P1D-8 Strain Imaging with Intravascular Ultrasound: An In Vivo Study

Coronary atherosclerosis is a common disease in industrialized countries. Acute coronary syndromes are associated with a high mortality rate. They are usually caused by a sudden occlusion of the coronary lumen due to rupture of unstable plaques in the vessel wall, often with less than 50 % stenosis. Thus, plaque morphology does not give sufficient information for determining the risk of an acute syndrome. However, the mechanical properties of vulnerable coronary plaques were shown to be different from other plaque types. Therefore, IVUS strain imaging can be an important imaging tool for risk assessment of plaques
