Gradual regression of myocardial sinusoids normally occurs between weeks 5 to 8 of embryonic life, when the ventricular myocardium undergoes gradual compaction mediated by tissue-specific growth factors (3).
Pressure overload or myocardial ischemia in these secondary cases of myocardial noncompaction may prevent the normal regression of embryonic myocardial sinusoids. However, currently it is unclear whether the isolated and secondary forms of noncompaction are common or distinct lesions.
