An angioplasty is an operation to open up blocked arteries. Trillium Health Partners performs more than 2,000 angioplasties per year at our Mississauga Hospital and is the only hospital providing this service in the Halton/Peel Region. 

During the operation a catheter with a special balloon is inserted into your artery at the point of blockage. The balloon is then blown up, compressing the fat or plaque blocking the artery against the arterial walls, widening the passage.
Angioplasty allows more blood to flow through your arteries and more oxygen and nutrients to your heart. It also reduces angina and the odds of having a heart attack.

Patients undergo coronary angioplasties in Mississauga Hospital's Cardiac Catheterization laboratories and recover in the cardiac short stay unit where they stay overnight for observation.

Stop eating and drinking 4 hours before your angioplasty.

Take your pills with a small sip of water.
Follow your doctor's advice about taking your:

  • diabetic pills,
  • Coumadin (Warfarin)

What to Expect During Your Procedure

  • Staff will watch your heart rhythm and blood pressure.
  • A nurse will wash your groin or arm and cover the area with sterile sheets.
  • The doctor will freeze your groin or arm.
  • The doctor puts a tube into your artery which guides a small balloon and stent into the narrowed part of your artery.
  • The doctor moves the small balloon to the narrowed part of your artery. It is inflated (blown up) for about 20 seconds. - You might feel chest pressure or chest pain when the balloon is blown up. This is normal. The feeling will go away once the balloon is deflated and removed.
  • Staff may give you Nitroglycerin during the procedure. This may give you a headache.
  • The stent is placed over a balloon and is directed into the blocked area in your artery.
  • When the balloon is inflated, the stent expands into the artery.
  • The stent stays in place permanently, holding the artery open.
  • The doctor will give you a blood thinner to stop blood clots from forming in your stent. The doctor will tell you how long you will be on this medication.

What to Expect After Your Procedure
You will be taken to recover in one of the following areas:

  • Cardiac Short Stay Unit (CSSU)
  • Coronary Care Unit (CCU)
  • Cath Lab patient area
  • If you are an inpatient, you may go back to your unit.

The heart doctor (cardiologist) will decide how long you will be in hospital. This can vary between 8 to 12 hours for outpatients and a few days for inpatients.
You can have someone visit you while you are resting after the procedure.
Visitors: only 1 or 2 visitors per bedside.

You may have blood work and an ECG done during your hospital stay.
If the tube is in your leg, it will stay there for about 2 to 4 hours. After that time, the nurse will remove the tube, applying pressure to the site for about 20 minutes.
If the tube is in your wrist, it will be removed at the end of the procedure.
You will need to remain in bed for about 2 to 8 hours after your procedure, depending on the access site used.​​
