Abstract
BACKGROUND CHDs are one of the most frequent congenital malformations, affecting one in hundred live births. In total, 70% will require treatment in the first year of life, but over 90% of cases in low- and middle-income countries receive no treatment or suboptimal treatment. As a result, CHDs are responsible for 66% of preventable deaths due to congenital malformations in low- and middle-income countries. This study examines the unmet need of congenital cardiac care around the world based on the global burden of disease. MATERIALS AND METHODS CHD morbidity and mortality data for 2006, 2011, and 2016 were collected from the Institute for Health Metrics and Evaluation Global Burden of Disease Results Tool and analysed longitudinally to assess trends in excess morbidity and mortality. RESULTS Between 2006 and 2016, a 20.7% reduction in excess disability-adjusted life years and 20.6% reduction in excess deaths due to CHDs were observed for children under 15. In 2016, excess global morbidity and mortality due to CHDs remained high with 14,788,418.7 disability-adjusted life years and 171,761.8 paediatric deaths, respectively. In total, 90.2% of disability-adjusted life years and 91.2% of deaths were considered excess. CONCLUSION This study illustrates the unmet need of congenital cardiac care around the world. Progress has been made to reduce morbidity and mortality due to CHDs but remains high and largely treatable around the world. Limited academic attention for global paediatric cardiac care magnifies the lack of progress in this area.

Abstract
BACKGROUND There is a paucity of literature regarding the association of high oncotic priming solutions for pediatric cardiopulmonary bypass (CPB) and outcomes, and no consensus exists regarding the composition of optimal CPB priming solution. This study aimed to examine the impact of high oncotic pressure priming by the addition of 20% human albumin on outcomes. METHODS Double-blinded, randomized controlled study was done in the pediatric cardiac intensive care unit of a tertiary care hospital. Consecutive children with congenital heart diseases admitted for open-heart surgery were randomized into two groups, where the study group received an additional 20% albumin to conventional blood prime before CPB initiation. RESULTS We enrolled 39 children in the high oncotic prime (added albumin) group and 37 children in the conventional prime group. In the first 24-hour postoperative period, children in the albumin group had significantly lower occurrence of hypotension (28.2% vs 54%, P = .02), requirement of fluid boluses (25.6% vs 54%, P = .006), and lactate clearance time (6 vs 9 hours, P < .001). Albumin group also had significantly higher platelet count (×103/µL) at 24 hours (112 vs 91, P = .02). There was no significant difference in intra-CPB hemodynamic parameters and incidence of acute kidney injury. In subgroup analysis based on risk category, significantly decreased intensive care unit stay (4 vs 5 days, P = .04) and hospital stay (5 vs 7 days, P = .002) were found in the albumin group in low-risk category. CONCLUSION High oncotic pressure CPB prime using albumin addition might be beneficial over conventional blood prime, and our study does provide a rationale for further studies.

Abstract
OBJECTIVE: The effects of Vasoactive-Ventilation-Renal (VVR) score on the evaluation of pediatric heart surgery results were investigated in this study. METHODS: This retrospective study included children younger than 18 years of age who were operated for congenital heart disease between was July 1st- December 31st 2018. Patients who needed ECMO support at the first postoperative 72 hours were not included in the study group. The postoperative initial, 24th and 48th-hour Vasoactive-Inotrope Score (VIS) and VVR scores of all patients were calculated in the intensive care unit (ICU). The effects of these scores on lengthy ICU duration (PCILOS, duration more than the upper 25th percentile) and to the hospital mortality (before 30 days) were evaluated. RESULTS: There were 340 patients in this study. The median age was 12 months (1 day-18 years), and the median weight was 7 kg (2.5 -82 kg). 18% of the patients had single ventricle physiology. Total correction was performed in 88% of the patients. Median RACHS 1 score was 2 (1–6). PCILOS was>112 hours and total mortality was 4%. The 0th hour VVR ICU c index=0.73 (CI: 0.70–0.77), mortality c index=0.77 (CI: 0.69–0.85). VVR at 24th hour ICU c index=0.75 (CI: 0.71–0.79), mortality c index=0.86 (CI: 0.81–0.91). VVR at 48th-hour ICU c index=0.87 (CI: 0.82–0.92), mortality c index=0.92 (CI: 0.87–0.97). The VVR score at 48th-hour was a strong indicator for the prediction of both LICU duration (odds ratio [OR]: –1.44; p=0.001) and hospital mortality (OR: –1.28; p=0.001). CONCLUSION: The postoperative VVR score can be a strong determinant for the prediction of early clinical results in congenital heart disease patients, which were considerably a heterogeneous group.

Abstract
OBJECTIVES Early extubation following pediatric cardiac surgery is common, but debate exists whether location affects outcome, with some centers performing routine early extubations in the operating room (odds ratio) and others in the cardiac ICU. We aimed to define early extubation practice variation across hospitals and assess impact of location on hospital length-of-stay and other outcomes. DESIGN Secondary analysis of the Pediatric Cardiac Critical Care Consortium registry. SETTING Twenty-eight Pediatric Cardiac Critical Care Consortium hospitals. PATIENTS Patients undergoing Society of Thoracic Surgeons-European Association for Cardio-Thoracic Surgery mortality category 1-3 operations between August 2014 and February 2018. INTERVENTIONS None. MEASUREMENTS AND MAIN RESULTS We defined early extubation as extubation less than 6 hours after postoperative admission. Hospitals were categorized based on the proportion of their early extubation patients who underwent an odds ratio extubation. Categories included low- (< 50% of early extubation, n = 12), medium- (50%-90%, n = 8), or high- (> 90%, n = 8) frequency odds ratio early extubation centers. The primary outcome of interest was postoperative hospital length-of-stay. We analyzed 16,594 operations (9,143 early extubation, 55%). Rates of early extubation ranged from 16% to 100% across hospitals. Odds ratio early extubation rates varied from 16% to 99%. Patient characteristics were similar across hospital odds ratio early extubation categories. Early extubation rates paralleled the hospital odds ratio early extubation rates-77% patients underwent early extubation at high-frequency odds ratio extubation centers compared with 39% at low-frequency odds ratio extubation centers (p < 0.001). High- and low-frequency odds ratio early extubation hospitals had similar length-of-stay, cardiac arrest rates, and low mortality. However, high-frequency odds ratio early extubation hospitals used more noninvasive ventilation than low-frequency hospitals (15% vs. 9%; p < 0.01), but had fewer extubation failures (3.6% vs. 4.5%; p = 0.02). CONCLUSIONS Considerable variability exists in early extubation practices after low- and moderate-complexity pediatric cardiac surgery. In this patient population, hospital length-of-stay did not differ significantly between centers with different early extubation strategies based on location or frequency.

Abstract
BACKGROUND Intraoperative vascular imaging is a useful tool to evaluate coronary ostia in congenital heart patients with suboptimal preoperative imaging findings. Additionally, vascular imaging has potential value for visualization of the ascending aortic intima media thickness (IMT) in certain clinical scenarios. This study sought to evaluate the feasibility of intraoperative vascular imaging of coronary ostia and IMT during congenital heart surgery. METHODS We describe the technique for performance of intraoperative vascular imaging by a pediatric cardiologist using a high-resolution linear sequential array transducer. RESULTS Intraoperative vascular imaging was obtained on seven patients. Coronary ostia were normal in all except one. This patient had congenital stenosis of the left coronary ostium discovered during intraoperative imaging and confirmed by the surgeon. In another patient with Williams syndrome, the IMT was noted to be prominent. CONCLUSIONS It is feasible to perform intraoperative vascular imaging in less than 5 minutes of operator's time and provides superior visualization of the coronary ostia and IMT.

Abstract
OBJECTIVES We leveraged decomposition analysis, commonly used in labor economics, to understand determinants of cost differences related to location of admission in children undergoing neonatal congenital heart surgery. DESIGN A retrospective cohort study. SETTING Pediatric Health Information Systems database. PATIENTS Neonates (<30 d old) undergoing their index congenital heart surgery between 2004 and 2013. MEASUREMENTS AND MAIN RESULTS A decomposition analysis with bootstrapping determined characteristic (explainable by differing covariate levels) and structural effects (if covariates are held constant) related to cost differences. Covariates included center volume, age at admission, prematurity, sex, race, genetic or major noncardiac abnormality, Risk Adjustment for Congenital Heart Surgery-1 score, payor, admission year, cardiac arrest, infection, and delayed sternal closure.Of 19,984 infants included (10,491 [52%] to cardiac ICU/PICU and 9,493 [48%] to neonatal ICU), admission to the neonatal ICU had overall higher average costs ($24,959 ± $3,260; p < 0.001) versus cardiac ICU/PICU admission. Characteristic effects accounted for higher costs in the neonatal ICU ($28,958 ± $2,044; p < 0.001). Differing levels of prematurity, genetic syndromes, hospital volume, age at admission, and infection contributed to higher neonatal ICU costs, with infection rate providing the most significant contribution ($13,581; p < 0.001). Aggregate structural effects were not associated with cost differences for those admitted to the neonatal ICU versus cardiac ICU/PICU (p = 0.1). Individually, prematurity and age at admission were associated with higher costs due to structural effects for infants admitted to the neonatal ICU versus cardiac ICU/PICU. CONCLUSIONS The difference in cost between neonatal ICU and cardiac ICU/PICU admissions is largely driven by differing prevalence of risk factors between these units. Infection rate was a modifiable factor that accounted for the largest difference in costs between admitting units.

Abstract
INTRODUCTION Hospital readmission is an important driver of costs among patients with CHD. We assessed predictors of 30-day rehospitalisation following cardiac surgery in CHD patients across the lifespan. METHODS This was a retrospective analysis of 981 patients with CHD who had cardiac surgery between January 2011 and December 2012. A multivariate logistic regression model was used to identify demographic, clinical, and surgical predictors of 30-day readmission. Receiver operating curves derived from multivariate logistic modelling were utilised to discriminate between patients who were readmitted and not-readmitted at 30 days. Model goodness of fit was assessed using the Hosmer-Lemeshow test statistic. RESULTS Readmission in the 30 days following congenital heart surgery is common (14.0%). Among 981 patients risk factors associated with increased odds of 30-day readmission after congenital heart surgery through multivariate analysis included a history of previous cardiac surgery (p < 0.001), longer post-operative length of stay (p < 0.001), as well as nutritional (p < 0.001), haematologic (p < 0.02), and endocrine (p = 0.04) co-morbidities. Patients who underwent septal defect repair had reduced odds of readmission (p < 0.001), as did children (p = 0.04) and adult (p = 0.005) patients relative to neonates. CONCLUSION Risk factors for readmission include a history of cardiac surgery, longer length of stay, and co-morbid conditions. This information may serve to guide efforts to prevent readmission and inform resource allocation in the transition of care to the outpatient setting. This study also demonstrated the feasibility of linking a national subspecialty registry to a clinical and administrative data repository to follow longitudinal outcomes of interest.

Abstract
Previous reports have identified risk factors associated with development of post-Fontan protein-losing enteropathy. Less is known about the economic impact and resource utilisation required for post-Fontan protein-losing enteropathy in the current era. We conducted a single-centre retrospective study to assess the impact of post-Fontan protein-losing enteropathy on transplant-free survival. We also described resource utilisation and treatment variations among post-Fontan protein-losing enteropathy patients. Children who received care at our centre between 2009 and 2017 after the Fontan surgery were eligible. Initial admissions for the Fontan operative procedure were excluded. Demographics, hospital admissions, resource utilisation, medications and charges were reviewed. Patients were divided into two groups based on the presence of post-Fontan protein-losing enteropathy. Of the 343 patients screened, 147 met the eligibility criteria. Of these, 28 (19%) developed protein-losing enteropathy. After adjusting for follow-up duration, the protein-losing enteropathy group had higher number of encounters (2.15 ± 2.16 versus 1.47 ± 2.56, p 0.002), hospital length of stay (days) (25 ± 51.3 versus 11.4 ± 41.7, p < 0.0001) and total charges (2018US$) (388,489 ± 759,859 versus 202,725 ± 1,076,625, p < 0.0001). Encounters for patients with protein-losing enteropathy utilised more therapies. Among those with protein-losing enteropathy, use of digoxin was associated with slightly decreased odds for mortality and/or transplant (0.95, confidence interval 0.90-0.99, p 0.021). The 10-year transplant-free survival for patients with/without protein-losing enteropathy was 65.7/97.3% (p 0.002), respectively. Post-Fontan protein-losing enteropathy is associated with reduced 10-year transplant-free survival, higher resource utilisation, charges and medication use compared with the non-protein-losing enteropathy group. Practice variation among post-Fontan protein-losing-enteropathy patients is common. Further larger studies are needed to assess the impact of standardisation on the well-being of children with post-Fontan protein-losing enteropathy.

Abstract
Mycotic pseudoaneurysm of the aorta is a rare and lethal complication of pediatric congenital heart surgery. We report the lethal consequences of recurrent mycotic pseudoaneurysm in an 18-month-old baby, early after subaortic membrane resection. We managed to repair the pseudoaneurysm successfully by replacing the infected ascending aorta using bovine jugular vein graft, but unfortunately, the patient developed new pseudoaneurysm at the site of anastomosis which led to his death. Although prompt diagnosis and surgical management can save the patient life, uncontrolled infection can lead to the recurrence of the problem and lethal results.

Abstract
The coronavirus disease 2019 (COVID-19) pandemic currently gripping the globe is impacting the entire health care system with rapidly escalating morbidities and mortality. Although the infectious risk to the pediatric population appears low, the effects on children with congenital heart disease (CHD) remain poorly understood. The closure of congenital heart surgery programs worldwide to address the growing number of infected individuals could have an unintended impact on future health for COVID-19-negative patients with CHD. Pediatric and congenital heart surgeons, given their small numbers and close relationships, are uniquely positioned to collectively assess the impact of the pandemic on surgical practice and care of children with CHD. We present the results of an international survey sent to pediatric and congenital heart surgeons characterizing the early impact of COVID-19 on the care of patients with CHD.

Abstract
BACKGROUND Diaphragm paralysis (DP) complicates the postoperative course of neonates and infants undergoing cardiac surgery. Events causing DP remain poorly understood, and preventive strategies remain elusive. This retrospective cohort analysis aims to test the hypothesis that chest tubes in contact with the phrenic nerve in the pleural apex may cause pressure palsy. METHODS In late 2018, the chest tube positioning strategy was changed so as to avoid a putative "danger zone" configuration, defined as (1) the chest tube looping apicomedially at the level of the second right intercostal space, and (2) wedging of chest tube tip against pericardium. A preintervention and postintervention analysis of 531 patients from 2012 to 2019 was performed to evaluate any association of chest tube position or duration in place with DP. Univariable and multivariable analyses were carried out, with significance set a priori at P < .05. RESULTS The preintervention group comprised 488 patients, of whom 32 (6.6%) had RDP. The postintervention group comprised 43 patients, none of whom had DP. Multivariable analysis of the entire cohort revealed chest tube positioning in the danger zone as the only significant association with RDP (odds ratio, 4.22; 95% confidence interval, 1.57-11.33; P < .05). CONCLUSIONS Chest tubes that occupy the right superior pleural space are associated with increased risk of DP.

Abstract
Antibiotic prophylaxis following delayed sternal closure in pediatric cardiac surgery is not standardized. We systematically reviewed relevant literature published between 1990 and 2019 to aid future trial design. Patient characteristics, antimicrobial prophylaxis regimens, and postoperative incidence of infection were collected. Twenty-eight studies described 36 different regimens in over 3,000 patients. There were 11 single-drug regimens and 25 multidrug regimens. Cefazolin-only was the most common regimen (9/36, 25%). The overall incidence of surgical site infection was 7.5% (217/2,910 patients) and bloodstream infection was 7.4% (123/1,667 patients). In the 2010s, multidrug regimens were associated with a significantly lower incidence of both surgical site infections (4.6% vs. 20%, P < .001) and bloodstream infections (6.0% vs. 50%, P < .001) compared to single-drug regimens.

Abstract
BACKGROUND A Konno operation with a mechanical prosthesis may be applied in patients with complex left ventricular outflow tract obstruction to avoid further operations. We reviewed our 20-year experience with the Konno operation. METHODS All patients who underwent the Konno operation between 1996 and 2015 were evaluated. Study end points were survival and reoperations. RESULTS Twenty-one consecutive patients were included. The median age at operation was 12 years (5 months to 34 years). Twenty (95%) patients had prior interventions for left-sided heart lesions. Additional mitral valve disease was present in 17 (81%) patients. The preoperative mean pressure gradient over the left ventricular outflow tract was 50 ± 25 mm Hg. The median size of implanted valve prostheses was 21 mm (16-25 mm). Concomitant procedures for left-sided heart lesions were performed in six patients, including two mitral valve replacements. There were two hospital mortalities (9.5%) and four late mortalities (19%). Overall survival was 85% ± 7.8% and 72% ± 11% at 5 and 10 years, respectively. In two patients, mitral valve replacement was performed during the same hospital admission. During a mean follow-up time of 7.6 ± 4.8 years, two patients required late reoperations, one for mitral valve replacement and one for heart transplantation. Freedom from late reoperation at 10 years was 89% ± 7.4%. CONCLUSIONS The Konno operation can be considered as a definitive option with a low probability of reoperation on the left ventricular outflow tract in patients with complex left ventricular heart disease. Subsequent operations focus on the treatment of additional mitral valve disease, which remains the cause of mortality and morbidity.

Abstract
OBJECTIVE The objective of this study was to assess the effectiveness of transversus thoracic muscle plane block (TTPB) as a novel technique for postoperative analgesia in pediatric cardiac surgery. DESIGN A retrospective study. SETTING A tertiary care teaching hospital. PARTICIPANTS Children who underwent congenital heart surgery through median sternotomy between January 2018 and March 2019. INTERVENTIONS Bilateral ultrasound-guided TTPB was performed as a single-shot technique before the sternal incision. A total dose of bupivacaine 0.25% (0.5 ml/kg) was injected between the fourth and fifth ribs just lateral to the sternum. Patients who received TTPB were designated as the TTPB group, and the other group was named the non-TTPB group MEASUREMENTS AND MAIN RESULTS: Thirty-three patients underwent intraoperative bilateral TTPB before the sternal incision and 37 did not. The groups were comparable as for demographic and intraoperative clinical characteristics. Pain scores were significantly lower in the TTPB group compared with the non-TTPB group (p < 0.001). Intraoperatively, non-TTPB patients received significantly higher doses of fentanyl (p < 0.001). Moreover, the total fentanyl dose during a 24-hour period was also higher in the non-TTPB group (p < 0.001). The time to extubation was significantly lower in the TTPB group than in the non-TTPB group (p < 0.001). CONCLUSIONS TTPB appeared to be an effective technique for postoperative analgesia in pediatric patients undergoing cardiac surgery using a median sternotomy approach.

Abstract
OBJECTIVE Prior studies demonstrate an association between nonwhite race/ethnicity, insurance status, and mortality after pediatric congenital heart surgery. The influence of severity of illness on that association is unknown. We examined the relationship between race/ethnicity, severity of illness, and mortality in congenital cardiac surgery, and whether severity of illness is a mechanism by which nonwhite patients experience increased surgical mortality. METHODS We performed a retrospective cohort study of children younger than age 18 years old undergoing cardiac surgery admitted to the intensive care unit (n = 40,545) between 2009 and 2016 from the Virtual Pediatric Systems (VPS, LLC, Los Angeles, Calif) database. Multivariate regression models were constructed to examine the role of severity of illness as a mediator between race/ethnicity and mortality in children undergoing cardiac surgery. RESULTS In multivariate models examining severity of illness scores, African-American patients had statistically significant higher severity of illness scores when compared with their white counterparts. In multivariate models of intensive care unit mortality after adjustment for covariates, African-American patients had a higher odds of postoperative mortality (odds ratio, 1.40, 95% confidence interval, 1.04-1.89) when compared with white children. This increased odds of mortality was mediated through higher severity of illness, because adjustment for severity of illness removed this survival disadvantage for black patients. CONCLUSIONS Although African-American children undergoing cardiac surgery had higher postoperative mortality, this survival difference appears to be mediated via severity of illness. Preoperative and intraoperative factors may be drivers for this survival disparity.

Abstract
We propose several considerations for implementation of critical congenital heart disease (CCHD) screening for low- and middle-income countries to assess health system readiness for countries that may not have all the downstream capacity needed for treatment of CCHD. The recommendations include: (1) assessment of secondary and tertiary level CHD health services, (2) assessment of birth delivery center processes and staff training needs, (3) data collection on implementation and quality surgical outcomes, (4) budgetary consideration, and (5) consideration of the CCHD screening service as part of the overall patient care continuum.

Anesthesia for bilateral pulmonary banding as part of hybrid stage I approach palliating neonates with hypoplastic left heart syndrome. Paediatr Anaesth 2020; 30:691-697. [PMID: 32291873 DOI: 10.1111/pan.13876] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/22/2019] [Revised: 03/11/2020] [Accepted: 04/05/2020] [Indexed: 11/29/2022]
Abstract
BACKGROUND Neonatal management of patients with hypoplastic left heart syndrome and complex remains a challenging task, whereby the "hybrid" palliation is often reserved for high-risk patients as a "rescue" procedure. AIM This study documents the anesthetic challenges and potential complications associated with the Giessen hybrid stage I approach. METHODS The Giessen hybrid stage I approach is focused on surgical bilateral pulmonary artery banding. Retrospective perioperative data were analyzed. Contrary to a stable group A, inotropic treatment before surgery for treatment of postnatal shock classified patients as unstable (Group B). Clinical outcomes considered were inhospital mortality, duration of postoperative mechanical ventilation, postoperative time at the intensive care unit, perioperative vasoactive medication requirements, and red blood cell transfusion. RESULTS From June 1998 to December 2015, 185 patients were allocated to Group A (n = 165) and Group B (n = 20). The inhospital mortality was 2.2% with no difference between the groups. There was also no difference in the postoperative time on mechanical ventilation and the time in the intensive care unit. Vasoactive medication was more often required in Group B (100%) compared to Group A (19%). In Group B, more red blood cells were transfused 6.0 ± 8.3 vs 2.0 ± 5.8 mL/kg in Group A (P < .05, 95% CI 0.0 - 2.6). CONCLUSION Considering a learning curve, anesthesia for surgical bilateral pulmonary artery banding palliating patients with hypoplastic left heart syndrome and complex can safely be performed, independent from the preoperative clinical status.

Abstract
OBJECTIVE To determine risk factors for re-replacement and death or transplant following mitral valve replacement (MVR) in children METHODS: This is a retrospective 26-year review of patients younger than 20 years of age undergoing MVR between 1992 and 2018 at single institution. Outcomes included freedom from re-MVR and transplant-free survival. Cox proportional hazards regression models assessed association between outcomes and potential risk factors. RESULTS At median age 4.2 years, 190 children underwent 290 MVR: 180 mechanical, 63 porcine, 13 pericardial, and 34 stented bovine jugular vein valves. Re-MVR occurred in 100 valves. Freedom from re-MVR at 5 and 10 years was 76% and 44%. Times to re-MVR were associated with prosthesis type (P < .001), with porcine and pericardial valves at greatest risk. Other risk factors for prosthetic failure included smaller prosthesis size and left ventricular hypoplasia. There were 9 transplants and 44 deaths. Transplant-free survival at 5 and 10 years was 81% and 76%. Prosthesis type was significantly associated with time to death/transplant in univariate analysis only (P = .021), with porcine at greater risk than mechanical. Independent risk factors for death/transplant included larger indexed geometric orifice area and longer bypass time. CONCLUSIONS In pediatric patients undergoing MVR, mechanical and stented bovine jugular vein valves were associated with increased durability compared with fixed-diameter bioprosthetic alternatives.

Abstract
We conducted a candidate gene association study to test the hypothesis that different gene polymorphisms will be associated with corticosteroid responsiveness and study outcomes among children undergoing congenital heart surgery. This is a prospective observational cohort study at a large, tertiary pediatric cardiac center on children undergoing corrective or palliative congenital heart surgery. A total of 83 children were enrolled. DNA was isolated for three polymorphisms of interest namely N363 (rs56149945) and 9β (rs6198) associated with increased sensitivity to corticosteroids and Bcl I (rs41423247) associated with decreased sensitivity to corticosteroids. Duration of inotropic use, low cardiac output scores (LCOS), and vasoactive inotrope scores were examined in relation to these three polymorphisms. Using Kaplan-Meier analysis, heterozygous individuals showed longer transcriptional intermediary factor (TIF) compared with wild type for N363 polymorphism ( p = 0.05). In multivariable Cox regression, heterozygous alleles for 9β polymorphism showed significantly shorter TIF compared with wild type (hazard ratio = 2.04 [1.08-3.87], p = 0.03). The relationship between lower LCOS scores and alleles groups was significant for 9β heterozygous polymorphism only (1.5 [1-2.2], p = 0.01) in comparison to wild type and homozygous. The presence of heterozygote alleles for the increased corticosteroid sensitivity is associated with longer TIF compared with wild type. Conversely, the presence of heterozygous alleles for the decreased sensitivity to corticosteroids is associated with shorter TIF compared with wild type.

Abstract
Background Acute kidney injury (AKI) is a commonly recognized clinical problem after congenital heart disease (CHD) surgery. Increased perioperative morbidity, development of chronic kidney disease, and increased mortality are the major concerns. We investigated frequency, risk factors, and outcomes of AKI after CHD surgery at our hospital. Methods This study was a retrospective analytic review conducted from January 2013 to October 2016 on patients aged between 1 month and 45 years who underwent cardiopulmonary bypass (CPB) for CHD surgery. The modified Kidney Disease Improving Global Outcomes criteria based on serum creatinine value was adopted to diagnose AKI. We assessed AKI frequency and its staging, and outcomes as AKI resolution, length of stay, and mortality. Stages II and III (plasma creatinine level two or more times the baseline) were labeled as severe AKI. Univariate and multivariate logistic regression analyses were conducted, and results were reported as mean with standard deviation and as frequencies with percentage. Odds ratios (ORs) with 95% confidence intervals (CIs) were reported for factors associated with the development of AKI. Results Of the 840 patients who underwent CHD surgery, 237 (28%) developed AKI. AKI stages II1 and III were seen in 101 (42%) and 103 (43%) patients, respectively. Prolonged CPB time > 120 minutes (adjusted OR [AOR]: 1.87; 95% CI: 1.22-2.88; p = 0.004) and hemoglobin > 16 gm/dL (AOR: 1.80; 95% CI: 1.16-2.78; p = 0.008) were associated with the development of AKI on multivariate analysis. AKI resolved spontaneously in 222 (94%) patients, and 10 (4%) patients who developed AKI died. Conclusions Most patients with AKI showed spontaneous resolution. Prolonged CPB time and increased hemoglobin were found to be significant risk factors. Our study found spontaneous resolution of AKI in most cases. However, preplanning and careful monitoring in patients with expected prolonged CPB time and increased baseline hemoglobin can prevent and identify AKI at an early stage.

Abstract
BACKGROUND Vasoactive medications are commonly administered for afterload reduction and arterial hypertension treatment in patients after cardiac surgery. A systematic review and meta-analysis were conducted to determine the effects of sodium nitroprusside and nicardipine on hemodynamics and cardiac performance in this population. METHODS A systematic review of published manuscripts was performed to identify studies of patients who received sodium nitroprusside and nicardipine as part of the treatment for arterial hypertension or afterload reduction after cardiac surgery. A meta-analysis was then conducted to determine the effects of sodium nitroprusside and nicardipine on hemodynamics and cardiac performance. The following parameters were captured: blood pressure, heart rate, right atrial pressure, systemic vascular resistance, and stroke volume. RESULTS In total, five studies with 571 patients were pooled for these analyses. Systolic blood pressure, diastolic blood pressure, and mean arterial blood pressure were similar in both groups. The cardiac index was greater with nicardipine while mean pulmonary artery pressure was lower with sodium nitroprusside. CONCLUSION Nicardipine and sodium nitroprusside have similar abilities in reducing afterload in the postoperative cardiac population. Statistically significant differences were found in pulmonary artery pressure and cardiac index. It may be beneficial to consider nicardipine for afterload reduction in patients with a low cardiac index.

Post-Cardiotomy Parasternal Nerve Block with Bupivacaine may be Associated with Reduced Post-Operative Opioid Use in Children: A Retrospective Cohort Study. CHILDREN-BASEL 2020; 7:children7030020.

Abstract
Postoperative pain treatment affects immediate and long-term outcomes in children undergoing cardiac surgery. Opioids, as part of multimodal analgesia, are effective in treating pain, however, they can be disadvantageous due to adverse side effects. Therefore, we assessed whether the local anesthetic bupivacaine as a parasternal nerve block in children post-cardiac surgery is an effective adjunct to pain management. This was a retrospective cohort study of all patients who underwent cardiothoracic surgery via median sternotomy at a large children’s hospital between November 2011 and February 2014 with and without bupivacaine following the introduction of perioperative bupivacaine in late 2012 on a single unit. 62 out of 148 patients (age 3–17 years) who received bupivacaine demonstrated decreased postoperative opioid use. Within one day of surgery, patients who received bupivacaine required, on average, 0.57 mg/kg (95% CI, 0.46 to 0.68) of total morphine equivalent compared to 0.93 mg/kg (95% CI, 0.80 to 1.06) for patients who did not receive bupivacaine. This difference was statistically significant after adjusting for potential confounders (p-value = 0.002). Length of stay and intubation were shorter on average among patients who received bupivacaine, but these differences were not statistically significant after adjusting for potential confounders. The study results seem to suggest that the perioperative administration of bupivacaine may reduce opioid usage among children post-cardiotomy.

Abstract
Cavopulmonary anastomosis was first described by Carlon, Mondini, De Marchi in a canine model in 1951 and later, in the clinical practice, by Glenn in 1958. Total right heart bypass was first introduced by Fontan and Kreutzer in 1971, in each instance as treatment for tricuspid atresia. Several modifications of such a procedure followed the initial concept of the right atrium as a pumping chamber, including modifications aimed to minimize energy loss at the anastomotic level and arrhythmias. Tribute is given to our pioneers who developed such an operation aimed to treat any child with functionally univentricular hearts.
