Severe aortic stenosis (AS) causes chronic pressure overload of the left ventricle (LV), resulting in progressive cardiac change that can extend beyond the LV. A new AS staging classification has been recently proposed encompassing the extent of cardiac changes in AS. The AS staging classification has important prognostic implications for clinical outcomes after aortic valve replacement. This article introduces the AS staging system and demonstrates the association of the extent of cardiac change with outcomes after transcatheter aortic valve replacement.
