Serial streamline images in ascending aorta before and a week after ASA. The vortex flow (white arrows) appeared in the mid-ascending aorta in the late systole to early diastole both before (a) and a week after ASA (b). In images before ASA, the vortex flow changed to helix flow (yellow arrows) at mid diastole and continued to late diastole (a). In contrast, the vortex or helix flow disappeared in mid to late diastole after ASA (b). The cardiac phases started from early systole (phase 1) and ended at late diastole (phase 20). Abbreviation: ASA, alcohol septal ablation
