Figure 4. Echocardiographic studies in parasternal long (A) and short (B) axis projections illustrating severe thickening of the inter-ventricular septum (arrows), suggestive of hypertrophic cardiomyopathy. Continuous wave and color Doppler studies demonstrated elevated Doppler flow velocity across the left ventricular outflow tract at the level of thickened inter-ventricular septum (not shown). Aorta (Ao), left atrium (LA), and left ventricle (LV) are marked. Modified from Ref.^[3].
