Intravascular and near-wall hemodynamic features characterizing coronary arteries pathophysiology by Giuseppe De Nisco, Politecnico di Torino.
Distribution of intravascular helical blood flow features, and topological shear variation index (TSVI) and TAWSS at the luminal surface of healthy (left) and diseased (right) LAD coronary artery. Right-handed (LNH > 0) and left-handed (LNH < 0) helical blood structures are displayed by red and blue, respectively. One explanatory luminal cross-section is reported. The lumen contour is markedly thick for a better visualization of TSVI and TAWSS values at the luminal cross-section edge. Luminal surface areas experiencing high variation in WSS contraction/expansion action along the cardiac cycle (quantified by the TSVI) enclosed the separation region between counter-rotating helical blood flow patterns.
