Table 1 Echocardiographic Criteria for the Diagnosis of NVM

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
