Figure 3. Echocardiogram and cardiac magnetic image resonance in the proband. Panels A and B show parasternal long axis view of the ventricles in diastole (panel A) and systole (Panel B). The left ventricular end diastolic and systolic diameters were measured 5.64 and 4.47 cm, respectively, and a calculated left ventricular fractional shortening of 21%. Panel C shows myocardial tissue Doppler velocities depicting low velocities. Panel D shows cross sectional myocardial images obtained by magnetic resonance imaging, which shows enlarged ventricles and absence of fibrofatty infiltration of the myocardium.
