Left ventricular outflow tract calcification: Does the geometry matter?

Abstract

Key Points The CoreValve Evolut PRO/PRO + adapt to left ventricular outflow tract (LVOT) calcification by eccentric deformation at the level of the inflow while preserving circularity at the waist, leaflet tips, and outflow. The CoreValve Evolut PRO/PRO + maintain their favorable hemodynamics and sealing in the short term despite the presence of LVOT calcification. The effect of eccentric inflow deformation in the long term and geometric comparison of self‐expanding valves and balloon‐expandable valves require further investigation.
