Abstract

Percutaneous coronary intervention such as implantation of a stent (stenting) is the modern gold standard for coronary revas-cularisation. Stenting for a simple lesion has become a common procedure and is highly successful, but stenting for bifurcation lesions is more difficult and requires multiple stent implantations. The presence of the stent struts partially occludes blood flow from the main vessel to the side branch and leads to chaotic flow. As a result, bifurcation coronary stenting is often associated with dreaded complications like in-stent restenosis and thrombosis. Computational fluid dynamics (CFD) simulations were conducted on the classical T-stenting (TS) and reverse Tstenting ..
