On cMRI, there was severe biventricular dilatation with a left ventricular end-diastolic volume of 137 mL/m2 and a right ventricular end-diastolic volume of 124 mL/m2 cal culated using Simpson's method (Fig. 2). The LA area in the four-chambered view was measured to be 38 cm2, while the volume was noted to be 203 mL (Fig. 2).
(A) 2-chamber LGE imaging devoid of any enhancement. (B) 4-chamber LGE imaging devoid of any enhancement. (C) Sagittal 2-chamber LGE imaging devoid of any enhancement.
