Diagnosis of dilation (D) cardiomyopathy (CMP) requires exclusion not only of inflammatory and genetically determined forms but also of some rare diseases. This 51 year old patient with history of moderate arterial hypertension approached a cardiologist because of new onset atrial fibrillation and dyspnea. Echocardiography detected dilation of all cardiac chambers with relatively preserved ejection fraction, causing suspicion of DCMP. Among conditions excluded were coronary atherosclerosis, congenital heart defect with left to right shunt, primary pulmonary hypertension, pulmonary embolism, hypertensive heart, tachycardia induced CMP, arrhythmogenic right ventricular dysplasia, noncompaction myocardium...

BACKGROUND: Barth syndrome (BTHS) is a rare X-linked recessive disease characterized by cardiomyopathy, neutropenia, skeletal myopathy and growth delay. Early diagnosis and appropriate treatment may improve the prognosis of this disease. The purpose of this study is to determine the role of targeted next-generation sequencing (NGS) in the early diagnosis of BTHS in children with cardiomyopathy. METHODS: During the period between 2012 and 2015, a gene panel-based NGS approach was used to search for potentially disease-causing genetic variants in all patients referred to our institution with a clinical diagnosis of primary cardiomyopathy...

A definitively diagnosed case of left ventricular noncompaction (LVNC) has not been previously reported in a non-human species. We describe a Maine Coon cross cat with echocardiographically and pathologically documented LVNC. The cat was from a research colony and was heterozygous for the cardiac myosin binding protein C mutation associated with hypertrophic cardiomyopathy (HCM) in Maine Coon cats (A31P). The cat had had echocardiographic examinations performed every 6 months until 6 years of age at which time the cat died of an unrelated cause...

Noncompaction cardiomyopathy is a rare disorder, often associated with cardiac and noncardiac malformations. Hirschsprung's disease, a well-known aganglionosis, is associated with congenital heart diseases and has been reported to be due to impairment migration and differentiation of neural crest cells. Here, we present an 8-month-old male infant who died for cardiogenic shock after surgical resection of the involved bowel segment. The child was affected by both noncompaction cardiomyopathy and Hirschsprung's disease, two entities which can share a common neural crest-derived etiology...

Left ventricular noncompaction is a rare form of cardiomyopathy, which results from multiple trabeculations in the left ventricular myocardium. The clinical presentation is highly variable, and spectrum includes asymptomatic patients diagnosed during family screening on one end to patients with depressed systolic function, heart failure, thromboembolic complications, and cardiac arrhythmias on the other (Kim et al in J Am Coll Cardiol 53: 2009, 2009). Further, the progression of the condition is highly variable...

Left ventricular hypertrabeculation (LVHT) or noncompaction is a myocardial abnormality of unknown aetiology, frequently associated with monogenic disorders, particularly neuromuscular disorders, or with chromosomal defects. LVHT is diagnosed usually by echocardiography by the presence of a bilayered myocardium consisting of a thick, spongy, noncompacted endocardial layer and a thin, compacted, epicardial layer. The pathogenesis of LVHT is unsolved, and the diagnostic criteria, prognosis, and optimal treatment of patients with LVHT are under debate...

Failure of trabecular myocytes to undergo appropriate cell cycle withdrawal leads to ventricular noncompaction and heart failure. Signaling of growth factor receptor ERBB2 is critical for myocyte proliferation and trabeculation. However, the mechanisms underlying appropriate downregulation of trabecular ERBB2 signaling are little understood. Here, we have found that the endocytic adaptor proteins NUMB and NUMBL were required for downregulation of ERBB2 signaling in maturing trabeculae. Loss of NUMB and NUMBL resulted in a partial block of late endosome formation, resulting in sustained ERBB2 signaling and STAT5 activation...

Noncompaction cardiomyopathy (NCCM) is a unique cardiomyopathy with a diverse array of genotypic and phenotypic manifestations. Its hallmark morphology consists of a bilayered myocardium with a compact epicardial layer and prominent trabeculations that comprise the noncompacted endocardial layer. The controversial diagnostic criteria for NCCM have been frequently discussed in the literature. This review touches on those diagnostic criteria, delves further into the evolving use of advanced imaging techniques within the major imaging modalities (echocardiography, computed tomography, and cardiac magnetic resonance imaging), and proposes an alternative algorithm incorporating these techniques for aiding with the diagnosis of NCCM...

Left ventricular noncompaction cardiomyopathy (LVNC) is a myocardial disorder characterized by prominent and excessive trabeculations with deep recesses in the ventricular wall. Clinical manifestations of LVNC are highly variable, ranging from no symptoms to arrhythmias, heart failure, thromboembolism, or even sudden cardiac death. It is a heterogenetic disease which can be presented as an autosomal, X-linked or mitochondrial disorder. A series of candidate mutations have been identified in LVNC patients or murine models...

BACKGROUND: Cardiac magnetic resonance (CMR) is useful for the diagnosis of left ventricular noncompaction (LVNC). However, there are limited data regarding its prognostic value. OBJECTIVES: The goal of this study was to evaluate the prognostic relevance of CMR findings in patients with LVNC. METHODS: A total of 113 patients with an echocardiographic diagnosis of LVNC underwent CMR at 5 referral centers. CMR diagnostic criterion of LVNC (noncompacted/compacted ratio >2...

BACKGROUND: There is considerable overlap between left ventricular noncompaction (LVNC) and other cardiomyopathies. LVNC has been reported in up to 40% of the general population, raising questions about whether it is a distinct pathological entity, a remodeling epiphenomenon, or merely an anatomical phenotype. OBJECTIVES: The authors determined the prevalence and predictors of LVNC in a healthy population using 4 cardiac magnetic resonance imaging diagnostic criteria...

Isolated left ventricular noncompaction (LVNC) is a rare genetic cardiomyopathy. Clinical manifestations are variable; patients may present with heart failure symptoms, arrhythmias, and systemic thromboembolism. However, it can also be asymptomatic. When asymptomatic, LVNC can manifest later in life after the onset of another unrelated condition. We report a case of LVNC which was diagnosed following a hyperthyroid state secondary to Graves' disease. The association of LVNC with other noncardiac abnormalities including neurological, hematological, and endocrine abnormalities including hypothyroidism has been described in isolated case reports before...

Genetic cardiomyopathies are complex diseases with heterogeneous clinical presentation and phenotypes. Early descriptions of cardiomyopathies originated from case studies involving individuals with severe, paradigmatic presentation, which provided insight into the worst-case scenarios of these conditions. With time, improved diagnostic sensitivity and awareness of cardiomyopathies has uncovered a more heterogeneous disease spectrum, including mild phenotypes overlapping with physiological variation. This diagnostic 'grey area' poses important dilemmas, particularly in athletes...

Isolated ventricular noncompaction (IVNC) is an unclassified cardiomyopathy characterized by prominent intraventricular trabeculations separated by deep intertrabecular recesses. Although microvascular dysfunction is known, myocardial infarction is rare and usually seen as a consequence of coincidental coronary artery disease. We report the case of a 19-year-old male patient who presented to us with symptoms and signs of heart failure. Echocardiography revealed IVNC with severe left ventricular dysfunction...

In this report, we present the case of a patient with biventricular noncompaction cardiomyopathy, Ebstein anomaly, and a left atrial mass who required emergent placement of a left ventricular assist device. The noncompaction cardiomyopathy complicated the left ventricular assist device implantation procedure because the thickened, trabeculated myocardium made it difficult to place the inflow cannula. We discuss our perioperative management strategy, in which transesophageal echocardiography was used, to help the surgical team identify the proper cannula placement and provide a bridge to transplantation...
