Hypertrabeculation is a feature of the left ventricle that, by itself, does not coincide with left ventricular non compaction (LVNC), which represents a specific cardiomyopathy. Nowadays, in the absence of gold standard diagnostic criteria, the clinician must integrate imaging aspects together with medical history. The family inheritance for LVNC, presence of neuromuscular disorders, symptoms or signs of heart failure, thromboembolic events, unexplained syncope, pathological findings at rest ECG, Holter ECG, stress test, systolic/diastolic dysfunction at rest echocardiogram, late gadolinium enhancement at cardiac magnetic resonance, and identification of specific mutations are all considered features useful for the diagnosis...

Myocardial non-compaction (NC) is a rare genetic cardiomyopathy commonly believed to develop an intrauterine arrest of endomyocardial morphogenesis. NC is characterized by markedly hypertrabeculations in left ventricle or both ventricles with deep intertrabecular recesses. NC is usually seen isolated, but sometimes other congenital heart abnormalities may accompany to the myocardial NC. In this article we have presented an adult patient with biventricular myocardial NC cardiomyopathy accompanied by severe valvular pulmonary stenosis and patent foramen ovale...

Sudden cardiac death (SCD) is the non-traumatic death, due to loss of heart function that occurs suddenly and unexpectedly within 6 hours of a previously normal state of health. It is related to intense competitive sports promoting ventricular tachycardia (VT)/ventricular fibrillation (VF) in the presence of underlying abnormal substrate. A serial evaluation of cardiac physiologic changes taking place during training will allow the better understanding of athlete's heart and will facilitate its discrimination from other gray-zone cardiomyopathies...

Ventricular myocardial development is a well-orchestrated process involving different cardiac structures, multiple signal pathways, and myriad proteins. Dysregulation of this important developmental event can result in cardiomyopathies, such as left ventricle non-compaction, which affect the pediatric population and the adults. Human and mouse studies have shed light upon the etiology of some cardiomyopathy cases and highlighted the contribution of both genetic and environmental factors. However, the regulation of ventricular myocardial development remains incompletely understood...

To compare image analysis methods for the assessment of left ventricle non-compaction from cardiac magnetic resonance (CMR) imaging. CMR images were analyzed in 20 patients and 10 normal subjects. A reference model of the MR signal was introduced and validated based on image data. Non-compact (NC) myocardium size and distribution were assessed by tracing a single, continuous contour delimiting trabeculated region (Jacquier) or by one-by-one selection of trabeculae (Grothoff). The global non-compact/compact (NC/C) ratio, the NC mass, and the segmental NC/C ratio were assessed...

Left ventricular noncompaction cardiomyopathy (LVNC) is characterized by compact and trabecular layers of the left ventricular myocardium. This cardiomyopathy may occur with congenital heart disease (CHD). Single cases document co-occurrence of LVNC and heterotaxy, but no data exist regarding the prevalence of this association. This study sought to determine whether a non-random association of LVNC and heterotaxy exists by evaluating the prevalence of LVNC in patients with heterotaxy. In a retrospective review of the Indiana Network for Patient Care, we identified 172 patients with heterotaxy (69 male, 103 female)...

PURPOSE: Diagnostic criteria for left ventricular non-compaction (LVNC) are still a matter of dispute. The aim of our present study was to test the diagnostic value of two novel diagnostic cardiac magnetic resonance (CMR) parameters: proof of non-compact (NC) myocardium blood flow using T2 sequences and changes in geometry of the left ventricle. MATERIALS AND METHODS: The study included cases with LVNC and controls, from a data base formed in a period of 3.5 years (n=1890 exams), in which CMR protocol included T2 sequences...

BACKGROUND: There are still ambiguities existing in regard to left ventricular non-compaction (LVNC) diagnostic imaging. The aim of our study was to analyze diagnostic potential of late gadolinium enhancement (LGE) and ventricle geometry in patients with LVNC and controls. METHODS: Data on cardiac magnetic resonance imaging (CMR) studies for LVNC were reassessed from the hospital's database (3.75 years; n=1975 exams). Matching sample of controls included cases with no structural heart disease, hypertrophic or dilative cardiomyopathy, arrhythmogenic right ventricular dysplasia or subacute myocarditis...

Non-compacted left ventricle in adults is a rare occurrence, though it is diagnosed even more rarely. As a rule in patients with non-compacted left ventricle (LVNC) other pathologic condition is diagnosed, notably hypertrophic or dilated cardiomyopathy. The majority of LVNC cases are diagnosed in early infancy but currently there are asymptomatic cases detected by means of echocardiographic examination. Real prevalence of LVNC is unknown. According to many authors LVNC occurs in 9.2-9.5% of children with diagnosed cardiomyopathies...

REVIEW

Non-compaction cardiomyopathy is a heterogeneous and complex entity concerning which there are still many doubts to be resolved. While the American Heart Association includes it among genetic cardiomyopathies, the European Society of Cardiology treats it as an unclassified cardiomyopathy. It may present in a sporadic or familial form, isolated or associated with other heart diseases, affecting only the left ventricle or both and can sometimes appear as a mixed phenotype in patients with other cardiomyopathies...

Contemporary imaging modalities offer noninvasive quantification of myocardial deformation; however, they make gross assumptions about internal structure of the cardiac walls. Our aim is to study the possible impact of the trabeculations on the stroke volume, strain, and capacity of differently sized ventricles. The cardiac left ventricle is represented by an ellipsoid and the trabeculations by a tissue occupying a fixed volume. The ventricular contraction is modeled by scaling the ellipsoid whereupon the measurements of longitudinal strain, end-diastolic, end-systolic, and stroke volumes are derived and compared...

Intense exercise may cause heart remodeling to compensate increases in blood pressure or volume by increasing muscle mass. Cardiac changes do not involve only the left ventricle, but all heart chambers. Physiological cardiac modeling in athletes is associated with normal or enhanced cardiac function, but recent studies have documented decrements in left ventricular function during intense exercise and the release of cardiac markers of necrosis in athlete's blood of uncertain significance. Furthermore, cardiac remodeling may predispose athletes to heart disease and result in electrical remodeling, responsible for arrhythmias...

To differentiate left ventricle non-compaction (LVNC) from hypertrabeculated myocardium due to LV remodeling in β-thalassemia major (β-TM) patients, cardiac magnetic resonance (CMR) images of 38 β-TM patients and 10 LVNC patients were compared using 3 diagnostic criteria: ratio of diastolic segmental non-compacted to compacted myocardium (NC/C ratio) >2.5, percentage of non-compacted LV mass (NC-LVM%) >20% and >25% of global LV mass. Specificity of NC/C ratio of >2.5 was the lowest (58%) and of NC-LVM% of >25% the highest (93%)...

BACKGROUND: Although isolated left ventricular noncompaction (ILVNC) has been described almost two decades ago, our knowledge about its diagnosis, presentation, echocardiographic features and clinical outcome is sparse. We aimed to assess the echocardiographic and clinical characteristics of ILVNC in a group of patients referred to our center. METHODS: Patients who were referred to a tertiary referral center, affiliated with Mashhad University of Medical Sciences, with primary diagnosis of dilated cardiomyopathy underwent comprehensive echocardiographic evaluation...

We performed whole exome sequencing in individuals from a family with autosomal dominant gastropathy resembling Ménétrier disease, a premalignant gastric disorder with epithelial hyperplasia and enhanced EGFR signalling. Ménétrier disease is believed to be an acquired disorder, but its aetiology is unknown. In affected members, we found a missense p.V742G variant in MIB2, a gene regulating NOTCH signalling that has not been previously linked to human diseases. The variant segregated with the disease in the pedigree, affected a highly conserved amino acid residue, and was predicted to be deleterious although it was found with a low frequency in control individuals...

Left ventricle non-compaction (LVNC) has worse outcomes when associated with congenital heart defects (CHD). The co-occurrence and outcomes of LVNC with tricuspid atresia (TA) are not well described. Our study aims to determine the prevalence of LVNC with functionally single ventricle due to TA, and to describe the early outcomes of surgical palliation. A retrospective database search for patients (n = 167,566) and echocardiograms (n = 44,053) was performed in order to collect clinical, echocardiographic, and hemodynamic data of pediatric patients with TA and LVNC at St...

Hypoplastic right heart syndrome is a rare cyanotic congenital heart disease with under-development of the right ventricle, tricuspid, and pulmonary valves leading to right-to-left shunting of the blood through inter-atrial septal defect. Perinatal mortality is high with very few patients surviving to adulthood without corrective surgery. This report describes a 26-year-old young woman, who had recurrent abortions and stillbirths and detected to have marked cyanosis with hypoplastic right heart, sub-arterial ventricular septal defect, absent pulmonary valve, non-compaction of the left ventricle, and bicuspid aortic valve with aortic regurgitation...

INTRODUCTION: isolated left ventricular non-compaction (LVNC) is a heart disease with rather distinct morphologic and clinical manifestations. Available in the literature information about LVNC considering multiple left ventricle abnormal chords (LVAC) as one of its criterion motivated us to review the results obtained in the study of young patients with this pathology. The aim of the research was to demonstrate different clinical variants of left ventricular non-compaction course in adult patients and to clarify some pathogenetic aspects of this pathology...
