Abstract/OtherAbstract:
Quantifying arterial residual deformations is critical for understanding the stresses and strains within the arterial wall under physiological or pathophysiological loading conditions. This study presents novel findings on residual shear deformations in the left anterior descending coronary artery. Residual shear deformations were most evident when thin, long axial strips were cut from the artery. These strips deformed into helical configurations when placed in isotonic solution. A residual shear angle was introduced as a parameter to quantify the residual shear deformations. Furthermore, a stress analysis was performed to analyze the effects of residual shear deformations on the intramural shear stress distribution of an artery subjected to pressure, axial stretch, and torsion using numerical simulation. The results from the stress analyses suggested that residual shear deformations could significantly modulate the intramural shear stress across the arterial wall.
