Intravascular Imaging

Why Intravascular Imaging?

A revolutionary imaging tool that gives a clear understanding of your blood flow condition.

Intravascular Imaging

Overview

Intravascular Imaging is a technique that helps your cardiologist to get inside the artery. This is done with a camera-like device that provides a real-time view of the artery of heart. It gives information like severity of blockage, abnormalities like calcium, dissection and thrombus. It can also be used in planning for the insertion of stents.

During the procedure, the cardiologist will make a small incision in your groin to gain access to a large artery. Your cardiologist, with a slim guide wire, will gently advance the wire to the arteries of your heart. There are three ways that this technique is executed:

  • IVUS (Intravascular Ultra Sound)
  • OCT (Optical Coherence Tomography)
  • FFR (Fractional Flow Reserve)

What Can Indicate That I Need Intravascular Imaging?

If you have significant blockages or leakages or narrowing that can hinder the blood flow, that could mean you may need an angioplasty. It is indicated in patients who needs complex angioplast like CTO intervention, Calcified coronary arteries, Bifurcation lesions & multi vessel disease. If a coronary artery becomes partially blocked, it can hinder the oxygen supply to areas of the heart. This can result in a heart attack. Some of the common reasons to see a doctor can be:

  • Experience of chest pain
  • Shortness of breath
  • If you already have a survival history of heart attack
  • Significant narrowing in arteries even after previously administered graft surgery
 

If you have any such symptoms, the doctor might suggest an angioplasty. This would subsequently mean, that you have to undertake Intravascular Imaging in Basavanagudi.

Intravascular Imaging FAQs

The doctor might suggest angioplasty if you have the following symptoms:

  • Experience of chest pain
  • Shortness of breath
  • If you already have a history of heart attack
  • Significant narrowing or hindrance in blood flow

             This would subsequently mean that you have to undertake Intravascular Imaging.

It is a minimally invasive procedure used to get images from inside the arteries. This is usually done under conscious or minor sedation. During the process, your cardiologist will make a small incision in your groin to get a large artery. They will insert a very thin guide wire topped with a pressure sensor. Your cardiologist will gently advance the wire to the arteries of your heart. You may feel mild pressure or a slight burning sensation in your chest during this procedure

  • An area of the groin will be shaved and cleaned in preparation for the insertion of a catheter.
  • A mild sedative is
  • administered to aid in relaxation only in elderly and sick patients.
  • The imaging physician directs this catheter through arteries until it reaches the area of interest.
  • A catheter with imaging camera (IVUS/ OCT) is guided to the furthest position to be imaged.
  • The camera sends images to a computer which is then analysed.

It enables a physician to get inside the artery with a camera-like device. It can quantify the percentage of narrowing and give insight into the nature of the plaque. This helps to calculate the extent of the medical care to be administered.

Helps to produce calcifications as bright images with shadowing behind them. Images for the blood vessel wall inner lining, atheromatous disease within the wall, connective tissues, and blood and healthy muscular tissue.

IVUS uses ultrasound and OCT uses infrared lights, but both methods use the same probing technique each has its own advantage for specific type of procedure planned.

FFR uses a pressure sensor probe to calculate blood pressure difference in the artery while IVUS is used to get cross-sectional images with ultrasound. They both are used as compliments for the imaging process.
