Echocardiogram of the heart. (a) Apical view demonstrating marked trabeculation of the left ventricular apex (white arrow). (b) It shows contrast agent visualized between the ventricular trabeculations. RA: right atrium; LA: left atrium; LV: left ventricle; RV: right ventricle.

Cardiac evaluation with echocardiogram (Figure 1) showed depressed left ventricular systolic function (ejection fraction (EF) of 30-35%), biatrial enlargement, and increased left ventricular (LV) wall thickness.
Cardiac MRI of the heart. ((a) and (b)) Cardiac MRI of the LV showing prominent muscular trabeculations (asterisk) and spongiform appearance of the ventricular cavities. (c) Short axis cardiac MRI image through the distal RV and LV, demonstrating trabeculations filling the ventricular cavity.

Cardiac MRI (Figure 2) demonstrated the prominent LV trabeculation pattern that was noted on TTE, which forms the classic spongiform appearance on the distal one-third of the LV cavity.
