• What happens during a IVUS? icon plus

  If you have coronary artery disease, your cardiologist might recommend a coronary stent. IVUS is used during the stent procedure to improve the precision of the stent placement and help make sure it's working correctly. You will be awake during the procedure, but may be given a sedative to help you relax.

  Your cardiologist will insert a thin, flexible tube (catheter) into an artery through a small cut in your groin or wrist. Local anaesthetic will be used to numb the area. The IVUS probe is on the end of the catheter, which is guided into your heart. The images provided give your consultant a view inside your artery to help them place the stent.

• How to prepare for your ultrasound icon plus

  Your consultant will explain the procedure to you and answer any questions you may have. They'll let you know how to prepare, including whether you'll need to avoid food or certain medications beforehand. Like all procedures, there may be some risks and side effects involved. Your consultant will explain these to you.

• After your ultrasound icon plus

  You may need to spend one night in hospital after your stent procedure. You should rest for a few days afterwards to allow your wrist or groin area to heal. Your cardiologist will let you know what to expect and will discuss the procedure with you, and let you know when you can get back to your usual routines and activities. They will also give you advice on medication and any necessary lifestyle changes.
