Figure 1: Echocardiographic parasternal shortaxis view at the midleft ventricle level during endsystole (a) and enddiastole (b), demonstrating an abnormal flattened septum. Eccentricity index is defined as the ratio of D_{2}/D_{1}, where D_{1} is the LV shortaxis diameter perpendicular to the septum and D_{2} is the left ventricle shortaxis diameter parallel to the septum. (a) EI^{TTE} = 1.44 and (b) EI^{TTE} = 1.44
