Imaging findings
Cardiac MRI in end-diastole showed a significantly increased ratio of non-compacted to compacted myocardium (3.2:1). There was significant thinning of the compacted portion of the left ventricle as the non-compacted portion became thicker. Ejection fraction (EF) was 48%. No enhancement was noted.
Key takeaways
This was a clinically relevant case of Left Ventricular Non-Compaction in a 60-year-old patient presenting with syncope, also with a history of recurrent embolic strokes. It highlights that incidentally detected LV trabeculations in asymptomatic patients may not deteriorate, but symptomatic presentations are significant. The compacted portion of the LV thins in inverse relationship to the non-compacted portion.
