Objective: To explore the risk factors of malnutrition in infants with congenital heart disease within one year after surgery. Methods: This retrospective cohort study selected 502 infants with congenital heart disease who underwent surgical treatment in Guangzhou Women and Children's Medical Center from February 2018 to January 2019. Their basic information and clinical data were analyzed, and their nutrition status after the surgery was followed up by questionnaire survey. Weight-for-age Z score (WAZ)≤-2 one year after operation was defined as malnutrition group, and WAZ>-2 was non-malnutrition group. The perioperative indicators and complementary food advancement were compared between the two groups by chi-square test, t-test, and Kruskal-Wallis test. The risk factors of malnutrition were analyzed by Logistic regression. Results: A total of 502 infants were selected, including 301 males and 201 females, with the age of 4.1 (2.0, 6.8) months. There were 90 cases in malnutrition group and 412 cases in non-malnutrition group. The body length and weight at birth in the malnutrition group were lower than those in the non-malnutrition group ((47.8±3.8) vs. (49.3±2.5) cm, (2.7±0.6) vs.(3.0±0.5) kg, both P<0.001). The proportion of paternal high school education or above and the proportion of family per capita income of 5 000 yuan or above in the malnutrition group were lower than those in the non-malnutrition group ((18.9% (17/90) vs. 30.8% (127/412), 18.9% (17/90) vs. 33.7% (139/412), both P<0.05). Compared to the non-malnutrition group, the proportion of complex congenital heart disease in the malnutrition group was higher (62.2% (56/90) vs. 47.3% (195/412), P<0.05). The postoperative mechanical ventilation time, postoperative intensive care unit (ICU) stay time, postoperative hospital stay, total length of ICU stay and total hospital stay in the malnutrition group were significantly longer than those in non-malnutrition group (all P<0.05). The proportion of egg and fish supplementation over 2 times/week within one year after the surgery was also lower in the malnutrition group (both P<0.05). Logistic regression analysis showed that mother's weight at delivery (OR=0.95,95%CI 0.91-0.99), the pre-operative WAZ≤-2 (OR=6.04, 95%CI 3.13-11.65), the complexity of the cardiac disease (OR=2.23, 95%CI 1.22-4.06), the hospital stay after the surgery over 14 days (OR=2.61, 95%CI 1.30-5.26), the types of complementary food<4 (OR=2.57, 95%CI 1.39-4.76), and the frequency of meat and fish<2 times/week (OR=2.11, 95%CI 1.13-3.93) were the risk factors associated with malnutrition within one year after the surgery. Conclusion: Mother's weight at delivery pre-operative nutritional status, complexity of cardiac disease, postoperative hospital stay, types of daily supplements and frequency of fish are risk factors associated with malnutrition within one year after surgery in children with congenital heart disease.

OBJECTIVES: To study the risk factors for postoperative delirium (POD) in children with congenital heart disease. METHODS: A prospective nested case-control study was performed on children with congenital heart disease who underwent surgery in Fuwai Hospital, Chinese Academy of Medical Sciences, from December 2020 to June 2021. The clinical data were compared between the POD group (n=114) and non-POD group (n=102). A multivariate unconditional logistic regression analysis was used to investigate the risk factors for POD in children with congenital heart disease. RESULTS: The multivariate logistic regression analysis showed that age (OR=0.951, P<0.001), gender (OR=2.127, P=0.049), number of invasive catheters per day (OR=1.490, P=0.017), degree of postoperative pain (OR=5.856, P<0.001), and preoperative parental anxiety level (OR=1.025, P=0.010) were independent risk factors for POD in children with congenital heart disease. CONCLUSIONS The risk of POD increases in children with congenital heart disease who are younger, male, have higher number of invasive catheters per day, higher degree of postoperative pain, or higher preoperative parental anxiety level.

To analyse the clinical data of reoperations in congenital heart disease and discuss the management strategy of reoperation for congenital heart disease.
 Methods: We retrospectively studied the clinical data for patients underwent reoperation in congenital heart disease in Cardiovascular Surgery, Second Xiangya Hospital, Central South University from January 2007 to December 2015. Demographic and operative details, in-hospital mortality and major postoperative complications were analysed.
 Results: A total of 8 647 congenital heart disease surgery procedures were performed, including 147 (1.7%) reoperations. Among the patients, residual septal defect repair (30 cases, 20.4%), planed staged operation (28 cases, 19.0%), and Fontan procedure (20 cases, 13.6%) were the most common kinds of reoperation. In addition, 140 (95%) operations were through repeat sternotomies, 144 (98%) patients underwent operation with cardiopulmonary bypass, and 100 (68%) with cardiac arrest. Cardiopulmonary bypass and aortic cross clamp were maintained for 21-447 (135.5±87.8) minutes and 0-202 (49.9±49.7) minutes. There were 10 in-hospital deaths with a total mortality of 6.8%. The major complications included low cardiac output syndrome (24 cases, 16.3%), renal dysfunction (7 cases, 4.8%), respiratory insufficiency (14 cases, 9.5%), unplanned reoperations for drainage of haemorrhagic cardiac tamponade (4 cases), and delayed sternal closure (2 cases).
 Conclusion: Repeat sternotomy is the main way of reoperation, but it is not a major risk for operative mortality and morbidity. Improving the management of complex malformation, standardizing the follow-up, choosing the right timing of surgery, and reducing surgical complications will help reduce the risk of reoperation.

To investigate the incidence of postoperative abnormal liver function test (aLFT) for the children with heart surgery, and to analyze the clinical characteristics and risk factors.
 Methods: A total of 143 children younger than 18 years old who underwent heart surgery in 2017 were enrolled in this study. The liver function were examined one day preoperation and consecutive 5 days after operation. The clinical data of perioperative period were recorded and the risk factors for aLFT were analyzed.
 Results: There were 43/143 (30%) cases had aLFT, including 5/143 (3.5%) acute liver injury (ALI). In the 6 liver function tests, total bilirubin, and glutamic-oxalacetic aminotransferase and glutamic-pyruvic aminotransferase increased to the peak at the first day and the second day after operation, respectively, and albumin declined to the lowest level at the fourth day after operation. aLFT happened most common at the first day after operation(22/43, 51.2%). The patients in the aLFT(+) group had smaller body size, more proportion of the risk adjustment for congenital heart sugery-1 (RACHS-1) score ≥ 3 and cyanosis, longer cardiopulmonary bypass (CPB) time, higher postoperative cardiac troponin (cTnI) value, higher inotropic score (IS), more transfusion, and longer mechanical ventilation time than those in the aLFT(-) group. The aLFT(+) group had longer ICU and hospital time, higher morbidity and mortality than those in the aLFT(-) group (P<0.05). Logistic regression showed that RACHS-1≥3, cyanosis, CPB time, cTnI, IS, transfusion, and mechanical ventilation time were the risk factors for aLFT. Multiple factor analysis showed the mechanical ventilation time was an independent risk factor for aLFT (P<0.05).
 Conclusion: aLFT is common in children after congenital heart operation, which could deteriorate to poor outcome. The mechanical ventilation time is an independent risk factor for aLFT.

OBJECTIVETo analyze the perioperative clinical data of children with congenital heart disease complicated by acute kidney injury (AKI) after cardiopulmonary bypass (CPB) surgery, and to explore potential factors influencing the prognosis.

METHODSA retrospective analysis was performed among 118 children with congenital heart disease who developed AKI within 48 hours after CPB surgery.

RESULTSIn the 118 patients, 18 died after 48 hours of surgery. Compared with the survivors, the dead children had significantly higher incidence of cyanotic disease and Risk Adjustment for Congenital Heart Surgery-1 (RACHS-1) scores before surgery; during surgery, the dead children had significantly longer CPB time and aortic cross-clamping time, a significantly higher proportion of patients receiving crystalloid solution for myocardial protection, and a significantly higher mean blood glucose level. Within 48 hours after surgery, the dead children had significantly higher positive inotropic drug scores, significantly higher creatinine values, a significantly higher incidence of stage 3 AKI, a significantly higher proportion of patients receiving renal replacement the, and significantly higher usage of blood products (P<0.05). The mortality rate of the patients increased with increased intraoperative blood glucose levels (P<0.05). Patients with intraoperative blood glucose levels >8.3 mmol/L had a significantly lower postoperative cumulative survival rate and a significantly shorter mean survival time than those with blood glucose levels ≤ 8.3 mmol/L (P<0.05).

CONCLUSIONSIntraoperative blood glucose levels are associated with the prognosis in children with congenital heart disease complicated by AKI after CPB surgery. Maintaining good intraoperative blood glucose control can improve the prognosis of the children.

OBJECTIVETo study the association between fluid overload and acute kidney injury (AKI) after congenital heart disease surgery in infants.

METHODSA retrospective analysis was performed on 88 infants aged less than 6 months who underwent a radical surgery for congenital heart disease. The treatment outcomes were compared between the infants with AKI after surgery and those without. The effect of cumulative fluid overload on treatment outcomes 2 days after surgery was analyzed. The risk factors for the development of AKI after surgery were assessed by logistic regression analysis.

RESULTSCompared with those without AKI after surgery, the patients with AKI had younger age, lower body weights, higher serum creatinine levels and higher vasoactive-inotropic score, as well as longer durations of intraoperative extracorporeal circulation and aortic occlusion (P<0.05). Compared with those without AKI after surgery, the patients with AKI had a higher transfusion volume, a higher incidence rate of low cardiac output syndrome, a longer duration of mechanical ventilation, a longer length of stay in the intensive care unit (ICU), a longer length of hospital stay, a higher application rate of extracorporeal membrane oxygenation, a higher 30-day mortality rate, and higher levels of cumulative fluid overload 2 and 3 days after surgery (P<0.05). The logistic regression analysis showed that fluid overload and low cardiac output syndrome were major risk factors for the development of AKI after surgery. The children with cumulative fluid overload >5% at 2 days after surgery had a higher incidence rate of low cardiac output syndrome, a longer duration of mechanical ventilation, a longer length of stay in the ICU, a longer length of hospital stay, and a higher mortality rate (P<0.05).

CONCLUSIONSInfants with fluid overload after surgery for congenital heart disease tend to develop AKI, and fluid overload may be associated with poor outcomes after surgery.

PURPOSE: We evaluated the hemodynamic statuses of patients after partial closure of atrial septal defects with fenestration due to pulmonary hypertension. MATERIALS AND METHODS: Seventeen adult patients underwent partial atrial septal defect closure and follow-up cardiac catheterization. We analyzed hemodynamic data and clinical parameters before and after closure. RESULTS: The median age at closure was 29 years old. The baseline Qp/Qs was 1.9+/-0.6. The median interval from the operation to the cardiac catheterization was 27 months. The CT ratio decreased from 0.55+/-0.07 to 0.48+/-0.06 (p<0.05). The mean pulmonary arterial pressure decreased from 50.0+/-11.5 mm Hg to 32.5+/-14.4 mm Hg (p<0.05), and the pulmonary resistance index decreased from 9.2+/-3.6 Wood units*m2 to 6.3+/-3.8 Wood units*m2 (p<0.05). Eleven patients (64.7%) continued to exhibit high pulmonary resistance (over 3.0 Wood units*m2) after closure. These patients had significantly higher pulmonary resistance indices and mean pulmonary arterial pressures based on oxygen testing before the partial closures (p<0.05). However, no significant predictors of post-closure pulmonary hypertension were identified. CONCLUSION: Despite improvement in symptoms and hemodynamics after partial closure of an atrial septal defect, pulmonary hypertension should be monitored carefully.

A 20-year-old female had undergone definitive surgical repair for pulmonary atresia with intact ventricular septum soon after birth. She was referred to our institution with the chief complaint of clubbing fingers. A thorough examination revealed platypnea-orthodeoxia syndrome due to an interatrial right-to-left shunt through a secundum atrial septal defect. Percutaneous closure with an Amplatzer Septal Occluder resulted in resolution of the syndrome.

OBJECTIVETo investigate the result of surgical treatment of active infective endocarditis in patients with recent cerebrovascular events, and to evaluate the optimal indication and timing of surgical intervention.

METHODSThe clinical data of 26 patients with cerebrovascular complications before surgery Between December 2007 and December 2013 were analyzed retrospectively. There were 17 male and 9 female patients, aged (42±14) years. Types of disease included single aortic valvular disease (n=8), single mitral valvular disease (n=12), multiple valvular disease (n=5), and aortic valvular disease with ventricular septal defect (n=1). Type of cerebrovascular complication included cerebral infarction (n=25) and cerebral hemorrhage (n=1). Thirty-one valves were involved in 26 patients, mechanical prosthetic valve replacement (n=25), bioprosthetic valve replacement (n=4), and mitral valve repair (n=2).

RESULTSThe interval between onset of cerebrovascular event and surgical intervention was less than 14 days (n=3), 14 to 21 days (n=13), over 21 days (n=10), and the mean was (20±4) days. There were 33 vegetations found intraoperatively. The mean size of vegetations was (10±4) mm and 19 were found in mitral valve. Two patients died in hospital. One case relapsed after 1 year and underwent reoperation for prosthetic valve endocarditis. The remaining patients recovered with cardiac function of New York Heart Association class I to II after the period of 3 months to 5 years follow-up.

CONCLUSIONSAppropriate surgery may effectively improve the outcome of IE patients with cerebrovascular complications. The surgical indications and risks of further neurologic deterioration after cardiac surgery should be assessed comprehensively before surgical intervention.

OBJECTIVETo analyze and summarize the clinical features and experience in surgical treatment of deep sternal infection (DSWI).

METHODSThis was a retrospective study. From January 2008 to December 2013, 189 patients with secondary DSWI after cardiac surgery underwent the pectoralis major muscle flap transposition in our department. There were 116 male and 73 female patients. The mean age was (54 ± 21) years, the body mass index was (26. 1 ± 1. 3) kg/m2. The incidence of postoperation DSWI were after isolated coronary artery bypass grafting (CABG) in 93 patients, after other heart surgery plus CABG in 13 patients, after valve surgery in 47 patients, after thoracic aortic surgery in 16 patients, after congenital heart disease in 18 patients, and after cardiac injury in 2 patients. Clean patients' wound and extract secretions, clear the infection thoroughly by surgery and select antibiotics based on susceptibility results, and then repair the wound with appropriate muscle flap, place drain tube with negative pressure. Of all the 189 patients, 184 used isolate pectoralis, 1 used isolate rectus, and 4 used pectoralis plus rectus.

RESULTSThe operative wounds of 179 patients were primary healing (94. 7%). Hospital discharge was postponed by 1 week for 7 patients, due to subcutaneous wound infection. Subcutaneous wound infection occurred again in 8 patients 1 week after hospital discharge, and their wounds healed after wound dressing. Nine patients (4. 7%) did not recover, due to residue of the sequestrum and costal chondritis, whom were later cured by undergoing a second treatment of debridement and pectoralis major muscle flap transposition. Eight patients died, in which 2 died of respiratory failure, 2 died of bacterial endocarditis with septicemia, 2 died of renal failure, 1 died of intraoperative bleeding leading to brain death and the 1 died of heart failure. The mortality rate was 4. 2% . The average length of postoperative hospital stay was (14 ± 5) days. The longest postoperative follow-up period was 40 months, the median time was 26 months, the follow-up rate was 83. 9% . Totally 179 patients were no-reinfected, 2 patients were reinfected because of artificial vascular rejection.

CONCLUSIONTo perform surgical debridement and then reconstruct the sternal defect with pectoralis major muscle flap actively for the patient is an effective measure to improve patient's survival rate.
