Isolated left ventricular noncompaction is a primary, genetic cardiomyopathy thought to be caused by arrest of normal embryogenesis of endocardium and myocardium, characterised by a pattern of excessively prominent trabecular meshwork and deep intertrabecular recesses with to-and-from flow in continuity with the ventricular flow and the absence of other structural heart diseases. Isolated noncompaction of the ventricular myocardium is considered to predominantly affect the left ventricle. Our earlier observations suggest that both ventricles may be involved. We present another case of isolated noncompaction of both ventricles.

Left ventricular non-compaction (LVNC) is a rare primary cardiomyopathy with genetic etiology, resulting from an abnormality of myocardial development during embryogenesis. It carries an elevated risk of left ventricular dysfunction, thromboembolic events and malignant arrhythmias. We report the case of LVNC associated with paroxysmal atrial fibrillation and ankyrin 2 () mutation at the genetic test.

Left ventricular hypertrabeculation (LVHT) used to be a rare phenotypic trait. With advances in diagnostic imaging techniques, LVHT is being recognised in an increasing number of people. The scientific data show the possibility of the overdiagnosis of this cardiomyopathy in a population of people who have very high levels of physical activity.

Background: Myocardial disease is an important component of the wide field of cardiovascular disease. However, the phenomenon of multiple myocardial diseases in a single patient remains understudied.
Aim: To investigate the prevalence and impact of myocarditis in patients with genetic cardiomyopathies and to evaluate the outcomes of myocarditis treatment in the context of cardiomyopathies.

End-stage heart failure due to left ventricular noncompaction (LVNC) poses unique challenges for ventricular assist device implantation, like inflow cannula obstruction due to trabeculations. We report a case of an 11-year-old boy with LVNC who underwent successful HeartWare implantation as a bridge to transplant for high pulmonary vascular resistance and had successful heart transplantation after 4 years of HeartWare support.

This study aims to develop a nomogram prediction model for assessing the cardiogenic composite endpoint, which includes intracardiac thrombosis (ICT) combined with heart failure (HF) in patients with non-compaction cardiomyopathy (NCM) patients. We retrospectively analyzed clinical data from NCM patients (January 2018 to May 2024), who were randomly assigned to training and validation cohorts. Independent predictors were identified using logistic regression, and a nomogram model was developed.
