Figure 1: Subaortic membrane evaluation by TEE. (a) Midesophageal (ME) aortic valve long-axis view showing subaortic membrane with prominent subaortic septal hypertrophy, (b) Color doppler assessment of left ventricular outflow tract in ME aortic valve long-axis view showing turbulent flow at the level of subaortic membrane; (c) 2–D image of subaortic membrane in ME 5-chamber view; (d) Color doppler showing turbulence in left ventricular outflow tract originating near subaortic membrane (LA: left atrium; LV: left ventricle; RV: right ventricle; AO: aorta)
