She has septal hypertrophy (Figure 1 and see VIDEO 1 in Supplementary Material available online at doi10.5402/2011/346797), and she does not have systolic anterior movement of mitral valve (SAM) or intraventricular gradient (VIDEO 1 and VIDEO 2). 
Flow evaluated with continuous wave Doppler at peak exercise demonstrating the absence of LVOT obstruction.
