Description
(i) Prominent trabeculations with deep recesses (ii) Decrease in ratio from MV level to papillary muscle level of the distance from the epicardium to the trough of the trabeculations () to the epicardium to the peak of the trabeculations () (iii) Increasing LV wall thickness from base to apex
(i) Bilayered myocardium with multiple, prominent trabeculations in end-systole (ii) NC/C ratio of >2 : 1 (iii) Communication with the intertrabecular space demonstrated with color Doppler (iv) Absence of coexisting cardiac abnormalities
(i) Two-layer myocardium in which the noncompacted layer is thicker than the compacted myocardium (ii) >3 prominent trabeculations protruding from the LV wall apical to the papillary muscles (iii) Perfused intertrabecular spaces
