Noncompaction cardiomyopathy is characterized by the presence of extensive trabeculations, which could lead to heart failure and malignant arrhythmias. How trabeculations resolve to form compact myocardium is poorly understood. Elucidation of this process is critical to understanding the pathophysiology of noncompaction disease. Here we use genetic lineage tracing to mark the Nppa(+) or Hey2(+) cardiomyocytes as trabecular and compact components of the ventricular wall. We find that Nppa(+) and Hey2(+) cardiomyocytes, respectively, from the endocardial and epicardial zones of the ventricular wall postnatally...

BACKGROUND: Double inlet left ventricle (DILV) is a heterogeneous single ventricle anomaly in which initial presentation, and consequently, timing and palliation mode vary based on morphology and degree of pulmonary or systemic outflow obstruction. Very few reports, mostly old, focused on palliation outcomes of DILV. We report current-era results and examine whether morphologic and subsequently surgical factors influence survival. METHODS: Fifty-eight infants with DILV underwent single ventricle palliation...

Mitochondria plays a key role in providing ATP for the energy-consuming cardiac tissues. Mitochondrial cardiomyopathy is a myocardial condition characterized by abnormal heart structure and/or function secondary to genetic defects involving the mitochondrial respiratory chain. The typical cardiac manifestations of mitochondrial cardiomyopathy include hypertrophic and dilated cardiomyopathy,while left ventricular myocardial noncompaction is less common. Recent research has suggested that most mitochondrial diseases result from mitochondrial DNA mutation,which can be found in genes that encode ancillary proteins needed for genetic transcription (tRNA),in genes that encode subunits of the electron transport chain complexes,or in genes that control the activities of the mitochondria called D-loop zone...

BACKGROUND: Carvajal syndrome is an autosomal dominant or autosomal recessive disorder, manifesting with dilated cardiomyopathy, woolly hair, and palmoplantar keratoma. Additional manifestations can be occasionally found. Carvajal syndrome may be due to mutations in the desmocollin-2, desmoplakin, or plakophilin-2 gene. METHODS AND RESULTS: We report a family with Carvajal syndrome which additionally presented with hypoacusis, noncompaction, recurrent pharyngeal infections, oligodontia, and recurrent diarrhoea...

A 55-year-old man with syncopal episodes was found to have sinus bradycardia at a rate of 37 beats/min, an episode of nonsustained ventricular tachycardia, and left ventricular noncompaction cardiomyopathy. After placement of a dual-chamber cardioverter defibrillator 4 years ago, he has had no further syncopal episodes, and there have been no defibrillator shocks.

BACKGROUND: Noncompaction is a poorly understood form of cardiomyopathy that typically affects the left ventricle and may be associated with congenital heart disease. Right ventricular noncompaction (RVNC) may occur when the left ventricle is affected but is rarely seen in isolation. RVNC may have clinical significance affecting surgical and long-term outcomes. We describe the diagnosis and clinical course in three patients at our institution. METHODS: We performed a retrospective review of patients diagnosed with RVNC over a 12-month period at our institution and reviewed their imaging and clinical course...

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%)...

Left ventricular noncompaction (LVNC) is believed to represent an arrest in the normal process of myocardial compaction, resulting in persistence of both hyper-trabeculation and intra-trabecular recess within the left ventricle. The clinical features of this disease are left ventricular dilatation and systolic dysfunction, which carry a high mortality. Most patients die in infancy, but some cases of LVNC in adults have been reported. To the best of our knowledge, only 4 cases of LVNC with valvular heart disease in adults have recently been operated...

This paper deals with the abstract generalized vector quasi-equilibrium problem in noncompact Hadamard manifolds. We prove the existence of solutions to the abstract generalized vector quasi-equilibrium problem under suitable conditions and provide applications to an abstract vector quasi-equilibrium problem, a generalized scalar equilibrium problem, a scalar equilibrium problem, and a perturbed saddle point problem. Finally, as an application of the existence of solutions to the generalized scalar equilibrium problem, we obtain a weakly mixed variational inequality and two mixed variational inequalities...

A 200∼240 kb SH2B1-containing deletion region on 16p11.2 is associated with early-onset obesity and developmental delay. Here, we describe monozygotic twin brothers with discordant clinical presentations. Intrauterine fetal growth restriction was present in both twins. Additionally, twin A exhibited coarctation of aorta, left ventricular noncompaction, atrial septal defect, pericardial effusion, left hydronephrosis, and moderate developmental delay, whereas twin B exhibited single umbilical artery. Chromosome microarray analysis was performed on both twins and their parents...

Trap-assisted recombination, despite being lower as compared with traditional inorganic solar cells, is still the dominant recombination mechanism in perovskite solar cells (PSCs) and limits their efficiency. We investigate the attributes of the primary trap-assisted recombination channels (grain boundaries and interfaces) and their correlation to defect ions in PSCs. We achieve this by using a validated device model to fit the simulations to the experimental data of efficient vacuum-deposited p-i-n and n-i-p CH3NH3PbI3 solar cells, including the light intensity dependence of the open-circuit voltage and fill factor...

Ventricular noncompaction cardiomyopathy is a rare form of congenital cardiomyopathy with increasing evidence of genetic etiology, especially when presenting in childhood. Fetal presentation is rare. We describe a case of fetal hydrops, presenting at 24 weeks gestation and leading to intrapartum death at 26 weeks gestation. Autopsy examination revealed characteristic features of left ventricular noncompaction. A genetic analysis identified a constellation of variants of unknown significance in MYH6, TNNC1, and MYBPC3, genes known to be important in sarcomeric function...
