Improvement of haemodynamic stent strut configuration for patent ductus arteriosus through computational modelling
CurTently, the treatment of Patent Ductus Arteriosus (POA) by the implantation of coronary stent has resulted in severe hemodynamic complications. There is thus a need to customize and improve current stent geometry specific to POA to overcome this problem. Computational Fluid Dynamics (CFO) approac...
