Representative cases. In a patient, a marked vortical flow (dotted line and curved arrow) was observed before TAVR, and b vortical flow was decreased after TAVR. In another patient, c marked helical flow (dotted line and curved arrow) was observed before TAVR, and d helical flow disappeared after TAVR. TAVR transcatheter aortic valve replacement
