Transcatheter aortic valve implantation (TAVI) has been increasingly recognised as a viable therapeutic option in patients with severe aortic stenosis and at high risk for surgical valve replacement1. In order to obtain optimal results during TAVI, valve delivery should be performed under fluoroscopic guidance with three valve cusps aligned. The valve apparatus is, however, a three-dimensional (3-D) anatomic structure, which limits angiographic capabilities to find the ideal alignment between cusps properly. Different strategies to accomplish this key step during TAVI have been proposed: (1) an angiography-based approach, which would probably demand additional contrast volume, time and radiation exposure2; (2) a two-dimensional (2-D) ...
