During the Procedure
- A stent, which comes mounted on a balloon-tipped catheter, is delivered to the blockage in your artery.
- The balloon is then inflated, causing the stent to expand.
- The expanded stent further compresses the plaque against the arterial wall, increasing the blood flow to the heart muscle.
After the Procedure
- You may need to keep still, with your leg or arm straight, for 2–6 hours. How long depends partly on where the catheter was inserted and how the site was closed.
- If the insertion site was in your groin, you may need to lie down with your leg still for several hours.
- A nurse will check your blood pressure and the insertion site.
- You may be asked to drink fluid to help flush the contrast liquid out of your system.
- Have someone drive you home from the hospital.
- It’s normal to find a small bruise or lump at the insertion site. This should disappear within a few weeks.
When to Call Your Doctor

- Angina (a feeling of pain, pressure, aching, tingling, or burning in the chest, back, neck, throat, jaw, arms, or shoulders).
- Increasing pain, swelling, redness, bleeding, or drainage at the insertion site
- Severe pain, coldness, or a bluish color in the leg or arm that held the catheter
- Shortness of breath
- Difficulty urinating or blood in your urine
- Fever over 101°F.
