Non-compaction of the left ventricle

Discussion:

There is excessive trabeculation at left ventricular myocardium. 2.3:1 ratio of non compacted to compacted myocardium at end-diastole on SAXs CINE or LONG AXIS at the apex.

Differential diagnosis:

  • apical hypertrophic cardiomyopathy
  • dilated cardiomyopathy
  • late gadolinium enhancement imaging with long inversion time (~ 600 milliseconds) to exclude thrombus
