Trends in survival of children with severe congenital heart defects by gestational age at birth: A population-based study using administrative hospital data for England. Paediatr Perinat Epidemiol 2023; 37:390-400. [PMID: 36744612 PMCID: PMC10946523 DOI: 10.1111/ppe.12959] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/13/2022] [Revised: 01/09/2023] [Accepted: 01/22/2023] [Indexed: 02/07/2023]
Abstract
BACKGROUND Children with congenital heart defects (CHD) are twice as likely as their peers to be born preterm (<37 weeks' gestation), yet descriptions of recent trends in long-term survival by gestational age at birth (GA) are lacking. OBJECTIVES To quantify changes in survival to age 5 years of children in England with severe CHD by GA. METHODS We estimated changes in survival to age five of children with severe CHD and all other children born in England between April 2004 and March 2016, overall and by GA-group using linked hospital and mortality records. RESULTS Of 5,953,598 livebirths, 5.7% (339,080 of 5,953,598) were born preterm, 0.35% (20,648 of 5,953,598) died before age five and 3.6 per 1000 (21,291 of 5,953,598) had severe CHD. Adjusting for GA, under-five mortality rates fell at a similar rate between 2004-2008 and 2012-2016 for children with severe CHD (adjusted hazard ratio [HR] 0.79, 95% CI 0.71, 0.88) and all other children (HR 0.78, 95% CI 0.76, 0.81). For children with severe CHD, overall survival to age five increased from 87.5% (95% CI 86.6, 88.4) in 2004-2008 to 89.6% (95% CI 88.9, 90.3) in 2012-2016. There was strong evidence for better survival in the ≥39-week group (90.2%, 95% CI 89.1, 91.2 to 93%, 95% CI 92.4, 93.9), weaker evidence at 24-31 and 37-38 weeks and no evidence at 32-36 weeks. We estimate that 51 deaths (95% CI 24, 77) per year in children with severe CHD were averted in 2012-2016 compared to what would have been the case had 2004-2008 mortality rates persisted. CONCLUSIONS Nine out of 10 children with severe CHD in 2012-2016 survived to age five. The small improvement in survival over the study period was driven by increased survival in term children. Most children with severe CHD are reaching school age and may require additional support by schools and healthcare services.

Abstract
OBJECTIVE Surgical outcome data differs from overall outcomes of prenatally diagnosed fetuses with hypoplastic left heart syndrome (HLHS). Our aim was to describe outcome of prenatally diagnosed fetuses with this anomaly. METHODS Retrospective review of prenatally diagnosed classical HLHS at a tertiary hospital over a 13-year period, estimated due dates 01/08/2006 to 31/12/2019. HLHS-variants and ventricular disproportion were excluded. RESULTS 203 fetuses were identified with outcome information available for 201. There were extra-cardiac abnormalities in 8% (16/203), with genetic variants in 14% of those tested (17/122). There were 55 (27%) terminations of pregnancy, 5 (2%) intrauterine deaths and 10 (5%) babies had prenatally planned compassionate care. There was intention to treat (ITT) in the remaining 131/201(65%). Of these, there were 8 neonatal deaths before intervention, two patients had surgery in other centers. Of the other 121 patients, Norwood procedure performed in 113 (93%), initial hybrid in 7 (6%), and 1 had palliative coarctation stenting. Survival for the ITT group from birth at 6-months, 1-year and 5-years was 70%, 65%, 62% respectively. Altogether of the initial 201 prenatally diagnosed fetuses, 80 patients (40%) are currently alive. A restrictive atrial septum (RAS) is an important sub-category associated with death, HR 2.61, 95%CI 1.34-5.05, p = 0.005, with only 5/29 patients still alive. CONCLUSION Medium-term outcomes of prenatally diagnosed HLHS have improved however it should be noted that almost 40% do not get to surgical palliation, which is vital to those doing fetal counselling. There remains significant mortality particularly in fetuses with in-utero diagnosed RAS.

Abstract
No area of congenital heart disease has undergone greater change and innovation than Single Ventricle management over the past 20 years. Surgical and catheter lab interventions have transformed outcomes such that in some subgroups more than 80% of these patients can survive into adulthood. Driven by parallel development in diagnostic imaging and cardiac intensive care, surgical management is focused on the neonatal period as the key time to creating a balanced circulation and limiting pulmonary blood-flow. Different configurations of the circulation including new types of surgical shunts and the role of 'hybrid' circulations provide greater options and better physiology. This overview will focus on these changes in surgical management and timing but also look at the exciting areas of regenerative therapies to improve ventricular function, and the concept of ventricular rehabilitation to achieve biventricular circulations in certain groups of patients. The importance of early (neonatal) intervention and multidisciplinary approach to management is emphasised, as well as looking beyond simply survival but also improving neurodevelopmental outcomes.

Abstract
The aim of foetal cardiac therapy is to treat an abnormality at the developmental stage so that the process of cardiac growth, which is complex and relies on the volume and direction of circulating blood as well as genetic determinants, can continue. In reality, most cardiac interventions are palliative; hence, major abnormalities are still present at birth. Nevertheless, tangible benefits following successful foetal intervention include improved haemodynamics and reduction in secondary damage leading to better postnatal outcomes. In cases of semilunar valve stenosis, or atresia, foetal valvuloplasty aims to achieve a biventricular, rather than univentricular, circulation. Opening and stenting a restrictive atrial foramen may preserve the pulmonary function in cases of hypoplastic left heart syndrome, thereby increasing the chances of successful postnatal surgery. More recent endeavours include percutaneous implantation of a miniaturised pacemaker to treat complete heart block and the promotion of left-sided heart growth by chronic maternal hyperoxygenation. The true clinical benefit of these interventions over natural history remains uncertain because of the paucity of appropriate randomised controlled trials (RCTs). Foetal cardiac therapy must now move from a pioneering approach to one that is supported by evidence, as has been done successfully for other foetal therapies.

Abstract
Hypoplastic left heart syndrome (HLHS) was a uniformly fatal diagnosis before 1983, when surgical treatment was first undertaken with the Norwood I operation as the first of 3-staged operations. Since then, operative survival rate of stage I has risen from 53% to over 90% in the current era, not only thanks to technical advances in surgery but also through prenatal diagnosis and imaging, enhanced cardiopulmonary bypass technology, better perioperative intensive care, and closer interstage monitoring. The improvements in patient outcomes achieved through rigorous multidisciplinary teamwork have come at a tremendous cost in manpower and resources, making HLHS still a challenge to all congenital heart programs, established or emerging. We review the various surgical steps to treat HLHS and their current expected outcomes, and put into perspective cost considerations compared to other more “simple” congenital heart defects.

Abstract
BACKGROUND There is no consensus on the effectiveness of prenatal diagnosis except for hospitalized outcomes. Hence, a meta-analysis of published literature was conducted to assess the effect of prenatal diagnosis. METHODS Literature review has identified relevant studies up to December 2013. A meta-analysis was performed according to the guidelines from the Cochrane review group and the PRISMA statement. Studies were identified by searching PubMed, Embase, the Cochrane Central Register of Controlled Trials and World Health Orgnization clinical trials registry center. Meta-analysis was performed in a fixed/random-effect model using Revman 5.1.1 according to the guidelines from the Cochrane review group and the PRISMA guidelines. RESULTS The results from 13 cohort studies in 12 articles were analyzed to determine the optimal treatment with the lower rate of perioperative mortality in prenatal diagnosis. The superiority of a prenatal diagnosis has been proven because the surgical procedure could be done in the early neonatal period (95% CI, -0.76, -0.40). The prenatal diagnosis has also remarkably reduced the preoperative and postoperative mortality rates in cases of transposition of the great arteries (95% CI=0.06, 0.80; 95% CI=0.01, 0.82, respectively), as well as the overall results with all subtypes (95% CI=0.18, 0.94; 95% CI=0.46, 0.94, respectively). CONCLUSIONS Prenatal diagnosis is effective in perinatal management with an earlier intervention for major congenital heart disease, but only results in a reduced perioperative mortality in cases of transposition of the great arteries. Further investigations are required to evaluate the effect of prenatal diagnosis on life quality during a long-term follow-up.

Abstract
OBJECTIVE To determine if prenatal diagnosis improves the chance that a newborn with critical congenital heart disease will survive to undergo planned cardiac surgery. METHODS A systematic review of the medical literature identified eight studies which met the following criteria: compared outcomes between newborns with prenatal and those with postnatal diagnosis of critical congenital heart disease; compared groups of patients with the same anatomical diagnosis; provided detailed information on cardiac anatomy; included detailed information on preoperative cause of death. A meta-analysis was performed to assess differences in preoperative mortality rates between newborns with prenatal diagnosis and those with postnatal diagnosis. Patients with established risk factors for increased mortality (high risk) and those whose families chose comfort care rather than cardiac surgery were excluded. RESULTS In patients with comparable anatomy, standard risk, a parental desire to treat and optimal care, newborns with a prenatal diagnosis of critical congenital heart disease were significantly less likely to die prior to planned cardiac surgery than were those with a comparable postnatal diagnosis (pooled odds ratio, 0.26; 95% CI, 0.08-0.84). CONCLUSIONS For newborns most likely to benefit from treatment for their critical congenital heart disease, because they did not have additional risk factors and their families pursued treatment, prenatal diagnosis reduced the risk of death prior to planned cardiac surgery relative to patients with a comparable postnatal diagnosis. Further study and efforts to improve prenatal diagnosis of congenital heart disease should therefore be considered.

Fetal aortic valvuloplasty: investigating institutional bias in surgical decision-making. ULTRASOUND IN OBSTETRICS & GYNECOLOGY : THE OFFICIAL JOURNAL OF THE INTERNATIONAL SOCIETY OF ULTRASOUND IN OBSTETRICS AND GYNECOLOGY 2014; 44:538-544. [PMID: 24975801 DOI: 10.1002/uog.13447] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/24/2014] [Revised: 06/12/2014] [Accepted: 06/12/2014] [Indexed: 06/03/2023]
Abstract
OBJECTIVES Fetal aortic valvuloplasty may prevent the progression of aortic stenosis to hypoplastic left heart syndrome and allow biventricular rather than univentricular postnatal treatment. This study aimed to investigate whether blinded simulation of a multidisciplinary team approach aids interpretation of multicenter data to uncover institutional bias in postnatal decision-making following fetal cardiac intervention for aortic stenosis. METHODS The study included 109 cases of prenatally diagnosed aortic stenosis from 13 European countries, of which 32 had undergone fetal cardiac intervention. The multidisciplinary team, blinded to fetal cardiac intervention, institutional location and postnatal treatment, retrospectively assigned a surgical pathway (biventricular or univentricular) based on a review of recorded postnatal imaging and clinical characteristics. The team's decisions were the numerical consensus of silent voting, with case review when a decision was split. Funnel plots showing concordance between the multidisciplinary team and the local team's surgical choice (first pathway) and with outcome (final pathway) were created. RESULTS In 105 cases the multidisciplinary team reached a consensus decision regarding the surgical pathway, with no decision in four cases because the available imaging records were inadequate. Blinded multidisciplinary team consensus for the first pathway matched the decision of the surgical center in 93/105 (89%) cases, with no difference in agreement between those that had undergone successful fetal cardiac intervention (n = 32) and no (n = 74) or unsuccessful (n = 3) valvuloplasty (no fetal cardiac intervention) (κ = 0.73 (95% CI, 0.38-1.00) vs 0.74 (95% CI, 0.51-0.96)). However, funnel plots comparing multidisciplinary team individual decisions with those of the local teams displayed more discordance (meaning biventricular-univentricular conversion) for the final surgical pathway following fetal cardiac intervention than they did for cases without such intervention (36/74 vs 34/130; P = 0.002), and identified one outlying center. CONCLUSIONS The use of a blinded multidisciplinary team to simulate decision-making and presentation of data in funnel plots may assist in the interpretation of data submitted to multicenter studies and permit the identification of outliers for further investigation. In the case of aortic stenosis, a high level of agreement was observed between the multidisciplinary team and the surgical centers, but one outlying center was identified.

Abstract
BACKGROUND The goal of this statement is to review available literature and to put forth a scientific statement on the current practice of fetal cardiac medicine, including the diagnosis and management of fetal cardiovascular disease. METHODS AND RESULTS A writing group appointed by the American Heart Association reviewed the available literature pertaining to topics relevant to fetal cardiac medicine, including the diagnosis of congenital heart disease and arrhythmias, assessment of cardiac function and the cardiovascular system, and available treatment options. The American College of Cardiology/American Heart Association classification of recommendations and level of evidence for practice guidelines were applied to the current practice of fetal cardiac medicine. Recommendations relating to the specifics of fetal diagnosis, including the timing of referral for study, indications for referral, and experience suggested for performance and interpretation of studies, are presented. The components of a fetal echocardiogram are described in detail, including descriptions of the assessment of cardiac anatomy, cardiac function, and rhythm. Complementary modalities for fetal cardiac assessment are reviewed, including the use of advanced ultrasound techniques, fetal magnetic resonance imaging, and fetal magnetocardiography and electrocardiography for rhythm assessment. Models for parental counseling and a discussion of parental stress and depression assessments are reviewed. Available fetal therapies, including medical management for arrhythmias or heart failure and closed or open intervention for diseases affecting the cardiovascular system such as twin-twin transfusion syndrome, lung masses, and vascular tumors, are highlighted. Catheter-based intervention strategies to prevent the progression of disease in utero are also discussed. Recommendations for delivery planning strategies for fetuses with congenital heart disease including models based on classification of disease severity and delivery room treatment will be highlighted. Outcome assessment is reviewed to show the benefit of prenatal diagnosis and management as they affect outcome for babies with congenital heart disease. CONCLUSIONS Fetal cardiac medicine has evolved considerably over the past 2 decades, predominantly in response to advances in imaging technology and innovations in therapies. The diagnosis of cardiac disease in the fetus is mostly made with ultrasound; however, new technologies, including 3- and 4-dimensional echocardiography, magnetic resonance imaging, and fetal electrocardiography and magnetocardiography, are available. Medical and interventional treatments for select diseases and strategies for delivery room care enable stabilization of high-risk fetuses and contribute to improved outcomes. This statement highlights what is currently known and recommended on the basis of evidence and experience in the rapidly advancing and highly specialized field of fetal cardiac care.

INTERVENTION A semistructured face-to-face interview was conducted to explore parental experiences, and a Structured Clinical Interview for Diagnosis-Clinical Version (posttraumatic stress disorder module) was conducted to determine the possibility of an acute stress disorder or a posttraumatic stress disorder. MEASUREMENT AND MAIN RESULTS All parents reported multiple stresses which commenced with their infant's diagnosis and endured throughout their infant's time in PICU. The Structured Clinical Interview for Diagnosis revealed that acute stress disorder or posttraumatic stress disorder developed in 24 parents (83%). Of 18 parents whose infants were diagnosed with hypoplastic left heart syndrome in utero, eight of nine mothers (88%) and six of nine fathers (66%) had posttraumatic stress disorder. Of 11 parents whose infants were diagnosed with hypoplastic left heart syndrome postbirth, six of seven mothers had acute stress disorder and one mother had posttraumatic stress disorder, and of four fathers, two fathers had acute stress disorder and one father had posttraumatic stress disorder. The prevalence of parental stress-related disorder was not different between mothers and fathers (p = 0.85). Only five parents were free of traumatic stress-related illness. Parents also experienced losses. Many parents were marginalized from their infant's care by the environment of PICU. Fifty percent of mothers experienced difficulties with parental-infant bonding. Ten parents (34%) began the process of adaptation to their infant's hypoplastic left heart syndrome and were assisted by the support and sensitivity of staff or had discovered other resources. CONCLUSIONS All parents of surviving infants with hypoplastic left heart syndrome in PICU, irrespective of timing of diagnosis, experienced numerous stresses and losses, and the majority exhibited clinical levels of traumatic stress. Receiving the diagnosis itself is very traumatic and is compounded by the environment of the PICU which alienates parents from their infants and interferes with parent-infant bonding. Parental adaptation to this situation can be assisted by staff.

Abstract
This study was undertaken to examine the impact that prenatal diagnosis of congenital heart disease (CHD) has on birth and early neonatal outcomes. The prevalence of prenatally diagnosed CHD has risen over the past decade, but the effect that prenatal diagnosis of CHD has on peripartum decisions remains unclear. No consensus exists on the effect of prenatal diagnosis on neonatal outcomes. Between January 2004 and July 2009, a retrospective chart review of all neonates with CHD admitted to our institution's neonatal intensive care unit was conducted. Obstetric and postnatal variables were collected. Among the 993 subjects, 678 (68.3%) had a prenatal diagnosis. A prenatal diagnosis increased the odds of a scheduled delivery [odds ratio (OR) 4.1, 95% confidence interval (CI) 3.0-5.6] and induction of labor (OR 11.5, 95% CI 6.6-20.1). Prenatal diagnosis was not significantly associated with cesarean delivery when control was used for maternal age, multiple gestation, and presence of extracardiac anomaly. Mean gestational age had no impact on prenatal diagnosis, but prenatal diagnosis was associated with increased odds of delivery before a gestational age of 39 weeks (OR 1.5, 95% CI 1.1-1.9) and decreased odds of preoperative intubation (OR 0.5, 95% CI 0.3-0.6). Prenatal diagnosis did not have an impact on preoperative or predischarge mortality. Prenatal diagnosis was associated with increased odds of a scheduled delivery, birth before a gestational age of 39 weeks, and a decreased need for invasive respiratory support. Prenatal diagnosis of CHD was not associated with preoperative or predischarge mortality.

Abstract
Infants born with hypoplastic left heart syndrome or other lesions resulting in a single right ventricle face the highest risk of mortality among all forms of congenital heart disease. Before the modern era of surgical palliation, these conditions were universally lethal; recent refinements in surgical technique and perioperative management have translated into dramatic improvements in survival. Nonetheless, these infants remain at a high risk of morbidity and mortality, and an appreciation of single ventricle physiology is fundamental to the care of these high-risk patients. Herein, resuscitation and perioperative management of infants with hypoplastic left heart syndrome are reviewed. Basic neonatal and pediatric life support recommendations are summarized, and perioperative first-stage clinical management strategies are reviewed.

Abstract
The objective of the present study was to characterize the outcomes and resource utilization of all infants born with hypoplastic left heart syndrome (HLHS) in the Intermountain West. This was a retrospective cohort study of all infants born with HLHS in the Intermountain West from January 1995 and January 2010. The cohort was divided into 3 eras: era 1, 1995 to 1999; era 2, 2000 to 2004; and era 3, 2005 to 2010. Cox proportional hazards regression analysis was performed to assess mortality. The lifetime hospitalization days and charges were also determined. Of the 245 infants identified, 65% were male infants and 172 (70%) underwent Stage 1 palliation. The transplant-free survival rate for the entire cohort was 33% at 14 years. The 1-year transplant-free survival rate for the surgical cohort was 60% in era 3. The infants whose initial presentation included shock, restrictive or intact atrial septum, chromosomal defects, or multiorgan dysfunction had an increased risk of death. A recent era of birth, greater birthweight, and older gestational age were associated with improved survival. The factors associated with mortality after stage 1 included surgical procedure type (Blalock-Taussig vs Sano shunt, hazard ratio 2.1), requirement for postoperative extracorporeal membrane oxygenation (hazard ratio 4.2), postoperative renal dysfunction (hazard ratio 3.0), anomalous pulmonary venous return (hazard ratio 2.9), and moderate or greater tricuspid valve regurgitation at any point (hazard ratio 2.0). For patients who had undergone stage 1, 2, or 3 palliation, the median cumulative lifetime hospitalization was 32, 48, and 65 days, and the median cumulative lifetime charges for hospitalization were $201,812, $253,183, and $296,213, respectively. In conclusion, although hospital-based studies of HLHS have shown significantly improved survival after surgical palliation, population-based studies have shown that HLHS continues to have a high mortality and high resource utilization.

Abstract
The Family Management Style Framework (FMSF) was used as a conceptual basis for secondary data analysis of 55 previously conducted interviews with mothers and fathers of children with a lethal congenital condition from two surgical treatment eras. The directed content analysis was guided by a coding structure developed from family management dimensions identified in prior research of family response to childhood chronic conditions. Results indicated that application of the FMSF was helpful in differentiating families and their processes of family management at the onset of their infant's illness through to surviving the first surgery and going home. The dimensions of Illness View and Child Identity were central to the parents' capacity to manage their baby's illness demands within their family context. Applying a robust family framework to a complex neonatal condition at illness onset provides compelling direction for clinical interventions and their rigorous evaluation.

Abstract
Hypoplastic left heart syndrome is a rare condition requiring major cardiac surgery during the neonatal period to sustain life, with subsequent procedures culminating in completion of the Fontan circulation - the common pathway for all 'single ventricle' conditions. Algorithms for care of these children are now well defined with predictable medium-term outcomes with the majority achieving a Fontan circulation. Hypoplastic left heart syndrome is one of a group of conditions that require complex surgery as a neonate and require a similar perioperative approach. Antenatal diagnosis is common in this patient subgroup, and there is a significant body of work that can be drawn on to inform parental choice.

Abstract
BACKGROUND AND AIMS Several years ago, one of us described the difference in attitude to patients with hypoplastic left heart syndrome in the United States of America and Europe as similar to that between Mars and Venus. Uncertainty remains with regard to the long-term prognosis for patients with hypoplastic left heart syndrome. This prognosis may be considered in terms of survival, functional performance, including exercise capacity and neurodevelopment, as well as psychosocial effects on the patient, family, and siblings. Counselling parents where either an antenatal or postnatal diagnosis of hypoplastic left heart syndrome has been made requires practitioners to give information on these prognostic aspects. We wanted to see how attitudes among European surgeons have changed over the last few years. METHODS We performed a review of recent European data for hypoplastic left heart syndrome and conducted a survey among surgeons in major European centres to ascertain key aspects of their attitudes to the management of patients with hypoplastic left heart syndrome and how they counsel parents. RESULTS AND CONCLUSIONS As of January, 2011, 2392 citations in the PubMed database were available for the search string "hypoplastic left heart". The majority of these were from the centres from the United States of America and Europe. The European Association for Cardio-Thoracic Surgery Congenital Heart Surgery Database shows an annual increase in the number of Norwood (Stage I) operations for hypoplastic left heart syndrome from 2003 to 2009, with a corresponding reduction in mortality. European rates of antenatal detection vary widely between centres, as do the rates of termination for a prenatal diagnosis of hypoplastic left heart syndrome. We observed a wide variation in the estimates of surgeons for survival and quality of life for surgical palliation of hypoplastic left heart syndrome, as well as in their estimates for actual rates of termination of pregnancy in their centres. Further, there was marked inconsistency in the information given to parents as part of the process of counselling. These issues remain to be resolved if parents are to make a fully informed decision for their child.

Abstract
Hypoplastic left heart syndrome remains one of the most challenging pathologies in pediatric cardiac surgery. The surgical techniques, and anesthetic and intensive care management, have evolved over the last decades, which has resulted in improved outcomes. A central component in the postoperative management of hypoplastic left heart syndrome patients is to achieve an optimal balance between the pulmonary and systemic circulations. This article discusses the contemporary postoperative management of pulmonary and systemic circulations in detail.

Abstract
PURPOSE. This study described the role normalization played for parents related to their young children with hypoplastic left heart syndrome. DESIGN AND METHODS. The data source for this secondary analysis was 30 interviews with 16 parents. RESULTS. Three themes were identified: normalization, parental perception of child vulnerability, and optimistic appraisal. Parents engaged in a balancing act between worrying about their children's vulnerability and marveling at their children's survival, using normalization as a coping strategy. PRACTICE IMPLICATIONS. Nurses can collaborate with parents to determine strategies to restore a sense of normalcy to simultaneously promote child independence and parent well-being.

Abstract
OBJECTIVE To establish what bereavement care services are available in neonatal units in the United Kingdom and to establish the availability to staff (doctors, nurses, and chaplains) of bereavement education, training, communication, and multicultural support. For families who lose a baby in the neonatal period, the support they receive from hospital staff can be pivotal in their ability to cope with their grief. Hospital staff are not always trained to provide this support. Limited evidence is available regarding hospital-based bereavement care in neonatology or its impact on outcome. INTERVENTIONS Questionnaire survey of selected doctors, nurses, and chaplains in 200 neonatal units in the United Kingdom. MEASUREMENTS AND MAIN RESULTS We had responses from 100% of neonatal units surveyed. Of 600 individuals, 320 responded; 11% of doctors had never received any formal training in bereavement care, compared with 0.8% of nurses and 1.2% and chaplains. In addition, 31% of respondents thought the training they received was inadequate. Knowledge of grief theorists was poor. Up to 99% of units were helping parents create memories through photographs or handprints. Parents were uniformly given the chance to be with their baby at the time of death (99% overall). Siblings were encouraged to be present 71% of the time; 75% of respondents felt that information about the needs of different faith groups was available. Formal psychological support was offered to 45% of families after bereavement. CONCLUSIONS Studies have shown that parents value clear communication, education about grieving, and demonstrated emotional support by staff. Our study has shown that there are deficiencies in staff training and education in this area. Educators must promote the inclusion of content on bereavement/end-of-life care. Additional education on cultural issues would be helpful. Managing the bereavement process well to minimize morbidity for families and healthcare providers is an important challenge for the future.

Abstract
Neonatal intensive care units (NICUs) and medical intensive care units (MICUs) are both very expensive. The cost-effectiveness of NICUs has been extensively evaluated, as has the long-term outcomes of subpopulations of NICU patients. NICU treatment is among the most cost-effective of high-tech interventions. And most patients do well. There are fewer evaluations of cost-effectiveness in the MICU and almost no long-term outcome studies. Policymakers who scrutinize expensive high-tech interventions would do well to study the examples found in the NICU.

Abstract
Parents of children diagnosed with a complex congenital heart anomaly such as hypoplastic left heart syndrome (HLHS) are faced with the challenge of choosing the best treatment option for their children. Parents must decide among options of compassionate care, palliative reconstructive surgery, or neonatal cardiac transplantation, and additionally with antenatal diagnosis must decide regarding continuation of pregnancy. With improved survival rates yet persistent morbidities following the Norwood surgical approach for HLHS, controversy remains whether parents should be counseled on all treatment options as evidenced by research that articulates the varied opinions of health care providers. The parents' perspective is less well researched. In this study, interview data from parents who chose the Norwood-Sano surgical option were analyzed to provide insight into the various treatment options they were given following diagnosis of HLHS in their children and how they came to choose the surgical palliation option.

Abstract
OBJECTIVES To review our experience with the prenatal diagnosis of hypoplastic left heart syndrome (HLHS). Our goal was to establish the benchmark for perinatal and early surgical outcome in the current era, from a center with an aggressive surgical approach and a cohort with a high level of intention-to-treat. METHODS Outcome was assessed in fetuses with HLHS following stratification into high-risk and standard-risk categories. High risk was defined as the presence of any of the following: extracardiac, genetic or chromosomal anomalies; prematurity of < 34 weeks' gestation; additional cardiac findings such as intact or highly restrictive atrial septum, severe degree of tricuspid regurgitation or severe ventricular dysfunction. Standard risk was defined as absence of these risk factors. RESULTS Of 240 fetuses evaluated over 5 years, 162 (67.5%) were in the standard-risk group and 78 (32.5%) were in the high-risk group. Of the 240 sets of parents, 38 (15.8%) chose termination or non-intervention at birth at initial prenatal counseling and 185 of the neonates (77.1%) underwent first-stage Norwood surgery with 155 surviving and 30 deaths, giving an overall Norwood operative survival of 83.8%. Breakdown by risk class reveals a significant Norwood operative survival advantage for the standard-risk group (92.8%) over the high-risk group (56.5%) (P < 0.001). CONCLUSIONS Following prenatal diagnosis of HLHS, families should be strongly encouraged to undertake comprehensive prenatal evaluation in order to obtain an accurate prognosis. One-third have additional risk factors that limit survival outcome, however two-thirds do not and have an excellent chance of early survival.

Abstract
OBJECTIVES The purpose of this analysis was to assess preoperative risk factors before the first-stage Norwood procedure in infants with hypoplastic left heart syndrome and related single-ventricle lesions and to evaluate practice patterns in prenatal diagnosis, as well as the role of prenatal diagnosis in outcome. METHODS Data from all live births with morphologic single right ventricle and systemic outflow obstruction screened for the Pediatric Heart Network's Single Ventricle Reconstruction Trial were used to investigate prenatal diagnosis and preoperative risk factors. Demographics, gestational age, prenatal diagnosis status, presence of major extracardiac congenital abnormalities, and preoperative mortality rates were recorded. RESULTS Of 906 infants, 677 (75%) had prenatal diagnosis, 15% were preterm (<37 weeks' gestation), and 16% were low birth weight (<2500 g). Rates of prenatal diagnosis varied by study site (59% to 85%, P < .0001). Major extracardiac congenital abnormalities were less prevalent in those born after prenatal diagnosis (6% vs 10%, P = .03). There were 26 (3%) deaths before Norwood palliation; preoperative mortality did not differ by prenatal diagnosis status (P = .49). In multiple logistic regression models, preterm birth (P = .02), major extracardiac congenital abnormalities (P < .0001), and obstructed pulmonary venous return (P = .02) were independently associated with preoperative mortality. CONCLUSIONS Prenatal diagnosis occurred in 75%. Preoperative death was independently associated with preterm birth, obstructed pulmonary venous return, and major extracardiac congenital abnormalities. Adjusted for gestational age and the presence of obstructed pulmonary venous return, the estimated odds of preoperative mortality were 10 times greater for subjects with a major extracardiac congenital abnormality.

Abstract
Hypoplastic left heart syndrome is a rare congenital heart defect in which the left side of the heart is underdeveloped. Surgical management of hypoplastic left heart syndrome has changed the prognosis of the condition that was previously regarded as fatal. We discuss surgical strategies based on staged procedures, with the right ventricle supporting both systemic and pulmonary circulation. We also discuss other management options, such as neonatal transplantation and the recent innovation of hybrid techniques. Surgical techniques and the understanding of the pathophysiology of this condition have been at the forefront of neonatal cardiac surgery and intensive care. The management of the syndrome remains a challenge because affected children grow into adolescence and adulthood posing various new problems and demands.

Abstract
Congenital heart defects are the most common of all congenital malformations, with a review of the literature reporting the incidence at 6 to 8 per 1000 live births. The Centers for Disease Control reports cyanotic heart defects occurred in 56.9 per 100,000 live births in the United States in 2005, with higher rates noted when maternal age exceeded 40 years. The incidence of congenital heart disease in premature infants is 12.5 per 1000 live births, excluding isolated patent ductus arteriosus and atrial septal defect. Despite advances in detection and treatment, congenital heart disease accounts for 3% of all infant deaths and 46% of death from congenital malformations. This article discusses the embryology, pathogenesis, clinical presentation, incidence, classifications, and management of congenital heart diseases.

OBJECTIVES To analyze the main prenatal characteristics of hypoplastic left heart syndrome (HLHS), its association with extracardiac anomalies including increased nuchal translucency (NT) and the outcome of affected patients. METHODS We searched our database for classical forms of HLHS (aortic atresia, mitral and aortic atresia and critical aortic stenosis evolved to a severely hypoplastic left ventricle) prenatally diagnosed between 1998 and 2006. Data on 101 fetuses were retrieved and analyzed. RESULTS The main reason for referral was suspected heart defect on a routine ultrasound scan (82%). The mean gestational age at diagnosis was 21 weeks. Most cases were detected at < or = 22 weeks (72%), the upper limit for termination of pregnancy (TOP) in our country (Spain). An intact atrial septum was diagnosed in 11 of the 58 fetuses (19%) in which pulmonary vein blood flow was assessed, and this diagnosis was proved to be correct in the six liveborn babies. Most fetuses (68%) had an isolated HLHS. Fourteen fetuses (14%) were chromosomally abnormal and all had associated extracardiac defects. NT was above the 95th centile in 21 of the 74 cases (28%) in which this measurement was available. 79% (58/73) of the cases in which HLHS was detected at < or = 22 weeks were terminated, and no differences in the rate of TOP were found through the study period. Among the 43 continuing pregnancies, seven fetuses died in utero and there were 36 live births; in 12 cases the parents opted for compassionate care and 24 chose to have the infant surgically treated. In the cohort of intention-to-treat cases, the overall survival rate was 36% (9/25). This rate improved from 18% (2/11) in the period 1998-2002 to 50% (7/14) in 2003-2006. There were no survivors in cases with intact atrial septum or when there were associated defects. At follow-up, 2/9 survivors suffered from significant neurological morbidity. CONCLUSIONS Fetal echocardiography allows an accurate diagnosis of HLHS, which is made in most instances in the first half of pregnancy. Despite the advantage offered by the prenatal detection of HLHS, which provides the opportunity to plan perinatal management, our up-to-date results show that the outlook for these fetuses is still poor, and highlight the importance of presenting these figures when counseling parents with affected fetuses.

Abstract
Currently, a three-stage surgical palliation remains the treatment of choice at Birmingham Children's Hospital. After initial introduction of the classical Norwood with pulmonary blood flow provided by a modified Blalock-Taussig shunt, a right ventricular to right pulmonary artery conduit at stage 1 Norwood palliation is now used in most cases, a bi-directional 'Glenn' shunt at second stage and an extra-cardiac Fontan completion at third stage. Mortality and morbidity has improved after modification of the technique. Thirty-day mortality was 32.4% (79/244) for the 'classical' Norwood procedure, 25.0% (7/28) for the left-sided RV-PA conduit and 12.7% (22/173) for the right-sided RV-PA conduit. Interstage mortality was 8.6% (21/244) for the 'classical' Norwood procedure, 14.3% (4/28) for the left and 10.1% (15/148) for right-sided RV-PA conduit. After stage II, 30-day mortality was 3.0% (10/335) for all groups. Stage III 30-day mortality was 0.9% (1/115) for all groups.
