Intravascular ultrasound

Q: What happens during a IVUS?

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.

What is an intravascular ultrasound?

Intravascular ultrasound (IVUS) uses high frequency sound waves to visualize the inside of your coronary arteries.

The ultrasound images are generated in real time and can be used by your consultant to help make sure the correct size coronary stent is inserted and fully expanded, helping to improve blood flow through narrowed arteries.
