Isolated ventricular noncompaction (IVNC): a case report

Isolated ventricular noncompaction, also known as left ventricular noncompaction (LVNC), isolated noncompaction of the ventricular myocardium (INVM), noncompaction of the left ventricular myocardium (INLVM), left ventricular hypertrabeculation, and spongy myocardium, is a rare and recently described cardiomyo-pathy with characteristic gross morphological abnormalities. It can present in paediatric and adult patients. Currently, the diagnosis can be made by echocardiography or magnetic resonance imaging (MRI). To the best of our knowledge, so far, there is no histo-pathology description of this entity in the English literature. Although aetiology, pathogenesis and histopathological features of IVNC are not clear, there is evidence for genetic basis in at least some cases, with subsequent implication of genetic counselling for family members of the patients. Here, we report a case of isolated ventricular noncompaction cardiomyopathy, and discuss its clinical, imaging and histopathology features.
