Cardiac Catheterisation is used to confirm CAD and locate the exact site of a blockage.  Depending on your results, catheters may also be used to improve blood flow.  Your doctor will talk with you about the risks of all catheter-based procedures.  You’ll also be told how to prepare.

Being well prepared can help you feel more at ease on the day of your procedure. 
Be sure to:

• Take medication as instructed by the doctor performing your procedure.  New medications may be prescribed or you may be asked to stop taking certain medications for a period of time.
• Do not eat or drink after the midnight before the procedure.
• Arrive at the hospital a little early.  You will be asked to read and sign consent forms.
• Arrange for an adult family member or friend to take you home after the procedure.  But be aware that you may need to stay in the hospital overnight.  Pack a bag just in case.

Complications of Catheter-Based Procedures are fairly rare. 
Still, risks of Cardiac Catheterisation, Angioplasty and Stenting may include: 

• Bleeding from the catheter insertion site
• Allergic reaction to the x-ray dye
• Abnormal heartbeat (arrhythmia)
• Tearing of the artery lining
• Kidney failure
• Emergency bypass surgery
• Heart attack, stroke or death

• About any medications you take, Include herbs, supplements and over-the-counter medications.
• If you are allergic to iodine, shellfish or any medications.  X-ray dye used during catheter based procedures contains iodine.  If needed, you can be given medication to prevent an allergic reaction.
• If you are pregnant or think you could be pregnant.  The procedure may be postponed until after the baby is born.
