Case of the week 08-07 CMR and echo in LVNC

A

B

History:18 Y/O male presented with dyspnea and palpitations. His father had died suddenly at age 32.

Echocardiogram: Global Hypokinesis and hyper-trabeculation suggestive of non-compaction. (A)

CMR Referral: To establish a diagnosis of left ventricular non-compaction (LVNC).

CMR Interpretation: Dilated hypokinetic left ventricle. Ratio of non-compacted to compacted myocardium at end diastole in the midventricle was 2:1. The hyper-trabeculation was present in anterolateral, lateral, inferolateral, and apical walls sparing the septum. (B,C, & D)

CMR Perspective: The trabecular architecture was better appreciated with CMR leading to a proposed diagnosis of LVNC cardiomyopathy. Although often seen in LVNC, LGE was not observed in this patient.

Clinical Course: The treatment initiated was for DCM and heart failure– although with a lower threshold for warfarin. During his initial evaluation multiple episodes of non-sustained ventricular tachycardia were documented. An AICD was inserted.
