Conduction abnormalities following transcatheter aortic valve replacement (TAVR) are caused by damage of the aortoventricular conduction tissue during positioning of the valve. Therefore, our aim was to assess whether a higher difference between the long and short diameters of the elliptic aortoventricular annulus will possess higher forces on the annulus, and thus will be a predictor of pacemaker need following TAVR.
