Key result
Repeat CMR identifies isolated LVNC in a 55-year-old man evaluated for syncope.
Why the study?
Isolated non-compaction of the left ventricular myocardium is a rare cardiomyopathy that requires increased awareness for accurate diagnosis.
Case Report (n=1)
Cardiac magnetic resonance is advantageous for diagnosing isolated non-compaction of the left ventricular myocardium in adults presenting with syncope and progressive LV dysfunction.

CMR may aid isolated LV noncompaction diagnosis in syncope with dysfunction; leaves open routine use pending larger studies.
A 55-year-old man evaluated for syncope had mild and gradually progressive left ventricular systolic dysfunction on initial workup. Although not identified initially, repeat cardiac magnetic resonance one year later demonstrated the presence of trabeculations in the left ventricle consistent with the diagnosis of isolated non-compaction of the left ventricular myocardium. This case highlights the need for increased awareness of this entity among primary care physicians, cardiologists, and radiologists in order to enhance its identification. This case also demonstrates the advantages of cardiac magnetic resonance for diagnosis and provides insight into this rare type of cardiomyopathy in adults.

Vásquez et al. (2009) conducted a case report in Isolated non-compaction of the left ventricular myocardium (n=1). Cardiac magnetic resonance was evaluated on Diagnosis of isolated non-compaction of the left ventricular myocardium. Repeat cardiac magnetic resonance identified isolated non-compaction of the left ventricular myocardium in a 55-year-old man initially evaluated for syncope.
