Abstract
Alagille syndrome (ALGS) is a complex rare genetic disorder that involves multiple organ systems and is historically regarded as a disease of childhood. Since it is inherited in an autosomal dominant manner in 40% of patients, it carries many implications for genetic counselling of patients and screening of family members. In addition, the considerable variable expression and absence of a clear genotype-phenotype correlation, results in a diverse range of clinical manifestations, even in affected individuals within the same family. With recent therapeutic advancements in cholestasis treatment and the improved survival rates with liver transplantation (LT), many patients with ALGS survive into adulthood. Although LT is curative for liver disease secondary to ALGS, complications secondary to extrahepatic involvement remain problematic lifelong. This review is aimed at providing a comprehensive review of ALGS to adult clinicians who will take over the medical care of these patients following transition, with particular focus on certain aspects of the condition that require lifelong surveillance. We also provide a diagnostic framework for adult patients with suspected ALGS and highlight key aspects to consider when determining eligibility for LT in patients with this syndrome.

Abstract
OBJECTIVES This study aims to report liver transplantation (LT) outcomes and cardiac disease manifestations in children with Alagille Syndrome (ALGS) in a contemporary cohort. METHODS This project used a novel linkage between the Scientific Registry of Transplant Recipients and Pediatric Health Information System databases. All children ≤21 years undergoing a first LT were identified (2002-2018). The presence of ALGS was identified using Scientific Registry of Transplant Recipients diagnosis coding. Subjects with ALGS were age-matched 1:2 to LT recipients with biliary atresia (BA). The Kaplan-Meier method and log-rank test were used to compare patient and graft survival between groups. RESULTS A total of 156 LT recipients with ALGS were identified and matched to a control group of 312 LT recipients with BA. Children with ALGS were more likely to have an associated diagnosis of congenital heart disease (80.7% vs 16.4%; P = 0.001) compared with children with BA with 40 (25.6%) children with AGS requiring cardiac intervention (catheter or surgical) either before or after LT. Those patients with ALGS had a higher creatinine, laboratory MELD, and PELD scores before LT. No difference was observed regarding patient or graft survival between children with ALGS and children with BA ( P = 0.08 and P = 0.27, respectively). CONCLUSIONS Despite increased rate of congenital heart defects and cardiac interventions, higher creatinine, and higher laboratory MELD/PELD scores at time of transplant, this study demonstrates that there is no difference in either patient or graft survival between patients with ALGS and BA.

Abstract
Alagille syndrome, caused by mutations in the gene encoding Jagged1 (JAG1), a ligand in the Notch signaling pathway, is an autosomal dominant disorder with developmental abnormalities affecting the liver, heart, eyes, face and skeleton. The aim of the present study is try to disclose the clinical features, management and outcomes of pulmonary artery stenosis associated with Alagille syndrome. By comprehensive literature retrieval, 38 articles involving 401 patients were recruited for this study. The pertinent variables closely related to pulmonary artery stenosis in patients with Alagille syndrome were comprehensively analyzed by following the PRISMA guidelines. The management of pulmonary artery pathologies, especially a severe type of pulmonary artery stenosis in Alagille syndrome, is a concerned matter. Publications of literature retrieval of recent 3 decades were the study material of this article. The pulmonary artery pathologies, especially the severe type of pulmonary artery stenosis in Alagille syndrome, warrant surgical or interventional treatments. After the procedures, the right ventricular to left ventricular pressure ratio was reduced by 25%. There were no intergroup differences in terms of recovery, reintervention and mortality rates between interventionally and surgically treated patients. Transcatheter treatment is preferable due to less trauma. Surgical treatment of pulmonary artery stenosis can be performed currently with intracardiac defect repair.

Abstract
Alagille syndrome (ALGS) is an autosomal dominant disorder characterized by involvement of various organ systems. It predominantly affects the liver, skeleton, heart, kidneys, eyes and major blood vessels. With myriads of presentations across different age groups, ALGS is usually suspected in infants presenting with high gamma glutamyl transpeptidase cholestasis and/or congenital heart disease. In children it may present with decompensated cirrhosis, intellectual disability or short stature, and in adults vascular events like stroke or ruptured berry aneurysm are more commonly noted. Liver transplantation (LT) is indicated in children with cholestasis progressing to cirrhosis with decompensation. Other indications for LT include intractable pruritus, recurrent fractures, hepatocellular carcinoma and disfiguring xanthomas. Due to an increased risk of renal impairment noted in ALGS, these patients would require optimized renal sparing immunosuppression in the post-transplant period. As the systemic manifestations of ALGS are protean and a wider spectrum is being increasingly elucidated, a multidisciplinary team needs to be involved in managing these patients. Moreover, many basic-science and clinical questions especially with regard to its presentation and management remain unanswered. The aim of this review is to provide updated insights into the management of the multi-system involvement of ALGS.

Abstract
AIMS AND BACKGROUND Ophthalmic abnormalities are amongst the 5 major criteria required for a diagnosis of Alagille syndrome (ALGS), of which embryotoxon, pseudopapilledema, and hypopigmented retinopathy are the most common. Papilledema with or without intracranial hypertension (ICHT) is rarely described. We report 9 pediatric cases of ALGS with bilateral papilledema, 5 of which were diagnosed with ICHT. METHODS The ophthalmic data from 85 patients with clinically and/or genetically (n = 37) proven ALGS were reviewed. The study inclusion criteria were a positive diagnosis of ALGS and availability of ophthalmic follow-up data. Ophthalmic data from 40 patients after liver transplantation (LT) for other indications were also analyzed. RESULTS Nine (13.0%) of the 69 patients meeting the inclusion criteria had papilledema. The neurological and neuroimaging results in all 9 patients were normal. These 9 patients were categorized into 4 groups: a nontransplant group (n = 1), a group with pretransplant papilledema persistent after LT (n = 2), a group with papilledema occurring after LT with spontaneous resolution (n = 1), and a group with papilledema and signs of ICHT after LT (n = 5). The patients with ICHT were treated with steroids alone (n = 1) or with acetazolamide (n = 4). A ventriculoperitoneal shunt was placed in 2 of the 5 cases because of progressive visual loss. Pseudopapilledema was present in 10 additional patients (14.5%, 10/69). One (2.5%) of the 40 patients without ALGS developed papilledema after LT. CONCLUSIONS True ICHT may be underdiagnosed in patients with ALGS. Our findings underscore the need for close ophthalmic follow-up before and after LT in these patients.

Abstract
There is close interaction between the functions of the liver and heart affecting the presentation, diagnosis, and outcome of acute and chronic cardiac and liver disease. Conditions affecting both organ systems should be considered when proposing transplantation because the interaction between cardiac disease and liver disease has implications for diagnosis, management, selection for transplantation, and, ultimately, for longterm outcomes after liver transplantation (LT). The combination of cardiac and liver disease is well recognized in adults but is less appreciated in pediatric patients. The focus of this review is to describe conditions affecting both the liver and heart and how they affect selection and management of LT in the pediatric population.

Abstract
Severe pulmonary hypertension is a contraindication for liver transplantation owing to high mortality. However, decision-making regarding the treatment approach for patients with bilateral peripheral pulmonary artery stenosis, typically complicated by elevated main pulmonary artery and right ventricle pressures, can be challenging. Here, we report successful living donor liver transplantation after bilateral pulmonary artery stent implantation in a patient with Alagille syndrome, severe bilateral peripheral pulmonary artery stenosis, and extremely high main pulmonary artery and right ventricle pressures.

Abstract
Advances in surgical techniques and follow-up of patients with complex congenital heart disease who were corrected in childhood increasingly survive to adolescence or adulthood. Increasingly anesthesiologists encounter these cases for major noncardiac surgery, including orthotopic liver transplantation (OLT) wherein there is an augmented risk of significant perioperative hemodynamic instability. We performed a successful OLT in a 12-year-old boy with end-stage cryptogenetic liver fibrosis and hepatopulmonary syndrome who was born with a double outflow right ventricle, pulmonary atresia, and pulmonary artery hypoplasia corrected at the age of 1 month. By the time he was considered for OLT his altered pulmonary valve apparatus resulted in severe pulmonary regurgitation, dilated right atrium and ventricle, and elevated right heart pressures. After a temporarily successful angioplasty he was at first placed on the waiting list, then removed, and finally relisted following implantation of a prosthetic pulmonary valve that resulted in significant reduction of right heart pressures.

Abstract
Cholestatic liver diseases include a group of diverse disorders with different epidemiology, pathophysiology, clinical course, and prognosis. Despite significant advances in the clinical care of patients with cholestatic liver diseases, liver transplant (LT) remains the only definitive therapy for end-stage liver disease, regardless of the underlying cause. As per the United Network for Organ Sharing database, the rate of cadaveric LT for cholestatic liver disease was 18% in 1991, 10% in 2000, and 7.8% in 2008. This review summarizes the available evidence on various common and rare cholestatic liver diseases, disease-specific issues, and pertinent aspects of LT.

Abstract
BACKGROUND Alagille syndrome is a multi-system developmental disorder associated with paucity of interlobular bile ducts and cholestasis, rarely associated with hepatocellular carcinoma. Associated syndromic co-morbidities may complicate surgical management. As such, we herein review the modern management of a large hepatocellular carcinoma in an adult patient with Alagille syndrome and review the literature of adult Alagille patients with hepatocellular carcinoma. CASE PRESENTATION A 29-year-old woman with a history of Alagille syndrome was referred with biopsy-proven 12 × 8 cm hepatocellular carcinoma replacing her right liver. Biopsy of the contralateral liver demonstrated findings consistent with Alagille syndrome, but no underlying cirrhosis. CT volumetrics demonstrated a future liver remnant of 40%. Extensive hematologic and cardiac work-up was performed pre-operatively, given the syndrome's associated bleeding dyscrasias and cardiac abnormalities. The patient underwent a margin-negative right hepatectomy using the "hanging" technique through a thoracoabdominal approach. The patient developed a transient hyperbilirubinemia but no hepatic insufficiency and did well post-operatively. CONCLUSION Since Alagille syndrome affects multiple organ systems, preoperative evaluation of cardiac, hematologic, and hepatic function should be considered. This case illustrates the peri-operative management of an Alagille patient, and highlights several key technical points that contributed to a successful resection.

Abstract
Alagille syndrome is a multisystem disorder in which progressive liver disease with persistent cholestasis and dramatic pruritus often warrant consideration for liver transplantation. The most important part of the transplant assessment is evaluation of the cardiac and renal involvement. Preoperatively, cardiac performance often must be tested with dynamic stress tests, mimicking hemodynamic changes during liver transplant. Many aspects of the syndrome including cholestasis, pruritus, and hypercholesterolemia improve posttransplant, but short stature is rarely significantly affected. One- and 5-year patient and graft survival after liver transplant is comparable to other elective indications, but effects of long-term immunosuppressants on evolution of other components of the syndrome, including vascular, bone, and renal disease, remain largely unknown.

Abstract
BACKGROUND The occurrence of congenital heart disease (CHD) with congenital biliary disease is uncommon. Our aim is to present our experience in living donor liver transplantation (LDLT) as treatment for end-stage liver disease (ESLD) in children with CHD. METHODS A review of transplant records from June 1994 to December 2004 was performed. Twenty-three LDLT (13 males, 10 females) recipients were diagnosed to have both CHD and ESLD. RESULTS CHD diagnoses were made preoperatively using transthoracic two-dimensional color flow Doppler echocardiography. The mean age was 22.3 months. There were 20 (87%) biliary atresia, two (9%) neonatal hepatitis, and one (4%) glycogen storage disease patients. Isolated CHD associated with ESLD included atrial septal defect (11, 48%), pulmonary stenosis (including 2 Alagille syndrome; 4, 17%), patent foramen ovale (4, 17%), ventricular septal defect (1, 4%), and mitral valve prolapse (1, 4%). Complex CHD included atrial septal defect + patent ductus arteriosus + patent foramen ovale (1, 4%), and atrial septal defect + pulmonary stenosis (1, 4%). The median Child's and Pediatric End-stage Liver Disease scores were 9, and 17, respectively. In all, 70% presented with varying degrees of pulmonary congestion pretransplant. There were no perioperative cardiac complications. Posttransplant, the patent foramen ovale in four recipients and atrial septal defect in four recipients closed spontaneously; and two recipients with pulmonary stenosis had their stenoses resolved spontaneously. The overall rejection rate was 17%. There was no mortality. The overall recipient and graft survivals at 1 and 5 years were both 100%. CONCLUSION LDLT is a safe procedure in a select group of ESLD patients with CHD.

Abstract
Little is known about the safety of LRLTx in children with end stage liver disease associated with congenital cardiac anomalies. We report the successful LRLTx in a case with extrahepatic biliary atresia associated with cTGA, VSD, and PS. Preoperative cardiac function was evaluated by cardiac echogram and cardiac catheterization. The recipient's cardiac function was preserved (EF; 54%); however, because of the left to right shunt disease, oxygen saturation was 91%. At operation, carbon dioxide insufflation into the abdominal cavity was attempted to prevent sudden air embolism. Hemodynamic variables were stabilized during partial clamping of the inferior vena cava, and at reperfusion of the portal vein. However, a sudden decrease in blood oxygenation was observed during hepatico-jejunostomy, which was easily normalized by graft mobilization. Post-operatively, neither heart failure nor cerebral infarction because of air embolism was observed. In conclusion, together with preserved cardiac function and carbon dioxide insufflation, LRLTx was successful. Further studies are required to establish the algorithm for the strategy of treating both congenital cardiac anomalies and liver failure.

Abstract
BACKGROUND Cardiac repair for congenital heart disease in children awaiting liver transplantation presents unique therapeutic challenges and dilemmas. We tested the hypothesis that operations in these children requiring cardiopulmonary bypass (CPB) were not associated with prohibitive morbidity and mortality. METHODS Over the last 10 years (1994-2004), five infants were identified in our database with end-stage liver disease and awaiting liver transplantation that required cardiac surgery. Primary end point for the study was mortality. Secondary end points included morbidity and time to liver transplantation. The new pediatric end-stage liver disease (PELD) model was used to score liver disease severity. RESULTS Three boys and two girls with mean age of 8.6 months (range, 1.5-21 months) and mean PELD of 18.0 (range, 10-29) required CPB for repair. The only early mortality in the series occurred after cardiac arrest during creation of a central shunt. The child expired two days later despite extracorporeal membrane oxygenation support. The patient had important myocardial hypertrophy. All other patients survived and underwent successful liver transplantation. CONCLUSIONS Children with significant congenital heart disease awaiting liver transplantation can undergo safe cardiac repair with judicious perioperative support thereby reducing the risks of subsequent liver transplantation.

Abstract
Alagille syndrome (AS) is a dominantly inherited, multisystem disorder involving the liver, heart, eyes, face, and skeleton. From October 1997 through July 2004, 260 pediatric orthotopic liver transplantations (OLTx) were performed in 231 patients. This report describes 21 patients of median age 1.95 years (range, 0.7-16.7) who had alagille syndrome. We present the technical features of the OLTx, incidence and type of complications, medical conditions related to the syndrome, need for retransplantation, as well as patient and graft survival rates. A split liver technique was used in 16 patients (76%) who received a left lateral segment (LLS) graft whereas 7 patients (33%) received a whole liver. Only cadaveric donors were used. The major surgical complications requiring reintervention in 11 patients (52%) included biliary problems (19%) and vascular complications (17%). One case of hepatic artery thrombosis required retransplantation. Three recipients (14%) died. All other patients are alive with an actuarial survival rate of 90% at 1 year and 80% at 5 years. The actuarial graft survival rate is 85% at 1 year and 75% at 5 years. Patients with AS, despite the associated cardiovascular anomalies, can be treated successfully by a combined approach between cardiologist, radiologist, cardiothoracic, and liver transplant surgeons. With careful planning and operative management, the results are comparable with those obtained with other more common cholestatic diseases.

Abstract
The natural history of most liver diseases requiring liver replacement in children is well known, and the potential of this therapy has been ascertained regarding life expectancy, which currently exceeds 90% in the long term. The timing of liver transplantation must be anticipated, to reduce the physical, psychological and mental impact of chronic liver diseases. Several studies show evidence that the best long-term results with regard to patient and graft survival are obtained with grafts procured from relatively young donors. Since the shortage of post-mortem liver donors will most likely worsen, further development of live, related-donor transplantation can be expected. The main progress to come will concern immunosuppression, taking advantage of the immunological privilege of the liver. Protocols are under development for induction of operational tolerance.

Abstract
Peripheral pulmonary artery stenosis challenges therapeutic algorithms for the management of congenital heart malformations. Surgical repair of the proximal pulmonary artery lesion remains with a high recurrence rate while the distal lesions are difficult to access. With the development of transcatheter interventional strategies in the early 1980s, a number of transcatheter treatment options became available. In this review, we summarize the current state of the art for interventional strategies in the management of peripheral pulmonary artery stenosis.

Abstract
The history of pediatric liver transplantation cannot be dissociated from one man, Thomas E. Starzl, whose pioneer efforts contributed more than anyone else to what has become a routinely successful clinical procedure. During the pre-cyclosporine era, the pediatric experience was confined nearly exclusively in Denver: first attempt in 1963, first success with survival beyond one year in 1967, cumulative experience with 84 pediatric cases in the pre-cyclosporine era (1967-1979) with a 2-year patient survival rate of 30%. The stampede for the development of other liver transplant centers came with the introduction of cyclosporine in the early eighties. Besides Pittsburgh, seven centers (Brussels, Cambridge and Hanover in Europe; Boston, Dallas, UCLA, Minneapolis in USA) had performed up to 1986 at least 20 pediatric liver transplants each with a long-term (>1 year) patient survival rate ranging between 57% and 83%. At the moment, a long-term patient survival rate in excess of 90% in elective patients -including infants - is commonly obtained in experienced centers. The shortage of size matched liver donors which was responsible for a high death rate on the cadaveric waiting list stimulated the development or technical innovations based on the segmental anatomy of the liver: reduced ('cutdown') liver graft, split graft and living liver transplantation. Challenging technical aspects in the recipient have been solved in order to reduce the incidence of surgical complications like outflow obstruction, arterial and portal thrombosis, and biliary problems. The indications of liver transplantation have been refined; regarding biliary atresia, which is the most frequent indication, a consensus has developed to propose a sequential strategy with a single attempt at hepatoportoenterostomy followed, when it fails, by liver transplantation. Some contra-indications accepted in the past are not currently valid with better understanding of the pathophysiology and/or increased clinical experience; such is the case of the hepatopulmonary syndrome. A major progress in preoperative management has been achieved through a multidisciplinary approach, particularly regarding nutrition and control of portal hypertension-related bleeding and ascites. Perioperatively, liver transplantation has derived benefit from the expertise of anesthetists managing babies with serious conditions and increased experience of the transplant surgeons regarding the knowledge of all the technical modalities, good strategy, technical skills and meticulous control of bleeding. It is well-recognized that children require more immunosuppression than adults. As in adults, the first breakthrough came with the introduction of cyclosporine which more than doubled the one-year patient survival rate. The next advance during the last decade was afforded by FK 506 - Tacrolimus which allows steroid withdrawal with the first year post-transplant in most patients. Besides its efficacy in reducing the incidence of rejection and absence of cosmetic side-effects, the steroid-sparing effect of Tacrolimus is of utmost importance to preserve the growth potential of children. The use of OKT-3 both for induction and treatment of rejection has been abandoned nearly universally because its use, cumulated with other immunosuppressants, resulted in a high incidence of lymphoproliferative disorder. In contrast, anti-IL2-receptor monoclonal antibodies, will most likely gain an increasing place in induction, with the availability of chimeric or humanized preparations. The side-effects of immunosuppression can endanger both the quality of life and the life expectancy; they are a special source of concern in pediatric recipients whose survival can be expected to be more than a few decades. Children would benefit most from the development of a marker able to identify the patients who have developed graft acceptance, allowing complete wearing of immunosuppression. Also they would benefit most from research protocols of tolerance induction. Since the vast majority of liver-transplanted children will have a reasonably normal life expectancy, the focus should be switched to their long-term rehabilitation and the assessment of their quality of life when they reach adulthood.
