Left ventricular non-compaction is a rare myocardial disorder characterized by prominent left ventricular trabeculae and deep intertrabecular recesses. While most cases are asymptomatic, it presents within a wide spectrumof clinical manifestations including left ventricular dysfunction, ventricular arrythmias, systemic embolization, and sudden cardiac death. Diagnosis is made through imaging studies such as echocardiography and cardiac magnetic resonance imaging. We describe a case of asymptomatic left ventricular non-compaction detected in a patient with no clinical clues outside of a positive family history of sudden cardiac death.
