Abstract
BACKGROUND The optimal timing of surgical repair for infants with complete atrioventricular canal defect remains controversial, as there are risks to both early and late repair. We address this debate by investigating the association of various risk factors, including age and weight at surgery, markers of failure to thrive, and pulmonary vascular disease, with postoperative length of stay following complete atrioventricular canal repair. METHODS Infants who underwent repair of complete atrioventricular canal were identified from our institutional Society of Thoracic Surgeons Congenital Heart Surgery Database. Additional clinical data were collected from the electronic medical record. Descriptive statistics were computed. Associations between postoperative length of stay and covariates of interest were evaluated using linear regression with bootstrap aggregation. RESULTS From 2001 to 2020, 150 infants underwent isolated complete atrioventricular canal repair at our institution. Pre-operative failure to thrive and evidence of pulmonary disease were common. Surgical mortality was 2%. In univariable analysis, neither weight nor age at surgery were associated with mortality, postoperative length of stay, duration of mechanical ventilation, or post-operative severe valvular regurgitation. In multivariable analysis of demographic and preoperative clinical factors using bootstrap aggregation, increased postoperative length of stay was only significantly associated with previous pulmonary artery banding (33.9 day increase, p = 0.03) and preoperative use of supplemental oxygen (19.9 day increase, p = 0.03). CONCLUSIONS Our analysis shows that previous pulmonary artery banding and preoperative use of supplemental oxygen were associated with increased postoperative length of stay after complete atrioventricular canal repair, whereas age and weight were not. These findings suggest operation prior to the onset of pulmonary involvement may be more important than reaching age or weight thresholds.

Abstract
The Congenital Heart Surgeons' Society (CHSS) was founded by 16 congenital heart surgeons in 1973, who endeavored to share their clinical advances in an informal setting that would stimulate honest and forthright discussions. As the Society grew, prospective studies were organized from a centralized data center that was established and based first in Birmingham, Alabama, thence to Toronto, and recently in a collaboration between Toronto and the Cleveland Clinic. These studies formed the basis for a myriad of outcomes reports that favorably impacted surgical results. The Kirklin-Ashburn Fellowship was created and endowed by the membership which has been successful in training many congenital heart surgeons. The CHSS was then incorporated into a 501(c) (3) not-for-profit organization with bylaws, officers, and committees in 2002. Increased membership followed. The CHSS has become the face of congenital heart surgery in North America by affiliating with the World Journal for Pediatric and Congenital Heart Surgery, having one designated member on the American Board of Thoracic Surgery, and hosting joint meetings with the European Congenital Heart Surgeons Association. Since 2002, 11 presidents have been elected for two-year terms and have guided the advances that have been achieved by the CHSS. Their contributions and achievements are highlighted in chronological order.

Abstract
BACKGROUND This study aimed to evaluate the efficacy and safety of high-frequency oscillation ventilation combined with intermittent mandatory ventilation in infants with acute respiratory distress syndrome after congenital heart surgery. METHODS We retrospectively analysed the clinical data of 32 infants who were ventilated due to acute respiratory distress syndrome after congenital heart surgery between January, 2020 and January, 2022. We adopted high-frequency oscillation ventilation combined with intermittent mandatory ventilation as the rescue ventilation mode for infants who were failing conventional mechanical ventilation. RESULTS After rescue high-frequency oscillation ventilation combined with intermittent mandatory ventilation, the dynamic compliance (Cdyn), PaO2 and PaO2/FiO2 ratio of the infants improved compared with conventional mechanical ventilation (p < 0.05). Moreover, high-frequency oscillation ventilation combined with intermittent mandatory ventilation resulted in a significant decrease in arterial-alveolar oxygen difference (AaDO2), FiO2, and oxygenation index (p < 0.05). No significant effect on haemodynamic parameters was observed. Moreover, no serious complications occurred in the two groups. CONCLUSION Rescue high-frequency oscillation ventilation combined with intermittent mandatory ventilation significantly improved oxygenation in infants who failed conventional mechanical ventilation for acute respiratory distress syndrome after congenital heart surgery. Thus, this strategy is considered safe and feasible. However, further studies must be conducted to confirm the efficacy and safety of high-frequency oscillation ventilation combined with intermittent mandatory ventilation as a rescue perioperative respiratory support strategy for CHD.

Abstract
BACKGROUND Surgical repair of tetralogy of Fallot (ToF) depends on the anatomical variations of the heart defect. A group of patients with a hypoplastic pulmonary valve annulus required a transannular patch. This study aimed to evaluate the early and late outcomes of ToF repair with a transannular Contegra® monocuspid patch in a single center. METHODS A retrospective review of medical records was conducted. This study included 224 children with a median age of 13 months who underwent ToF repair with a Contegra® transannular patch in over 20 years of observation. The primary outcomes were hospital mortality and need for early reoperations. The secondary outcomes were late death and event-free survival. RESULTS The hospital mortality in our group was 3.1%, whereas two patients required early reoperation. Three patients were excluded from the study because follow-up data were not available. In the remaining group of patients (212 patients), the median follow-up was 116 (range, 1-206) months. One patient died because of sudden cardiac arrest at home six months after surgery. Event-free survival was observed in 181 patients (85.4%), whereas the remaining 30 patients (14.1%) required graft replacement. The median time to reoperation was 99 (range, 4-183) months. CONCLUSIONS Although surgical treatment of ToF has been performed for more than 60 years worldwide, the optimal approach in children with a hypoplastic pulmonary valve annulus remains debatable. Among options, the Contegra® monocuspid patch can be effectively used in transannular repair of ToF with good long-term results.

Infants less than or equal to 2.5 kg have increased mortality and worse motor neurodevelopmental outcomes at 2 years of age after Norwood-Sano palliation. JTCVS OPEN 2023; 14:417-425. [PMID: 37425435 PMCID: PMC10328833 DOI: 10.1016/j.xjon.2023.03.007] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 11/02/2022] [Revised: 02/11/2023] [Accepted: 03/07/2023] [Indexed: 07/11/2023]
Abstract
Objectives In infants with single-ventricle congenital heart disease, prematurity and low weight at the time of the Norwood operation are risk factors for mortality. Reports assessing outcomes (including neurodevelopment) post Norwood palliation in infants ≤2.5 kg are limited. Methods All infants who underwent a Norwood-Sano procedure between 2004 and 2019 were identified. Infants ≤2.5 kg at the time of the operation (cases) were matched 3:1 with infants >3.0 kg (comparisons) for year of surgery and cardiac diagnosis. Demographic and perioperative characteristics, survival, and functional and neurodevelopmental outcomes were compared. Results Twenty-seven cases (mean ± standard deviation: weight 2.2 ± 0.3 kg and age 15.6 ± 14.1 days at surgery) and 81 comparisons (3.5 ± 0.4 kg and age 10.9 ± 7.9 days at surgery) were identified. Post-Norwood, cases had a longer time to lactate ≤2 mmol/L (33.1 ± 27.5 vs 17.9 ± 12.2 hours, P < .001), longer duration of ventilation (30.5 ± 24.5 vs 18.6 ± 17.5 days, P = .005), greater need for dialysis (48.1% vs 19.8%, P = .007), and greater need for extracorporeal membrane oxygenation support (29.6% vs 12.3%, P = .004). Cases had significantly greater postoperative (in-hospital) (25.9% vs 1.2%, P < .001) and 2-year (59.2% vs 11.1%, P < .001) mortality. Neurodevelopmental assessment showed the following for cases versus comparisons, respectively: cognitive delay (18.2% vs 7.9%, P = .272), language delay (18.2% vs 11.1%, P = .505), and motor delay (27.3% vs 14.3%, P = .013). Conclusions Infants ≤2.5 kg at Norwood-Sano palliation have significantly increased postoperative morbidity and mortality up to 2-year follow-up. Neurodevelopmental motor outcomes were worse in these infants. Additional studies are warranted to assess the outcome of alternative medical and interventional treatment plans in this patient population.

Abstract
Background Aortic valve-sparing procedures have been established as a mainstream treatment option for adult patients with aortic root aneurysms. However, data regarding their use in the pediatric population is limited. This study reports on our experience with aortic valve-sparing procedures in children. Methods A retrospective review was conducted of all patients who underwent an aortic valve-sparing procedure at the Royal Children's Hospital, Melbourne, Australia between April 2006 and April 2016. Clinical and echocardiographic data were analyzed. Results The study included 17 patients, with a median age of 15.7 years and a majority of patients being male (82.4%). The most common diagnosis was transposition of great arteries after arterial switch operation, followed by Loeys-Dietz syndrome and Marfan syndrome. Preoperative echocardiography showed more than moderate aortic regurgitation in 94.1% of the patients. The David procedure was performed in all 17 patients, with no mortality during follow-up. Reoperation was required in 29.4% of patients, and 23.5% required aortic valve replacement. Freedom from reoperation for aortic valve replacement at 1, 5, and 10 years was 93.8%, 93.8% and 68.2% respectively. Conclusions Aortic valve-sparing surgery can be successfully performed in the pediatric population. However, it requires a highly skilled surgeon due to the often dysplastic or distorted nature of these valves and the need for additional procedures on the aortic valve leaflets.

Abstract
Multiple tissue perfusion markers are described to guide therapy in critically ill pediatric patients undergoing congenital heart surgery. Given the advantages of capillary refill time, our goal is to determine its predictive capacity for mortality and postoperative extracorporeal oxygenation requirements in congenital heart surgery and compare it to serum lactate. We conducted a prospective cohort observational study in a single high-complexity university hospital. Serum lactate and capillary refill time were measured at five predetermined time points: preoperative, immediate postoperative, 6, 12, and 24 h after the surgery. Prolonged immediate postoperative, 6 h, and 12 h capillary refill time measurements turned out to be independent risk factors for both outcomes. The capillary refill time area under the curve ranged between 0.70 and 0.80, while the serum lactate resulted between 0.79 and 0.92 for both outcomes. Both tissue perfusion markers resulted in mortality and extracorporeal oxygenation requirement predictors. Given the advantages of capillary refill time over serum lactate, a monitoring strategy including these two perfusion markers should be considered for congenital heart surgeries.

Progressive changes in residual gradient after aortic coarctation repair and its role in the prediction of reintervention: A longitudinal data analysis. Ann Pediatr Cardiol 2023; 16:182-188.

Abstract
Background Repair of aortic coarctation through left thoracotomy is the standard treatment when anatomically feasible. Long-term outcomes are well studied, including the need for reintervention. However, the timely variation in residual gradients across the repaired segment is ill-defined. The aim of this work was to study the progressive changes of estimated peak gradient (ePG) acquired by transthoracic continuous-wave Doppler echocardiography across the aortic arch after repair and to assess the role of timing of assessment and values of ePG in prediction of reintervention. Materials and Methods All eligible patients for this study who underwent aortic coarctation repair through left thoracotomy from 2001 to 2017 were reviewed. Details of the aortic arch dimensions and associated lesions were obtained by transthoracic echocardiography (TTE). The primary outcome was the ePG across the aortic arch after repair. Longitudinal data analyses with mixed effect modeling were used to determine independent predictors for ePGs. Results A total of 312 patients were included. Median age and weight were 30 days and 4 kg, respectively. Associated lesions included ventricular septal defect (VSD) (53%), bicuspid aortic valve (53%) and mitral stenosis (25%). Over 15-years follow-up the freedom from reintervention was 92.3%, while 24 out of the 312 patients underwent reintervention (7.7%). Longitudinal data analyses of serial 2566 TTE studies were done. The graphical display showed that the ePG across coarctation area in the first postoperative TTE was the most notable difference between those who underwent reintervention and those who did not. Further testing with proportional hazard and logistic regression modeling confirmed this finding. The area under receiver operating curve statistics showed that an ePG of 25 mmHg is an optimal cutoff value for the prediction of the reintervention. Conclusions The ePG acquired in the first postoperative TTE is the most important predictor for reinterventions. The presence of VSD is associated with decreased ePGs. We propose that an ePG in the first postoperative TTE of 25 mmHg or more is a strong predictor for the need of reintervention.

Abstract
BACKGROUND Peripheral pulmonary artery stenosis (PPAS) is a relatively rare form of congenital heart disease often associated with Williams syndrome, Alagille syndrome, and elastin arteriopathy. This disease is characterized by stenoses at nearly all lobar and segmental ostia and results in systemic-level right ventricular pressures. The current study summarizes our experience with the surgical treatment of PPAS. METHODS This was a retrospective review of 145 patients who underwent surgical repair of PPAS. This included 43 patients with Williams syndrome, 39 with Alagille syndrome, and 21 with elastin arteriopathy. Other diagnoses include tetralogy of Fallot with PPAS (n = 21), truncus arteriosus (n = 5), transposition (n = 3), double-outlet right ventricle (n = 2), arterial tortuosity syndrome (n = 3), and other (n = 8). RESULTS The median preoperative right ventricle to aortic peak systolic pressure ratio was 1.01 (range, 0.50-1.60) which was reduced to 0.30 (range, 0.17-0.60) postoperatively. The median number of ostial repairs was 17 (range, 6-34) and median duration of cardiopulmonary bypass was 398 minutes (range, 92-844). There were 3 in-hospital deaths (2.1%). The median duration of follow-up was 26 months (range, 1-220) with 4 late deaths (2.9%). Eighty-two patients have subsequently undergone catheterization and 74 had a pressure ratio <0.50. CONCLUSIONS The surgical treatment of PPAS resulted in a 70% reduction in right ventricular pressures. At 3 years, freedom from death was 94% and 90% of those evaluated maintained low pressures. These results suggest that the surgical treatment of PPAS is highly effective in most patients.

Abstract
Initial management of patients with tetralogy of Fallot, unfavorable anatomy, and reduced pulmonary blood flow is controversial and continues to be a clinical challenge. Pulmonary to systemic shunt anastomosis or primary correction in neonates and small infants is associated with higher morbimortality and increased number of reoperations. Initial right ventricle outflow tract stenting palliation has emerged as an attractive alternative. We report our experience in 14 patients operated on with tetralogy of Fallot and previous right ventricle outflow tract stenting from March 2018 to June 2022. All stented patients had pulmonary annulus and main pulmonary artery Z score ≤ -2.5. Surgical outcomes, complications, and mortality at 30 days were evaluated. Patient's age and weight at surgery were 5.9 months (2-17) and 6.1 kg (3.9-8.9), respectively. Stents were completely removed in 57.1% of patients. A transannular patch was placed in 10 patients, 3 patients required a right ventricle to pulmonary artery conduit due to coronary anomalies and in 1 patient, the pulmonary valve was preserved. Length of stay and ventilation time were 13.6 days (5-27) and 44.8 h (6-44), respectively. Mean time for right ventricle outflow tract stent implantation to surgical correction was 4 months (2-16). There was no mortality, and mean follow-up time of this cohort was 23.1 month (1-41). Surgical correction of severe tetralogy of Fallot after right ventricle outflow tract stenting is an effective alternative achievable without an increase in morbidity and mortality. Difficulty in stent extraction is related to the time since implantation. More number of patients and longer follow-up time are needed to confirm these initial results.

Abstract
The congenital heart surgeon frequently encounters patients with various genetic disorders requiring surgical intervention. Although the specifics of the genetics for these patients and their families lie in the purview of specialists in genetics, the surgeon is well-served to be familiar with aspects of specific syndromes that impact surgical management and perioperative care. This aids in counseling families in expectations for the hospital course and recovery as well as can impact intraoperative and surgical management. This review article summarizes key characteristics for the congenital heart surgeon to be familiar with for common genetic disorders as they help coordinate care.

Abstract
OBJECTIVES Approximately 0.2% to 2.7% of children with congenital heart disease require a tracheostomy after cardiac surgery with the majority having single ventricle (SV) type heart lesions. Tracheostomy in SV patients is reported to be associated with high mortality. We hypothesized that short- and long-term survival of patients with SV heart disease would vary according to tracheostomy indication. METHODS This is a single center, 20-year, retrospective review of all patients with SV heart disease who underwent tracheostomy. Demographic, cardiac anatomy, surgical, intensive care unit, and hospital course data were collected. The primary outcome was survival following tracheostomy. Secondary outcome was the completion of staged palliation to Fontan. RESULTS In total, 25 patients with SV heart disease who underwent tracheostomy were included. Indications for tracheostomy included one or more of the following: tracheobronchomalacia (n = 8), vocal cord paralysis (n = 7), tracheal/subglottic stenosis (n = 6), primary respiratory insufficiency (n = 4), diaphragm paralysis (n = 3), suboptimal hemodynamics (n = 2), and other upper airway issues (n = 1). Survival at six months, one year, five years, and ten years was 76%, 68%, 63%, and 49%, respectively. Most patients completed Fontan palliation (64%). Patients who underwent tracheostomy for suboptimal hemodynamics and/or respiratory insufficiency had a higher mortality risk compared to those with indications of upper airway obstruction or diaphragm paralysis (hazard ratio 4.1, 95% confidence interval 1.2-13.7; P = .02). CONCLUSIONS Mortality risk varies according to tracheostomy indication in patients with SV heart disease. Tracheostomy may allow staged surgical palliation to proceed with acceptable risk if it was indicated for anatomic or functional airway dysfunction.

Abstract
BACKGROUND Either deep hypothermia with circulatory arrest or hypothermic perfusion with antegrade selective cerebral perfusion is used during the Norwood procedure for hypoplastic left heart syndrome. Normothermic perfusion has been described for pediatric patients. The aim of this study was to compare the early outcomes of patients undergoing the Norwood procedure with antegrade selective cerebral perfusion under hypothermia with the procedure under normothermia. METHODS From 2005 to 2020, 117 consecutive patients with hypoplastic left heart syndrome underwent the Norwood procedure: 68 (58.2%) under hypothermia and 49 (41.8%) under normothermia. Antegrade selective cerebral perfusion flow was adjusted to maintain right radial arterial pressure above 50 mm Hg, and a flow rate of 40 to 50 mL kg-1 min-1. Baseline characteristics, operative data, and postoperative outcomes including lactate recovery time were compared. RESULTS The baseline characteristics and cardiovascular diagnosis were similar in both groups. The normothermic group had a significantly shorter bypass time (in minutes) of 90.31 (±31.60) versus 123.63 (±25.33), a cross-clamp time of 45.24 (±16.35) versus 81.93 (±16.34), and an antegrade selective cerebral perfusion time of 25.61 (±13.84) versus 47.30 (±14.35) (P < .001). There were no statistically significant differences in the immediate postoperative course, or in terms of in-hospital mortality, which totaled 9 (18.4%) in the normothermic group, and 10 (14.9%) in the hypothermic group (P = .81). CONCLUSION The normothermic Norwood procedure with selective cerebral perfusion is feasible and safe in terms of in-hospital mortality and short-term outcomes. It is comparable to the standard hypothermic Norwood with selective cerebral perfusion.

Optimizing Referral Timing of Patients With Fontan Circulatory Failure for Heart Transplant. Transplant Proc 2023; 55:417-425. [PMID: 36868954 PMCID: PMC10133013 DOI: 10.1016/j.transproceed.2023.02.014] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/18/2022] [Revised: 12/11/2022] [Accepted: 02/03/2023] [Indexed: 03/05/2023]
Abstract
BACKGROUND There are no criteria guiding the timing of heart transplant referral for Fontan patients, nor are there any characteristics of those deferred or declined listing reported. This study examines comprehensive transplant evaluations for Fontan patients of all ages, listing decisions, and outcomes to inform referral practices. METHODS Retrospective review of 63 Fontan patients formally assessed by the advanced heart failure service and presented at Mayo Clinic transplant selection committee meetings (TSM) January 2006 to April 2021. The study is compliant with the Helsinki Congress and Declaration of Istanbul and included no prisoners. Statistical analysis was performed with Wilcoxon Rank Sum and Fisher's Exact tests. RESULTS Median age at TSM was 26 years (17.5, 36.5). Most were approved (38/63 [60%]); 9 of 63 (14%) were deferred and 16 of 63 (25%) were declined. Approved patients more commonly were <18 years old at TSM (15/38 [40%] vs 1/25 [4%], P = .002) compared with those deferred/declined. Complications of Fontan circulatory failure were less common in approved vs deferred/declined patients: ascites (15/38 [40%] vs 17/25 [68%], P = .039), cirrhosis (16/38 [42%] vs 19/25 [76%], P = .01), and renal insufficiency (6/38 [16%] vs 11/25 [44%], P = .02). Ejection fraction and atrioventricular valve regurgitation did not differ between groups. Pulmonary artery wedge pressure was overall high normal (12 mm Hg [9,16]) but higher in deferred/declined vs approved patients, 14.5 (11, 19) vs 10 (8, 13.5) mm Hg, P = .015. Overall survival was significantly lower in deferred/declined patients (P = .0018). CONCLUSION Fontan patient referral for heart transplant at younger age and before the onset of end-organ complications is associated with increased approval for transplant listing.

Abstract
BACKGROUND AND OBJECTIVE Key medical and surgical advances have been made in the longitudinal management of patients with "functionally" single ventricle physiology, with the principles of Fontan circulation applied to other complex congenital heart defects. The purpose of this article is to review all of the innovations, starting from fetal life, that led to a change of strategy for single ventricle. METHODS Our literature review included all full articles published in English language on the Cochrane, MedLine, and Embase with references to "single ventricle" and "univentricular hearts", including the initial history of the treatments for this congenital heart defects as well as the innovations reported within the last decades. KEY CONTENT AND FINDINGS All innovations introduced have been analyzed, including: (I) fetal diagnosis and interventions, in particular to prevent or reduce brain damages; (II) neonatal care; (III) post-natal diagnosis; (IV) interventional cardiology procedures; (V) surgical procedures, including neonatal palliations, hybrid procedures, bidirectional Glenn and variations, Fontan completion, biventricular repair; (VI) peri-operative management; (VII) Fontan failure, with Fontan take-down and conversion, and mechanical circulatory support; (VIII) transplantation, including heart, heart and lung, heart and liver; (IX) exercise; (X) pregnancy; (XI) adolescents and adults without Fontan completion; (XII) future studies, including experimental studies on animals, computational studies, genetics, stem cells and bioengineering. CONCLUSIONS These last 40 years have certainly changed the course of natural history for children born with any form of "functionally" single ventricle, thanks to the improvement in diagnostic and treatment techniques, and particularly to the increased knowledge of the morphology and function of these complex hearts, from fetal to adult life. There is still much left unexplored and room for improvement, and all efforts should be concentrated in collaborations among different institutions and specialties, focused on the same matter.

Abstract
Technical skill development in congenital heart surgery (CHS) is challenging due to numerous factors which potentially limit the hands-on operative exposure in surgical training. These challenges have stimulated the growth of simulation-based training through the development of 3D-printed models, providing hands-on surgical training (HOST). From its inception in 2015, the models used in the HOST program have constantly improved, and now include valvar/subvalvar apparatus and better materials that mimic real tissue. Evidence shows that deliberate, regular simulation practice can improve a surgeon's technical skills across the spectrum of CHS. Furthermore, surgical trainees who undergo simulation training are able to translate this improved performance into the operative environment with improved patient outcomes. Despite evidence to support the incorporation of simulation methods into congenital training, its widespread adoption into training curricula remains low. This is due to numerous factors including funding, lack of dedicated time or proctorship and access to models-all of which can be overcome with the newer generation of models and committed trainers. Training programs should consider incorporating simulation-methods as a routine component of congenital training programs.

Abstract
Background: High thoracic epidural analgesia (HTEA) plays a pivotal role in reducing stress and neuroendocrine response in cardiac surgeries. Aim: The primary objective is to assess the effect of HTEA, in pediatric cardiac surgery, on inflammatory markers (interleukin [IL]-6, IL-8, and tumor necrosis factor-α). The secondary objectives are to assess its effect on various organ systems, that is, pulmonary (PaO2, P/F ratio), renal (Creatinine clearance, somatic near infrared spectroscopy [NIRS], serum neutrophil gelatinase-associated lipocalin values), cardiac (cardiac index, serum Trop-I, and lactate levels), mechanical ventilation duration, and length of stay in hospital (LOS). Methods: The study included 188 pediatric patients, who underwent, on-pump cardiac surgery randomized into the Epidural Group (n = 92) and Non-Epidural Group (n = 96). After general anesthesia, a 23 G epidural catheter was placed at the T4-5 level with a Bupivacaine infusion while the Non-epidural Group received fentanyl infusion. Blood samples were collected at four-time points, T0(preop), T1(4 h), and on the first and second postoperative days (T2 and T3). Results: The inflammatory markers were reduced, while the outcomes variables of mechanical ventilation (MV) duration had lower values in the epidural group (19.5 h vs 47.3 h, P = .002). LOS was shorter (10.1 days vs 13.3 days, P = .016). pO2, PF ratio, and renal NIRS values were better in the Epidural Gp, while other parameters were comparable. Non-epidural Gp had more complications esp. Acute kidney injury requires RRT. Conclusion: HTEA use in pediatric, on-pump cardiac surgery offers a favorable profile in terms of reduction in the inflammatory markers and positive effect on the organ systems with lesser MV duration and the LOS.

Abstract
Background: Breast milk is known to prevent infections and is recommended for enteral feeding of infants after congenital heart surgery (CHS). During the Covid-19 pandemic, expressed breast milk (EBM) was not always available; hence, feeding after CHS was maintained with EBM or infant formula (IF) or both; we evaluated the impact of enteral feed type on early postoperative outcomes after CHS. Methods: In a prospective observational study, consecutive neonates and infants <4 months undergoing CHS were divided into EBM, IF, or EBM+IF groups; incidences of postoperative infections, ventilation duration, intensive care unit (ICU) stay, and mortality were studied. Results: Among 270 patients; 90 (33.3%) received EBM, 89 (32.9%) received IF, and 91 (33.7%) received EBM+IF. IF group had more neonates (78.7%[IF] vs 42.2%[EBM] and 52.7%[EBM+IF], P < 0.001) and greater surgical complexity. Postoperative infections were 9 (10.0%) in EBM; 23 (25.8%) in IF; and 14 (15.4%) in EBM+IF (P = .016). IF group (OR 2.58 [1.05-6.38], P = .040), absence of preoperative feeding (OR 6.97 [1.06-45.97], P = .040), and increase in cardiopulmonary bypass time (OR 1.005 [1.001-1.010], P = .027) were associated with postoperative infection. Ventilation duration in hours was 26 (18-47.5) in EBM; 47 (28-54.5) in IF; and 40 (17.5-67) in EBM+IF (P = .004). ICU stay in days was 4 (3-7) in EBM; 6 (5-9) in IF; and 5 (3-9) in EBM+IF (P = .001). Mortality did not differ (P = .556). Conclusion: IF group had a greater proportion of neonates with higher surgical complexity. Patients who received EBM after CHS had fewer postoperative infections and better postoperative outcomes compared to those receiving IF or EBM+IF.

Abstract
Anomalous left coronary artery from the pulmonary artery (ALCAPA) is a congenital malformation that classically presents within the first year of life. Few patients survive into adulthood, and initial presentation after the fourth decade of life is rare. We describe a 55-year-old woman who presented after cardiac arrest. She initially refused surgery and underwent automated implantable cardioverter defibrillator placement, followed later by surgical repair involving reimplantation of the left coronary artery to the aorta and pulmonary artery reconstruction using interposition grafts. We report this late presentation of ALCAPA and successful surgical management.

Abstract
Over 90% of the world's children with congenital heart disease do not have access to cardiac care. Although many models provide pediatric cardiac surgery in low- and middle-income countries, sustainability poses a barrier. We explore one model providing care for the underserved in Chennai, India, that came into existence through trial and error over 30 years across three phases. Phase 1 was a Tamilnadu state government-sponsored program that soon became unsustainable with unmet demands. Phase 2 utilized a grassroots foundation of a public-private partnership (PPP) with few donors and a hospital with suboptimal infrastructure. Phase 3 is the ongoing fine-tuning of the PPP model, with upgraded infrastructure and a well-trained team. Through indigenization, an average cardiac surgery costs Rupees (Rs.) 1,80,000 ($2400). The government funds Rs. 60,000 to 80,000 ($800-$1066.67), and the rest is funded through the fund pool. The goal is to perform 100 free surgeries annually by maintaining a fund pool of Rs. 50 lakhs ($66,666.67), which supplements government funds. This ensures equitable distribution of funds with no compromise on resources (disposables, single-use cannulas, etc). Our model ensures the dignity of the patient, fair compensation for workers, and is practical, affordable, and easily adaptable. Thus far, this model provided free cardiac surgery for 357 children from Risk Adjusted Congenital Heart Surgery Score of 1 to 4, with an overall mortality of 2.73%. The prerequisites for this model are having a "spark plug," a dedicated surgical team, a partnership with state-of-the-art infrastructure, and a steady flow of funds.
