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.
