P1842Impact of left ventricular outflow tract sphericity on transcatheter heart valve hemodynamics and outcome after transcatheter aortic valve implantation

Background Accurate assessment of aortic annulus and left ventricular outflow tract (LVOT) anatomy is mandatory for appropriate device selection in order to achieve optimal deployment of transcatheter heart valves (THV). Aim To evaluate the impact of LVOT shape as determined by the sphericity index (ratio of long and short LVOT diameter) on THV hemodynamics. Methods 1000 consecutive patients diagnosed with severe symptomatic aortic stenosis and...
