Left ventricular non-compaction cardiomyopathy: outlook and cardiac arrhythmias

Cardiomyopathies are an important and diverse group of myocardial diseases associated with mechanical, electrical, or both dysfunctions. The left ventricular (LV) non-compaction is a familial cardiomyopathy of uncertain etiology, whose exact incidence and prevalence are unknown. It is characterized by an increase in the trabecular mass of the LV in contrast to a thin compact epicardial layer that can be visualized with imaging techniques that confirm the diagnosis. In this article is described the classification of MOGE (S) for cardiomyopathies, electrocardiographic disorders that can be found in patients with left ventricular non-compaction, the role of programmed electrical stimulation of the heart and other aspects of interest of this disease. In addition, some demonstrative electrocardiographic disorders (Stollberger and Jenni criteria) found in affected patients are presented.
