NUMERICAL MODELLING OF STENTING PROCEDURES IN CORONARY BIFURCATIONS: A STRUCTURAL AND FLUID DYNAMIC COMBINED APPROACH

摘要

Starting procedures give the opportunity to treat cardiovascular diseases with a time saving, cost effective and minimally invasive procedure if compared to coronary artery by-pass, ensuring at the same time better clinical results than balloon angioplasty. Despite their success, stenting procedures are still associated to some clinical problems like sub-acute thrombosis (ST) and in-stent restenosis (ISR) whose main outcome is the re-narrowing of the coronary vessels and the necessity of a new treatment to restore blood flow and perfusion to downstream tissues.
