Cause, severity, and efficacy of treatment for hearing loss in children with Trisomy 18: A single institution-based retrospective study. Am J Med Genet A 2024; 194:e63492. [PMID: 38062644 DOI: 10.1002/ajmg.a.63492] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/26/2023] [Revised: 10/30/2023] [Accepted: 11/14/2023] [Indexed: 03/10/2024]
Abstract
Trisomy 18 is a common chromosomal aberration syndrome, characterized by variable clinical manifestations, including cardiovascular, pulmonary, genitourinary, and musculoskeletal findings, leading to a shorter survival and severe developmental delay in survivors. However, recently, intensive therapeutic intervention has allowed for prolonging survival. In terms of otological complications, only a limited number of relevant reports have been published. To demonstrate the characteristic of hearing loss (HL) in children with Trisomy 18, we retrospectively evaluated 22 patients (44 ears) by comprehensive auditory evaluation with the auditory steady-state response (ASSR) test and temporal bone computed tomography (CT). ASSR revealed that 20 patients (91%) had bilateral moderate to profound HL, more frequent and severe than that in Trisomy 21; among 42 ears having HL, 12 ears (29%) had conductive HL, and 26 ears (62%) had mixed HL. CT scans of 38 ears revealed that 34 ears (89%) had an external and middle ear malformation. Hearing aids (HA) were fitted in 17 patients (air and bone-conduction HAs). The threshold hearing with HA was improved in all of them. Accurate otological evaluation using ASSR and CT and intervention by HAs could be a feasible choice for children with Trisomy 18.

Causes of death in individuals with trisomy 18 after the first year of life. Am J Med Genet A 2024; 194:279-287. [PMID: 37822198 DOI: 10.1002/ajmg.a.63436] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/31/2023] [Revised: 09/20/2023] [Accepted: 09/27/2023] [Indexed: 10/13/2023]
Abstract
Mortality in individuals with trisomy 18 has significantly decreased over the past 20 years, but there is scant literature addressing the prognosis and cause of death in individuals with trisomy 18 and survival past the first year of life (YOL). This study analyzed factors associated with mortality and cause of death in a retrospective cohort of 174 individuals with trisomy 18 and survival past the first YOL, the largest such series to date. Data were collected via retrospective survey of parents of affected individuals. Prenatal diagnosis of trisomy 18; postnatal respiratory distress; maternal age > 35 years; birthweight <2000 g; brain and spinal cord defect(s); atrial and/or ventricular septal defect(s); inability to feed orally without medical assistance; and failure to meet sitting and rolling milestones were associated with mortality in this sample. Cause of death was compared between our cohort of individuals with trisomy 18 and existing literature on those with mortality before the first YOL. Individuals with trisomy 18 with mortality after the first YOL demonstrated a predominance of infectious (n = 10/22) and postoperative (n = 6/22) contributing causes of death, in contrast to the existing literature, which shows a predominance of cardiopulmonary causes of death (e.g., cardiopulmonary arrest, pulmonary hypertension). These findings demonstrate that individuals with trisomy 18 and survival past the first YOL have unique medical needs, but further research is needed to develop clinical guidelines for this growing population.

Significant improvement in survival outcomes of trisomy 18 with neonatal intensive care compared to non-intensive care: a single-center study. PeerJ 2023; 11:e16537. [PMID: 38047023 PMCID: PMC10693230 DOI: 10.7717/peerj.16537] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/30/2023] [Accepted: 11/07/2023] [Indexed: 12/05/2023] Open
Abstract
Background Trisomy 18 syndrome, also known as Edwards syndrome, is a chromosomal trisomy. The syndrome has historically been considered lethal owing to its poor prognosis, and palliative care was primarily indicated for trisomy 18 neonates. Although there have been several reports on the improvement of survival outcomes in infants with trisomy 18 syndrome through neonatal intensive care, few studies have compared the impact of neonatal intensive care on survival outcomes with that of non-intensive care. Therefore, we compared the survival-related outcomes of neonates with trisomy 18 between intensive and non-intensive care. Methods Seventeen infants of trisomy 18 admitted to our center between 2007 and 2019 were retrospectively studied. We divided the patients into a non-intensive group (n = 5) and an intensive group (n = 12) and evaluated their perinatal background and survival-related outcomes of the two groups. Results The 1- and 3-year survival rates were both 33% in the intensive group, which was significantly higher than that in the non-intensive group (p < 0.001). Half of the infants in the intensive care group were discharged alive, whereas in the non-intensive care group, all died during hospitalization (p = 0.049). Conclusions Neonatal intensive care for neonates with 18 trisomy significantly improved not only survival rates but also survival-discharge rates. Our findings would be helpful in providing 18 trisomy neonates with standard neonatal intensive care when discussing medical care with their parents.

Abstract
OBJECTIVE To evaluate the correlation of high levels [>2.0 multiples of median (MoM)] of amniotic fluid alpha-fetoprotein (AFAFP) in midtrimester with abnormal fetal outcome. MATERIALS AND METHODS We retrospectively studied 6245 pregnant women with singleton pregnancy who had undergone amniocentesis between 15 and 27 weeks' gestation at Mackay Memorial Hospital between January 2014 and June 2020. Fifty-five cases had high AFAFP levels (>2.0 MoM). We investigated the abnormal fetal outcomes. RESULTS Among the fifty-five cases with high AFAFP levels (>2.0 MoM), thirty (54.5%) had fetal chromosomal abnormalities, major structural abnormalities, and/or adverse obstetric events. Eight cases (14.5%) had chromosomal abnormalities including trisomy 21 (3 cases), trisomy 18 (3 cases), mosaic trisomy 18 (1 cases), and mosaic ring 13 (1 case). Seventeen cases (30.9%) had major structural abnormalities including abdominal wall defect (6 cases) and central nervous system (5 cases), gastrointestinal tract (3 cases), cardiovascular (2 cases), and genitourinary tract (2 cases) abnormalities. Fifteen cases (27%) had adverse obstetric events, including preterm delivery (5 cases), intrauterine fetal demise (4 cases), small for gestational age (4 cases), preeclampsia (4 cases), gestational diabetes mellitus (2 cases), gestational hypertension (1 case), preterm prelabor rupture of membrane (1 case), prolonged labor (1 case), and preterm uterine contraction (1 case). CONCLUSION A high AFAFP level (>2.0 MoM) in midtrimester can be associated with abnormal fetal outcome, including chromosomal abnormalities, major structural abnormalities, and adverse obstetric events. Women with a prenatal diagnosis of high AFAFP levels (>2.0 MoM) should be alerted of the possibility of abnormal fetal outcomes, and further detailed genetic studies and serial sonographic examinations are recommended.

Effectiveness of cardiac palliative surgery for trisomy 18 patients with increased pulmonary blood flow. Am J Med Genet A 2023; 191:2703-2710. [PMID: 37698299 DOI: 10.1002/ajmg.a.63401] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/01/2023] [Revised: 07/25/2023] [Accepted: 08/30/2023] [Indexed: 09/13/2023]
Abstract
Congenital heart disease (CHD) is common among patients with trisomy 18 (T18), but cardiac surgery has been rarely indicated for T18 patients due to their short life span. Although the therapeutic effects of aggressive interventions were recently demonstrated for T18 patients, the subjects and factors examined varied, resulting in inconsistent findings. Therefore, the effects of cardiac surgery for T18 remain unclear. We herein investigated the outcomes of cardiac palliative surgery for CHD with increased pulmonary blood flow in T18 patients. 27 patients were examined: 13 (48.1%) underwent cardiac palliative surgery and 14 (51.9%) did not. Median survival times in the no-surgery and surgery groups were 223.0 days (95% confidence interval [CI]: 46-361 days) and 723.0 days (95% CI: 360-1447 days), respectively. The number of patients with pulmonary hypertension significantly differed between the two groups (5 of 14 in the no-surgery group and 0 in the surgery group). Five of 14 patients in the no-surgery group and 10 of 13 in the surgery group were discharged to home care (odds ratio: 10.8 [95% CI: 1.07-110.0]). Therefore, cardiac palliative surgery may be used to treat CHD with increased pulmonary blood flow in T18 patients.

Recent Advances in Pediatric Pulmonary Hypertension: Implications for Diagnosis and Treatment. Clin Ther 2023; 45:901-912. [PMID: 37517916 DOI: 10.1016/j.clinthera.2023.07.001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/27/2023] [Revised: 07/03/2023] [Accepted: 07/06/2023] [Indexed: 08/01/2023]
Abstract
PURPOSE Pediatric pulmonary hypertension (PH) is a condition characterized by elevated pulmonary arterial pressure, which has the potential to be life-limiting. The etiology of pediatric PH varies. When compared with adult cohorts, the etiology is often multifactorial, with contributions from prenatal, genetic, and developmental factors. This review aims to provide an up-to-date overview of the causes and classification of pediatric PH, describe current therapeutics in pediatric PH, and discuss upcoming and necessary research in pediatric PH. METHODS PubMed was searched for articles relating to pediatric pulmonary hypertension, with a particular focus on articles published within the past 10 years. Literature was reviewed for pertinent areas related to this topic. FINDINGS The evaluation and approach to pediatric PH are unique when compared with that of adults, in large part because of the different, often multifactorial, causes of the disease in children. Collaborative registry studies have found that the most common disease causes include developmental lung disease and subsets of pulmonary arterial hypertension, which includes genetic variants and PH associated with congenital heart disease. Treatment with PH-targeted therapies in pediatrics is often guided by extrapolation of adult data, small clinical studies in pediatrics, and/or expert consensus opinion. We review diagnostic considerations and treatment in some of the more common pediatric subpopulations of patients with PH, including developmental lung diseases, congenital heart disease, and trisomy 21. IMPLICATIONS The care of pediatric patients with PH requires consideration of unique pediatric-specific factors. With significant variability in disease etiology, ongoing efforts are needed to optimize treatment strategies based on disease phenotype and guide evidence-based practices.

Ethical Implications of Cleft Lip and Palate Repair in Patients with Trisomy 13 and Trisomy 18. Cleft Palate Craniofac J 2023:10556656231163722.

Abstract
BACKGROUND Children born with Trisomy 13 or 18 (T13/18) often have multiple congenital anomalies, many of which drastically shorten their lifespan. Among these defects are cleft lip and palate, the repair of which presents an ethical dilemma to the surgeon given the underlying comorbidities associated with T13/18. The authors present an ethical discussion and institutional experience in navigating this dilemma. METHODS The authors analyzed existing literature on T13 and T18 surgery and mortality. A retrospective study over ten years was also conducted to identify pediatric patients who underwent surgical correction of cleft lip and/or palate secondary to a confirmed diagnosis of T13/18. The authors identified two patients and examined their treatment course. RESULTS The authors' review of literature coupled with their institution's experience builds on the published successes of correcting cleft lip and palate in the setting of T13/18. It was found that both patients identified in the case series underwent successful correction with no surgical complications. CONCLUSION A careful balance must be struck between improved quality of life, benefits of treatment, and risks of surgery in children with T13/T18. Careful consideration should be given to the medical status of these complex patients. If the remaining medical comorbidities are well managed and under control, there is an ethical precedent for performing cleft lip and palate surgeries on these children. A diagnosis of T13/T18 alone is not enough to disqualify patients from cleft lip/palate surgery.

Abstract
OBJECTIVE To investigate the survival to 10 years of age of children with trisomy 13 (T13) and children with trisomy 18 (T18), born 1995-2014. DESIGN Population-based cohort study that linked mortality data to data on children born with T13 or T18, including translocations and mosaicisms, from 13 member registries of EUROCAT, a European network for the surveillance of congenital anomalies. SETTING 13 regions in nine Western European countries. PATIENTS 252 live births with T13 and 602 with T18. MAIN OUTCOME MEASURES Survival at 1 week, 4 weeks and 1, 5 and 10 years of age estimated by random-effects meta-analyses of registry-specific Kaplan-Meier survival estimates. RESULTS Survival estimates of children with T13 were 34% (95% CI 26% to 46%), 17% (95% CI 11% to 29%) and 11% (95% CI 6% to 18%) at 4 weeks, 1 and 10 years, respectively. The corresponding survival estimates were 38% (95% CI 31% to 45%), 13% (95% CI 10% to 17%) and 8% (95% CI 5% to 13%) for children with T18. The 10-year survival conditional on surviving to 4 weeks was 32% (95% CI 23% to 41%) and 21% (95% CI 15% to 28%) for children with T13 and T18, respectively. CONCLUSIONS This multi-registry European study found that despite extremely high neonatal mortality in children with T13 and T18, 32% and 21%, respectively, of those who survived to 4 weeks were likely to survive to age 10 years. These reliable survival estimates are useful to inform counselling of parents after prenatal diagnosis.

Abstract
OBJECTIVE Many studies, largely from high-income countries (HIC), have reported outcomes in babies with trisomy 18 (T18), with a paucity of data from Africa. Knowledge of outcomes is important in counselling women prenatally diagnosed with T18. We aimed to review all prenatally diagnosed cases of T18 between January 2006 and December 2021. METHOD Demographic data, diagnosis, gestation and outcome data were obtained from the Astraia® database and patient files. RESULTS We included 88 pregnant women of whom 46 terminated their pregnancies (30 beyond 24 weeks' gestation). Three underwent foeticides, one had a caesarean section for maternal obstetric reasons and 26 underwent inductions of labour without foetal monitoring. Four neonates were live born but none lived >8 h. In those who continued their pregnancies, the mean gestation at delivery was 34.8 weeks, 14 (33%) were live births and only 5 survived for >24 h with none surviving to 1 year of life. CONCLUSION In our cohort, infants with T18 had lower live birth rates and shorter survival than in the current literature from HIC. This may be due to the implementation of non-aggressive intrapartum care and comfort care for the neonates. This has implications for counselling in our setting.

Abstract
UNLABELLED Trisomy 18 is an autosomal chromosomal disorder characterized by the presence of an extra 18 chromosome. In the last decades, and as novel therapeutic options emerged, a paradigm shift on the treatments available to these children occurred, establishing the need to deepen the knowledge regarding the management/treatment of children diagnosed with trisomy 18. This retrospective cohort study sought to characterize the clinical path and survival of the children with the diagnosis of trisomy 18 followed in a tertiary pediatric hospital between 1995 and 2020. Medical records were reviewed, and epidemiological and clinical features and follow-up data were collected. Six patients were identified, two with mosaicism (33.3%) and four were female (66.7%). All had cardiovascular, cognitive, and physical development anomalies or minor congenital anomalies. Most presented neurological anomalies (n = 4, 66.7%) and feeding difficulties (n = 4, 66.7%). Four children (66.7%) required medical devices or equipment and all required chronic medication. Two children (33.3%) underwent surgical interventions. Four children (66.7%) were hospitalized in the last year of life. Three patients had a do not resuscitate order (50%) but only one child was referred to a pediatric palliative care team (16.7%). One-month, 1-year, and 10-year survival were 66.7% (n = 4), 33.3% (n = 2, both with mosaicism), and 16.7% (n = 1, with mosaicism) respectively. CONCLUSIONS Knowledge of the multiple comorbidities and complex care needs of children with this syndrome is crucial. Every-day care and decisions about invasive treatments may raise ethical issues. Early referral to pediatric palliative care teams is essential to promote a holistic advanced care plan for both the patient and his family. WHAT IS KNOWN • The increase in survival and the high morbimortality that trisomy 18 still entails demands a careful deliberation on the use of invasive treatment. WHAT IS NEW • Recent studies show that the labels of "incompatible with life"/"lethal" are not adequate, establishing a need to change this mindset. • The development of pediatric palliative care teams in the last decade and early referral allow for an optimal individualized advanced care plan. Under-referral to pediatric palliative care teams persists and efforts must be made to increase awareness of their existence and role in patient care.

Abstract
OBJECTIVE Care offerings vary across medical settings and between families for babies with trisomy 13 or 18. The purpose of this qualitative descriptive study was to explore nurse, advanced practice practitioner, and neonatologist perspectives on care for babies with trisomy 13 or 18 in the intensive care unit. STUDY DESIGN Voice-recorded qualitative interviews occurred with 64 participants (41 bedside nurses, 14 advance practice practitioners, and 9 neonatologists) from two neonatal intensive care units (NICU) in the midwestern United States. Consolidated Criteria for Reporting Qualitative Research guidelines were followed. Content analyses occurred utilizing MAXQDA (VERBI Software, 2020). RESULTS Over half of NICU staff perceived care for babies with trisomy 13 or 18 as different from care for other babies with critical chronic illness. Qualitative themes included internal conflict, variable presentation and prognosis, grappling with uncertainty, family experiences, and provision of meaningful care. Neonatologists emphasized the variability of presentation and prognosis, while nurses emphasized provision of meaningful care. Phrases "hard/difficult" were spoken 31 times; primarily describing the comorbidities, complexities, and prognostic uncertainty. CONCLUSION Care for babies with these genetic diagnoses reveals need for a shared dialogue not only with families but also across staff disciplines. While perspectives differ, participants depicted striving to offer compassionate, family-centered care while also balancing biomedical uncertainty about interventions for children with trisomy 13 and 18. KEY POINTS · Care for babies with trisomy 13 or 18 has been recognized as shifting.. · Controversy exists across the diverse and changing range of care models.. · This study describes perspectives of bedside neonatal nurses, advanced practitioners, and neonatologists.. · Differences in perspectives warrant attentiveness to insights and dialogue across disciplines..

Abstract
Advances in the prognosis of relevant syndromes and severe congenital malformations in infants during the last few decades have enabled the treatment and survival of an ever-increasing number of infants, whose prospects were previously judged futile by professional health care teams. This required detailed counselling for families, which frequently started before birth when a diagnosis was made using genetic testing or ultrasound. Predictions of the estimated prognosis, and frequently the more-or-less broad range of prospects, needed to include the chances of survival and data on acute and long-term morbidities. However, in the interest of a having an informed basis for parental decision-making with a professional interdisciplinary team, this process needs to acknowledge the rights of the parents for a comprehensive presentation of the expected quality of life of their child, the potential consequences for family life, and the couple’s own relationship. Besides expert advice, professional psychological and familial support is needed as a basis for a well-founded decision regarding the best treatment options for the child. It needs to be acknowledged by the professional team that the parental estimate of a “good outcome” or quality of life does not necessarily reflect the attitudes and recommendations of the professional team. Building a mutually trusting relationship is essential to avoid decision conflicts.

Abstract
The effects of medical and surgical interventions on the survival of patients with trisomy 18 have been reported, leading to changes in perinatal management and decision-making. However, few studies have fully reported the recent changes in survival and treatment of trisomy 18. We examined how treatment and survival of patients with trisomy 18 have changed over a decade in a Japanese pediatric tertiary referral center. This retrospective cohort study included patients with trisomy 18 who were admitted within the first 7 days of life at the Hyogo Prefectural Kobe Children's Hospital between 2008 and 2017. The patients were divided into early period (EP) and late period (LP) groups based on the birth year of 2008-2012 and 2013-2017, respectively. Changes in treatment and survival rates were compared between the two groups. A total of 56 patients were studied (29 in the EP group and 27 in the LP group). One-year survival rates were 34.5% and 59.3% in the EP and LP groups, respectively. The survival to discharge rate significantly increased from 27.6% in the EP group to 81.5% in the LP group (p < 0.001). The proportion of patients receiving surgery, especially for congenital heart defects, significantly increased from 59% in the EP group to 96% in the LP group (p = 0.001). In our single-center study, survival and survival to discharge were significantly improved in patients with trisomy 18, probably because of increased rate of surgical interventions. These findings may facilitate better decision-making by patients' families and healthcare providers.

Abstract
OBJECTIVE The conventional view toward the management of infants with the trisomy 18 and trisomy 13 syndromes has been to recommend pure comfort care and the avoidance of technological interventions. This commentary aims to address the recently raised question about whether there has been a shift in the paradigm of the management of infants with the two conditions. STUDY DESIGN The study design includes narrative review of the literature. RESULTS A body of opinion pieces and evidence has emerged indicating that there has been a recent increase in the administration of interventions, including ventilatory support and surgery, in the management of children with these syndromes. CONCLUSION Based on the evidence in the literature, the author concludes that there has been a type of paradigm shift described by philosopher of science, Thomas Kuhn, in the treatment of infants with trisomy 18 and 13. More parents are being offered and choosing technological interventions, including cardiac surgery. Future investigation of the question whether intervention improves outcome, including the quality of life, is crucial in addressing the unanswered questions in this dialogue. KEY POINTS · The conventional approach to the treatment of trisomy 18 and 13 has been to avoid interventions.. · There is a growing body of evidence that this traditional view of management is changing.. · Future investigation of whether intervention improves outcome is crucial in addressing the unanswered questions..

Survival outcomes of very low birth weight infants with trisomy 18. Am J Med Genet A 2021; 185:3459-3465. [PMID: 34415101 DOI: 10.1002/ajmg.a.62466] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/21/2021] [Revised: 06/28/2021] [Accepted: 08/05/2021] [Indexed: 11/08/2022]
Abstract
Trisomy 18 (T18) is one of the most commonly diagnosed aneuploidies leading to poor survival outcome. However, little is known about the dual risk of T18 and very low birth weight (VLBW, weighing <1500 g at birth). We aimed to investigate the survival and clinical features of VLBW infants with T18. In this observational cohort study, infants with T18 admitted to the neonatal intensive care unit in Kyushu University Hospital from 2000 to 2019 were eligible. Among 30 infants with T18 who were enrolled as study participants, 11 (37%) were born with VLBW. VLBW infants had lower gestational age (34.4 vs. 39.4 weeks, p < 0.01) and a higher incidence of esophageal atresia (64% vs. 11%, p < 0.01) than non-VLBW infants. The proportions of patients who underwent any surgery (55% vs. 5%, p < 0.01) and positive pressure ventilation (82% vs. 32%, p = 0.02) were higher in VLBW than non-VLBW infants. One-year overall survival rate (45% vs. 26%, p = 0.32 by log-rank test) did not differ between the two groups. In conclusion, being born at VLBW may not be fatal for infants with T18 undergoing active interventions.

Abstract
Most frequent chromosomal syndromes like Down, Patau, Edwards, Turner, and Williams affect the pediatric population in various ways, and congenital heart disease explains the altered quality of life they suffer. There is a lack of studies reviewing the cardiac anomalies in these syndromes, and the ones that exist are publications from past decades. We reviewed databases such as MEDLINE, LILACS, SCIELO, and Google Scholar, selecting the best possible evidence, and each chromosomal syndrome was investigated in relation to congenital heart disease, constituting five search groups. The article shows the characteristics of each heart disease described in the studies reviewed, the author, date of publication, country, and population studied, as well as a brief description of the frequency of the disease and its mortality. The results described in this review were contrasted with previous existing literature to verify if there was correspondence between the reported frequencies. The most frequent congenital heart diseases were atrioventricular septal defect (AVSD), ventricular septal defect (VSD), atrial septal defect (ASD), and persistent ductus arteriosus (PDA) in Down syndrome patients, PDA, ASD, and VSD in Patau syndrome patients, AVSD, PDA and valvular defects in Edwards syndrome, bicuspid aortic valve, aortic coarctation and aortic stenosis in Turner syndrome, and supravalvular aortic stenosis and pulmonary stenosis in Williams syndrome.

Anesthesia for children with complete trisomy 18 (Edwards syndrome): A cohort review of 84 anesthesia encounters in nine patients. Paediatr Anaesth 2021; 31:419-428. [PMID: 33644930 DOI: 10.1111/pan.14131] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/16/2020] [Revised: 12/30/2020] [Accepted: 01/05/2021] [Indexed: 11/28/2022]
Abstract
BACKGROUND Trisomy 18 or Edwards syndrome is the second most common aneuploidy with a prevalence between 1/3000 and 1/10 000 live births. The syndrome encompasses malformations of the central nervous, cardiac, respiratory, gastrointestinal, and genitourinary systems. Trisomy 18 carries a poor prognosis with 90% of patients not surviving beyond 1 year of age; however, the current trend toward more aggressive supportive care may prolong survival. The limited anesthesia literature highlights the abnormal airway anatomy but generally describes uneventful airway management and perioperative course. AIM Our goal was to review all anesthesia encounters recorded for eleven trisomy 18 patients treated at Children's Wisconsin during the study period to explore the frequency of anesthesia encounters and to improve our understanding of the perioperative risks. METHODS We performed a retrospective chart review of all patients with trisomy 18 who were treated at our institution between 2012 and 2017. Records were screened for anesthesia encounters, perioperative critical events and complications, enrollment in palliative care, code status, and time of death. RESULTS Eleven children were identified. Children were born between 2001 and 2016. Two children never required anesthesia care. Nine patients had a total of 84 anesthesia encounters for 121 surgical or diagnostic procedures or emergent intubations. Critical events and perioperative complications included difficult mask ventilation (n = 7), difficult intubation (n = 15), and mechanical or pharmacological cardiopulmonary resuscitation (n = 6). Five patients presented with difficult peripheral intravenous access. One patient died in the immediate postoperative period. On five occasions, patients required emergent intubation outside of the operating room. CONCLUSION Difficult airway management and respiratory compromise were critical concerns during the perioperative period in our patient population, and the inability to ventilate could lead to cardiorespiratory arrest. This case series provides a comprehensive, longitudinal view of complete trisomy 18 patients in the perioperative period and adds information for counseling families and care providers.

Abstract
BACKGROUND Surgical management has not been encouraged in patients with trisomy 18 (T18) and congenital heart diseases due to poor survival. This study aimed to investigate (1) the appropriateness of palliative surgeries followed by intracardiac repair (ICR) (i.e., two-stage ICR) for patients with a large ventricular septal defect (VSD) and T18, and (2) its impact on their long-term outcomes. METHODS Medical charts of patients with VSD and T18 who underwent two-stage ICR at the Japanese Red Cross Medical Center between January 2005 and December 2019 were retrospectively reviewed. Demographic data, timing, and types of palliative surgeries, information related to ICR, peri- and postoperative clinical information, postoperative survival, and cause of death were collected. The long-term prognosis of patients treated with two-stage ICR was compared with that of patients treated with primary ICR and palliative surgery without ICR. RESULTS Overall, 18 (2 male, 16 female) patients underwent two-stage ICR. Pulmonary artery banding was the initial palliative surgery in all patients after a median duration of 19.5 (range 6-194) days of life. The median age and the mean body weight at the time of ICR were 18.2 (7.6-50.7) months and 6.0 ± 1.0 kg, respectively. The mean pulmonary artery pressure and pulmonary vascular resistance index before ICR were 19.1 ± 7.3 mmHg and 3.4 ± 2.0 U m2, respectively. Overall, 17/18 (94%) patients were discharged after ICR. Fourteen (78%) patients were alive during data collection. None of the patients died of cardiac insufficiency, and the median duration of survival was 46.3 (14.3-186.4) months since birth. Most patients required cardiac medications rather than pulmonary vasodilators at the last follow-up. During the study period, three patients underwent primary ICR, and 46 underwent palliative surgery without ICR. Of those who underwent primary ICR, two died in the hospital on the first and 48th day following ICR, and the third died 179 days after the ICR. The Log-rank test revealed a significantly longer survival for the patients treated with two-stage ICR compared with those treated with palliative surgery without ICR (P = 0.003). CONCLUSION Two-stage ICR improves the long-term survival of patients with VSDs and T18. This safe surgical strategy can also prevent pulmonary hypertension in such patients.

Abstract
Trisomy 18 is the second most common aneuploidy syndromes in live born infants. It is associated with high mortality rates, estimated to be 75%-95% in the first year of life, as well as significant morbidity in survivors. The low survival is largely due to the high prevalence of severe congenital anomalies in infants with this diagnosis. However, interventions to repair or palliate those life-threatening anomalies are being performed at a higher rate for these infants, resulting in increased rates of survival beyond the first year of life. While it is well documented that trisomy 18 is associated with several cardiac malformations, these patients also have respiratory, neurological, neoplastic, genitourinary, abdominal, otolaryngologic, and orthopedic complications that can impact their quality of life. The goal of this review is to present a comprehensive description of complications in children with trisomy 18 to aid in the development of monitoring and treatment guidelines for the increasing number of providers who will be caring for these patients throughout their lives. Where the evidence is available, this review presents screening recommendations to allow for more rapid detection and documentation of these complications.

Abstract
INTRODUCTION Despite changes in prenatal diagnostic methods and perceptions regarding the prognosis of and treatment options for patients with trisomy 18 syndrome, data on the secular changes in patient survival are limited. This study aimed to investigate the survival pattern for such patients. METHODS To investigate the general patient survival patterns, we used data from the vital statistics database of deaths in Japan from 1975 to 2016. We described demographic factors, such as sex, gestational age at delivery, and surgical history, for patients whose primary cause of death was trisomy 18 syndrome. RESULTS The proportions of deaths within 24 h of birth (4.0% in 1975-1980 to 21.9% in 2011-2016) and at age ≥1 year (8.9% in 1975-1980 to 17.7% in 2011-2016) increased. The median survival time was higher for females, infants born after 37 weeks of gestation, and those who received surgical intervention. The median survival time tripled among patients who received surgical intervention (61.5 days in 1995-2005 to 182.5 days in 2006-2016), and the proportion of such patients increased (from 3.8% in 1995 to 24.1% of the entire affected population in 2016). DISCUSSION/CONCLUSION In Japan, the median survival time of infants with trisomy 18 increased over time, and the proportion of death within 24 h and at ≥1 year increased. Greater acknowledgement of the possible benefits of surgical intervention likely led to the increased provision of interventions and contributed to the increased survival time.

Abstract
Trisomy 18 is a chromosomal disease, caused by the presence of a supernumerary chromosome 18. Mortality among infants with trisomy 18 is high, secondary to lethal malformations associated with this syndrome. The purpose of this study was to describe the clinical and cytogenetic features of these patients, as well as the role of genetic counselling. We conducted a cross-sectional descriptive study over a 5-year period, from July 2015 to April 2019. The study involved, patients followed up in the Department of Medical Genetics at the University Hospital Center Ibn Rochd of Casablanca, having abnormalities suggestive of trisomy 18, then confirmed by cytogenetic study. The study enrolled 5 patients, 3 girls and 2 boys (female predominance; sex-ratio = 0,67) with clinically suspected Edward's syndrome, then confirmed by cytogenetic study. The mean age at diagnosis was 37.40 ± 23.98 days (9 days-2 months). Trisomy 18 was clinically suspected in two cases based on facial dysmorphism and malformative syndrome, a recognizable pattern of chromosomal abnormality. Two patients were hospitalized in the intensive care unit for decompensated heart failure associated with congenital heart disease, while one patient had neonatal respiratory distress associated with polymalformative syndrome at diagnosis. Cytogenetic study confirmed the diagnosis of free and homogeneous trisomy 18 in five patients, then genetic counselling was performed. The prevalence of trisomy 18 is variable. Global prevalence is estimated at 1/6000 live births, females are mostly affected. The diagnosis of trisomy 18 should be suspected at birth in newborns with typical craniofacial dysmorphism, arms lifted in supplication and permanent flexion of the fingers, the index finger overlapping the 3rd finger, the little finger overlapping the 4th finger. There are several malformations associated with trisomy 18. This syndrome should be also suspected in the antenatal period in patients with abnormalities on obstetric ultrasound. Moreover, survival is low and only one in 10 newborns reach the first year of life.

Abstract
OBJECTIVE We aim to clarify whether surgical interventions can contribute to improve the long-term outcomes among individuals with trisomy 18. METHODS We retrospectively studied 69 individuals with trisomy 18 admitted to 4 tertiary neonatal centers between 2003 and 2017. A cohort was divided into two groups: subjects with surgical interventions and conservative treatments. We compared the rates of survival and achieving homecare between the groups. RESULTS Gestational age and birth weight were 37 (27-43) weeks and 1,700 (822-2,546) g, respectively. There were 68 patients with congenital heart disease and 20 patients with digestive disease. Surgical interventions including cardiac and digestive surgery were provided in 41% of individuals. There was no difference in gestational age (p=0.30), birth weight (p=0.07), gender (p=0.30), and fetal diagnosis (p=0.87) between the groups. During the median follow up duration of 51 (2-178) months, overall survival rates in 6, 12 and 60 months were 57%, 43% and 12%, respectively. Survival to hospital discharge occurred in 23 patients, and the rates of achieving homecare in 1, 6, and 12 months are 1%, 18% and 30%, respectively. There was no significant difference in survival rate (p=0.26) but in the rate of achieving home care (p=0.02) between the groups. Cox hazard analysis revealed that prenatal diagnosis (hazard ratio 0.30, 95%CI: 0.13-0.75), cardiac surgery (hazard ratio 2.40, 95%CI:,1.03-5.55), and digestive surgery (hazard ratio 1.20, 95%CI: 1.25-3.90) were related to the rate of achieving homecare. CONCLUSION Aggressive surgical interventions contribute not to the long-term survival but to achieve homecare among individuals with trisomy 18.

Abstract
Trisomy 18 (T18) and trisomy 13 (T13) are major concerns in prenatal genetic testing due to their poor prognosis; very low birth weight (VLBW) is also a concern in neonatology. The aim of this study was to investigate the mortality and morbidity of VLBW infants diagnosed with T18/T13 in Japan, compared with those with no birth defects (BD-). Maternal and neonatal data were collected prospectively from infants weighing <1501 g and were admitted to centers of the Neonatal Research Network of Japan during 2003 to 2016. Among 60,136 infants, 563 and 60 was diagnosed with T18 and T13, respectively. Although the age of mothers of infants with T18/T13 was higher, the frequency of maternal complications was lower than those with BD-. With maternal and neonatal characteristic adjustments, T18/T13 had a higher incidence of each morbidity when compared with BD-. Mortality rates in the NICU were 70, 77, and 5.8% for T18, T13, and BD-, respectively, while the survival discharge rates of T18 and T13 were 29.5 and 23.3%, respectively, which was significantly higher than previous reports. This was the first nationwide survey for VLBW infants with T18/T13 in Japan; this novel data will be relevant and useful for prenatal genetic counseling and perinatal management. Although T18/T13 were considered to be fatal in the past, with proper epidemiological information, discussions with affected families, and compassionate patient care, the mortality rate of T18/T13 can be improved.

Abstract
BACKGROUND Families with a prenatal diagnosis of trisomy 13 or 18 are told many things, some true and some myths. They present with differing choices on how to proceed that may or may not be completely informed. PURPOSE To provide the prenatal counselor with a review of the pertinent obstetrical and neonatal outcome data and ethical discussion to help them in supporting families with the correct information for counseling. METHODS/SEARCH STRATEGY This article provides a review of the literature on facts and myths and provides reasonable outcome data to help families in decision making. FINDINGS/RESULTS These disorders comprise a heterogeneous group regarding presentation, outcomes, and parental goals. The authors maintain that there needs to be balanced decision-making between parents and providers for the appropriate care for the woman and her infant. IMPLICATIONS FOR PRACTICE Awareness of this literature can help ensure that prenatal and palliative care consultation incorporates the appropriate facts and parental values and in the end supports differing choices that can support the infant's interests.

Abstract
Trisomy 18 is a genetic disease resulting from an extra chromosome 18, characterized by a broad clinical spectrum, poor prognosis and low rates of survival. This is the case of a 12 year-old girl diagnosed with full trisomy 18, and multiple malformations, including Dandy-Walker Syndrome and congenital heart defects on long term survival. At nine months, a new echocardiogram showed a double outlet right ventricle, significant pulmonary stenosis, patent ductus arteriosus and ventricular septal defect. Cardiac surgery was performed at one year and seven months. Early surgical intervention and multidisciplinary follow-up may change the clinical outcome of the disease. Further studies are required to evaluate the benefit of invasive procedures such as cardiac surgery on survival of patients with trisomy 18.

Abstract
We present a case in which a fetal diagnosis of complex congenital heart disease and trisomy 18 led to a series of decisions for an infant who was critically ill. The parents wanted everything done. The surgeons believed that surgery would be futile. The parents publicized the case on social media, which led to publicity and pressure on the hospital. The case reveals the intersection of parental values, clinical judgments, ethics consultation, insurance company decisions about reimbursement, and social media publicity. Together, these factors complicate the already delicate ethical deliberations and decisions.

Abstract
Children with trisomy 18 that survive beyond the neonatal period have multiple congenital anomalies, neurodevelopmental disability, and high mortality rates. The experience of children with trisomy 18 who receive pediatric palliative care services is largely unknown. We conducted a retrospective review of children with trisomy 18 receiving pediatric palliative care services at both Boston Children's Hospital, USA and Great Ormond Street Hospital, UK from January 1, 2004 to January 1, 2015. Fifty-eight children with trisomy 18 were referred to pediatric palliative care, 38 in the United Kingdom, 20 in the United States. Median age at referral was 19 days (2-89) in the United Kingdom, and 25 days (1-463) in the United States. Median length of time being followed by pediatric palliative care was 32 days (1-1,637) in the United Kingdom and 67 days (3-2,442) in the United States. The only significant difference in the two cohorts (p = .001) was in likelihood of receiving cardiac surgical intervention-37% in the United States, 0% the United Kingdom. Children with trisomy 18 receive pediatric palliative care services, with variable age at referral and for a variable length of time. Further research is needed to understand the experience of children with trisomy 18 and their families receiving pediatric palliative care services.

Congenital Heart Surgical Admissions in Patients with Trisomy 13 and 18: Frequency, Morbidity, and Mortality. Pediatr Cardiol 2019; 40:595-601. [PMID: 30556105 DOI: 10.1007/s00246-018-2032-3] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/13/2018] [Accepted: 10/11/2018] [Indexed: 10/27/2022]
Abstract
Congenital heart defects are common among patients with trisomy 13 and 18; surgical repair has been controversial and rarely studied. We aimed to assess the frequency of cardiac surgery among admissions with trisomy 13 and 18, and evaluate their associations with resource use, complications, and mortality compared to admissions without these diagnoses. We evaluated congenital heart surgery admissions of ages < 18 years in the 1997, 2000, 2003, 2006, and 2009 Kids' Inpatient Database. Bivariate and multivariate analyses examined the adjusted association of trisomy 13 and 18 on resource use, complications, and inpatient death following congenital heart surgery. Among the 73,107 congenital heart surgery admissions, trisomy 13 represented 0.03% (n = 22) and trisomy 18 represented 0.08% (n = 58). Trisomy 13 and 18 admissions were longer; trisomy 13: 27 days vs. 8 days, p = 0.003; trisomy 18: 16 days vs. 8 days, p = 0.001. Hospital charges were higher for trisomy 13 and 18 admissions; trisomy 13: $160,890 vs. $87,007, p = 0.010; trisomy 18: $160,616 vs. $86,999, p < 0.001. Trisomy 18 had a higher complication rate: 52% vs. 34%, p < 0.006. For all cardiac surgery admissions, mortality was 4.5%; trisomy 13: 14% and trisomy 18: 12%. In multivariate analysis, trisomy 18 was an independent predictor of death: OR 4.16, 95% CI 1.35-12.82, p = 0.013. Patients with trisomy 13 and 18 represent 0.11% of pediatric congenital heart surgery admissions. These patients have a 2- to 3.4-fold longer hospital stay and double hospital charges. Patients with trisomy 18 have more complications and four times greater adjusted odds for inpatient death.

Mortality and Resource Use Following Cardiac Interventions in Children with Trisomy 13 and Trisomy 18 and Congenital Heart Disease. Pediatr Cardiol 2019; 40:349-356. [PMID: 30291384 DOI: 10.1007/s00246-018-2001-x] [Citation(s) in RCA: 20] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/05/2018] [Accepted: 09/28/2018] [Indexed: 11/24/2022]
Abstract
We sought to evaluate the mortality, risk factors for mortality, and resource utilization following cardiac interventions in trisomy 13 (T13) and 18 (T18) children. All T13 and T18 children who underwent a cardiac intervention from January 1999 to March 2015 were identified from the Pediatric Health Information System database. Data collected included demographics, type of congenital heart disease (CHD), cardiac interventions, comorbidities, length of stay (LOS), hospital charges, and deaths (within 30 days). Logistic regression analysis was used to determine factors associated with mortality. There were 49 (47% females) T13 and 140 (67% females) T18 subjects. The two cohorts were similar in distribution for race, geographic region, insurance type, and median household income. The most common CHD in both groups was a shunt lesion followed by conotruncal defects. Compared to T18, the T13 cohort had higher mortality (29% vs. 12%), tracheostomies (12% vs. 4%), gastrostomies (18% vs. 6%), and overall resource use (P < 0.05 for all). White race (OR 0.23, 95% CI 0.06-0.81) in T13 and older age (in weeks) at surgery in T18 (OR 0.75, 95% CI 0.64-0.86) were associated with lower mortality. A select group of T13 and T18 CHD patients can undergo successful cardiac interventions, albeit with a higher mortality and resource use. T13 patients have higher mortality and resource use compared to T18. In T13 and T18 patients, interventions for CHD may be an acceptable and ethical option following a careful individualized selection and counseling by a team of experts.

Abstract
OBJECTIVE We assessed survival, hospital length of stay (LOS), and costs of medical care for infants with lethal congenital malformations, and also examined the relationship between medical and surgical therapies and survival. STUDY DESIGN Retrospective cohort study including infants born 1998-2009 with lethal congenital malformations, identified using a longitudinally linked maternal/infant database. RESULTS The cohort included 786 infants: trisomy 18 (T18, n = 350), trisomy 13 (T13, n = 206), anencephaly (n = 125), bilateral renal agenesis (n = 53), thanatophoric dysplasia/achondrogenesis/lethal osteogenesis imperfecta (n = 38), and infants > 1 of the birth defects (n = 14). Compared to infants without birth defects, infants with T18, T13, bilateral renal agenesis, and skeletal dysplasias had longer survival rates, higher inpatient medical costs, and longer LOS. CONCLUSION Care practices and survival have changed over time for infants with T18, T13, bilateral renal agenesis, and skeletal dysplasias. This information will be useful for clinicians in counseling families and in shaping goals of care prenatally and postnatally.

Clinical courses of children with trisomy 13 receiving intensive neonatal and pediatric treatment. Am J Med Genet A 2018; 176:1941-1949.

Abstract
Management of children with trisomy 13 (T13) is controversial because of a paucity of evidence of the natural history, especially focusing on efficacy of treatment. There has been no report regarding natural history of children with T13 receiving intensive neonatal and pediatric treatment without cardiac surgery, although several reports have suggested efficacy of cardiac surgery. To describe the detailed and comprehensive natural history of children with T13 receiving intensive neonatal and pediatric treatment without cardiac surgery, we reviewed clinical information of 24 children with full T13 (15 boys, 9 girls) who were admitted to Nagano Children's Hospital from 1994 to 2016. Intensive neonatal and pediatric treatment without cardiac surgery was provided through careful discussion with the parents. We detailed accurate frequencies of complications, survival, underlying factors and the final modes of death, and psychomotor development of survivors. Unpublished complications including aortopulmonary window, pulmonary-ductus-descending aorta-trunk, biliary system abnormalities, eosinophilic enteritis, and neuroblastoma were described. Accurate frequencies of congenital heart defects (92%) and laryngomalacia and/or tracheomalacia (42%) were determined. The median survival time was 451 days and the 1-year survival rate was 54%. The major underlying factor associated with death was congenital heart defects and heart failure (63%) and the major final mode of death was heart failure (50%). Long-term survivors appeared to show slow but constant psychomotor development. Intensive neonatal and pediatric treatment without cardiac surgery for children with T13 is efficient for survival and psychomotor development, and could be a reasonable choice for parents having fetuses or children with T13.

Abstract
OBJECTIVES To evaluate parental decisions following a prenatal diagnosis of trisomy 13 (T13) or trisomy 18 (T18), prenatal counseling received, and pregnancy outcomes. STUDY DESIGN Single-center, retrospective cohort study of families with a prenatal diagnosis of T13 or T18 from 2000 to 2016. RESULTS Out of 152 pregnancies, 55% were terminated. Twenty percent chose induction with palliative care, 20% chose expectant management, 2% chose full interventions, and 3% were lost to follow-up. Counseling was based on initial parental goals, but most women were given options besides termination. Women who chose expectant management had a live birth in 50% of the cases. Women who chose neonatal interventions had a live birth in 100% of the cases, but there were no long-term survivors. CONCLUSIONS The majority of women who continue their pregnancy after a fetal diagnosis of T13 or T18 desire expectant management with palliative care. A live birth can be expected at least half of the time.

Abstract
Spontaneous regression of severe aortic coarctation with ductus dependency has not been reported. We experienced a case of trisomy 18 with spontaneous regression of severe aortic coarctation complicated by ventricular septal defect and patent ductus arteriosus. The aortic isthmus diameter was 1.2 mm at birth. After 5 months, it increased to 4.5 mm, and the shape of the isthmus was fully normalised.

Abstract
Edwards’ syndrome also known as trisomy 18 is a congenital disorder associated with cardiovascular issues including ventricular septal defect (VSD), atrial septal defect (ASD) and patent duct arteriosus (PDA). An emergency colostomy was performed on a neonate born with an imperforate anus. Pre-operative transthoracic echocardiography showed presence of VSD, a patent foramen ovale (PFO) or ASD. Even though the baby had a good general condition and optimal peripheral oxygen saturation (SpO2), during positive pressure ventilation, she suffered severe hypoxia (50% SpO2). The cause of the hypoxia was thought to be the right-left shunt and so during a second attempt at anaesthesia a vasopressor (noradrenaline 0.03 µg/kg/min) was infused to increase systemic vascular resistance. Thereafter, SpO2 increased to 80–90% and the surgery was completed. The baby recovered without any neurological complications. Genetic testing post-partum showed she had Edwards’ syndrome.

Abstract
OBJECTIVE To describe neonatal intensive care unit (NICU) medical interventions and NICU mortality by birth weight and major anomaly types for infants with trisomy 13 (T13) or 18 (T18). STUDY DESIGN Retrospective cohort analysis of infants with T13 or T18 from 2005 to 2012 in the Pediatrix Medical Group. We classified infants into three groups by associated anomaly type: neonatal surgical, non-neonatal surgical and minor. Outcomes were NICU medical interventions and mortality. RESULTS 841 infants were included from 186 NICUs. NICU mortality varied widely by anomaly type and birth weight, from 70% of infants <1500 g with neonatal surgical anomalies to 31% of infants ⩾2500 g with minor anomalies. Infants ⩾1500 g without a neonatal surgical anomaly comprised 66% of infants admitted to the NICU; they had the lowest rates of NICU medical interventions and NICU mortality. CONCLUSIONS Risk stratification by anomaly type and birth weight may help provide more accurate family counseling for infants with T13 and T18.

Abstract
Perinatal palliative care programs seek to support parents expecting a baby diagnosed with a serious medical condition. Clinicians have increasingly recognized the importance of parental perspectives on the medical care mothers and their fetuses and live-born children receive, especially regarding factors influencing individual choices and knowledge of the medical community. We describe, using literature on trisomy 13 and trisomy 18, how information shared between parents and providers can improve perinatal counseling and family support.

Abstract
BACKGROUND Surgical repair for cardiac lesions has rarely been offered to patients with trisomy 18 because of their very short lifespans. We investigated the effectiveness of cardiac surgery in patients with trisomy 18. Patients and methods We performed a retrospective analysis of 20 consecutive patients with trisomy 18 and congenital cardiac anomalies who were evaluated between August, 2003 and July, 2013. All patients developed respiratory or cardiac failure due to excessive pulmonary blood flow. Patients were divided into two subgroups: one treated surgically (surgical group, n=10) and one treated without surgery (conservative group, n=10), primarily to compare the duration of survival between the groups. RESULTS All the patients in the surgical group underwent cardiac surgery with pulmonary artery banding, including patent ductus arteriosus ligation in nine patients and coarctation repair in one. The duration of survival was significantly longer in the surgical group than in the conservative group (495.4±512.6 versus 93.1±76.2 days, respectively; p=0.03). A Cox proportional hazard model found cardiac surgery to be a significant predictor of survival time (risk ratio of 0.12, 95% confidence interval 0.016-0.63; p=0.01). CONCLUSIONS Cardiac surgery was effective in prolonging survival by managing high pulmonary blood flow; however, the indication for surgery should be carefully considered on a case-by-case basis, because the risk of sudden death remains even after surgery. Patients' families should be provided with sufficient information to make decisions that will optimise the quality of life for both patients and their families.
