Lumped parameter model based surgical planning for CABG

Abstract

The current 3D CABG model is time consuming, a lumped parameter CABG model may solve this problem. A coronary lumped parameter model without stenosis and graft was constructed. The stenosis resistance was calculated and graft model was constructed. After calculation, the graft flow results of CABG lumped parameter model fit well with 3D CABG model results.
