Abstract

The true cross-sectional shape and dimensions of a coronary arterial wall with an atherosclerotic plaque obtained at postmortem, Fig. 1, is utilized for dilation rupture study related to the balloon angioplasty process. Plane-strain, finite-element analysis [1,2] of the shape changes and stress distributions of the cross section are performed by an incremental loading approach. The location of rupture is predicted by a dilation study ranging from 10 kPa to 120 kPa (about 1.2-fold of atmospheric pressure).
