Mitochondrial Abnormalities at Autopsy of Fetal Noncompaction

In a recent article, Tian et al. [1] reported about the echocardiographic and pathological findings in 9 fetuses with left ventricular hyper trabeculation/non-compaction (LVHT). We have the following comments and concerns. The authors differentiate between non-compaction cardiomyopathy (NCCM) and left ventricular non-compaction (LVNC). In our view these are two different terms which describe the same entity. Which is the difference between NCCM and LVNC in the authors’ view? Absence of additional cardiac abnormalities should not be a differentiating criterion.
