Figure 1. Apical 4-chamber view demonstrating chordal systolic anterior motion (SAM) with an intracavitary gradient at the level of the chordae with turbulent flow through the outflow tract. The yellow arrow indicates the intracavitary flow acceleration through the left ventricle outflow tract (LVOT) due to chordal SAM. The green arrow indicates the anterior mitral leaflets. The red arrow demonstrates the turbulent flow in the LVOT due to chordal SAM before reaching the pulmonic valve.
