Fig. 3From: Overlap phenotypes of the left ventricular noncompaction and hypertrophic cardiomyopathy with complex arrhythmias and heart failure induced by the novel truncated DSC2 mutationEchocardiographic characteristics of the proband II: 1. A To quantify the extent of noncompaction at the site of maximal wall thickness. The end-systolic ratio of noncompacted to compacted thickness was determined. The two layers were best visualized at end-systole as shown in this long-axis view (N, non-compacted layer; C, compacted layer). B, C Color Doppler study showed typical forward blood flow from the ventricular cavity into the deep spaces between the prominent trabeculations during diastole (in B represented by a red signal). Mild regurgitation could be seen in the mitral and tricuspid valves (C)Back to article page
