Angles between the aortic root and the left ventricle assessed by MDCT are associated with the risk of aortic regurgitation after transcatheter aortic valve replacement

Objectives To evaluate the impact of the angles quantified by multidetector computed tomography (MDCT) between the ascending aorta’s long axis and, the left ventricular inflow long axis (LVLA), or the left ventricule outflow tract long axis, and the occurrence of post-transcatheter aortic valve replacement (TAVR) aortic regurgitation (AR).
