Abstract
PURPOSE The aim of the study was to analyze the surgical outcome of patients with total anomalous pulmonary venous connection (TAPVC) who underwent cardiac surgery. METHODS A retrospective study was carried out. Patients with diagnosis of TAPVC undergoing cardiac surgery at the National Institute of Cardiology Ignacio Chávez, from January 1, 2003 and June 30, 2019 were included. Descriptive statistics were calculated, as well as a bivariate analysis of the variables associated with mortality. A logistic regression model was included to determine risk factors associated with the main outcome and survival was analyzed using the Kaplan-Meier method. RESULTS A total of 5314 patients diagnosed with congenital heart disease (CHD) underwent surgery, 414 (7.8%) were patients with TAPVC, with an average age of 17.1 ± 34.6 months, 58.2% were male. It was frequent in infants (61.6%) and preschool (19.6%). Predominant type was supracardiac TAPVC (47.4%). Pulmonary venous obstruction (PVO) occurred in 32.1%. Risk factors associated with mortality were infracardiac TAPVC (odds ratio [OR]: 3.26; 95% confidence interval [CI]: 1.17-9.03; p = .02), PVO (OR: 2.56; 95% CI: 1.05-6.22; p = .03) and postoperative mechanical ventilation (OR: 1.005; 95% CI: 1.002-1.008; p = .01). Overall survival was 87.2%, with better outcomes in adolescents (100%), children (94.1%), mixed TAPVC (96%), and cardiac TAPVC (91.9%; p < .001). CONCLUSIONS The survival of our institution after surgical correction of TAPVC is similar to that of other referral centers, where patients with infracardiac TAPVC and newborns worse outcomes. All patients must undergo a rigorous evaluation to determine an adequate repair strategy.

Abstract
OBJECTIVE To summarize existing literature on neonatal disparities in congenital heart disease surgical outcomes and identify potential policies to address these disparities. FINDING Disparities in outcomes for neonatal congenital heart surgery were largely published under four domains: race/ethnicity, insurance type, neighborhood/socioeconomic status, and cardiac center characteristics. While existing research identifies associations between these domains and mortality, more nuanced analyses are emerging to understand the mediators between these domains and other non-mortality outcomes, as well as potential interventions and policies to reduce disparities. A broader look into social determinants of health (SDOH), prenatal diagnosis, proximity of birth to a cardiac surgical center, and post-surgical outpatient and neurodevelopmental follow-up may accelerate interventions to mitigate disparities in outcomes. CONCLUSION Understanding the mechanisms of how SDOH relate to neonatal surgical outcomes is paramount, as disparities research in neonatal congenital heart surgery continues to shift from identification and description, to intervention and policy.

Abstract
OBJECTIVES To demonstrate that improvement in technical performance of congenital heart surgical trainees during ventricular septal defect(VSD) closure simulation translates to better patient outcomes. METHODS Seven trainees were divided into two groups. Experienced-fellows group included four senior trainees who had performed>five VSD closures. Residents group consisted of three residents who had never performed a VSD closure. Experienced-fellows completed 3 VSD closures on real patients as a pretest. Both groups participated in a four-week simulation requiring each participant to complete two VSD closures on 3D-printed models per week. One-month later all trainees returned for a posttest operation in real patients. All performances were recorded, blinded and scored independently by two cardiac surgeons using the validated Hands-On Surgical Training-Congenital Heart Surgery(HOST-CHS). Predefined surgical outcomes were analyzed. RESULTS The median HOST-CHS score increased significantly from week one to four [50(39,58) vs.73(65,74), p < 0.001] during simulation. The improvement in the simulation of experienced-fellows successfully transferred to skill acquisition[HOST-CHS score 72.5(71, 74)vs.54(51, 60), p < 0.001], with better patients outcomes including shorter total cross-clamp time[pretest: 86(70,99) vs.posttest: 60(53, 64) min, p = 0.006], and reduced incidence of major patch leak requiring multiple pump runs[pretest: 4/11vs.posttest: 0/9, p = 0.043]. After simulation, the technical performance and surgical outcomes of residents were comparable to experienced-fellows in real patients, except for significantly longer cross-clamp time[Residents : 76.5(71.7,86.8)vs.Experienced-fellows : 60(53,64) min, p = 0.002]. CONCLUSIONS Deliberate practice using simulation translates to better performance and surgical outcomes in real patients. Residents who had never completed a VSD closure could perform the procedures just as safely and effectively as their senior colleagues following simulation.

Abstract
BACKGROUND Institutional survival following Norwood procedures is traditionally correlated with a center's surgical volume. Multiple single and multi-institutional studies conducted at large-volume centers have recently demonstrated improved survival following Norwood procedures. We report both short- and long-term outcomes at a single, small-volume institution and comment on factors potentially influencing outcomes at this institution. METHODS All patients undergoing Norwood procedures from January 1, 2005, to January 1, 2020, at our institution were included in this study. Kaplan-Meier survival and Cox regression risk factor analyses were performed in addition to first interstage risk factor scoring to compare observed versus expected survival. RESULTS The cohort included 113 patients. Kaplan-Meier freedom from death or transplant was 88%, 80%, and 76% at 1, 5, and 10 years, respectively. Freedom from death following hospital discharge after Norwood procedures was 94%, 87%, and 83% at 1, 5, and 10 years, respectively. The presence of genetic syndromes was a significant risk factor for mortality. First interstage observed-to-expected mortality following discharge was 0.57 (P = .04). Postoperative length of stay was comparable to that reported for the period 2015 to 2018 in the Society of Thoracic Surgeons Database. CONCLUSIONS Survival outcomes at this single, small-volume institution were similar to those reported by large-volume centers and multi-institutional collaborative studies. These results may be related to structural and functional features that have been demonstrated to influence outcomes in other studies. These factors are achievable by small-volume programs with sufficient resource allocation.

Abstract
A 6-month-old boy, a case of Shone's complex, presented in decompensated state was found to have severe mitral stenosis along with multisystem inflammatory syndrome in children (MISC) warranting urgent surgical intervention. Various modalities including cytokine-adsorbing hemofilter were used to target inflammation. Postoperatively, the child recovered from low cardiac output accompanied by decrease in the levels of inflammatory markers, inopressors, and ventilatory requirements. Open heart surgery in itself is a proinflammatory process and is best avoided during the active inflammatory phase of MISC. In the rare and unavoidable circumstance exemplified by this index case, multipronged strategy targeting inflammation as described can be successfully implemented.

Abstract
OBJECTIVE The use of nicardipine in congenital cardiac surgery has been guarded given the calcium sensitivity of immature myocardium and paucity of clinical data. Reports of nicardipine use have excluded neonates with single ventricles. The goal of this study was to compare the use of nicardipine and sodium nitroprusside for postoperative blood pressure control in young patients recovering from cardiac surgery. METHODS All neonates (<30 days) and young infants (31-180 days) who received either sodium nitroprusside or nicardipine as first-line therapy for blood pressure control were retrospectively reviewed. Some patients had multiple index operations and each index operation was counted separately regarding treatment with sodium nitroprusside or nicardipine. RESULTS A total of 59 patients underwent 70 procedures (24 as neonates and 46 as infants). Nicardipine was administered as initial therapy following 33 procedures (n = 28 patients), and sodium nitroprusside was administered as initial therapy following 37 index procedures (n = 31 patients). The duration of treatment was longer (P = .025) when sodium nitroprusside was the initial treatment. Five (15%) patients that received nicardipine required a second blood pressure management agent, and seven (19%) patients that received sodium nitroprusside required a second agent (P = .66). No adverse events related to titratable antihypertensive therapy were recorded in any treatment group. The use of nicardipine resulted in significant medication cost reduction. Based on average wholesale price, patient costs for sodium nitroprusside use were $182,952 ($5,544/pt), while costs for nicardipine were only $24,960 ($780/pt). CONCLUSIONS Nicardipine can be safely used as a first-line antihypertensive in infants. The use of nicardipine as initial antihypertensive therapy rather than sodium nitroprusside can lead to a significant reduction in medication costs without jeopardizing clinical outcomes.

Abstract
BACKGROUND Supravalvar aortic stenosis (SVAS) may be an isolated defect of the proximal ascending aorta. However, more severe cases have extension of the arteriopathy into the transverse and proximal descending aorta. The purpose of this study was to review our experience with SVAS with and without aortic arch arteriopathy. METHODS This was a retrospective review of 58 patients who underwent surgical repair of SVAS. The median age at repair was 18 months. A total of 37 patients had Williams syndrome. A total of 31 (53%) patients had associated peripheral pulmonary artery stenosis and 23 (39%) had coronary artery ostial stenosis (CAOS). RESULTS A total of 37 of 58 (64%) patients had surgical repair of SVAS without the need for arch intervention while 21 (36%) patients had repair of the distal aortic arch. There were 3 (5.2%) operative deaths, 2 of whom had aortic arch involvement and one without arch involvement. There were 2 deaths after discharge from the hospital. Patients who needed arch surgery were more likely to have severe arch gradients compared to those without arch involvement (71% vs 30%, P < .05), were more likely to undergo concomitant procedures for peripheral pulmonary artery stenosis or CAOS (90% vs 62%, P < .05), and to have Williams syndrome (86% vs 51%, P < .05). CONCLUSIONS More than one-third of patients who had SVAS repair at our institution had procedures directed at the transverse or proximal descending aorta. Patients with arch involvement had more severe arch obstruction, required more concomitant procedures, and were more likely to have Williams syndrome.

Abstract
The use of a peritoneal catheter in selected patients, in relation to the congenital heart defect and surgical procedure, may improve postoperative fluid balance and recovery. The peritoneal catheter allows to either drain ascites passively out of the peritoneal cavity or utilize cycles of peritoneal dialysis. However, potential benefits contrast with risk. This article provides a step-by-step guide on how to implant a peritoneal catheter in the operating room after cardiac surgery, or insert it at the bedside in the ICU, to minimize the risk of complications such as bowel perforation, herniation or omental adhesions.

Abstract
BACKGROUND Extubation early in the postoperative period is beneficial to the recovery and rehabilitation of patients. This study compared the postoperative extubation failure rates among infants who received postextubation respiratory support by either bi-level positive airway pressure (BPAP) or nasal CPAP following cardiac surgery. METHODS This was a single-center randomized controlled trial registered at the Chinese Clinical Trial Registry (number ChiCTR2000041453) and was conducted between January 2020 and March 2021. Ventilated infants who underwent cardiac surgery were randomized to either a BPAP or a nasal CPAP group for ventilatory support following extubation. The primary outcome measure was the extubation failure rate within 48 h. RESULTS The analyses included 186 subjects. Treatment failure necessitating re-intubation was noted in 14 of the 93 infants (15%) in the BPAP group and in 11 of the 93 infants (12%) in the nasal CPAP group (P = .52). Moreover, there were no statistically significant differences between the 2 groups regarding the duration of noninvasive ventilation (P = .54), total enteral feeding time (P = .59), or complications (P = .85). We found that both the BPAP group and the nasal CPAP group showed significantly improved oxygenation and relief of respiratory distress after treatment. However, the PaCO2 level within 24 h was significantly lower in the BPAP group (P = .001) than in the CPAP group. Additionally, the PaO2 /FIO2 in the BPAP group was significantly higher than in the nasal CPAP group at 6 h, 12 h, and 24 h after treatment (P < .001). CONCLUSIONS The introduction of BPAP for postextubation respiratory support was not inferior to nasal CPAP in infants after cardiac surgery. Moreover, BPAP was shown to be superior to nasal CPAP in improving oxygenation and carbon dioxide clearance.

Abstract
We aimed to describe the longitudinal risk of advanced heart failure (HF) leading to death, heart transplantation, or ventricular assist device (VAD) placement after congenital heart surgery (CHS) and how it varies across the spectrum of congenital heart disease. We linked the records of patients who underwent first CHS in the Pediatric Cardiac Care Consortium between 1982 and 2003 with the United States National Death Index and Organ Procurement and Transplantation Network databases. Primary outcome was time from CHS discharge to HF-related death, heart transplant, or VAD placement, analyzed with proportional hazards models accounting for competing mortality. In 35,610 patients who survived a first CHS, there were 799 HF deaths, transplants, or VADs over a median of 23 years (interquartile range, 19 to 27). Cumulative incidence at 25 years was 2.3% (95% confidence interval [CI] 2.1% to 2.4%). Compared to mild 2-ventricle defects, the adjusted subhazard ratio for moderate and severe 2-ventricle defects was 3.21 (95% CI 2.28 to 4.52) and 9.46 (95% CI 6.71 to 13.3), respectively, and for single-ventricle defects 31.8 (95% CI 22.2 to 45.6). Systemic right ventricle carried the highest risk 2 years after CHS (subhazard ratio 2.76 [95% CI 2.08 to 3.68]). All groups had higher rates of HF-related death compared with the general population (cause-specific standardized mortality ratio 56.1 [95% CI 51.0 to 61.2]). In conclusion, the risk of advanced HF leading to death, transplantation, or VAD was high across the spectrum of congenital heart disease. While severe defects carry the highest risk, those with mild disease are still at greater risk than the general population.

Abstract
Background:Reliable prediction of severe acute kidney injury (AKI) and related poor outcomes has the potential to optimize treatment. The purpose of this study was to modify the renal angina index in pediatric cardiac surgery to predict severe AKI and related poor outcomes. Methods: We performed a multicenter retrospective study with the population divided into a derivation and validation cohort to assess the performance of a modified renal angina index assessed at 8 h after cardiac intensive care unit (CICU) admission to predict a complex outcome of severe day 3 AKI or related poor outcomes (ventilation duration >7 days, CICU length of stay >14 days, and mortality). The derivation sample was used to determine the optimal cut-off value. Results: There were 298 and 299 patients in the derivation and validation cohorts, respectively. The incidence of severe day 3 AKI and the complex outcome was 1.7% and 28% in the derivation and validation cohort. The sensitivity analysis for fulfillment of renal angina was a score >8 with a sensitivity of 63%, specificity of 73%, and negative predictive value of 83%. The cardiac renal angina index predicted the composite outcome with an area under the curve of 0.7 (95% confidence interval: 0.62-0.78). Renal angina patients had a significantly higher probability of the complex outcome when compared to individual risk and injury categories. Conclusions: We operationalized the renal angina index for use after cardiac surgery. Further revision and modification of the construct with integration of biomarkers in a prospective cohort are necessary to refine the prediction model.

Abstract
INTRODUCTION While frequently performed in the adult population, percutaneous coronary artery stent angioplasty (CSA) in infants is rare. CSA in infants is challenging because of limited options in terms of appropriately sized (length and diameter) stents, concern about stenting vessels with significant growth potential and limited data regarding durability of benefit. We report a multicenter case series of infants who underwent CSA. METHODS A multicenter, retrospective case series of infants who underwent percutaneous CSA to treat post-operative coronary artery stenoses was performed. RESULTS Six infants from 3 institutions who underwent post-operative CSA were identified. The anatomic diagnoses were d-transposition of the great arteries in 3 cases, anomalous left coronary artery from the pulmonary artery in 2 and supravalvar aortic stenosis in 1. All infants were critically ill at the time of CSA. Diameters of coronary artery stents used ranged from 2.25 to 2.75 mm. There were no procedural complications. All stents were patent immediately after placement and the clinical condition improved or stabilized in all patients. Follow-up angiography was available for 3 patients at 4 to 16 months post-CSA, at which time 67% (2/3) remained patent. CONCLUSION CSA is a feasible and effective therapy for critically ill infants with post-surgical coronary obstruction. Treatment appears to allow at least short-term reperfusion to facilitate recovery of ventricular function and potential development of collateral circulation when longer-term stent patency is not achieved. Longer-term stent patency and coronary artery health remain unanswered questions.

Abstract
INTRODUCTION Our aim was to present the initial experience with a protocol-driven early extubation strategy and to identify risk factors associated with failed spontaneous breathing trials within 12 hours after surgery. METHODS A single institutional retrospective study of children up to 18 years of age was conducted in post-operative cardiac surgical patients over a 1-year period. A daily spontaneous breathing trial protocol was used to assess patients' readiness for extubation. The study population (n = 129) was stratified into two age groups: infants (n = 84) and children (n = 45), and further stratified according to ventilation time: early extubation (ventilation time less than 12 h, n = 86) and deferred extubation (ventilation time more than 12 h, n = 43). Mann-Whitney U-test and binomial logistic regression were used for statistical analysis. RESULTS Early extubated infants had shorter ICU (4 versus 6 days, p = 0.003) and hospital length of stays (16 versus 19 days, p = 0.006), lower re-intubation rates (1 versus 7 patients, p = 0.003), and lower mortality (0 versus. 4 patients, p = 0.01) than deferred extubated infants. There was no significant difference in the studied outcomes in the children group. Malnourished infants and longer cardiopulmonary bypass times were independently associated with failed spontaneous breathing trials within 12 hours after cardiac surgery. CONCLUSIONS Early extubated infants after cardiac surgery had shorter ICU and hospital length of stay, without an increase in morbidity and mortality, compared to infants who deferred extubation. Nutritional status and longer cardiopulmonary bypass times were risk factors for failed spontaneous breathing trial.

Abstract
Operative mortality after repair of congenital heart disease has improved dramatically over the past few decades. Nevertheless, there is always room for the additional mitigation of complications and mortality. Being able to anticipate adverse outcomes is clearly important, especially when using low-cost and easily accessible resources. The neutrophil-lymphocyte ratio (NLR) is defined as the ratio of the absolute neutrophil to lymphocyte count, which can be easily measured using a regular white blood cell count. Recently, preoperative NLR has been shown to be a predictor of outcomes in patients undergoing congenital heart surgery. Although it presented promising results, there are still many gaps to be filled like the normal value for children, the ideal cutoff value to predict adverse outcomes, the wide variation and its correlation with other biomarkers, and if it is a modifiable risk factor. The aim of this review is to understand the prognostic value of preoperative NLR as a biomarker predictor of outcomes in patients undergoing congenital heart surgery based on previous clinical studies and to propose future directions in order to solve the above-mentioned questions.

Abstract
Significant progress has been made in neonatal cardiopulmonary bypass (CPB) over the years. At Penn State Health Children's Hospital, we have established a multidisciplinary research team that brings clinicians, engineers, scientists, research nurses, neuromonitoring technicians, perfusionists, and students from various departments to help reduce adverse outcomes following CPB in neonates. With the help of this team, we evaluate each CPB component in simulated conditions identical to those used in clinical practice. The objective of this review is to demonstrate the results of these translational projects and present critical mistakes to avoid for neonatal CPB patients.

Risk Stratification for Congenital Heart Surgery for ICD-10 Administrative Data (RACHS-2). J Am Coll Cardiol 2022; 79:465-478. [PMID: 35115103 PMCID: PMC8962919 DOI: 10.1016/j.jacc.2021.11.036] [Citation(s) in RCA: 12] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/08/2021] [Revised: 11/01/2021] [Accepted: 11/08/2021] [Indexed: 11/23/2022]
Abstract
BACKGROUND As the cardiac community strives to improve outcomes, accurate methods of risk stratification are imperative. Since adoption of International Classification of Disease-10th Revision (ICD-10) in 2015, there is no published method for congenital heart surgery risk stratification for administrative data. OBJECTIVES This study sought to develop an empirically derived, publicly available Risk Stratification for Congenital Heart Surgery (RACHS-2) tool for ICD-10 administrative data. METHODS The RACHS-2 stratification system was iteratively and empirically refined in a training dataset of Pediatric Health Information Systems claims to optimize sensitivity and specificity compared with corresponding locally held Society of Thoracic Surgeons-Congenital Heart Surgery (STS-CHS) clinical registry data. The tool was validated in a second administrative data source: New York State Medicaid claims. Logistic regression was used to compare the ability of RACHS-2 in administrative data to predict operative mortality vs STAT Mortality Categories in registry data. RESULTS The RACHS-2 system captured 99.6% of total congenital heart surgery registry cases, with 1.0% false positives. RACHS-2 predicted operative mortality in both training and validation administrative datasets similarly to STAT Mortality Categories in registry data. C-statistics for models for operative mortality in training and validation administrative datasets-adjusted for RACHS-2-were 0.76 and 0.84 (95% CI: 0.72-0.80 and 0.80-0.89); C-statistics for models for operative mortality-adjusted for STAT Mortality Categories-in corresponding clinical registry data were 0.75 and 0.84 (95% CI: 0.71-0.79 and 0.79-0.89). CONCLUSIONS RACHS-2 is a risk stratification system for pediatric cardiac surgery for ICD-10 administrative data, validated in 2 administrative-registry-linked datasets. Statistical code is publicly available upon request.

Abstract
Background The ratio of early diastolic mitral inflow velocity (E) to early diastolic mitral annular tissue velocity (e’), or E/e’, is an echocardiographic measure of left ventricular filling pressure. Peri‐operative changes in E/e’ and association with outcomes have been demonstrated in adults undergoing surgery for aortic stenosis (AS). We sought to explore changes in E/e’ and other diastolic indices in the setting of congenital AS surgery and to assess for association with post‐operative outcomes among children and young adults. Methods A retrospective, single‐center study was performed among patients 6 months to 30 years of age who underwent congenital AS surgery from 2006 to 2018. Tissue Doppler indices were collected from pre‐ and post‐operative echocardiograms. Post‐operative outcomes were reviewed. Results Sixty‐six subjects with subvalvar (45%), valvar (47%), and supravalvar (8%) AS underwent surgery at a median age of 9.5 years (IQR: 4.0–14.8). Pre‐operatively, the lateral E/e’ ratio was 8.6 (6.7–11.0); 33% had E/e’≥10. Post‐operatively, the lateral e’ decreased to 9.9 cm/s (8.0–11.4), the E/e’ ratio increased to 10.4 (8.3–13.1); and 53% had E/e’≥10 (p‐values < 0.0001, 0.0072, and < 0.001, respectively). Pre‐operative lateral e’ correlated modestly with duration of intubation (ρ = −0.24, p‐value 0.048) and post‐operative lateral e’ correlated modestly with duration of intubation and length of hospital stay (ρ = −0.28 and −0.26, p‐values = 0.02 and 0.04, respectively). Conclusions Children and young adults who underwent congenital AS surgery had echocardiographic evidence of diastolic dysfunction pre‐operatively that worsened post‐operatively. Lateral e’ may be a sensitive indicator of impaired ventricular relaxation in these patients and may impact duration of intubation and hospital stay.

Abstract
Coronavirus disease 2019 causes respiratory and systemic disease and has led to a sudden epidemic affecting people of all ages. Patients with congenital heart disease represent a high-risk population. In this article, we present a newborn who required extracorporeal membrane oxygenation support for acute respiratory failure in the early postoperative period due to exposure to severe acute respiratory syndrome coronavirus 2 after aortic arch repair and ventricular septal defect closure. To the best of our knowledge, this patient represents the first neonatal case of severe acute respiratory syndrome coronavirus 2 infection after congenital heart surgery and is the youngest patient to need extracorporeal membrane oxygenation support.

Front Pediatr 2022; 10:915045. [PMID: 36268038 PMCID: PMC9576841 DOI: 10.3389/fped.2022.915045] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/07/2022] [Accepted: 08/26/2022] [Indexed: 11/25/2022] Open
Abstract
BACKGROUND Meta-analysis of the impact on clinical outcome from transcatheter closure of Fontan fenestration. METHODS Cochrane, Embase, MEDLINE, and Open-Gray were searched. Parameters such as changes in oxygen saturation, cavo-pulmonary pressure, maximum heart rate during exercise, exercise duration, and oxygen saturation after fenestration closure were pooled and statistical analysis performed. RESULTS Among 922 publications, 12 retrospective observational studies were included. The included studies involved 610 patients, of which 552 patients (90.5%) had a fenestration. Of those patients, 505 patients (91.5%) underwent attempt at trans-catheter closure. When it could be estimated, the pooled overall mean age at trans-catheter fenestration closure was 6.6 ± 7.4 years, and the mean follow-up time was 34.4 ± 10.7 months. There were 32 minor (6.3%) and 20 major (4.0%) complications during or after trans-catheter Fontan fenestration closure. The forest plots demonstrate that following fenestration closure, there was a significant increase in the mean arterial oxygen saturation of 7.9% (95% CI 6.4-9.4%, p < 0.01). There was also a significant increase in the mean cavo-pulmonary pressure of 1.4 mmHg (95% CI 1.0-1.8 mmHg, p < 0.01) following fenestration closure. The exercise parameters reported in 3 studies also favored closing the fenestration as well, yet the exercise duration increase of 1.7 min (95% CI 0.7-2.8 min, p < 0.01) after fenestration closure is probably clinically insignificant. CONCLUSION Late closure of a Fontan fenestration has the impact of improving resting oxygen saturation, exercise oxygen saturation, and a modest improvement of exercise duration. These clinical benefits, however, may be at the expense of tolerating slightly higher cavo-pulmonary mean pressures.

Pediatr Int 2022; 64:e15270. [PMID: 36239168 DOI: 10.1111/ped.15270] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/10/2021] [Revised: 04/09/2022] [Accepted: 06/06/2022] [Indexed: 11/29/2022]
Abstract
BACKGROUND We aimed to compare the frequency of acute kidney injury (AKI) and its effects on mortality and morbidity with different classification systems in pediatric patients who had surgery under cardiopulmonary bypass for congenital heart disease. METHODS This study included children younger than 18 years old who were followed up in the pediatric cardiac intensive care unit between September 1 and December 1, 2020, after congenital heart surgery with cardiopulmonary bypass. Each case was categorized postoperatively in terms of AKI using Pediatric-Modified Risk, Injury, Failure, Loss, and End-Stage (pRIFLE), Acute Kidney Injury Network (AKIN), and Kidney Disease: Improving Global Outcomes (KDIGO). Hospital mortality (developed within the first 30 days postoperatively) and morbidity (longer than 7 days intensive care unit stay) were compared by three model classes. Results were evaluated statistically. RESULTS One hundred patients were included in the study. The median age was 3 months (1 day-180 months). Acute kidney injury was diagnosed in 49% of the cases according to the pRIFLE classification. It was diagnosed in 31% of the patients by AKIN classification. It was diagnosed in 41% of the patients with the KDIGO criteria. Morbidity was observed in 25% (n = 25) of all cases. The morbidity predictor was 0.800 for pRIFLE, 0.747 for AKIN and 0.853 for KDIGO by receiver operating characteristics analysis. All three categories predicted morbidity significantly (P < 0.001). Mortality was 10% (n = 10) for all groups. The mortality predictor was 0.783 for pRIFLE, 0.717 for AKIN and 0.794 for KDIGO by receiver operating characteristics analysis, and all three categories predicted mortality significantly (P < 0.001). CONCLUSIONS Regardless of the three methods used, AKI was commonly detected in pediatric patients undergoing congenital heart surgery. pRIFLE classification diagnosed more patients with AKI than AKIN and KDIGO. The KDIGO and pRIFLE classifications were better in predicting hospital mortality.

Curr Cardiol Rev 2022; 18:e030621193817. [PMID: 34082685 PMCID: PMC9241111 DOI: 10.2174/1573403x17666210603113430] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/30/2020] [Revised: 01/22/2021] [Accepted: 02/27/2021] [Indexed: 11/22/2022] Open
Abstract
BACKGROUND Junctional Ectopic Tachycardia (JET) is an arrhythmia originating from the AV junction, which may occur following congenital heart surgery, especially when the intervention is near the atrioventricular junction. OBJECTIVE The aim of this systematic review and meta-analysis is to compare the effectiveness of amiodarone, dexmedetomidine, and magnesium in preventing JET following congenital heart surgery. METHODS This meta-analysis was conducted according to the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) statement, where 11 electronic databases were searched from the date of inception to August 2020. The incidence of JET was calculated with the relative risk of 95% Confidence Interval (CI). Quality assessment of the included studies was assessed using the Consolidated Standards of Reporting Trials (CONSORT) 2010 statement. RESULTS Eleven studies met the predetermined inclusion criteria and were included in this meta-analysis. Amiodarone, dexmedetomidine, and magnesium significantly reduced the incidence of postoperative JET [Amiodarone: risk ratio 0.34; I2= 0%; Z=3.66 (P=0.0002); 95% CI 0.19-0.60. Dexmedetomidine: risk ratio 0.34; I2= 0%; Z=4.77 (P<0.00001); 95% CI 0.21-0.52. Magnesium: risk ratio 0.50; I2= 24%; Z=5.08 (P<0.00001); 95% CI 0.39-0.66]. CONCLUSION All three drugs have shown promising results in reducing the incidence of JET. Our systematic review found that dexmedetomidine is better in reducing the length of ICU stays as well as mortality. In addition, dexmedetomidine also has the least pronounced side effects among the three. However, it should be noted that this conclusion was derived from studies with small sample sizes. Therefore, dexmedetomidine may be considered as the drug of choice for preventing JET.

Abstract
INTRODUCTION The Coronavirus Disease 2019 (COVID-19) pandemic negatively impacted global healthcare. Consequences in Pediatric and Congenital Heart Surgery programmes and mortality of congenital heart patients infected with severe acute respiratory syndrome coronavirus-2 (SARS-Cov-2) is still to be determined. OBJECTIVE To study the COVID-19 pandemic implications in Brazilian Pediatric and Congenital Heart Surgery programmes. METHODS We conducted a national online survey covering all states that perform Pediatric and Congenital Heart Surgery from 10 November to 22 November, 2020, using a Google forms questionnaire. We formulated questions related to impact on surgical volume, case-mix, and mortality. Then we asked about short-term post-operative COVID-19 infection and outcomes. RESULTS We received responses from 46 centres representing all states where there were a Pediatric and Congenital Heart Surgery programme and all high-volume centres across the country. All but one centre experienced a significant decrease in surgical volume, and 23.9% of the responders revealed less than one-quarter of volume decrement. On the other hand, in over 70% of the centres, there was a significant surgical volume reduction. In addition to this, there was a shift in case-mix in 41 centres (89.1%) towards more complex cases. More than one-third of the responders revealed increased mortality in 2020 compared to previous years, and 43.5% of the programmes (20 centres) had at least one patient contaminated by SARS-Cov-2, accounting for 48 patients. Mortality in post-operative infected patients was 45.8% (22 patients). CONCLUSIONS In general, Brazilian Pediatric and Congenital Heart Surgery programmes were severely affected by decreased surgical volume, unbalanced case-mix towards more complex cases, and increased mortality. Almost half of the programmes related post-operative COVID-19 contamination with high mortality.
