BACKGROUND: Hypoplastic left heart syndrome (HLHS) covers a spectrum of rare congenital anomalies characterised by a non-apex forming left ventricle and stenosis/atresia of the mitral and aortic valves. Despite many studies, the causes of HLHS remain unclear and there are conflicting views regarding the role of flow, valvar or myocardial abnormalities in its pathogenesis, all of which were proposed prior to the description of the second heart field. Our aim was to re-evaluate the patterns of malformation in HLHS in relation to recognised cardiac progenitor populations, with a view to providing aetiologically useful sub-groupings for genomic studies...

Hypoplastic Left Heart Syndrome (HLHS) is one of the most challenging congenital heart defects which require surgical interventions during neonatal period. In normal risk cohort, its surgical outcome has been improved dramatically since Dr. William Norwood reported the 1st successful case more than 30 years ago. The introduction of routine bilateral pulmonary artery banding with subsequent Norwood operation during early infantile( we call it as "rapid 2 stage Norwood operation") has brought an earlier hemodynamic stabilization after Norwood operation...

Despite the common occurrence of thrombosis in Fontan circulations, the mid-term thrombotic risk beyond the first two postoperative years is poorly defined especially in total cavo pulmonary Fontan. This study examines the thrombotic incidence and risk beyond the first 2 years after contemporary Fontan surgery. Using a retrospective cohort study design, 89 Fontan patients, 50 male, were included and evaluated with a median of 8.3 years (IQR 6.8-11.4) follow-up. Hospital records were reviewed for known risk factors of thrombosis, thrombotic events, antiplatelet and anticoagulation management, and basic characteristics...

Holt-Oram syndrome is an autosomal dominant disorder, characterised by skeletal abnormalities of the upper limb associated with congenital heart defect, mainly atrial and ventricular septal defects. Skeletal defects exclusively affect the upper limbs in the preaxial radial ray distribution and are bilateral and asymmetrical. They range from clinodactyly, absent or digitalised thumb, hypoplastic or absent radii, and first metacarpal to hypoplastic ulna and carpal bone anomalies. Cardiac involvement ranges from asymptomatic conduction disturbances to multiple structural defects...

Matthew Lewis, Marlon Rosenbaum
PURPOSE OF REVIEW: Hypoplastic left heart syndrome (HLHS) is characterized by underdevelopment of the mitral valve, left ventricle, and aorta and is ultimately palliated with a single-ventricle repair. Universally fatal in infancy prior to the advent of modern surgical techniques, the majority of HLHS patients will now reach adulthood. However, despite improvements in early survival, the HLHS population continues to face significant morbidity and early mortality. This review delineates common sources of patient morbidity and highlights areas in need of additional research for this growing segment of the adult congenital heart disease population...

Intrauterine growth restriction in animal models reduces heart size and cardiomyocyte number at birth. Such incomplete cardiomyocyte endowment is believed to increase susceptibility toward cardiovascular disease in adulthood, a phenomenon referred to as developmental programming. We have previously described a mouse model of impaired myocardial development leading to a 25% reduction of cardiomyocyte number in neonates. This study investigated the response of these hypoplastic hearts to pressure overload in adulthood, applied by abdominal aortic constriction (AAC)...

INTRODUCTION: There is relatively sparse literature on the use of administrative datasets for research in patients with adult congenital heart disease (ACHD). The goal of this analysis is to examine the accuracy of administrative data for identifying patients with ACHD who died. METHODS: A list of the International Classification of Diseases codes representing ACHD of moderate- or great-complexity was created. A search for these codes in the electronic health record of adults who received care in 2010-2016 was performed, and used state death records to identify patients who died during this period...

OBJECTIVES: Adrenergic receptor (ADR) genotypes have been associated with adverse outcomes in heart failure. Our objective was to evaluate the association of ADR genotypes with post-Norwood outcomes in infants with hypoplastic left heart syndrome (HLHS). METHODS: Infants with HLHS participating in the Pediatric Heart Network Single-Ventricle Reconstruction Trial underwent genotyping for 4 single-nucleotide polymorphisms in 3 ADR genes: ADRB1_231A/G, ADRB1_1165G/C, ADRB2_5318C/G, and ADRA2A_2790C/T...

Coordinated cardiomyocyte growth, differentiation, and morphogenesis are essential for heart formation. We demonstrate that the bHLH transcription factors Hand1 and Hand2 play critical regulatory roles for left ventricle (LV) cardiomyocyte proliferation and morphogenesis. Using an LV-specific Cre allele (Hand1LV-Cre), we ablate Hand1-lineage cardiomyocytes, revealing that DTA-mediated cardiomyocyte death results in a hypoplastic LV by E10.5. Once Hand1-linage cells are removed from the LV, and Hand1 expression is switched off, embryonic hearts recover by E16...

INTRODUCTION AND OBJECTIVES: Congenital heart disease is a major cause of infant mortality in developed countries. In Spain, there are no publications at national level on mortality due to congenital heart disease. The aim of this study is to analyse mortality in infants with congenital heart disease, lethality of different types of congenital heart disease, and their variation over a ten-year period. METHODS: A retrospective observational study was performed to evaluate mortality rate of children under one year old with congenital heart disease, using the minimum basic data set, from 2003 to 2012...

The paraventricular nucleus of hypothalamus plays important roles in the regulation of energy balance and fetal growth. However, the molecular mechanisms underlying its formation and function have not been clearly elucidated. Various mutations in the human COUP-TFII gene, which encodes a nuclear receptor, result in growth retardation, congenital diaphragmatic hernia and congenital heart defects. Here, we show that COUP-TFII gene is expressed in the developing hypothalamus in mouse. The ventral forebrain-specific RXCre/+; COUP-TFII (F/F) mutant mice display growth retardation...

Hypoplastic left heart syndrome is a complex congenital heart disease characterised by the underdevelopment of the left ventricle normally treated with a three-stage surgical repair. In this study, a multiscale closed-loop cardio-circulatory model is created to reproduce the pre-operative condition of a patient suffering from such pathology and virtual surgery is performed. Firstly, cardio-circulatory parameters are estimated using a fully closed-loop cardio-circulatory lumped parameter model. Secondly, a 3D standalone FEA model is build up to obtain active and passive ventricular characteristics and unloaded reference state...

We hypothesized that fetuses with hypoplastic left heart syndrome (HLHS) have impaired growth compared to expected growth for gestational age. This is a retrospective cohort study including singleton fetuses with isolated HLHS identified from a single, referral center's ultrasound database. To account for variable timing of ultrasounds, z-scores for gestational age were assigned for each biometric parameter. We identified 169 fetuses, of which 96 had more than one ultrasound. The median number of ultrasound evaluations per fetus was 2 (range 1-5)...

Background -In infants requiring three-stage single ventricle palliation for hypoplastic left heart syndrome, attrition after the Norwood procedure remains significant. The effect of the timing of stage-2-palliation (S2P), a physician-modifiable factor, on long term survival is not well understood. We hypothesized that an optimal interval between the Norwood and S2P that both minimizes pre-S2P attrition and maximizes post-S2P survival exists and is associated with individual patient characteristics. Methods -The NIH/NHLBI Pediatric Heart Network Single Ventricle Reconstruction Trial public dataset was used...
