Isolated noncompaction of the left ventricular myocardium: a case report and literature review.

A previously healthy 30-year-old African American male presented to our hospital with diabetic ketoacidosis as his first manifestation of diabetes. A transthoracic echocardiogram (TTE) was performed with contrast, which showed isolated noncompaction of the left ventricular myocardium (INVM). The case presented here is followed by an extensive review of the available literature.
