Role of papillary muscle position and mitral valve structure in systolic anterior motion of the mitral leaflets in hyperdynamic left ventricular function

Role of papillary muscle position and mitral valve structure in systolic anterior motion of the mitral leaflets in hyperdynamic left ventricular function

In conclusion, the principal precursors of SAM in the presence of hyperdynamic LV function include longer anterior and posterior mitral leaflets and anteriorly displaced papillary muscles that poorly support the surplus leaflet tissue.
