(A, B) Cardiac MRI performed after recovery of ventricular function, on day of illness 23, under general anesthesia. Steady state free precession imaging. Four chamber (A) and LVOT (B) views. The wall thickening was most prominent along the ventricular septum (1.2 cm, white arrows) with some extension to part of the superior wall, compared to the lateral wall which measures 0.5 cm (black arrows). On the four chamber view a small pericardial and left pleural effusion are observed (asterisks). LVOT = Left Ventricular Outflow Tract.
