RESUMEN
Anomalous aortic origin of the coronary artery(AAOCA) refers to the abnormal initiation, route, or distribution of coronary arteries, which is generally believed to be caused by abnormal or incomplete development of embryonic coronary arteries, and is a rare congenital cardiovascular malformation. It can exist independently without other congenital heart disease. With the development of medical science and people's understanding of AAOCA, more and more AAOCA has been detected, and its clinical significance has attracted more and more attention. Based on abnormal coronary artery opening, malignant or potential contorts can cause long-term blood flow dynamic change, appear abnormal blood vessel hardening of the arteries, at the same time due to walk in the pulmonary artery and the ascending aorta between two vessels, vulnerable to the extrusion of large blood vessels, which caused a temporary blood flow in coronary artery interruption, can cause acute angina pectoris, myocardial infarction, arrhythmia, exercise-induced cardiac syncope. This review focuses on the anatomy, diagnosis and treatment of coronary artery abnormalities arising from aorta.
RESUMEN
BACKGROUND: Our study aimed to compare the prevalence of postoperative fever during the COVID-19 pandemic period with that of the preceding non-pandemic period. METHODS: A retrospective analysis was conducted on patients with pectus excavatum (PE) undergoing minimally invasive repair (also called NUSS procedure) at Nanjing Children's Hospital from January 1, 2017 to March 1, 2019 (Group 2019), and from January 1, 2020 to March 1, 2021 (Group 2021). Data from a total of 284 patients, consisting of 200 (70.4%) males and 84 (29.6%) females with an average age of 9.73 ± 3.41 (range, 4 to 17) years, were collected. The presence of post-operative fever (defined as a forehead temperature of 37.5â or above within 72 h post-surgery), as well as the time of operation, duration of postoperative mechanical ventilator and urinary catheter use, and length of hospitalization were all assessed in admitted patients from Group 2019 (n = 144) and Group 2021 (n = 140). Postoperative white blood cell (WBC), C-reactive protein (CRP) levels, and prevalence of postoperative complications (i.e., pneumothorax, pulmonary atelectasis, pneumonia, wound infection, and dehiscence) were also determined. RESULT: Our results showed a statistically significant decrease in the incidence of postoperative fever within 24 to 72 h of surgery in patients admitted from Group 2019 as compared to Group 2021 (p < 0.001), as well as a decrease in peak body temperature within 72 h (p < 0.05). Meanwhile, no significant differences were observed in age and body mass index (BMI), time of operation, or duration of postoperative mechanical ventilator and urinary catheter use between the two groups (p > 0.05). The average hospitalization length of Group 2021 was significantly shorter than Group 2019 (12.49 ± 2.57 vs. 11.85 ± 2.19 days, p < 0.05). Furthermore, while the WBC count between the two groups 24 h after surgery showed a statistical difference (p < 0.05), no differences in CRP levels or the incidence of postoperative complications were observed (p > 0.05). CONCLUSION: The prevalence of postoperative fever within 72 h of surgery and the length of hospital stay for patients with PE undergoing NUSS surgery were both decreased in Group 2021. We propose that the above phenomenon may be related to increased used of personal protection equipment (such as surgical masks and filtering facepiece respirators (FFRs)) by physicians, nurses, and the patients themselves.

Purpose: Explore the transcription change of brain ischemia and reperfusion injury after deep hypothermic low flow. Method: The data from PRJNA739516 and GSE104036 were obtained for the differentially expressed genes identification, functional enrichment analysis, gene set enrichment analysis, protein-protein interaction construction and hub gene identification. Oxygen and glucose deprivation model was set to validate the hub gene and explore the detailed brain injury mechanism. Result: Interleukin, immunological response, NF-κB signaling pathway, G protein-coupled receptor signaling pathway and NLRP inflammatory are functional pathway were enriched in differentially expressed genes analysis. Sucnr1, Casr, Cxcr4, C5ar1, Tas2r41, Tas2r60 and Hcar2 were identified and verified in the OGD model. Knocking down GPR91 reduces the inflammatory response after OGD and GPR91 may be involved in the inflammatory pre-reaction through the synergistic activation of NF-κB, NLRP3, and IL-1ß respectively. Conclusion: Our study found that Interleukin, immunological response, NF-κB signaling pathway, G protein-coupled receptor signaling pathway and NLRP inflammatory are all associated with brain ischemia and reperfusion injury after deep hypothermic low flow and GPR91 can activate NF-κB/NLRP3 pathway and trigger the release of IL-1ß in this progress.
RESUMEN
BACKGROUND: Cardiopulmonary bypass may cause malfunction in the myocardium. Cuproptosis is a novel cell death aggregating mitochondrial proteins. However, the research on cardiopulmonary bypass-caused heart tissue injury in immune infiltration and cuproptosis is limited. METHOD: Immune infiltration, enrichment analysis, protein-protein interaction network, and medication prediction are applied to reanalysis differentially expressed genes and cuproptosis-related genes in gene expression omnibus data set GSE132176. RESULTS: Seven cuproptosis related genes (PDHA1, LIPT1, LIAS, DLST, DLD, DLAT, and DBT) and dendritic cells and Th1 cells are involved in heart tissue injury in response to surgery with cardiopulmonary bypass. CONCLUSIONS: Immune infiltration and cuproptosis are potential mechanisms by which cardiopulmonary bypass surgery may cause damage to heart tissue, which may be a new therapeutic target.

Objective:To evaluate the feasibility of measuring pulmonary venous blood flow spectrum by transesophageal ultrasound in assessing intraoperative left atrial pressure (LAP) in pediatric patients with complex congenital heart disease.Methods:Twenty-five pediatric patients with complex congenital heart disease of either sex, aged < 3 yr, of American Society of Anesthesiologists physical status Ⅲ or Ⅳ, with New York Heart Association class Ⅲ or Ⅳ, undergoing surgery with general anesthesia and requiring LAP monitoring during surgery, were selected.Transesophageal echocardiography was used to record the left pulmonary venous blood flow spectrum during surgery.S wave velocity (PV S), D wave velocity (PV D), AR wave velocity (PV AR), and deceleration time of pulmonary venous diastolic flow (DT D) were measured at 15 min after termination of CPB.The ratio of S wave peak velocity to D wave peak velocity (S/D ratio) was calculated.Measurement was carried out for 3 consecutive cardiac cycles, and the average value was calculated.The LAP was simultaneously measured through the left atrial piezometer.Pearson correlation analysis was performed between PV S, PV D, PV AR, DT D, S/D ratio and LAP. Results:PV S, PV D, PV AR and S/D ratio had no correlation with LAP ( r=-0.06, 0.21, 0.19, -0.38, respectively, P>0.05), while DT D was negatively correlated with LAP ( r=-0.84, P<0.05). Conclusions:DT D measured by transesophageal ultrasound can be used to evaluate intraoperative LAP in pediatric patients with complex congenital heart disease.
RESUMEN
BACKGROUND@#Little is known about the effects of environmental cobalt exposure on insulin resistance (IR) in the general adult population. We investigated the association between cobalt concentration and IR.@*METHODS@#A total of 1281 subjects aged more than 20 years with complete blood cobalt data were identified from the National Health and Nutrition Examination Survey (NHANES) 2015-2016 cycle. Blood cobalt levels were analyzed for their association with IR among all populations and subgroups by sex. Regression coefficients and 95% confidence intervals (CIs) of blood cobalt concentrations in association with fasting glucose, insulin and homeostatic model assessment of insulin resistance (HOMA-IR) were estimated using multivariate linear regression after adjusting for age, sex, ethnicity, alcohol consumption, body mass index, education level, and household income. A multivariate generalized linear regression analysis was further carried out to explore the association between cobalt exposure and IR.@*RESULTS@#A negative association between blood cobalt concentration (coefficient = - 0.125, 95% CI - 0.234, - 0.015; P = 0.026) and HOMA-IR in female adults in the age- and sex-adjusted model was observed. However, no associations with HOMA-IR, fasting glucose, or insulin were found in the overall population. In the generalized linear models, participants with the lowest cobalt levels had a 2.74% (95% CI 0.04%, 5.50%) increase in HOMA-IR (P for trend = 0.031) compared with subjects with the highest cobalt levels. Restricted cubic spline regression suggested that a non-linear relationship may exist between blood cobalt and HOMA-IR.@*CONCLUSIONS@#These results provide epidemiological evidence that low levels of blood cobalt are negatively associated with HOMA-IR in female adults.

The mean follow-up time was(19.49±17.48) months(1-68 months). Postoperative echocardiography showed that the left heart function and mitral regurgitation were significantly improved.Conclusion:Mitral valvuloplasty can significantly correct mitral insufficiency in children, and it has satisfactory mid-term efficacy and good clinical value.
RESUMEN
Objective:To investigate the common types, surgical treatment and effects of tracheal stenosis in children.Methods:A total of 23 children with tracheal stenosis in our hospital from December 2017 to August 2020 were retrospectively reviewed, including 14 males and 9 females. The mean age at operation was(8.9±5.8)months(range: 2-3 months) and the mean weight was(6.4±2.3)kg(range: 4.2-10.5 kg). The common types of tracheal stenosis were complete tracheal ring in 9 children, tracheomalacia in 10 and subglottic membranous annular hyperplasia in 4. The type of congenital heart diseases included 10 patients of pulmonary artery sling, 1 of tetralogy of Fallot, 5 of ventricular septal defect, 1 of pulmonary atresia, and 1 of right aortic arch with aberrant left subclavian artery. Slide tracheoplasty was performed in 9 patients, external splint in 8, endotracheal stent in 2 and tracheal dilation in 4. All children were followed up after 1, 3, 6, and 12 months of operation with CT and bronchoscopy.Results:There was 1 death in all 23 patients and the mortality was 4.3%, which died of granulation tissue hyperplasia after slide tracheoplasty. Reoperation was performed in 1 patient with endotracheal stent. All patients were followed for 1 to 24 months. Clinical symptoms of tracheal stenosis disappeared and the results of CT and bronchoscopy were satisfied.Conclusion:Slide tracheoplasty is the effective surgical method for complete trachea ring. 3D printing bioresorbable external splint is a promising method for the treatment of tracheomalacia.

<p><b>OBJECTIVE</b>To compare the efficacy of thoracoscopic surgery versus thoracotomy in repairing esophageal atresia type Ⅲ with tracheoesophageal fistula (EA/TEF) in neonates.</p><p><b>METHODS</b>A retrospective analysis was conducted in 97 neonates who underwent EA/TEF repair between January 2012 and December 2017 in the Affiliated Children's Hospital of Nanjing Medical University, including 75 patients receiving thoracotomy and 22 patients receiving thoracoscopic surgery. The perioperative data and the incidence of early postoperative complications were compared between two groups.</p><p><b>RESULTS</b>The operations were completed in all patients. One child (4.5%) in thoracoscopic surgery group was converted to thoracotomy with modified Livaditis procedure due to the long distance of two blind ends (>4 cm) and thinner distal end. The operation time was longer in thoracoscopic surgery group[(143±48) min vs. (120±40) min, <0.05], but the postoperative ventilation time was shorter[(55±22) h vs. (65±19) h, <0.05] and the first oral feeding was earlier in thoracoscopic surgery group[(3.2±1.1) d vs (3.9±1.3) d, <0.05]. No statistical difference was observed in the ratio of red blood cell transfusion, length of hospital stay and drainage tube indwelling time between two groups (all >0.05). The incidence of lung complications in thoracotomy group was higher than that in thoracoscopic surgery group (20.0% vs. 9.1%, <0.01), while there were no significant differences in the incidence of other postoperative complications between two groups. There was no death in thoracoscopic surgery group, while 2 patients died in thoracotomy group.</p><p><b>CONCLUSIONS</b>Thoracoscopic repair is a preferred surgical procedure for EA/TEF in neonates.</p>
RESUMEN
Congenital esophageal atresia is one of the serious birth defects. Identifying the etiology and mechanism of esophageal development can provide clues for the effective prevention and treatment of congenital esophageal atresia. Recent studies have shown that a variety of transcription factors and signaling pathways (including Wnt signaling pathway, bone morphogenetic protein signaling pathway, SHH signaling pathway, vascular endothelial growth factor signaling pathway) are involved in esophageal proliferation, differentiation and other processes, promoting the normal development of esophagus. Understanding the regulatory mechanisms during the normal development of esophagus can give reference for the prevention and treatment of congenital esophageal atresia. This article reviews the research progress on related transcription factors and signaling pathways in esophageal development.
RESUMEN
Mitral valve prolapse is a disease which causes mitral regurgitation,which is one of the common causes of mitral insufficiency.With the aggravation of blood reflux,mitral valve prolapse will eventually lead to pulmo-nary hypertension,heart failure and even death in children.The main diagnostic methods include chest X-ray,echocar-diography,spiral CT and magnetic resonance imaging.Mitral valvuloplasty is the main surgical method for mitral valve prolapse in children.It includes valvuloplasty,annuloplasty,tendon chordoplasty,edge-to-edge mitral valve repair, and so on.Now,the progress in surgical diagnosis and treatment of mitral valve prolapse in children were reviewed in or-der to provide a meaningful reference for its individual treatment.
RESUMEN
The parachute mitral valve is a rare group of heart valve diseases that are typically characterized by only one papillary muscle.All the chordae tendineaes are connected to the papillary muscle and shaped like a para-chute.It mainly causes mitral stenosis and occasionally leads to mitral regurgitation. Due to the early appearance of clinical symptoms and rapid development of the disease,early accurate diagnosis and surgical treatment are needed. Common surgical treatments are mitral valve repair and mitral valve replacement.Now,the progress of surgical treatment of "parachute-like" mitral valve malformation was reviewed in order to provide a meaningful reference for its surgical treatment.

RESUMEN
Objective To investigate the effect and feasibility of early enteral nutrition support on postoperative nutrition assessments and clinical outcomes in children patients with congenital heart disease. Methods From October 2013 to October 2014, a number of 100 cases congenital heart disease aged six months to two years old were treated with early enteral nutrition support after operation. According to gender, fifty patients were randomly divided into the intervened group, who were treated with the early enteral nutrition support program. The other fifty patients were divided into control group with no nutrition sup-port. The detailed early enteral nutrition support project were( a) withdraw breathing machine at the same day, giving enteral nutrition 6 hours later after postoperation;( b) patients assist with long-term breathing machine, giving enteral nutrition 12-24 hours later after postoperation. The age, heigth, weight, serum C- reactive protein(CRP), serum retinoic binding protein ( RBP) , serum prealbumin( Pre-ALB) were recorded before operation. Seven days after operation, above indicators were ob-served again. In addition, the first time of excrete, the number of feeding interruption, the time of feeding, the time of ventila-tor, and the related complications were also recorded at hospitalization period. Results No difference of basic information and accompanying complications were observed between control and nutritional intervention group. As to nutritional status, weight-for-age z-score(WAZ) were significant higher in the nutritional intervention group than the control group( -0. 22 ± 1. 16 vs. 0.73 ±1.29, P=0.019) after operation. However length/height-for-age z-score(LAZ/HAZ) and weight-for-length/height z-score( WLZ/WHZ) were similar between control and nutritional intervention group whatever pre-operation and postoperation. Preoperative CRP, RBP, and Pre-ALB were no significant difference between early enteral nutrition and control group. After operation CRP levels in the early enteral nutrition group were significantly lower than that of control group[(45.2 ±16.2)mg/L vs.(67.3±35.5)mg/L,P<0.001],whileRBP[(0.3±0.1)mg/Lvs.(0.2±0.1)mg/L]andPre-ALB[(35.2±12.2)g/Lvs.(25.2±14.2)g/L] weresignificantlyhigherthanthoseofcontrolgroup(Pvaluewere0.031and0.029,respective-ly) . In the early nutritional intervention group and control group, the first time of excrete were remarkable in advance in nutri-tionalinterventiongroupcompredtocontrolgroup[(36±12)hvs.(65±15)h,P=0.008],whilethedifferenceoffeeding interruption times, intensive care unit( ICU) time and mechanical ventilation time in the two groups were not statistically signif-icant(P>0. 05). Conclusion Early nutritional intervention can help gastrointestinal function, enhance nutritional status, lower serum CRP levels and increased serum RBP and Pre-ALB concentrations. It did not add ICU time and ventilation time.
