IVUS (Intravascular Ultrasound)
IVUS is a technique to assess the coronary arteries with a special ultrasound device. Once inserted into the coronary artery, this can show the inside of the arteries clearly to identify the accuracy of the block in the artery and the diameter of the artery. This will guide in decision-making process about the need for angioplasty and also to choose the right size of stent to be used. This will also help to confirm if the stents are deployed properly without leaving space between the stent and the wall of the artery. This is particularly helpful to improve the outcome of the angioplasty in the long run.
