Does catheter insertion alter hemodynamic parameters in stenosed arteries?
Does catheter insertion alter hemodynamic parameters in stenosed arteries?
Computational modeling demonstrates that catheter insertion in severely stenosed arteries significantly exacerbates adverse hemodynamic changes, including increased shear stress and reduced flow rate.
Catheter insertion may worsen hemodynamics in severe stenosis; leaves open clinical relevance pending human validation.
The study of hemodynamics in stenosed arteries is critical for understanding cardiovascular diseases and optimizing treatment strategies. This research explores the hemodynamic alterations caused by arterial stenosis and examines the influence of catheter insertion on these dynamics. Using mathematical modeling and computational fluid dynamics, the study evaluates key parameters such as wall shear stress, pressure drop, and flow velocity profiles under varying conditions. Results highlight significant differences in hemodynamic behavior with and without catheter insertion, emphasizing the implications for clinical practices such as catheter-based interventions.

Kuldeep Maurya (2024) studied Arterial stenosis. Catheter insertion (computational simulation) vs. No catheter insertion was evaluated on Hemodynamic parameters (velocity, pressure gradient, shear stress, flow rate). Computational fluid dynamics simulations demonstrated that catheter insertion in severely stenosed arteries further reduced maximum blood flow velocity to 30 cm/s and increased shear stress to 2.0 Pa.
