- •Adults with SM have slower hemodynamic progression and more rapid AS progression.
- •Changes in LVOT velocities are minimal over time.
- •Presence of SM with AS poses challenges in determining hemodynamic significance.
- •In general, surgery should be recommended when AS is severe and symptoms develop.
