WebLeaflet motion was restricted in 37%. Mitral stenosis was present in 28%, and the extent of calcification was associated with mean mitral valve gradient (P < .0001). MR was prevalent (present in 81%) but was severe in none. The severity of MAC was greater in patients with moderate MR than in those with no or mild MR (P = .04). Web19 de ago. de 2024 · This displacement results in leaflet slack; the mitral valve subsequently moves toward the septum, resulting in systolic anterior motion of the mitral valve and causing LVOT obstruction ).
