Key result
Computer simulations demonstrated that the curvature of bend significantly affects wall shear stress and pressure drop in curved arteries with two moderate stenoses.
Computational modeling demonstrates that bend curvature and distal stenosis location significantly impact hemodynamic parameters like wall shear stress and pressure drop in right coronary arteries with multiple stenoses.
Bend curvature may influence hemodynamic assessment in moderate stenoses; leaves open effects on clinical decision-making.
In this study, various models with different curvatures of bend and different inter-stenotic distances are created. The computations are carried out and the numerical results are compared with the computer simulation in a right coronary artery model reconstructed using the basic information from a coronary artery segment of a patient. Our results show that the curvature of bend significantly affects the wall shear stress (WSS) and the pressure drop (PD) in curved artery with two moderate stenoses. The location of the distal stenosis strongly influences the flow pattern downstream, while the effect of the location of the proximal stenosis is insignificant.

Biyue Liu (2022) studied Right coronary artery stenoses. Curvature of bend and inter-stenotic distances was evaluated on Wall shear stress (WSS) and pressure drop (PD). Computer simulations demonstrated that the curvature of bend significantly affects wall shear stress and pressure drop in curved arteries with two moderate stenoses.
