Abstract
Introduction Diffuse alveolar hemorrhage (DAH) is a devastating disease process with 50-100% mortality in oncology and hematopoietic cell transplant (HCT) recipients. High concentrations of tissue factors have been demonstrated in the alveolar wall in acute respiratory distress syndrome and DAH, along with elevated levels of tissue factor pathway inhibitors. Activated recombinant factor VII (rFVIIa) activates the tissue factor pathway, successfully overcoming the tissue factor pathway inhibitor (TFPI) inhibition of activation of Factor X. Intrapulmonary administration (IP) of rFVIIa in DAH is described in small case series with successful hemostasis and minimal complications. Methods We completed a single center retrospective descriptive study of treatment with rFVIIa and outcomes in pediatric oncology and HCT patients with pulmonary hemorrhage at a quaternary hematology/oncology hospital between 2011 and 2019. We aimed to assess the safety and survival of patients with pulmonary hemorrhage who received of IP rFVIIa. Results We identified 31 patients with pulmonary hemorrhage requiring ICU care. Thirteen patients received intrapulmonary rFVIIa, while eighteen patients did not. Overall, 13 of 31 patients (41.9%) survived ICU discharge. ICU survival (n=6) amongst those in the IP rFVIIa group was 46.2% compared to 38.9% (n=7) in those who did not receive IP therapy (p=0.69). Hospital survival was 46.2% in the IP group and 27.8% in the non-IP group (p=0.45). There were no adverse events noted from use of IP FVIIa. Conclusions Intrapulmonary rFVIIa can be safely administered in pediatric oncology patients with pulmonary hemorrhage and should be considered a viable treatment option for these patients.

Abstract
We examined risk factors for red blood cell (RBC) alloimmunization in pediatric patients with sickle cell disease, focusing on the recipients' inflammatory state at the time of transfusion and anti-inflammatory role of hydroxyurea (HU). Among 471 participants, 55 (11.70%) participants were alloimmunized and formed 59 alloantibodies and 17 autoantibodies with an alloimmunization rate of 0.36 alloantibodies per 100 units. Analysis of 27 participants in whom alloantibodies were formed with specificities showed 23.8% (30/126) of units transfused during a proinflammatory event resulting in alloantibody formation compared with 2.8% (27/952) of units transfused at steady state. Therefore, transfusion during proinflammatory events increased the risk for alloimmunization (odds ratio [OR], 4.22; 95% confidence interval [CI], 1.64-10.85; P = .003). Further analysis of all the 471 participants showed that alloimmunization of patients who received episodic transfusion, mostly during proinflammatory events, was not reduced with HU therapy (OR, 6.52; 95% CI, 0.85-49.77; P = .071), HU therapy duration (OR, 1.13; 95% CI, 0.997-1.28; P = .056), or HU dose (OR, 1.06; 95% CI, 0.96-1.16; P = .242). The analysis also identified high transfusion burden (OR, 1.02; 95% CI, 1.003-1.04; P = .020) and hemoglobin S (HbSS) and HbSβ0-thalassemia genotypes (OR, 11.22, 95% CI, 1.51-83.38; P = .018) as additional risk factors for alloimmunization. In conclusion, the inflammatory state of transfusion recipients affects the risk of RBC alloimmunization, which is not modified by HU therapy. Judicious use of transfusion during proinflammatory events is critical for preventing alloimmunization.

Abstract
We adjusted haematopoietic stem and progenitor cell (HSPC) apheresis collection from patients with sickle cell disease (SCD) by targeting deep buffy coat collection using medium or low collection preference (CP), and by increasing anticoagulant-citrate-dextrose-solution A dosage. In 43 HSPC collections from plerixafor-mobilized adult patients with SCD, we increased the collection efficiency to 35.79% using medium CP and 82.23% using low CP. Deep buffy coat collection increased red blood cell contamination of the HSPC product, the product haematocrit was 4.7% with medium CP and 6.4% with low CP. These adjustments were well-tolerated and allowed efficient HSPC collection from SCD patients.

Abstract
Pain in sickle cell disease (SCD) can have a neuropathic component. This randomized phase II double-blinded placebo-controlled study evaluated the efficacy of gabapentin in reducing pain and opioid consumption (morphine-equivalent dose [MED]) during acute vaso-occlusive crisis (VOC). Of 90 patients aged 1-18 years with VOC pain, 45 were randomized to a single gabapentin dose (15 mg/kg) and 45 to placebo, in addition to standard treatment; 42 and 44 patients were evaluable in the gabapentin and placebo arms, respectively. A decrease in pain of ≥33% was reported in 68% of patients in the gabapentin arm and 60% of those in the placebo arm (one-sided p = 0.23). The median MED (mg/kg) in the gabapentin (0.12) and placebo arms (0.13) was similar (p = 0.9). However, in the subset of patients with the HbSS genotype (n = 45), the mean (SD) absolute pain score decrease by the time of discharge was significantly greater in the gabapentin arm (5.9 [3.5]) than in the placebo arm (3.6 [3.3]) (p = 0.032). Pain scores in the overall study population were not significantly reduced when gabapentin was added to standard treatment; however, gabapentin benefited individuals with the more severe genotype, HbSS, during acute VOC. Larger, prospective studies are needed to confirm these findings.

Abstract
OBJECTIVES To evaluate the impact of regional cerebral perfusion (RCP) during heart operation on outcomes in neonates undergoing Norwood operation. METHODS We performed a retrospective cohort study using data from the Single Ventricle Reconstruction trial data set. The adjusted effect of RCP use on each outcome was studied using a penalized logistic regression model with bootstrap validation. RESULTS Of 549 patients included in the study, 252 patients (45.9%) received RCP during their heart operation. In univariate comparisons, the majority of the baseline characteristics and preoperative risk factors were similar in the RCP and No RCP group. The total cardiopulmonary bypass (CPB) time and the total cross-clamp (CC) time were longer in the RCP group (RCP vs No RCP, median CPB time: 161 minutes vs 109 minutes; median CC time: 63 minutes vs 43 minutes). In adjusted models, the use of RCP was not associated with decreased mortality and/or need for heart transplant at hospital discharge (odds ratio [OR]: 0.73; 95% confidence interval [CI]: 0.43-1.25) or prolonged mechanical ventilation (OR: 1.20, 95% CI: 0.62-2.28) or prolonged hospital length of stay (OR: 1.30, 95% CI: 0.73-2.30). We demonstrated that use of RCP was associated with longer CPB times, increased use of ultrafiltration, and higher probability of open chest after Norwood operation. CONCLUSIONS This study did not demonstrate any impact of RCP on in-hospital mortality and/or heart transplantation, prolonged mechanical ventilation, and prolonged hospital length of stay among neonates undergoing Norwood operation.

Abstract
Data investigating the impact of household income and other factors on SV patient status-post-Fontan palliation after heart transplantation are lacking. We aim to evaluate factors affecting outcomes after OHT in this population. The PHIS database was interrogated for either SV or myocarditis/primary CM who were 4 years or older who underwent a single OHT. There were 1599 patients with a median age of 13.2 years (IQR: 9.3-16.1). Total hospital costs were significantly higher in the SV group ($408 000 vs $294 000, P < 0.0001), but as median household income increased, the risk of inhospital mortality, post-transplant LOS, and LOS-adjusted total hospital costs all decreased. The risk of inhospital mortality increased 6.5% per 1 year of age increase at the time of transplant. Patients in the SV group had significantly more diagnoses than those in the CM group (21 vs 15, P < 0.0001) and had longer total hospital LOSs as a result of longer post-transplant courses (25 days vs 15, P < 0.0001). Increased median household income and younger age are associated with decreased resource utilization and improved inhospital mortality in SV CHD patients who undergo OHT. In conclusion, earlier consideration of OHT in this population, coupled with improved selection criteria, may increase survival in this population.

Abstract
The arterial switch operation (ASO) in complete transposition of the great arteries (TGA) has increased long-term survival. Annual follow-up echocardiograms are recommended, but evidence-based guidelines do not exist. We sought to assess how often a patient with TGA after ASO who had no symptoms or change in physical exam underwent an intervention based solely on echocardiographic changes. We retrospectively reviewed all records from patients with TGA and a history of ASO followed at our institution between November 1983 and January 2015. Changes in echocardiograms resulting in hospital admission, significant medication change, interventional catheterization, or surgical procedure were identified through the surgical and cardiac catheterization laboratory databases and patient charts. These changes were referred to as an actionable change (AC). Interventions were defined as being driven by either clinical (change in physical exam, patient and/or parental concerns) or echocardiographic findings. A total of 1,792 echocardiograms from 149 patients were reviewed. Median number of echocardiograms per patient was 12 (1 to 34). Of the 1,792 echocardiograms, 20 (1.12%) were associated with AC. The most common intervention for an AC was cardiac catheterization (13 of 20, 65%). Most AC (15 of 20, 75%) occurred in the first decade after ASO. AC occurred in 83% (5 of 6) of those with a history of both ASO and arch repair. Annual echocardiograms in patients with TGA after ASO are rarely useful and are unnecessary. In conclusion, decreasing surveillance of asymptomatic patients to biennial follow-up echocardiograms in asymptomatic patients without physical examination changes is safe and would decrease medical expenses.

Abstract
PURPOSE To create a real-time prediction tool to predict probability of ECMO deployment in children with cardiac or pulmonary failure. MATERIALS AND METHODS Patients ≤18 years old admitted to an ICU that participated in the Virtual Pediatric Systems database (2009-2015) were included. Logistic regression models using adaptive lasso methodology were used to identify independent factors associated with ECMO use. RESULTS A total of 538,202 ICU patients from 140 ICUs qualified for inclusion. ECMO was deployed in 3484 patients (0.6%) with a mortality of 1450 patients (41.6%). The factors associated with increased probability of ECMO use included: younger age, pulmonary hypertension, congenital heart disease, high-complexity cardiac surgery, cardiomyopathy, acute lung injury, shock, renal failure, cardiac arrest, use of nitric oxide, use of either conventional mechanical ventilation or high frequency oscillatory ventilation, and higher annual ECMO center volume. The area under the receiver operating curve for this model was 0.90 (95% CI: 0.85-0.93). This tool can be accessed at https://soipredictiontool.shinyapps.io/ECMORisk/. CONCLUSIONS Here, we present a tool to predict ECMO deployment among critically ill children; this tool will help create real-time risk stratification among critically ill children, and it will help with benchmarking, family counseling, and research.

Abstract
Right ventricular (RV) end-diastolic volume measured by cardiovascular magnetic resonance imaging (CMR) is a criterion for pulmonary valve replacement in patients with tetralogy of Fallot (TOF). We sought to determine if the ratio of echocardiographic, short-axis RV-to-left ventricular (LV) end-diastolic areas (EDA) could be used to predict RV volume on CMR. We retrospectively reviewed the echocardiograms of all patients with repaired TOF who underwent CMR at our institution from 2011 to 2015 and also had an echocardiogram within 6 months of the CMR. The short-axis RV and LV EDAs were measured and the ratio of the two was calculated. Results were compared with CMR RV end-diastolic volume index (RVEDVi) and RV:LV end-diastolic volume ratio. The sensitivity and specificity values predicting RV volumes > 150 ml/m2 were calculated. Fifty-eight studies met inclusion criteria. There were 47 studies with RVEDVi < 150 ml/m2 and 11 with RVEDVi > 150 ml/m2. RV:LV EDA and CMR RV:LV end-diastolic volume ratio correlated strongly (r = 0.76, p < 0.0001). An RV:LV EDA ≥ 1.57 had a 90% sensitivity to predict RVEDVi > 150 ml/m2 (area under the curve = 0.74, 95% CI 1.5-27.9; p = 0.012). An RV:LV EDA ≥ 1.88 had an 81% specificity to detect RV volume index > 150 ml/m2. Short-axis RV:LV EDA correlates well with an increased RVEDVi as measured by CMR. This new and simple measure can be used to predict optimal timing for CMR in anticipation of pulmonary valve replacement in repaired TOF.

Abstract
PURPOSE To study the effect of cycloplegia on astigmatism measurements in pediatric patients with amblyopia. METHODS This was a prospective comparative clinical study. Participants 4 to 17 years old were recruited from the patient population at the Arkansas Children's Hospital eye clinic after informed consent was obtained. Autorefractor measurements were used to obtain values of refractive error in amblyopic and non-amblyopic patients before and after cycloplegia. The groups were subdivided into myopia and hyperopia and with and without underlying amblyopia. The refractive error was expressed as sphere, cylinder, axis of astigmatism, and spherical equivalent. The treatment effect was summarized as the mean difference (95% confidence interval) for each outcome. RESULTS No statistically significant difference was found on the axis and power of astigmatism before and after cycloplegia in the patients with amblyopia (P = .28 and .99, respectively). CONCLUSIONS Non-cycloplegic autorefraction measurements may be considered safe for refining astigmatism power and axis in pediatric patients with amblyopia.

Abstract
Objectives: The objectives were to assess the incidence of immediate tracheal extubation in the operating room after pediatric cardiac surgery and to investigate predictors for subsequent reintubation. Methods: This is a single institutional retrospective study including all patients who had a cardiac operation with cardiopulmonary bypass from 2011 to 2016. Patients who required preoperative ventilator support, postoperative open chest, or mechanical support were excluded. Predictors for reintubation after immediate extubation were analyzed only for patients with stage II palliation for single ventricle physiology. Results: Nine hundred nine qualifying operations were identified. Immediate extubation was performed in 590 (64.9%) operations. A multivariable logistic regression model showed that the identities of anesthesiologist ( P = .0003), year of the operation performed ( P < .001), cardiopulmonary bypass time ( P < .001), and type of operations ( P < .001) were significantly associated with immediate extubation. Reintubation was significantly less frequent in patients with immediate extubation compared to those without (6.1% vs 15.0%; P < .001). A subgroup analysis for stage II palliation showed that reintubation after immediate extubation was significant for younger age (0.42 vs 0.54 years, P = .044), lower Po2/Fio2 and Po2 at the last blood gas analysis (66 vs 98 mm Hg, P = .032 and 39 vs 47 mm Hg, P = .008), and higher inotropic score (2 vs 0, P = .034). A multivariable logistic regression model showed that only inotropic score was significantly associated with reintubation ( P = .018). Conclusions: Immediate extubation in the operating room after pediatric cardiac surgery can be performed in most patients. Inotropic score is a predictor for reintubation in stage II palliation.

Abstract
OBJECTIVE To evaluate the effect on mortality of reclassifying patients undergoing pediatric heart reoperations of varying complexity by operation of highest complexity instead of by first operation. METHODS Data from the Virtual Pediatric Systems Database on children aged < 18 years who underwent heart surgery (with or without cardiopulmonary bypass) were included (2009-2015). Only patients who underwent reoperations during the same hospitalization were included. Patients were classified based on the first cardiovascular operation (the index operation), and on the complexity of the operation (the operation with the highest Society of Thoracic Surgeons-European Association for Cardio-Thoracic Surgery [STAT] mortality category of each hospital admission) performed. RESULTS Of 51,047 patients (73 centers), 22,393 met inclusion criteria. Using index operation as the classifying operation, the number of patients classified in the STAT 1 category increased by approximately 2.5 times compared with the highest-complexity operation (index, 7,077 and highest complexity, 2,654). In contrast, when the highest-complexity classification was used, we noted an increase in the number of patients in other STAT categories. We also noted higher mortality in all STAT categories when patients were classified by index operation instead of by highest complexity (index vs highest STAT category 1, 0.6% vs 0.2%; category 2, 2.4% vs 0.8%; category 3, 3.1% vs 2.1%; category 4, 5.8% vs 5.6%; and category 5, 16.7% vs 16.5%). CONCLUSIONS This study demonstrates differences in the reported number of patients and reported mortality in each STAT category among children undergoing various heart reoperations during the same hospitalization by classifying patients based on index operation compared with the operation of highest complexity.

Abstract
Bicuspid aortic valve (BAV) is the most common congenital heart defect. BAV is associated with aortic stenosis and insufficiency, and aortic dilation in adult groups, but data in pediatric groups are limited. We sought to assess the impact of BAV morphology on aortic valve disease and aortic dilation in pediatric patients. We performed a retrospective review of all echocardiograms in patients with isolated BAV who were followed at our institution from July 2002 to July 2012. BAV morphology, aortic valve stenosis and/or insufficiency, and aortic dimensions were measured manually. Comparisons were made between right-left cusp fusion (RL) and right-noncoronary cusp fusion (RN) BAV morphologies. Generalized least square models were fit to analyze the impact of specific variables on aortic dilation. There were 1075 echocardiograms in 366 patients (72% male) with isolated BAV. Aortic valve insufficiency and stenosis were more common in RN (p < 0.001 for both). The median aortic sinus Z score was higher in the RL (0.47; IQR - 0.31 to 1.44) than in the RN group (0.02; - 0.83 to 0.82) (p < 0.001). There was no difference in median ascending aorta Z score between groups. Patients with the highest weights had larger aortas (p < 0.001), but the absolute difference between the highest and lowest weight groups was small (1.5 mm). The impact of BAV morphology on aortic valve disease and aortic dilation in pediatric patients presages that seen in adults. Patient body weight does not make significant clinical impacts on aortic diameters, suggesting that Z scores for aortic diameters should be based on ideal body weights.

Abstract
We aimed to empirically derive an inotrope score to predict real-time outcomes using the doses of inotropes after pediatric cardiac surgery. The outcomes evaluated included in-hospital mortality, prolonged hospital length of stay, and composite poor outcome (mortality or prolonged hospital length of stay). The study population included patients <18 years of age undergoing heart operations (with or without cardiopulmonary bypass) of varying complexity. To create this novel pediatric cardiac inotrope score (PCIS), we collected the data on the highest doses of 4 commonly used inotropes (epinephrine, norepinephrine, dopamine, and milrinone) in the first 24 hours after heart operation. We employed a hierarchical framework by representing discrete probability models with continuous latent variables that depended on the dosage of drugs for a particular patient. We used Bayesian conditional probit regression to model the effects of the inotropes on the mean of the latent variables. We then used Markov chain Monte Carlo simulations for simulating posterior samples to create a score function for each of the study outcomes. The training dataset utilized 1030 patients to make the scientific model. An online calculator for the tool can be accessed at https://soipredictiontool.shinyapps.io/InotropeScoreApp. The newly proposed empiric PCIS demonstrated a high degree of discrimination for predicting study outcomes in children undergoing heart operations. The newly proposed empiric PCIS provides a novel measure to predict real-time outcomes using the doses of inotropes among children undergoing heart operations of varying complexity.

Abstract
Background: The existing training pathways to become a pediatric cardiac intensivist are very variable with physicians coming from varied training backgrounds of pediatric critical care, pediatric cardiology, neonatology, or pediatric anesthesia. Aim: To evaluate the impact of cardiac Intensive Care Unit (ICU) attending physician training background on outcomes in children undergoing heart operations. Setting and Design: Patients in the age group from 1 day to 18 years undergoing heart operation at a Pediatric Health Information System database participating hospital were included (2010–2015). Patients and Methods: Based on the training background of majority of attending physicians in an ICU, the participating ICUs were divided into three groups: critical care medicine (CCM), cardiology, and indeterminate. Statistical Analysis: Multivariable logistic regression models were fitted to evaluate the association of ICU physician training background with study outcomes. Results: A total of 54,935 patients from 42 ICUs were included. Of these, 31,815 patients (58%) were treated in the CCM group (26 ICUs), 19,340 patients (35%) were treated in the cardiology group (12 ICUs), and 3780 patients (7%) were treated in the indeterminate group (4 ICUs). In adjusted models, no specific group based on ICU attending physician training background was associated with lower mortality (CCM vs. cardiology, odds ratio: 0.75, 95% confidence interval: 0.48–1.18), or lower incidence of cardiac arrest, or prolonged hospital length of stay, or prolonged mechanical ventilation. Conclusions: This large observational study did not demonstrate any impact of ICU attending training background on outcomes in children undergoing heart operations.

Abstract
BACKGROUND AND OBJECTIVES Congenital heart disease (CHD) is common in trisomy 13 (T13) and trisomy 18 (T18), but surgical repair has not been offered in most centers. Data on outcomes of congenital heart surgery (CHS) for T13 and T18 are lacking. We sought to determine the impact of CHS on in-hospital mortality in T13 and T18. METHODS Data from the 2004 to 2015 Pediatric Health Information System database were used to identify inpatients with T13 or T18 and CHD. Data were restricted to newborns with T13 or T18 admitted at ≤14 days of age. Hospital readmissions were examined to analyze longer-term in-hospital mortality. In-hospital mortality and length of stay were compared between infants with and without CHD and with and without CHS. RESULTS The study cohort included 1020 infants with T18 and 648 infants with T13. CHD was present in 91% of infants with T18 and 86% of infants with T13. CHS was performed in 7% of each group. In-hospital mortality was decreased in those who underwent CHS (64% lower in T18 [P <.001]; 45% lower in T13 [P = .003]) and remained decreased throughout the 24 months of follow-up. In-hospital mortality was decreased in infants with higher weight, female sex, and older age at admission. CONCLUSIONS CHS is associated with decreased in-hospital mortality in T18 and T13. These results suggest CHS may be beneficial in select cases.

Abstract
PURPOSE With increasing emphasis on high-quality care, we designed this study to evaluate the relationship between Magnet® recognition and patient outcomes in pediatric critical care. MATERIALS AND METHODS Post hoc analysis of data from an existing administrative national database. We used inverse probability of treatment weighting and multivariate models to compare outcomes between two study groups after adjusting for confounding variables. RESULTS A total of 823,634 pediatric patients from 41 centers were included. Of these, 454,616 patients (55.2%) were treated in 23 Magnet hospitals. The majority of baseline characteristics did not vary significantly among the two study groups. In adjusted models, there was no difference in mortality between the two groups (Magnet vs. non-Magnet; odds ratio: 0.92, 95% confidence interval: 0.77-1.11). When stratified by various subgroups, such as cardiac, non-cardiac, ECMO, cardiac arrest, respiratory failure, use of nitric oxide, genetic abnormality etc., Magnet status of the hospital did not confer a survival advantage. In a sensitivity analysis on patients from crossover hospitals only, attainment of magnet status was associated with increased hospital charges. CONCLUSIONS This large observational study calls into question the utility of the Magnet Recognition Program among children with critical illness, at least among the freestanding children's hospitals.

Abstract
PURPOSE A kaolin-impregnated hemostatic sponge (QuikClot) is reported to reduce intraoperative blood loss in trauma and noncardiac surgery. The purpose of this study was to assess if this sponge was effective for hemostasis during Norwood operation. DESCRIPTION We conducted a retrospective review of patients undergoing Norwood operation in infancy between 2011 and 2016 at our institution. EVALUATION Of 31 identified Norwood operations, a kaolin-impregnated sponge was used intraoperatively in 15 (48%) patients. The preoperative profiles and cardiopulmonary bypass status were similar between the operations with or without kaolin-impregnated sponge. The comparison on each operative outcome between operations with or without kaolin-impregnated sponge showed that the intraoperative platelets, cryoprecipitate, and factor VII dosage were significantly less in the operations with kaolin-impregnated sponge (55 mL, 10 mL, 0 µg/kg vs 72 mL, 15 mL, 45 µg/kg; P = .03, .021, .019), as well as the incidence of perioperative bleeding complications (second cardiopulmonary bypass for hemostasis or postoperative mediastinal exploration, 0% vs 31%, P = .043). A logistic regression model showed that the nonuse of kaolin-impregnated sponge and longer aortic cross clamp time were associated with perioperative bleeding complication in univariable model ( P = .02 and .005). CONCLUSIONS Use of kaolin-impregnated hemostatic sponge was associated with reduced blood product use and perioperative bleeding complications in Norwood operation at a single institution.

Abstract
A ferromagnetic surgical system (FMwand®) is a new type of dissection device expected to reduce the risk of adjacent tissue damage. We reviewed 426 congenital cardiac operations with cardiopulmonary bypass through redo sternotomy to assess if this device prevented phrenic nerve injury. The ferromagnetic surgical system was used in 203 operations (47.7%) with regular electrocautery and scissors. The preoperative and operative details were similar between the operations with or without the ferromagnetic surgical system. The incidence of phrenic nerve injury was significantly lower with the ferromagnetic surgical system (0% vs 2.7%, P = 0.031). A logistic regression model showed that the use of the ferromagnetic surgical system was significantly associated with reduced odds of phrenic nerve injury (P < 0.001).

Abstract
OBJECTIVES To characterize cardiac arrest in children undergoing cardiac surgery using single-center data from the Society of Thoracic Surgeons and Pediatric Advanced Life Support Utstein-Style Guidelines. METHODS Patients aged 18 years or less having a cardiac arrest for 1 minute or more during the same hospital stay as heart operation qualified for inclusion (2002-2014). Patients having a cardiac arrest both before or after heart operation were included. Heart operations were classified on the basis of the first cardiovascular operation of each hospital admission (the index operation). The primary outcome was survival to hospital discharge. RESULTS A total of 3437 children undergoing at least 1 heart operation were included. Overall rate of cardiac arrest among these patients was 4.5% (n = 154) with survival to hospital discharge of 84 patients (66.6%). Presurgery cardiac arrest was noted among 28 patients, with survival of 21 patients (75%). Among the 126 patients with postsurgery cardiac arrest, survival was noted among 84 patients (66.6%). Regardless of surgical case complexity, the median days between heart operation and cardiac arrest, duration of cardiac arrest, and survival after cardiac arrest were similar. The independent risk factors associated with improved chances of survival included shorter duration of cardiac arrest (odds ratio, 1.12; 95% confidence interval, 1.05-1.20; P = .01) and use of defibrillator (odds ratio, 4.51; 95% confidence interval, 1.08-18.87; P = .03). CONCLUSIONS This single-center study demonstrates that characterizing cardiac arrest in children undergoing cardiac surgery using definitions from 2 societies helps to increase data granularity and understand the relationship between cardiac arrest and heart operation in a better way.

Abstract
The objective of this study was to investigate the association between red blood cell (RBC) transfusion and hematocrit values with outcomes in infants undergoing Norwood operation. This study included infants ≤2 months of age who underwent Norwood operation with either a modified Blalock-Taussig shunt or a right ventricle-pulmonary artery shunt. Demographics, preoperative, operative, daily laboratory data, and postoperative variables were collected. The primary outcome measures evaluated included mortality, ICU length of stay, length of mechanical ventilation, and days to chest closure. The secondary outcome measures evaluated included lactate levels, estimated glomerular filtration rate, and inotrope score in the first 14 days after heart operation. Cox proportional hazard models were fitted to study the probability of study outcomes as a function of hematocrit values and RBC transfusions after operation. Eighty-nine patients qualified for inclusion. With a median hematocrit of 46 (IQR 44, 49), and a median RBC transfusion of 92 ml/kg (IQR 31, 384) in the first 14 days after operation, 81 (91 %) patients received RBC transfusions. A multivariable analysis adjusted for risk factors, including the age, weight, prematurity, cardiopulmonary bypass and cross-clamp time, and postoperative need for nitric oxide and dialysis, demonstrated no association between hematocrit and RBC transfusion with majority of study outcomes. This single-center study found that higher hematocrit values and increasing RBC transfusions are not associated with improved outcomes in infants undergoing Norwood operation.

Abstract
BACKGROUND There are very sparse data on the outcomes of children receiving prolonged extracorporeal membrane oxygenation (ECMO) after cardiac surgery. This study was aimed to evaluate the association of ECMO duration with outcomes in children undergoing surgery for congenital heart disease using the Pediatric Health Information System (PHIS) database. METHODS Patients aged ≤18 years receiving ECMO after pediatric cardiac surgery (with or without cardiopulmonary bypass) at a PHIS-participating hospital (2004-2013) were included. De-identified data obtained from retrospective, observational dataset included demographic information, baseline characteristics, pre-ECMO risk factors, operation details, patient diagnoses, and center data. Outcomes evaluated included in-hospital mortality, length of mechanical ventilation, length of ICU stay, length of hospital stay, and hospital charges. Cox proportional hazards models were fitted to study the probability of study outcomes as a function of ECMO duration. RESULTS Nine hundred ninety-eight patients from 37 hospitals qualified for inclusion. The median duration of ECMO run was 4 days (IQR: 1.7). After adjusting for patient and center characteristics, there was 12% increase in the odds of mortality for every 24 hours increase in ECMO duration (OR: 1.12, 95% CI: 1.07-1.18, P<0.001). Patients receiving longer duration of ECMO were associated with longer length of mechanical ventilation, longer length of ICU stay, longer length of hospital stay, and higher hospital charges. CONCLUSION Data from this large multicenter database suggest that longer duration of ECMO support after pediatric cardiac surgery is associated with worsening outcomes.

Abstract
BACKGROUND Little data exist regarding the association of presence of an invasive airway before cardiac arrest or early placement of an invasive airway after cardiac arrest with outcomes in children who experience in-hospital cardiac arrest. METHODS We conducted a retrospective review of patients aged 1 day to 18 years who received cardiopulmonary resuscitation (CPR) for ≥ 1 min in any of the three intensive care units (ICUs) at a tertiary care, academic children's hospital between 2002 and 2010. Specific outcomes evaluated included survival to hospital discharge, return of spontaneous circulation (ROSC), 24-h survival, and good neurological status at hospital discharge. We fitted multivariable logistic regression models to evaluate the association between the presence of an invasive airway prior to cardiac arrest and timing of placement of an invasive airway with these outcomes. RESULTS Three hundred and ninety-one patients were included. Of these, 197 (51%) patients were already tracheally intubated before the occurrence of cardiac arrest. Median time to intubation was 6 min [interquartile range (IQR): 2, 12] among the 194 patients tracheally intubated following cardiac arrest. We found lower survival to hospital discharge among patients intubated prior to cardiac arrest (intubated vs. non-intubated group, 43% vs. 61%, p < 0.001). After adjusting for patient and event characteristics, presence of an invasive airway prior to cardiac arrest was not associated with a significant improvement in survival to hospital discharge [odds ratio (OR): 0.70, 95% confidence interval (CI): 0.42-1.16, p = 0.17], or good neurological outcomes (OR: 0.60, 95% CI: 0.34-1.05, p = 0.07). Similarly, early placement of an invasive airway after cardiac arrest was also not associated with an improvement in survival to hospital discharge (OR: 1.05, 95% CI: 0.78-1.42, p = 0.73), or good neurological outcomes (OR: 1.08, 95% CI: 0.77-1.53, p = 0.65). CONCLUSIONS Our study demonstrates that presence of an invasive airway prior to cardiac arrest or early placement of an invasive airway after cardiac arrest is not associated with an improvement in survival to hospital discharge or good neurological outcomes. Further study of the relationship between invasive airway management and survival following cardiac arrest is warranted.

Abstract
The study objective was to evaluate outcomes among children with del22q11 (DiGeorge) syndrome supported on ECMO for heart disease. The ELSO registry database was queried to include all children <18 years undergoing heart surgery for either common atrio-ventricular canal, tetralogy of Fallot, truncus arteriosus or transposition of the great vessels and interrupted aortic arch and requiring ECMO, from 1998-2011. The outcomes evaluated included mortality, ECMO duration and length of hospital stay in patients with del22q11 syndrome and with no del22q11 syndrome. Eighty-eight ECMO runs occurred in children with del22q11 syndrome while 2694 ECMO runs occurred in children without del22q11 syndrome. For patients with heart defects receiving ECMO, del22q11 syndrome did not confer a significant mortality risk or an increased risk of infectious complications before or while on ECMO support. Neither the duration of ECMO nor mechanical ventilation prior to ECMO deployment were prolonged in patients with del22q11 syndrome compared to the controls.

Abstract
This study was initiated to assess the temporal trends of renal function, and define risk factors associated with worsening renal function in pediatric heart transplant recipients in the immediate post-operative period. We performed a single-center retrospective study in children ≤18 yr receiving OHT (1993-2012). The AKIN's validated, three-tiered AKI staging system was used to categorize the degree of WRF. One hundred sixty-four patients qualified for inclusion. Forty-seven patients (28%) were classified as having WRF after OHT. Nineteen patients (11%) required dialysis after heart transplantation. There was a sustained and steady improvement in renal function in children following heart transplantation in all age groups, irrespective of underlying disease process. The significant factors associated with risk of WRF included body surface area (OR: 1.89 for 0.5 unit increase, 95% CI: 1.29-2.76, p = 0.001) and use of ECMO prior to and/or after heart transplantation (OR: 3.50, 95% CI: 1.51-8.13, p = 0.004). Use of VAD prior to heart transplantation was not associated with WRF (OR: 0.50, 95% CI: 0.17-1.51, p = 0.22). On the basis of these data, we demonstrate that worsening renal function improves early after orthotopic heart transplantation.

Abstract
BACKGROUND This study was designed to evaluate the odds of mechanical ventilation and duration of mechanical ventilation after pediatric cardiac surgery across centers of varying center volume using the Virtual PICU Systems database. HYPOTHESIS Children receiving cardiac surgery at high-volume centers will be associated with lower odds of mechanical ventilation and shorter duration of mechanical ventilation, compared with low-volume centers. METHODS Patients age <18 years undergoing operations (with or without cardiopulmonary bypass) for congenital heart disease at one of the participating intensive care units in the Virtual PICU Systems database were included (2009-2013). Logistic regression models and Cox proportional hazards models were fitted for the probability of conventional mechanical ventilation and duration of mechanical ventilation, respectively, to investigate the difference in the outcomes between different center volume groups with/without adjustment for other risk factors. RESULTS A total of 10 378 patients from 43 centers qualified for inclusion. Of these, 7648 (74%) patients received conventional mechanical ventilation after cardiac surgery. Higher center volume was significantly associated with lower odds of mechanical ventilation after cardiac surgery (odds ratio: 2.68, 95% confidence interval: 2.15-3.35). However, patients receiving mechanical ventilation in these centers were associated with longer duration of mechanical ventilation, compared with lower-volume centers (hazard ratio: 1.26, 95% confidence interval: 1.16-1.37). This association was most prominent in the lower surgical-risk categories. CONCLUSIONS Large clinical practice variations were demonstrated for mechanical ventilation following pediatric cardiac surgery among intensive care units of varied center volumes.

Abstract
The objective of this study is to describe the incidence, etiologies, predictors, and outcomes of extubation failure in children undergoing orthotopic heart transplantation (OHT). A Retrospective, observational study was designed to evaluate clinical outcomes. . The study was conducted in a cardiovascular intensive care unit (CVICU) setting at a single, tertiary care, academic children's hospital. We collected demographic, pre-operative, intra-operative, post-operative and peri-extubation data in a retrospective, observational format from patients who underwent OHT at our institution. Clinical outcomes evaluated included the success or failure of extubation, CVICU length of stay (LOS), hospital LOS, and in-hospital mortality. We utilized descriptive and univariate statistics to compare the group with extubation failure to the group with extubation success. There were no interventions in this study. During the study period, 127 patients qualified for inclusion. The median age of patients was 108 months [interquartile range (IQR): 25-169] and median weight was 23 kg (IQR: 10.6-48). Extubation failure occurred in 12.5 % (16/127) of the patients. Median duration of mechanical ventilation was 2 days (IQR: 1-4.5), median CVICU LOS was 7 days (IQR: 5-13), and the median hospital LOS was 36 days (IQR: 20-74). Overall in-hospital mortality was 2 % (2/127). There was a significant improvement in blood pressure (p < 0.001) with a decrease in inotropic score (p < 0.001) after removal of positive pressure ventilation among the patients with extubation success. Independent factors associated with extubation failure included lower body weight, need for mechanical ventilation prior to heart transplantation, renal failure prior to extubation attempt, and right ventricular diastolic dysfunction prior to extubation attempt. Our study demonstrates that extubation failure in patients after OHT is infrequent and the causes are diverse. Extubation success in children after OHT is associated with improvement in mean arterial blood pressure, decrease in inotropic support, and decrease in supplemental oxygen requirement.

Abstract
OBJECTIVES Angiotensin converting enzyme inhibitors (ACEI) have been shown to decrease aortic growth velocity (AGV) in Marfan syndrome (MFS). We sought to compare the effect of β-blockers and ACEI on AGV in MFS. STUDY DESIGN We retrospectively reviewed all data from all patients with MFS seen at Arkansas Children's Hospital between January 1, 1976 and January 1, 2013. Generalized least squares were used to evaluate AGV over time as a function of age, medication group, and the interaction between the 2. A mixed model was used to compare AGV between medication groups as a function of age, medication group (none, β-blocker, ACEI), and the interaction between the 2. RESULTS A total of 67 patients with confirmed MFS were identified (34/67, 51% female). Mean age at first encounter was 13 ± 10 years, with mean follow-up of 7.6 ± 5.8 years. There were 839 patient encounters with a median of 10 (range 2-42) encounters per patient. AGV was nearly normal in the β-blocker group, and was less than either the ACEI or untreated groups. The AGV was higher than normal in ACEI and untreated groups (P < .001 for both). CONCLUSIONS β-blocker therapy results in near-normalization of AGV in MFS. ACEI did not decrease AGV in a clinically significant manner.

Abstract
The effects of extracorporeal membrane oxygenation (ECMO) support on renal function in children with critical illness are unknown. The objective of this study was to investigate the impact of ECMO on renal function among children in different age groups. We performed a single-center retrospective observational study in critically ill children ≤ 18 years supported on ECMO for refractory cardiac or pulmonary failure (2006-2012). The patient population was divided into four age groups for the purpose of comparisons. The Acute Kidney Injury Network's (AKIN's) validated, three-tiered staging system for acute kidney injury was used to categorize the degree of worsening renal function. Data on patient demographics, baseline characteristics, renal function parameters, dialysis, ultrafiltration, duration of mechanical cardiac support, and mortality were collected. Comparisons of baseline characteristics, duration of mechanical cardiac support, and renal function were made between the four age groups. During the study period, 311 patients qualified for inclusion, of whom 289 patients (94%) received venoarterial (VA) ECMO, 12 (4%) received venovenous (VV) ECMO, and 8 (3%) received both VV and VA ECMO. A total of 109 patients (36%) received ultrafiltration on ECMO, 58 (19%) received hemodialysis, and 51 (16%) received peritoneal dialysis. There was a steady and sustained improvement in renal function in all age groups during the ECMO run, with the maximum and longest-sustained improvement occurring in the oldest age group. Proportions of patients in different AKIN stages remained similar in the first 7 days after ECMO initiation. We demonstrate that renal dysfunction improves early after ECMO support. Irrespective of the underlying disease process or patient age, renal function improves in children with pulmonary or cardiac failure who are placed on ECMO.

Abstract
BACKGROUND Little is known about the relation between center volume and outcomes in children requiring intensive care unit (ICU) admission for acute asthma. OBJECTIVE To evaluate the association of center volume with the odds of receiving positive pressure ventilation and length of ICU stay. METHODS Patients 2 to 18 years of age with the primary diagnosis of asthma were included (2009-2012). Center volume was defined as the average number of mechanical ventilator cases per year for any diagnoses during the study period. In multivariable analysis, the odds of receiving positive pressure ventilation (invasive and noninvasive ventilation) and ICU length of stay were evaluated as a function of center volume. RESULTS Fifteen thousand eighty-three patients from 103 pediatric ICUs with the primary diagnosis of acute asthma met the inclusion criteria. Seven hundred fifty-two patients (5%) received conventional mechanical ventilation and 964 patients (6%) received noninvasive ventilation. In multivariable analysis, center volume was not associated with the odds of receiving any form of positive pressure ventilation in children with acute asthma, with the exception of high- to medium-volume centers. However, ICU length of stay varied with center volume and was noted to be longer in low-volume centers compared with medium- and high-volume centers. CONCLUSION In children with acute asthma, this study establishes a relation between center volume and ICU length of stay. However, this study fails to show any significant relation between center volume and the odds of receiving positive pressure ventilation; further analyses are needed to evaluate this relation in more detail.

Abstract
IMPORTANCE Outcomes associated with use of high-frequency oscillatory ventilation (HFOV) in children with acute respiratory failure have not been established. OBJECTIVE To compare the outcomes of HFOV with those of conventional mechanical ventilation (CMV) in children with acute respiratory failure. DESIGN, SETTING, AND PARTICIPANTS We performed a retrospective, observational study using deidentified data obtained from all consecutive patients receiving mechanical ventilation aged 1 month to 18 years in the Virtual PICU System database from January 1, 2009, through December 31, 2011. The study population was divided into 2 groups: HFOV and CMV. The HFOV group was further divided into early and late HFOV. Propensity score matching was performed as a 1-to-1 match of HFOV and CMV patients. A similar matching process was performed for early HFOV and CMV patients. EXPOSURE High-frequency oscillatory ventilation. MAIN OUTCOMES AND MEASURES Length of mechanical ventilation, intensive care unit (ICU) length of stay, ICU mortality, and standardized mortality ratio (SMR). RESULTS A total of 9177 patients from 98 hospitals qualified for inclusion. Of these, 902 (9.8%) received HFOV, whereas 8275 (90.2%) received CMV. A total of 1764 patients were matched to compare HFOV and CMV, whereas 942 patients were matched to compare early HFOV and CMV. Length of mechanical ventilation (CMV vs HFOV: 14.6 vs 20.3 days, P < .001; CMV vs early HFOV: 14.6 vs 15.9 days, P < .001), ICU length of stay (19.1 vs 24.9 days, P < .001; 19.3 vs 19.5 days, P = .03), and mortality (8.4% vs 17.3%, P < .001; 8.3% vs 18.1%, P < .001) were significantly higher in HFOV and early HFOV patients compared with CMV patients. The SMR in the HFOV group was 2.00 (95% CI, 1.71-2.35) compared with an SMR in the CMV group of 0.85 (95% CI, 0.68-1.07). The SMR in the early HFOV group was 1.62 (95% CI, 1.31-2.01) compared with an SMR in the CMV group of 0.76 (95% CI, 0.62-1.16). CONCLUSIONS AND RELEVANCE Application of HFOV and early HFOV compared with CMV in children with acute respiratory failure is associated with worse outcomes. The results of our study are similar to recently published studies in adults comparing these 2 modalities of ventilation for acute respiratory distress syndrome.

Abstract
BACKGROUND Effects of mechanical cardiac support on renal function in children with end-stage heart failure are unknown. The objective of this study was to investigate the impact of ventricular assist device (VAD) and extracorporeal membrane oxygenation (ECMO) on renal function in children. METHODS We performed a single center retrospective observational study in children with end-stage heart failure supported on pediatric mechanical cardiac support. The patient population was divided into three groups: the VAD group included patients receiving ventricular assist device support; the ECMO group included patients receiving extracorporeal membrane oxygenation membrane support for more than 14 days; and the ECMO+VAD group included patients receiving ECMO followed by VAD support. Comparison of baseline characteristics, duration of mechanical cardiac support, and renal function was made between the three groups. RESULTS During the study period, there were 23 patients in the VAD group, 16 patients in the ECMO+VAD group, and 37 patients in the ECMO group. The patients in the ECMO group were significantly younger and smaller than the patients in the VAD and ECMO+VAD groups. There was a steady improvement in eGFR in the VAD group and the ECMO+VAD group until day 7 after which there was a decline in renal function. In the ECMO group, the improvement in eGFR continued until day 28 after which there was a steady decline in eGFR. Improvement in eGFR in the VAD group and the ECMO+VAD group was much higher than in the ECMO group in the first 7 days. CONCLUSIONS On the basis of these data, we demonstrate that renal dysfunction improves early after mechanical cardiac support.

Abstract
This study aimed to identify the prevalence, etiology, and outcomes of extubation failure in children after complete repair for tetralogy of Fallot at a single tertiary-care, academic children's hospital. The secondary aim of this study was to determine the cardiorespiratory effects of the transition from positive-pressure ventilation to spontaneous breathing in children with extubation success and extubation failure. For this study, extubation was defined as the need for reintubation within 96 h after extubation. Demographics as well as pre-, intra-, post-, and periextubation data were collected in a retrospective observational format for patients who underwent complete repair for tetralogy of Fallot during the period January 2001-June 2011. Patients with multiple aortopulmonary collateral arteries or associated complete atrioventricular septal defects were excluded from the study. The cardiorespiratory variables collected before and immediately after extubation included heart rate, respiratory rate, mean arterial blood pressure, central venous pressures, near-infrared spectroscopy, oxygen saturations, and lactate levels. The clinical outcomes evaluated included the success or failure of extubation and the hospital length of stay. Descriptive and univariate statistics were used to compare the group with extubation failure and the group with extubation success. Extubation failure occurred for 7 % (12/164) of the 164 eligible patients during the study period. The median age of the patients at surgery was 200 days (range 98-356 days), and their median weight was 6.8 kg (range 5.2-8.5 kg). For 6 % (10/164) of the patients, intubation was performed before surgery. The median duration of mechanical ventilation was 33 h (range 19.5-73 h), and the median hospital stay was 10 days (range 7-15 days). Of the 12 patients with extubation failure, 2 had extubation failure in first 2 h after extubation, 6 had failure in 2-24 h, 3 had failure in 24-48 h, and 1 had failure in 48-96 h. The patients in the extubation success and extubation failure groups were similar in age, sex, and body weight at the time of surgery. All preexisting conditions also were similar in the two groups. The intraoperative variables and postoperative complications did not differ between the two groups. The hospital stay was longer for the children with extubation failure (p < 0.001). The partial pressure of oxygen in arterial blood (PaO2), tachycardia, mean arterial blood pressure, and inotrope score improved significantly at conversion from positive-pressure ventilation to spontaneous ventilation in the patients with extubation success. This study demonstrated that extubation failure in patients after complete repair for tetralogy of Fallot is low and that the etiology is diverse. The majority of extubation failures in these patients occurred in the first 24 h. Extubation success in the children after repair for tetralogy of Fallot was associated with improvement in PaO2, tachycardia, and mean arterial pressure, with a decrease in inotrope score. Extubation failure is associated with a longer hospital stay.

Abstract
OBJECTIVE There is cross-center variability with regard to timing repair of non-ductal-dependent tetralogy of Fallot (TOF). We hypothesized that earlier repair in the neonatal period is associated with increased mortality and morbidity. METHODS This was a retrospective analysis of the Pediatric Health Information System of tetralogy of Fallot patients undergoing complete repair from 2004 through 2010 between the ages of 1 day to younger than 19 years. Patients with pulmonary valve atresia, those who received prostaglandin during hospital admission, and those who underwent prior shunt palliation were excluded. RESULTS A total of 4698 patients met our inclusion criteria, of whom 202 were younger than 30 days old (group A), 861 were 31 to 90 days old (group B), 1796 were 91 to 180 days old (group C), and 1839 were older than 180 days (group D). In-hospital mortality, intensive care unit length of stay, and total hospital length of stay were significantly higher in group A. Patients in group A had a significantly increased postoperative requirement for mechanical ventilation, intravenous blood pressure support, medical diuresis, extracorporeal membrane oxygenation, gastrostomy tube insertion, heart catheterization, and surgical revision. Significant institutional variability was noted for timing of TOF complete repair, with one third of the centers performing 75% of the repairs at younger than 30 days old. The institutional approach to timing TOF complete repair showed no relation to surgical volume. CONCLUSIONS Across all centers analyzed, primary neonatal elective TOF repair (<30 days of age) is associated with significantly higher postoperative in-hospital morbidity and mortality, although a few centers have shown an ability to use this strategy with excellent survivability.

Abstract
This retrospective observational study aimed to evaluate the safety and efficacy of dexmedetomidine (DEX) for children with heart failure. The study was conducted in the cardiovascular intensive care unit (CVICU) of a single, tertiary care, academic children's hospital. A retrospective review of the charts for all children (up to 18 years of age) with signs and symptoms consistent with congestive heart failure who received DEX in our CVICU between April 2006 and April 2011 was performed. The patients were divided into two groups for study purposes: the DEX group of 21 patients, who received a DEX infusion together with other conventional sedation agents, and the control group of 23 patients, who received conventional sedation agents without the use of DEX. To evaluate the safety of DEX, physiologic data were collected including heart rate, mean arterial pressure (MAP), and inotrope score. To assess the efficacy of DEX, the amount and duration of concomitant sedation and analgesic infusions in both the DEX and control groups were examined. The numbers of rescue boluses for each category before the initiation of sedative infusion and during the sedative infusion also were examined. The baseline characteristics of the patients in the two groups were similar. There was no effect of DEX infusion on heart rate, MAP, or inotrope score at the termination of infusion. The daily amount of midazolam administered was significantly less during the last 24 h of DEX infusion in the DEX group than in the control group (p = 0.04). The daily amount of morphine infusion did not differ between the DEX and control groups during any period. The numbers of sedation and analgesic rescue boluses were lower in DEX group throughout the infusion. No other significant side effects were noted. Two patients in the DEX group had a 50 % or greater drop in MAP compared with baseline in the first 3 h after initiation of DEX infusion, whereas one patient had a 50 % or greater drop in heart rate compared with baseline in the first 3 h after initiation of DEX infusion. Administration of DEX for children with heart failure appears to be safe but should be used cautiously. Furthermore, DEX use is associated with a decreased opiate and benzodiazepine requirement for children with heart failure.

Abstract
The study aimed primarily to evaluate the efficacy of noninvasive ventilation (NIV) and to identify possible predictors for success of NIV therapy in preventing extubation failure in critically ill children with heart disease. The secondary objectives of this study were to assess the efficacy of prophylactic NIV therapy initiated immediately after tracheal extubation and to determine the characteristics, outcomes, and complications associated with NIV therapy in pediatric cardiac patients. A retrospective review examined the medical records of all children between the ages 1 day and 18 years who sustained acute respiratory failure (ARF) that required NIV in the cardiovascular intensive care unit (CVICU) at Lucile Packard Children's Hospital between January 2008 and June 2010. Patients were assigned to a prophylactic group if NIV was started directly after extubation and to a nonprophylactic group if NIV was started after signs and symptoms of ARF developed. Patients were designated as responders if they received NIV and did not require reintubation during their CVICU stay and nonresponders if they failed NIV and reintubation was performed. The data collected included demographic data, preexisting conditions, pre-event characteristics, event characteristics, and outcome data. The outcome data evaluated included success or failure of NIV, duration of NIV, CVICU length of stay (LOS), hospital LOS, and hospital mortality. The two complications of NIV assessed in the study included nasal bridge or forehead skin necrosis and pneumothorax. The 221 eligible events during the study period involved 172 responders (77.8 %) and 49 nonresponders (22.2 %). A total of 201 events experienced by the study cohort received continuous positive airway pressure (CPAP), with 156 responders (78 %), whereas 20 events received bilevel positive airway pressure (BiPAP), with 16 responders (80 %). In the study, 58 events (26.3 %) were assigned to the prophylactic group and 163 events (73.7 %) to the nonprophylactic group. Compared with the nonprophylactic group, the prophylactic group experienced significantly shorter CVICU LOS (median, 49 vs 88 days; p = 0.03) and hospital LOS (median, 60 vs 103 days; p = 0.05). The CVICU LOS and hospital LOS did not differ significantly between the responders (p = 0.56) and nonresponders (p = 0.88). Significant variables identifying a responder included a lower risk-adjusted classification for congenital heart surgery (RACHS-1) score (1-3), a good left ventricular ejection fraction, a normal respiratory rate (RR), normal or appropriate oxygen saturation, prophylactic or therapeutic glucocorticoid therapy within 24 h of NIV initiation, presence of atelectasis, fewer than two organ system dysfunctions, fewer days of intubation before extubation, no clinical or microbiologic evidence of sepsis, and no history of reactive airway disease. As a well-tolerated therapy, NIV can be safely and successfully applied in critically ill children with cardiac disease to prevent extubation failure. The independent predictors of NIV success include lower RACHS-1 classification, presence of atelectasis, steroid therapy received within 24 h after NIV, and normal heart rate and oxygen saturations demonstrated within 24 h after initiation of NIV.

Abstract
The primary objective of this study was to describe the impact of 22q11.2 deletion (del22q11) on the clinical characteristics, postoperative course, and short-term outcomes of children undergoing surgery for congenital heart disease. The charts of all children ages 1 day-18 years who received cardiac surgery for interrupted aortic arch (IAA), tetralogy of Fallot (TOF), or truncus arteriosus (TA) repair from 1 January 2001 to 31 December 2011 were retrospectively reviewed. The patients were divided into two groups: the 22q11 group including children with del22q11 undergoing surgery for TOF, IAA, or TA and the non-22q11 or control group including children with no chromosomal or genetic abnormality undergoing surgery for TOF, IAA, or TA. Demographic information, cardiac diagnoses, noncardiac abnormalities, preoperative factors, intraoperative details, surgical procedures performed, postoperative complications, and in-hospital deaths were collected. The outcome data collected included days of inotrope use, need for dialysis, length of mechanical ventilation, intensive care unit (ICU) length of stay (LOS), hospital LOS, and mortality. The study enrolled 173 patients: 65 patients in the 22q11 group and 108 patients in the control group. Of the 65 patients in the 22q11 group, 36 (55 %) underwent repair for TOF, 13 (20 %) for IAA, and 16 (25 %) for TA. The two groups did not differ in terms of age or weight. The preexisting conditions were similar in the two groups. Unplanned noncardiac operations were more common in the children with del22q11, but delayed chest closure was similar in the two groups. The incidence of postoperative noncardiac complications such as reintubation, vocal cord paralysis, and diaphragmatic paralysis was similar in the two groups. However, increasing numbers of patients in del22q11 group needed dialysis in one form or the other during the immediate postoperative stay. The incidence of fungal infection and wound infection was higher in the del22q11 group than in the control group. Duration of mechanical ventilation, ICU LOS, and hospital LOS were similar in the two groups, except in certain subgroups. Mortality did not differ significantly between the two groups. In conclusion, children with del22q11 have a higher risk of postoperative complications after cardiac surgery, with no difference in length of mechanical ventilation, ICU LOS, hospital LOS, or mortality. However, short-term outcomes may differ in certain subgroups.

Abstract
BACKGROUND Some neonates with tetralogy of Fallot (TOF) have rapid progression of right ventricular outflow tract obstruction, requiring early repair irrespective of Doppler gradient as measured in the neonatal period. The aim of this study was to test the hypothesis that infundibular morphology in neonates with TOF is associated with the occurrence of hypercyanotic spells and need for neonatal surgery. METHODS Fifty patients with TOF undergoing surgical repair from 2003 to 2009 were studied. Neonatal echocardiograms were retrospectively analyzed to measure conal septal angle (the angle between the conal septum and the horizontal plane passing through the center of the aortic valve in the parasternal short-axis view, with a larger angle denoting more anterocephalad deviation of conal septum), conal septal thickness and length, the degree of aortic dextroposition, and sizes and Z scores of the pulmonary annulus and the main and branch pulmonary arteries. Outcomes included the occurrence of hypercyanotic spells and the need for neonatal surgery. RESULTS The median age at first echocardiogram was 2 days (range, 0-12 days). The median age at surgery was 94 days (range, 5-282 days); hypercyanotic spells occurred in 17 patients (34%), and nine (18%) underwent neonatal repair. The presence of a wider conal septal angle was significantly associated with the occurrence of hypercyanotic spells (59 ± 21° vs 48 ± 13°, P = .023) and the need for neonatal surgery (67 ± 13° vs 48 ± 16°, P = .004). The positive and negative predictive values of hypercyanotic spells for conal septal angles ≥60° were 64% and 78%, respectively. Importantly, Doppler right ventricular outflow tract gradient at initial echocardiography, degree of aortic dextroposition, and pulmonary or aortic valve size were not associated with these outcomes. CONCLUSIONS A wider conal septal angle is associated with the occurrence of hypercyanotic spells and the need for neonatal surgery.

Abstract
OBJECTIVES Strain and strain rate imaging have been reported to detect cardiac dysfunction more accurately than conventional methods in adults with Marfan syndrome, but their utility has not been proven in younger patients. We sought to determine whether strain and strain rate imaging would allow early detection of cardiac dysfunction in children and young adults with Marfan syndrome. METHODS Unoperated patients (<30 years) with Marfan syndrome and healthy control participants were prospectively enrolled. Patients with greater than mild mitral or aortic insufficiency were excluded. Left ventricular systolic function was assessed by standard M-mode imaging. The strain and strain rate values were obtained from apical 4-chamber (longitudinal) and parasternal short-axis views at basal and midventricular levels (radial and circumferential). Data from the two groups were compared by a t test. RESULTS Sixteen patients with Marfan syndrome (mean age ± SD, 14.4 ± 6.4 years; range, 5.8-28.9 years) and 26 controls (mean age, 12.4 + 4.4 year; range, 4.1-18.1 years) were enrolled. Demographics and left ventricular end-diastolic dimensions were similar between the patients with Marfan syndrome and the controls. The M-mode-derived shortening fraction was significantly lower in the patients with Marfan syndrome compared to the controls, even though the values were within normal limits. The patients with Marfan syndrome had lower regional radial and circumferential strain rates, but there were no significant difference in strain between the groups. CONCLUSIONS Strain rate imaging may be useful in detection of subclinical changes in cardiac function in patients with Marfan syndrome when conventional echocardiographic parameters are within normal limits. These findings may be clinically important and warrant closer follow-up of these patients to monitor for cardiac dysfunction.

Abstract
The primary objective of this study was to evaluate the hemodynamic effects of dexmedetomidine (DEX) infusion on critically ill neonates and infants with congenital heart disease (CHD). The secondary objective of the study was to evaluate the safety and efficacy profile of the drug in this patient population. A retrospective observational study was conducted in the cardiovascular intensive care unit (CVICU) of a single tertiary care university children's hospital. The charts of all neonates and infants who received DEX in the authors' pediatric CVICU between August 2009 and June 2010 were retrospectively reviewed. The demographic data collected included age, weight, sex, diagnosis, and Risk Adjustment in Congenital Heart Surgery (RACHS-1) score. To evaluate the hemodynamic effects of DEX, physiologic data were collected including heart rate, mean arterial pressure (MAP), inotrope score, near-infrared spectroscopy, and central venous pressure (CVP). To assess the efficacy of DEX, the amount and duration of concomitant sedation and analgesic infusions over a period of 24 h were examined together with the number of rescue boluses. The potential side effects evaluated in this study included nausea, vomiting, abdominal distension, dysrhythmias, neurologic abnormalities, seizures, and signs and symptoms of withdrawal. During the study period, 50 neonates and infants received DEX for a median period of 78 h (range, 40-290 h). These patients had an average age of 3.53 ± 2.64 months and a weight of 4.85 ± 1.67 kg. Whereas 34 patients (68%) received DEX after surgery for CHD, 15 patients (30%) received DEX after heart transplantation. Of these 50 infants, 10 (20%) had a single-ventricle anatomy, whereas 13 (26%) had a risk adjustment score (RACHS-1) in the category of 4-6. The median CVICU stay was 29 days (range, 8-69 days). Despite a significant decrease in heart rate, MAP, inotrope score, and CVP, all the patients remained hemodynamically stable during DEX infusion. There was no substantial difference in major hemodynamic variables between neonates and infants, single- and two-ventricle repair, RACHS 4-6 and RACHS 1-3 categories for patients undergoing surgery, or patients undergoing heart transplantation and patients undergoing other surgical procedures. Dexmedetomidine infusion for neonates and infants with heart disease is safe from a hemodynamic standpoint and can reduce the concomitant dosing of opioid and benzodiazepine agents. Furthermore, DEX infusion may be useful for reducing vasopressor agent dosing in children with catecholamine-refractory cardiogenic shock.

Abstract
OBJECTIVE The objectives of this study were (1) to determine the use of temporary epicardial pacing wires to diagnose and treat early postoperative arrhythmias in pediatric cardiac surgical patients and (2) to determine the predictive factors for the need of pacing wires for diagnostic or therapeutic purposes. METHODS We collected preoperative, intraoperative, and postoperative data in a prospective, observational format from patients undergoing pediatric cardiac surgery between August 2010 and January 2011 at a single academic children's hospital. RESULTS A total of 157 patients met the inclusion criteria during the study period. Of these 157 patients, pacing wires were placed in 127 (81%). Pacing wires were used in 25 patients (19.6%) for diagnostic purposes, 26 patients (20.4%) for therapeutic purposes, 15 patients (11.8%) for both diagnostic and therapeutic purposes, and 36 patients (28.3%) for diagnostic or therapeutic purposes. Need for cardioversion in the operating room, presence of 2 or more intracardiac catheters, severely reduced ventricular ejection fraction, and elevated serum lactate level at the time of operating room discharge were found to be independent predictors for the use of pacing wires. The only complication noted in the cohort was a skin infection at a pacing wire insertion site in 1 patient. A permanent pacemaker was required in 8 (6.2%) of all patients with temporary pacing wires. CONCLUSIONS Our data support the use of temporary epicardial pacing wires in approximately 30% of children after congenital heart surgery. We found the need for cardioversion in the operating room, presence of 2 or more intracardiac catheters, severely reduced ventricular ejection fraction, and high serum lactate level at the time of discharge from the operating room to be independent predictors of the use of pacing wires in the early postoperative period.
