Three-dimensional wall shear stress images before and a week after ASA. The peak systolic WSS was visualized before (a) and a week after ASA (b). Area-averaged peak systolic WSS was calculated in WSSouter and WSSinner curvatures of the ascending aorta (see the dividing white line). Abbreviations: ASA, alcohol septal ablation; WSS, wall shear stress; WSSinner, wall shear stress at inner curvature of aortic arch; WSSouter, wall shear stress at outer curvature of aortic arch
