Echocardiographic criteria |
|
|
Chin et al. [11] |
1. Prominent trabeculations, deep recesses |
2. LV free-wall thickness (ED) augmentation from base to apex |
3. Gradual reduction in the X:Y ratio of myocardial thickness from the mitral valve level to the papillary muscle level (PSAX and apical views) |
X – from the epicardial surface to the bottom of the trabeculations |
Y – from the epicardial surface to the top of the trabeculations |
|
Stöllberger and Finsterer [12] |
1. Two-layered myocardium with the non-compacted layer thicker than the compacted myocardial layer (ED) |
2. >3 trabeculations bulging from the LV apical wall to the papillary muscle |
3. Intertrabecular spaces perfused |
|
Jenni et al. [13] |
1. Bilayered myocardium, multiple prominent trabeculations (ES) |
2. Non-compacted to compacted ratio >2:1 |
3. LV cavity communication with the intertrabecular spaces demonstrated by color Doppler |
4. No coexisting cardiac abnormalities |
|
MRI criteria |
|
Petersen et al. [14] |
Non-compacted to compacted ratio >2.3 (ED) |
|
Jacquier et al. [15] |
LV trabecular mass >20% of the global mass |
