Novel apical-to-femoral rail technique for horizontal aorta in transcatheter aortic valve replacement

Transcatheter aortic valve replacement(TAVR)has emerged as a viable treatment option for patients with severe aortic stenosis regardless of its surgical risk stratification(Otto et al.,2021).Aortic angulation is usually measured as the angle between the horizon-tai and the aortic annulus planes based on preprocedural multidetector computed tomography(MDCT)(Al-Lamee et al.,2011).Extremely horizontal aorta,defined as an aortic angulation greater than 70°.
