Figure 1 : echocardiographic examination of patient A at the age of 37 showing highly trabeculated and mildly dilated left ventricle. In Short axis, in end-systole a non compacted / compacted ratio of 2.4 was calculated; this in addition to a borderline ejection fraction of 52% suggested a diagnosis of left ventricular non compaction. The left ventricular diastolic function was normal. The right ventricle was not dilated and showed normal function. No valvular abnormalities were detected.
