Coronary Disease: A New Perspective Thanks To Ultrasound

Compared to other techniques, Intravascular Ultrasound (IVUS) is much better at monitoring the increase or decrease of atherosclerosis in the coronary arteries. Can the method even be used to predict the odds of a heart attack or other cardiovascular event? Studies indicate this may be the case, states Professor Clemens von Birgelen in his inaugural address at the University of Twente. Results of IVUS measurements also raise the question of whether patients with demonstrated coronary disease should be treated with more powerful cholesterol-lowering statins to reverse atherosclerosis. Von Birgelen's inaugural address takes place on 5 June.

Narrowed coronary arteries due to atherosclerosis can be visualised using 'classic' cardiac catheterisation, but the technique only shows the space the blood flows through, the 'lumen', and not the diseased vascular wall surrounding it. By using a specialised catheter with an ultrasound 'sensor', IVUS also creates images of the calcifications, the 'plaque', and allows various components of the plaque to be identified not only calcium, but also fat and connective tissue.
