The procedural results of transcatheter aortic valve implantation (TAVI) have continuously improved, paralleling an improvement in available technologies, procedural planning and technical execution. However, some anatomical barriers still remain incompletely resolved, since a proportion of TAVI candidates have advanced atherosclerotic disease associated with complex pathological changes of the arterial tree, leading to difficulties in delivering and implanting a transcatheter heart valve (THV).

Increased angulation or unfolding of the aortic root and ascending aorta, often referred to as a “horizontal aorta”, is one of these anatomical challenges, particularly for the transfemoral approach for TAVI. Defined on either ...
