What is an Intravascular Ultrasound?
An intravascular ultrasound is a test that uses sound waves to see inside the coronary arteries. A probe is inserted into either a vein or an artery and then manipulated into the vessels. A computer measures how the sound waves reflect off blood vessels and then changes those sound waves into high resolution pictures. Intravascular ultrasound images can produce crisp images of the artery walls and can also reveal cholesterol and fat deposits, which can increase the risk of a heart attack.
What to Expect
You may be instructed not to eat or drink anything after midnight the night before your catherization. Plan to arrive at least an hour prior to your appointment at the hospital. A local anesthetic will be given and the catheter will be gently guided toward your heart. Your doctor will watch the advancement of the catheter on a video monitor, and throughout the procedure dye will injected into the catheter to help visualize your heart chamber and arteries. Higher resolution images will be obtained through the intravascular ultrasound catheter. After the test, the catheter is completely removed, and a bandage is placed on the area. You will usually be asked to lie flat on your back for a few hours after the test to prevent bleeding.
