Abstract: Atherosclerotic plaques and their rupture cause narrowing or blockage of the coronary arteries and may lead to sudden cardiac death. As a remedy, after a coronary angioplasty, often a stent is implanted to prevent restenosis. Although it was observed that drug-eluting stents can significantly reduce the occurrence of neointimal hyperplasia, in-stent restenosis still occurs, therefore, studying the distribution of the stent struts during patient follow-ups is important. In this paper, we will present new computer methods for automated analysis of strut distribution in monitoring the restenosis and degree of neointimal tissue growth over struts from the intravascular optical coherence tomography data. Our system will be a useful computer-aided monitoring tool for follow-up studies of stent implantation in the clinical workflow.
