To the Editor: Isolated noncompaction of the ventricular myocardium is a rare congenital disorder. We have reported elsewhere that the incidence of this unique cardiomyopathy is 0.05 percent in adults.¹ In the report of the 1995 World Health Organization–International Society and Federation of Cardiology task force on the definition and classification of cardiomyopathies, noncompacted myocardium has been categorized as unclassified cardiomyopathy.²

Noncompaction refers to the arrest of compaction of the loosely interwoven meshwork of myocardial fibers during embryogenesis.³ The loose meshwork becomes more compact toward the epicardial surface and condenses to a compact wall, and the intertrabecular recesses communicating with . . .
