From: Echocardiography in the diagnosis left ventricular noncompaction

Chin Criteria (1990)

Jennni Criteria (1999)

Absence of any other coexisting cardiac structural abnormality

Absence of any other coexisting cardiac structural abnormality

Numerous, excessively prominent trabeculations and deep intertrabecular recesses

Numerous, excessively prominent trabeculations and deep intertrabecular recesses

Views: parasternal long axis, subxyphoid, and apical

Views: parasternal short axis, and apical

Focus on depth of recesses

Focus on a 2-layer structure

Measured in end-diastole

Measured in end-systole

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

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