for follow-up visits.
