Simulations of fluxes in diseased coronary network using an electrical model

In this work, we propose a model of the coronary circulation based on hydraulic/electric analogy. This model aims to provide quantitative estimations of the distribution of flows and pressures across the coronary network for patients with stenoses of the left main coronary artery, left anterior descending artery and left circumflex branch, and chronic occlusion of the right coronary artery, undergoing off-pump coronary surgery. The simulations allow to study the influence of the severity of native artery stenoses, of the degree of collateral supply developed by the patient and of the revascularization status (no grafts, left grafts only, complete revascularization).
