Echocardiographic criteria of LV Non-compaction

Chin Criteria (1990):

 • Absence of any other coexisting cardiac structural abnormality

 • Numerous, excessively prominent trabeculations and deep intertrabecular recesses

 • Views: parasternal long axis, subxyphoid, and apical

 • Focus on depth of recesses

 • Measured in end-diastole

 • Ratio of distance from the epicardial surface to the trough of the trabecular recesses and distance from the epicardial surface to peak of trabeculation ≤ 0.5

Jenni Criteria (1999):

 • Absence of any other coexisting cardiac structural abnormality

 • Numerous, excessively prominent trabeculations and deep intertrabecular recesses

 • Views: parasternal short axis and apical

 • Focus on a 2-layer structure

 • Measured in end-systole

 • Ratio of thick noncompacted layer to thin compacted ≥ 2,  Perfused intertrabecular recesses suplied by intraventricular blood on color Doppler analysis
