[Left ventricular hypertrabeculation or noncompaction: are new diagnostic criteria required?].

not be established. The early and late phases of gadolinium enhancement (Figure 3) were normal. In 68% of all post mortems and in recent studies using CMR, limited areas of noncompacted myocardium have been found in normal hearts and in patients with heart diseases, such as HCM, dilated cardiomyopathy (DCM), and even hypertensive cardiomyopathy. Of note in this case was the considerable diagnostic value of the medical history (paternal background) and the ECG, which led us to suspect a partial phenotypic expression of NCC, considering the great variation in the manifestations of sarcomere mutations. Defects in the MYH7 gene are of particular interest here, being implicated in the family history of HCM and DCM and recently, in NCC.
