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 #LV #Noncompaction #Echocardiography #Echocardiogram #criteria #Jenni #Chin #cardiology #diagnosis
