Zusammenfassung: | Introduction. Left ventricular noncompaction (LVNC) is a congenital disorder characterised by prominent trabeculations in the left ventricular myocardium. This heart condition very often goes completely undetected, or is mistaken for hypertrophic cardiomyopathy or coronary disease. Case report. A middle-aged female with a positive family history of coronary disease was admitted with chest pain, electrocardiography (ECG) changes in the area of the inferolateral wall and elevation in cardiac specific enzymes. Initially, she was suspected of having acute coronary syndrome. However, in the left ventricular apex, especially alongside the lateral and inferior walls, cardiac ultrasound visualised hypertrabeculation with multiple trabeculae projecting inside the left ventricular cavity. A short-axis view of the heart above the papillary muscles revealed the presence of two layers of the myocardium: a compacted homogeneous layer adjacent to the epicardium and a spongy layer with trabeculae and sinusoids under the endocardium. The thickness ratio between the two layers was 2.2:1. The same abnormalities were corroborated by multislice computed tomography (MSCT) of the heart. Conclusion. Left ventricular noncompaction is a rare, usually hereditary cardiomyopathy, which should be considered as a possibility in patients with myocardial hypertrophy. It is very often mistaken for coronary disease owing to ECG changes and elevated cardiac specific enzymes associated with myocardial hypertrophy and heart failure.
