In Reply We thank Secades and colleagues for their interest in our case report.1 The diagnosis of left ventricular noncompaction (LVNC) carries with it significant consequences, especially for the competitive athlete of Afro-Caribbean descent.2 We agree that the current diagnostic criteria for LVNC are inadequate. Tizón-Marcos and colleagues3 recently showed that healthy young men demonstrate a variable amount of trabeculation and an incidence of noncompaction cardiomyopathy greater than anticipated when applying the current criteria.
