The current echocardiographic diagnostic criteria for noncompaction cardiomyopathy (NCC) have variable sensitivity and low specificity. Moreover, there are limited data on the use of myocardial deformation imaging for early detection of myocardial dysfunction in children with NCC. We describe left ventricular (LV) deformation patterns in children with NCC, with the goal of identifying a potential diagnostic pattern. We prospectively enrolled 30 children with NCC (47% male; mean age 7.2 years) and 30 age- and gender-matched controls...

Ventricular trabeculation and compaction are two essential morphogenetic events for generating a functionally competent ventricular wall. A significant reduction in trabeculation is usually associated with hypoplastic wall and ventricular compact zone deficiencies, which commonly leads to embryonic heart failure and early embryonic lethality. In contrast, the arrest of ventricular wall compaction (noncompaction) is believed to be causative to the left ventricular noncompaction (LVNC), a genetically heterogeneous disorder and the third most common cardiomyopathy among pediatric patients...

Left ventricular noncompaction (LVNC) is a multifactorial structural abnormality of the myocardial wall characterized by prominent trabeculae and deep trabecular recesses. LVNC may present as a congenital or acquired defect characterized by 2 distinct tissue layers: a spongy, noncompacted inner myocardium and a thin, compacted outer myocardium. Patients with LVNC are prone to thromboembolic events, either due to deep trabeculations in the noncompacted myocardium or due to arrhythmias accompanying the defect...

BACKGROUND: Current diagnostic criteria for noncompaction cardiomyopathy (NCC) lack specificity, and the disease lacks prognostic indicators. Reverse apical rotation (RAR) with abnormal rotation of the cardiac apex in the same clockwise direction as the base has been described in adults with NCC. The aim of this study was to test the hypothesis that RAR might differentiate between symptomatic NCC and benign hypertrabeculations and might be associated with ventricular dysfunction. METHODS: Echocardiograms from 28 children with NCC without cardiac malformations were prospectively compared with those from 29 age-matched normal control subjects...

The high spatial resolution of cardiac computed tomography (CT) and cardiac magnetic resonance (CMR) permit the diagnosis of congenital ventricular outpouchings (CVOs), including congenital ventricular diverticula (CVD), congenital ventricular aneurysms (CVA), clefts, and crypts. A unique classification has not been established, and these terms are used interchangeably with confounding terminology. Moreover, their significance is not univocal. A research was performed using PubMed on six subjects: (1) congenital left ventricular outpouchings; (2) congenital ventricular diverticulum; (3) congenital ventricular aneurysm; (4) ventricular clefts; (5) ventricular crypts; and (6) ventricular crevices...

BACKGROUND: The prognosis of patients with left ventricular hypertrabeculation/noncompaction (LVHT) and its association with neuromuscular disorders (NMDs) is a controversial topic. The aim of this study was to assess whether the prognosis of LVHT patients is dependent on cardiac phenotype and the presence of NMDs. METHODS: Consecutive patients who were diagnosed with LVHT between 1995 and 2016 were included in the study. Cardiac phenotype was classified according to the recommendations of the European Society of Cardiology as: "dilated" if the left ventricular end-diastolic diameter (LVEDD) was >57 mm and left ventricular fractional shortening (FS) was ≤25%; "hypertrophic" if LVEDD was ≤57 mm, FS > 25%, and left ventricular posterior wall (LVPWT) and interventricular septal thickness (IVST) were both >13 mm; "intermediate" if LVEDD was >57 mm and FS > 25% or if LVEDD was ≤57 mm and FS ≤ 25%; and "normal" if LVEDD was ≤57 mm, FS > 25%, and IVST and LVPWT ≤ 13 mm...

Sudden cardiac death in young adults may be associated with rare cardiomyopathies such as left ventricular noncompaction (LVNC) and arrhythmogenic right ventricular (ARVC) cardiomyopathies. LVNC is characterised by hypertrabeculations and deep recesses of the left ventricle. ARVC presents with thin myocardium as a result of extensive fibro-fatty infiltrations. In both conditions, death may be due to arrhythmia, thromboembolic events or heart failure. We report a case of a 21-year old athletic young man who collapsed at the futsal court right after the game...

PURPOSE: This study examined electrophysiological characteristics and outcomes of patients with sustained ventricular tachycardia (VT) in the setting of isolated ventricular noncompaction (IVNC). BACKGROUND: In patients with IVNC, VT has been associated with sudden cardiac death. However, the electrophysiological characteristics and optimal management of these VTs are only incompletely understood. METHODS: This retrospective cohort study assessed arrhythmia characteristics and outcomes in IVNC patients with sustained monomorphic VTs...

BACKGROUND: Left ventricular noncompaction (LVNC) is associated with progressive LV systolic dysfunction and dilated cardiomyopathy. We aimed to investigate the echocardiographic and clinical characteristics associated with LV ejection fraction (LVEF) and moderate or greater systolic dysfunction in patients with LVNC. METHODS: Our institutional echocardiography database was retrospectively reviewed between 2008 and 2014, and 62 patients with LVNC were identified...

Left ventricular noncompaction (LVNC) is an inherited cardiomyopathy involving numerous genes. To identify novel candidate causal mutations, a whole exome sequencing study was performed on a Chinese LVNC family. Exons of the most prevalent pathogenic genes of LVNC (myosin heavy chain 7 and actin, α‑cardiac muscle 1) were sequenced, although no mutations were identified. Following this, Burrows‑Wheeler Aligner, PICARD and Genome Analysis Toolkit (v.2.8) were used to analyze the exome sequencing data. Non‑silent single nucleotide variants (SNVs) that were identified in patients with LVNC, although not in the healthy individual, were investigated further using SNV prioritization via the integration of genomic data (SPRING) based on P‑values...

To our knowledge, left ventricular noncompaction (LVNC) and hypertrophic cardiomyopathy (HCM) commonly occur as separate disorders in different patients; however, LVNC associated with HCM, which is called hypertrophic LVNC, is relatively rare.1) Here we report two sporadic cases of hypertrophic LVNC which were diagnosed by echocardiography and cardiac magnetic resonance (CMR).

This report describes a 66-year-old Caucasian male who acutely developed severe, bilateral impairment of visual acuity at 24 years of age. Leber's hereditary optic neuropathy (LHON) was suspected but the diagnosis was not genetically confirmed until the age of 49 years when the primary LHON mutation m.3460G>A was detected. Since onset, visual acuity had slightly improved. The family history was positive for LHON (brother, two sisters of mother, female cousin) and genetically confirmed in his brother and one aunt...

Left ventricular noncompaction (LVNC) is a unique inherited cardiomyopathy, characterized by an increased risk of adverse cardiovascular events such as heart failure, arrhythmia or sudden cardiac death. Although in comparison to dilated cardiomyopathy, the number of clinical studies concerning LVNC is still small, it is quickly increasing, which reflects a huge effort of the cardiovascular society to develop data to improve understanding of this cardiomyopathy. However, the predictors of adverse outcomes in LVNC are not well established...

Transplantation for adult patients with congenital heart disease (ACHD) is a growing clinical endeavor in the transplant community. Understanding the results and defining potential high-risk patient subsets will allow optimization of patient outcomes. This review summarizes the scope of ACHD transplantation, the mechanisms of late ventricular dysfunction, the ACHD population at risk of developing heart failure, the indications and potential contraindications for transplant, surgical considerations, and post-transplant outcomes...

OBJECTIVES: Incidence of sickle cell disease (SCD) in Ireland has dramatically increased. Disease survival has also steadily improved however cardiovascular manifestations remain important causes of morbidity. These include reports of left ventricular hypertrabeculation (LVHT)/noncompaction. We sought to investigate the prevalence of LVHT among a large cohort of children with SCD. METHODS: We retrospectively reviewed the records of all patients with a diagnosis of SCD who had undergone surveillance echocardiography at Our Lady's Children's Hospital Crumlin (OLCHC) from 1998 to 2015...
