Intravascular ultrasound (IVUS) is a medical imaging technique that helps doctors to get clear images of blood vessels. In this test, sound waves are used to identify blood vessel issues that affect normal blood flow, such as blockages and narrowing. The IVUS procedure is minimally invasive and uses advanced, fine instruments to provide detailed results while being gentle on the body.
Intravascular ultrasound (IVUS) uses sound waves to examine soft tissue, and look inside the coronary arteries. These arteries supply oxygen-rich blood to the heart muscle. Small instruments take real-time images from inside your blood vessels. This test is commonly used to check arteries and veins near the heart, including the coronary arteries.
It can also be used to examine other blood vessels. The procedure is also called: Coronary intravascular ultrasound', 'endovascular ultrasound', and 'intravascular echocardiography'. In this test, a very thin tube called a catheter is passed through a blood vessel to the heart. This catheter has a tiny ultrasound camera at its tip. The camera sends sound waves that create clear images of the inside of the artery walls.
Coronary artery disease happens when fat deposits (plaque) build up inside the arteries. This condition also reduces blood flow to the heart. It leads to chest pain, shortness of breath, or even a heart attack. Coronary intravascular ultrasound enables doctors to:
The IVUS cardiac procedure is useful when angiography results are unclear. It helps doctors understand whether a blockage needs a stent, medication, or another form of treatment.
Doctors may suggest an IVUS procedure in several heart-related situations. Some common IVUS procedure indications include:

Yes. The IVUS procedure is considered safe when performed by trained cardiologists. It is commonly used worldwide and has a low risk of complications.
Patients may feel mild pressure at the catheter entry site, but pain is minimal. Most patients recover quickly and return to normal activities as advised by their doctor.
No. The IVUS procedure is usually painless, as local anaesthesia is used; patients may feel mild pressure at the catheter site.
Most patients recover within a few hours and can resume normal activities as advised by the doctor.
IVUS is better for viewing deeper artery walls, while OCT provides higher surface detail; the choice depends on the patient’s condition.
Yes. IVUS can detect early plaque buildup inside arteries before severe blockage occurs.
IVUS is generally safe; rare risks include mild bleeding, bruising, or vessel irritation at the catheter site.
Yes. Fasting for a few hours is usually advised before the procedure, as recommended by your doctor.
Yes. IVUS can be used during emergency heart procedures to guide accurate treatment.
IVUS may not be suitable for patients with severe vessel damage or certain medical conditions, as decided by the cardiologist.
