RESUMO
BACKGROUND: Coronary artery complications (CACs) in patients who undergoing prosthetic pulmonary valve implantation for congenital heart disease can lead to fetal outcomes. However, the incidence of and risk factors for CACs in these patients remain unknown. METHODSâANDâRESULTS: A retrospective cohort study was conducted on patients who underwent cardiac computed tomography or invasive coronary angiography after prosthetic pulmonary valve implantation at Seoul National University Hospital from June 1986 to May 2021. Among 341 patients, 25 (7.3%) were identified with CACs, and 2 of them died. Among the patients with CACs, congenital coronary anomalies and an interarterial course of the coronary artery were identified in 11 (44%) and 18 (72%) patients, respectively. Interarterial and intramural courses of the coronary artery were associated with a 4.4- and 10.6-fold increased risk of CACs, respectively. Among patients with tetralogy of Fallot and pulmonary atresia, the aortic root was rotated further clockwise in patients with coronary artery compression compared to those without it (mean [±SD] 128.0±19.9° vs. 113.5±23.7°; P=0.024). The cut-off rotation angle of the aorta for predicting the occurrence of coronary artery compression was 133°. CONCLUSIONS: Perioperative coronary artery evaluation and prevention of CACs are required in patients undergoing prosthetic pulmonary valve implantation, particularly in those with coronary artery anomalies or severe clockwise rotation of the aortic root.

BACKGROUND: A high burden of physical, mental, and occupational health problems among migrant workers has been well-documented, but data on undocumented migrant workers are limited and their well-being has rarely been compared to that of the general population. METHODS: Using data from a cross-sectional survey of non-professional migrant workers in South Korea in early 2021, we described their physical, psychological, social well-being and health behaviors across a wide range of outcomes, including self-rated health, occupational injury, cigarette smoking, heavy alcohol consumption, meal pattern, happiness, mental illness, social support, and social participation. The outcomes were first compared between documented and undocumented migrant workers in generalized linear regressions adjusting for potential confounders. Then, the well-being of the migrant workers was compared against that of the general population using data from the Korean Happiness Survey, which is a nationally representative survey of the South Korean general population conducted in late 2020. The parametric g-formula was performed to adjust for potential confounders. RESULTS: After adjusting for potential confounders, the undocumented migrant workers were less likely to be happy or participate in social communities, and much more likely to have anxiety or depression, smoke cigarettes, or engage in heavy alcohol consumption than the documented migrant workers. When compared to the general South Korean population, an evident social gradient emerged for happiness and mental illness; the undocumented experienced the worst outcome, followed by the documented, and then the general population. Also, the undocumented migrant workers were more likely to smoke cigarettes than the general population. CONCLUSION: The undocumented migrant workers face considerably greater challenges in terms of mental health and happiness, demonstrate higher rates of risky health behaviors such as smoking and heavy drinking, and experience a lack of social support and community integration. A stark social gradient in happiness, mental illness, and cigarette smoking exists among the documented, undocumented migrant workers and the general population in South Korea. Socio-structural factors are likely to play a crucial role in contributing to the suboptimal level of overall well-being of undocumented migrant workers. Policy-level interventions as well as interpersonal efforts are in urgent need.

BACKGROUNDS AND OBJECTIVES: The "Fast track" protocol is an early extubation strategy to reduce ventilator-associated complications and induce early recovery after open-heart surgery. This study compared clinical outcomes between operating room extubation and ICU extubation after open-heart surgery in patients with CHD. METHODS: We retrospectively reviewed 215 patients who underwent open-heart surgery for CHDs under the scheduled "Fast track" protocol between September 2016 and April 2022. The clinical endpoints were post-operative complications, including bleeding, respiratory and neurological complications, and hospital/ICU stays. RESULTS: The patients were divided into operating room extubation (group O, n = 124) and ICU extubation (group I, n=91) groups. The most frequently performed procedures were patch closures of the atrial septal (107/215, 49.8%) and ventricular septal (89/215, 41.4%) defects. There were no significant differences in major post-operative complications or ICU and hospital stay duration between the two groups; however, patients in group I showed longer mechanical ventilatory support (0.0 min vs. 59.0 min (interquartile range: 17.0-169.0), p < 0.001). Patients in Group O showed higher initial lactate levels (3.2 ± 1.7 mg/dL versus 2.5 ± 2.0 mg/dL, p = 0.007) and more frequently used additional sedatives and opioid analgesics (33.1% versus 19.8%, p = 0.031). CONCLUSIONS: Extubation in the operating room was not beneficial for patients during post-operative ICU or hospital stay. Early extubation in the ICU resulted in more stable hemodynamics in the immediate post-operative period and required less use of sedatives and analgesics.

BACKGROUND: Existing evidence highlights that the COVID-19 pandemic is associated with a large reduction in healthcare utilization for routine and less-urgent services around the world including Korea. During the COVID-19 pandemic, delayed and foregone healthcare are driven by various factors, and risk perception, a complex psychological construct, is one of them. The aim of this study was to examine how COVID-19 risk perceptions influence delayed and foregone care during the pandemic in Korea. METHODS: The Koreans' Happiness Survey (KHS) 2020 was used to analyze responses from 13,491 individuals over 19 years of age residing in Korea. To assess delayed and foregone care, self-reported delayed or foregone care after the COVID-19 outbreak was used. COVID-19 risk perceptions were analyzed in terms of fear and severity of the pandemic based on responses from the participants. Logistic regression models, stratified by gender, were used to examine the relationship between COVID-19 risk perception and delayed/foregone healthcare. RESULTS: Among the total 13,491 individuals included in the study, 4.0% (n = 541) reported delayed and foregone care in 2020. The results showed that higher level of fear of COVID-19 was associated with an increased likelihood of reporting delayed and foregone care in Korean adults (OR = 1.36, 95% CI = 1.08-1.73). The gender-stratified model revealed that greater fear of COVID-19 was associated with higher odds of delayed and foregone healthcare (OR = 1.71, 95%CI = 1.23-2.39) among women while the perceived severity did not have any association. However, the perceived severity was associated with a higher likelihood of delayed and foregone care in men (OR = 1.17, 95%CI = 1.04-1.32), but no association was found between fear of COVID-19 and delayed and foregone healthcare in men. CONCLUSIONS: To ensure the timely use of any needed healthcare services, it is worth considering establishing policy interventions to mitigate unnecessary fear and worries about COVID-19. This can be achieved by providing accurate information on the virus, protective measures, and treatment.

OBJECTIVES: Dilatation of the aortic root structures or ascending aorta is often observed in patients with Fallot-type anomalies. We aimed to determine the dilation rate of the aortic structures and investigate strategies for managing this phenomenon. METHODS: In this retrospective study, we enrolled 66 out of 801 patients who underwent corrective surgery for Fallot-type anomalies (tetralogy of Fallot [TOF] and Fallot-type double outlet right ventricle [DORV]) between 2004 and 2020. These 66 patients had follow-up cardiac computed tomography (CT) angiography images taken at least 5 years after the initial CT study. We analyzed the diameters and aortic cross-sectional area/height ratio (AH) of the aortic annulus, sinus of Valsalva, sinotubular junction, and ascending aorta between the initial and follow-up CT scans. "Dilatation" was defined as a z-score over 2 for each aortic structure. RESULTS: The median age at the initial and follow-up CT scans was 5.9 years (interquartile range [IQR]: 0.4 ~ 12.4) and 15.9 years (IQR 9.3 ~ 23.4), respectively. The median CT interval (from initial to latest CT) was 9.5 years (IQR 6.6 ~ 12.0). The sinus of Valsalva exhibited the most significant dilation (32.8 mm at follow-up CT) over the study period. The AH ratio increased significantly in all four aortic structures. The patient's age was significantly associated with higher AH in the follow-up CT. Aortic dilatation was present in 74.2% of patients at the initial CT and increased to 86.4% at the follow-up CT. CONCLUSION: In Fallot-type anomalies, the AH ratio of aortic root structures significantly increased over an average period of approximately 9.5 years. The number of patients diagnosed with aortic dilatation also increased. Based on our observations in this study, these patients' group should be considered for more frequent follow-up examinations, as significant dilatation could occur in their mid-20 s.

BACKGROUND: To avoid rhythm disturbance, sutures for ventricular septal defect closure have been traditionally placed 2â¼5 mm or more away from the edge of the ventricular septal defect. However, the traditional suturing method appears to induce right bundle branch block and tricuspid valve regurgitation after ventricular septal defect closure more than our alternative technique, shallow suturing just at the edge of the ventricular septal defect (shallower bites at the postero-inferior margin). We aimed to verify our clinical experience of perimembranous ventricular septal defect repair. METHODS: The alternative shallow suturing method has been applied since 2003 at our institution. We retrospectively reviewed the clinical data of 556 isolated perimembranous ventricular septal defect patients who underwent surgical closure from 2000 to 2019. We investigated the postoperative occurrence of right bundle branch block or progression of tricuspid regurgitation and analysed risk factors for right bundle branch block and tricuspid regurgitation. RESULTS: Traditional suturing method (Group T) was used in 374 cases (66.8%), and alternative suturing method (Group A) was used in 186 cases (33.2%). The right bundle branch block occurred more frequently in Group T (39.6%) than in Group A (14.9%). In multivariable logistic regression analysis, Group T and patch material were significant risk factors for late right bundle branch block. More patients with progression of tricuspid regurgitation were found in Group T. CONCLUSIONS: Shallow suturing just at the edge of the ventricular septal defect may reduce the rate of right bundle branch block occurrence and tricuspid regurgitation progression without other complications.

BACKGROUND: Prioritizing global health is important for positive health outcomes. Doctors play a pivotal role in addressing health issues that they need to recognize the importance of global health practice. However, medical education in global health is still in its early stages in many countries, including South Korea. METHODS: This study is a quantitative cross-sectional study. Medical students were recruited from all 40 Korean medical schools and data collection was conducted in 2021. Stratified proportional quota sampling was employed as the sampling method. The study examined medical students' interest in global health as the dependent variable. Independent variables included whether individuals had taken global health courses as part of their medical curriculum, while covariates included student background and institutional factors. Logistic regression was used to determine if taking a global health class was associated with global health interests. RESULTS: The study included 2450 participants and almost 32% of medical students (n = 781) were interested in global health. Taking global health classes in school was associated with a higher likelihood of developing an interest in global health (OR: 1.29, 95% CI: 1.00-1.67). The likelihood of being interested in global health decreased across the academic year (OR: 0.70, 95% CI: 0.53-0.94). Individuals in graduate entry programs were associated with an interest in global health (OR: 1.32, 95% CI: 1.01-1.72). CONCLUSION: This study provides the first comprehensive nationwide assessment of medical students' perspectives on global health education in South Korea. The findings underscore the importance of early and sustained exposure to global health topics in medical education in fostering interest in global health. These results can serve as valuable evidence for medical educators seeking to integrate global health education into their curricula.

BACKGROUND: Pulmonary valve replacement (PVR) is often performed in patients with repaired tetralogy of Fallot (TOF). Concomitant tricuspid valvuloplasty (TVP) in those with tricuspid regurgitation (TR) at the time of PVR is still controversial. METHOD: We retrospectively reviewed clinical records of patients who underwent PVR between 2001 and 2012. We analyzed the impact of concomitant TVP on the tricuspid valve function and right ventricle function and size in mid-term. RESULTS: 119 patients with mild to moderate TR at the time of PVR were enrolled. 33 patients underwent concomitant TVP (TVP group) and 86 patients underwent PVR alone (no-TVP group). There was a significant reduction of TR (p < 0.001) and right ventricular end-diastolic volume index (RVEDVi) (p < 0.001). However, in patients who showed prosthetic pulmonary valve (PV) failure at the last follow-up, there was no significant decrease in TR regardless of concomitant TVP. In the patients with preserved prosthetic PV function, TR was significantly improved (p < 0.001 in both groups). The multivariable analysis showed that significant risk factors for recurrence of significant TR were preoperative moderate TR and prosthetic PV failure. CONCLUSIONS: After PVR in repaired TOF patients, there was an improvement in the degree of TR and the RVEDVi. Concomitant TVP at the time of PVR may not be able to prevent the recurrence of TR when prosthetic PV failure occurs; however, it may effectively preserve tricuspid valve function until that time.

The surgical treatment for young patients with aortic valve diseases has not been standardized because of differences in the patients' growth. We aimed to investigate short-term results of aortic valve repair with leaflet extension techniques. From October 2017 to June 2020, we performed aortic valve repair with leaflet extension technique in 15 consecutive patients with a median age of 13 years (range, 33 months-27 years). Among them, all had moderate or severe aortic regurgitation (AR), eight had concomitant aortic stenosis, and 12 underwent prior cardiac operations. The leaflet patch design has been modified from separate patch design to single patch design. No early and late deaths were reported, no re-operations were performed, and temporary ectopic atrial arrhythmia was the only early complication noted. The patients were discharged with less than moderate AR after a median postoperative period of 5 (range, 3-7) days. All the patients were New York Heart Association class I after a median follow-up period of 17.3 (range, 4.4-34.6) months. However, two patients progressed to moderate AR postoperatively at 6 and 30 months, respectively, after which one was treated with single patch technique. Among the remaining patients, six had trace, six had mild, and one had mild-to-moderate AR. Aortic valve repair with leaflet extension is acceptable in young patients. Our single patch design was easy to manipulate and showed good short-term results. Long-term follow-up is required to further confirm the efficacy of this technique.

BACKGROUND: Although coronary artery bypass grafting is not frequently performed in children, Kawasaki disease is one of the most common indications for coronary artery bypass grafting in children. Here, we reviewed the long-term clinical outcomes including graft patency after coronary artery bypass grafting. METHODS: Between March 2004 and March 2013, six patients with Kawasaki disease underwent coronary artery bypass grafting. All patients were male. Their median age was 13.0 years (interquartile range, 7.8-17.8 years) at the timing of coronary artery bypass grafting, and the median age at the onset of Kawasaki disease was 3.3 years (interquartile range, 1.0-7.0 years). Four patients presented with multiple lesions including aneurysms. RESULTS: The median follow-up duration was 12.1 years (interquartile range, 9.5-13.1 years), and there were no operative complications or overall mortality. One patient had pre-operative symptoms such as exertional chest pain and dyspnoea on exertion, whereas one patient had ventricular tachyarrhythmia. There was an improvement in subjective symptoms after surgery in two patients. The left internal thoracic artery, right internal thoracic artery, and saphenous vein were used in five (83.3%), one (16.7%), and two (33.3%) cases, respectively. In all six patients, post-operative single-photon emission CT findings showed improved perfusion compared with pre-operative single-photon emission CT. All grafts were patent as confirmed by coronary angiography or CT angiography. CONCLUSIONS: Coronary artery bypass grafting could be a good surgical option in children with coronary lesions caused by Kawasaki disease in terms of graft patency and myocardial perfusion.

INTRODUCTION: Effective teamwork in paediatric cardiac surgery is known to improve team performance and surgical outcomes. However, teamwork in low- and middle-income countries (LMICs), including Mongolia, is understudied. We examined multiple dimensions of teamwork to inform a team-based training programme to strengthen paediatric cardiac surgical care in Mongolia. METHODS: We used a mixed-methods approach, combining social network analysis and in-depth interviews with medical staff, to explore the structure, process, quality, and context of teamwork at a single medical centre. We conceptualised the team's structure based on communication frequency among the members (n = 24) and explored the process, quality, and context of teamwork via in-depth interviews with select medical staff (n = 9). RESULTS: The team structure was highly dense and decentralised, but the intensive care unit nurses showed high betweenness-centrality. In the quality and process domain of teamwork, we did not find a regular joint decision-making process, leading to the absence of common goals among the team members. Although role assignment among the medical staff was explicit, those strictly defined roles hindered active communication about patient information and responsibility-sharing. Most interviewees did not agree with the organisational policies that limited discussions among team members; therefore, medical staff continued to share training and work experiences with each other, leading to strong and trustworthy relationships. CONCLUSION: The findings of this study underscore the importance of well-structured and goal-oriented communication between medical staff, as well as the management of the quality of collaboration within a team to increase teamwork effectiveness in paediatric cardiac surgery teams in LMICs.

BACKGROUND: Surgery can correct congenital heart defects, but disease management in low- and middle-income countries can be challenging and complex due to a lack of referral system, financial resources, human resources, and infrastructure for surgical and post-operative care. This study investigates the experiences of caregivers of children with CHD accessing the health care system and pediatric cardiac surgery. METHODS: A qualitative study was conducted at a teaching hospital in Ethiopia. We conducted semi-structured interviews with 13 caregivers of 10 patients with CHD who underwent cardiac surgery. We additionally conducted chart reviews for triangulation and verification. Interviews were conducted in Amharic and then translated into English. Data were analyzed according to the principles of interpretive thematic analysis, informed by the candidacy framework. RESULTS: The following four observations emerged from the interviews: (a) most patients were diagnosed with CHD at birth if they were born at a health care facility, but for those born at home, CHD was discovered much later (b) many patients experienced misdiagnoses before seeking care at a large hospital, (c) after diagnosis, patients were waiting for the surgery for more than a year, (d) caregivers felt anxious and optimistic once they were able to schedule the surgical date. During the care-seeking journey, caregivers encountered financial constraints, struggled in a fragmented delivery system, and experienced poor service quality. CONCLUSIONS: Delayed access to care was largely due to the lack of early CHD recognition and financial hardships, related to the inefficient and disorganized health care system. Fee waivers were available to assist low-income children in gaining access to health services or medications, but application information was not readily available. Indirect costs like long-distance travel contributed to this challenge. Overall, improvements must be made for district-level screening and the health care workforce.

Atrioventricular valve regurgitation (AVVR) is associated with increased morbidity and mortality in patients with single ventricle physiology. The purpose of this study was to evaluate the long-term results of the surgical management of AVVR and to analyze the effects of AV valve replacement. The medical records of 38 single ventricle patients who underwent atrioventricular valve surgery more than once between January 2001 and March 2018 were retrospectively reviewed. We analyzed and compared clinical data of patients who underwent valve replacement as an initial treatment (n = 8) for AVVR with patients who initially underwent valve repair (n = 30). The median follow-up duration was 98.1 months (range, 0.9-209.6 months). There was one early mortality and seven late mortalities. Freedom from reoperation between the two groups at 15 years of follow-up was significantly different: 18.3% in the repair group and 100% in the replacement group (p = 0.013). The replacement group showed a better overall survival rate (100%) at 15 years than the repair group (68.5%) without statistical significance (p = 0.097). All mortalities occurred in the repair group. Nine patients in the repair group (30%) and one patient in the replacement group (12.5%) showed preoperative ventricular dysfunction. RV-type single ventricle with atrioventricular (AV) valve annular dilatation was found out as a risk factor of AVV replacement both in univariate (p = 0.04) and multivariate (p = 0.004) analysis. AV valve replacement might be considered as a primary treatment option for patients who have an annular dilation with an RV-type single ventricle rather than repeated valvuloplasty.

Although the clinical outcomes of truncus arteriosus (TA) repair have been improving, few data are available on long-term outcomes after truncus arteriosus repair in the current era. This study evaluated long-term outcome after repair of TA. Fifty-one patients underwent total correction from April 1982 to June 2018. Since 2003, perioperative strategy has changed to minimal priming volume, modified ultrafiltration, and early total repair (n = 26). Mortality and reoperation rates were analyzed before and after 2003. There were 8 hospital deaths after initial operation, all before 1997. During the mean follow-up of 9.8 years, there were 2 deaths. The Kaplan-Meier estimate of survival among all hospital survivors was 94.7% at 5 years and 88.0% at 20 years. A significant independent risk factor for early mortality was operation before 2003 (Hazard ratio (HR) 9.710, p = 0.041) and REV operation (HR 8.000, p = 0.028). Freedom from reoperation for conduit change and TV repair were 88.3% and 41% at 1 and 5 years, and 96.2% and 85.4% at 1 and 5 years, respectively. After 2003, younger age and conduit choice were risk factors for conduit-related reoperation. Initial preoperative TV regurgitation was independent risk factor for sequential TV repair. Patients with TA can undergo total repair of TA with excellent results, especially in current era. Most of the patients require conduit-related reoperations. Younger age and the methods of RVOT reconstruction were risk factors for conduit-related reoperations. TV repair is necessary in limited patients, and initial regurgitation was a risk factor.

BACKGROUND: Nepal has a high prevalence of congenital anomaly contributing to high infant mortality. Ultrasound, an important tool to detect congenital anomalies and manage maternity-related risk factors, is not properly used in Nepal because Nepali doctors have limited opportunities for learning ultrasound techniques. Hence, we developed and implemented an ultrasound education program from 2016 to 2018. The objective of this study is to evaluate the education program using the Reach, Effectiveness, Adoption, Implementation, and Maintenance (RE-AIM) framework. METHODS: We conducted a mixed-method study to evaluate each component of RE-AIM. The team collected quantitative data from administrative records, tests, surveys, and an online follow-up survey. Qualitative data were collected from individual in-depth interviews at least a year after the program. The proportions, means, and t-tests were used for quantitative data, and thematic coding for qualitative data. RESULTS: A total of 228 healthcare workers representing 27.3% of the districts of Nepal were reached from 2016 to 2018. The program improved participants' knowledge (29.3, 8.7, and 23.8 increases out of 100, each year, p< 0.001, n=85) and self-confidence (0.6, 0.3, 1.3 increases out of 4.0, p< 0.01, n=111). The participants were highly satisfied with the program (4.2, 4.1, and 4.0 out of 5.0, n=162). Among the respondents of the online follow-up survey (n=28), 60.7% had used ultrasound in their daily practice after the education program, and a medical institution established an ultrasound training center. The absence of clear accreditation and practical guidelines in ultrasound use were presented as barriers for adoption and maintenance. CONCLUSION: The program was successful in improving participant's knowledge and self-confidence in ultrasound techniques and showed great potential for the adoption and maintenance of the techniques in their practice. Continuous implementation of the program and institutional policy changes to facilitate ultrasound use may increase the ultrasound use and improve ultrasound service quality in Nepal.

Abiotrophia defectiva is a rare pathogen of infective endocarditis (IE) but is frequently involved in embolic complication and valvular dysfunction. IE caused by A. defectiva in children is poorly studied. This study reports four cases of A. defectiva IE in children and reviews previously reported five pediatric cases of A. defectiva IE. Most of the patients presented with a subacute course, with prolonged fever or atypical symptoms. Eight patients had embolic complications at presentation. All nine children were treated with combination antimicrobial therapy and six of them received surgical intervention. All patients recovered well without relapse. A. defectiva should be considered in children with infective endocarditis, especially in those with atypical presentations. As complications are frequent and more than half of the patients need surgical treatment, prompt diagnosis along with appropriate treatment is necessary.

BACKGROUND: As a result of advances in pediatric care and diagnostic testing, there is a growing population of adults with congenital heart disease (ACHD). The purpose of this study was to better define the epidemiology and changes in the trend of hospitalizations for ACHD in Korean society. METHODS: We reviewed outpatient and inpatient data from 2005 to 2017 to identify patient ≥18 years of age admitted for acute care with a congenital heart disease (CHD) diagnosis in the pediatric cardiology division. We tried to analyze changes of hospitalization trend for ACHD. RESULTS: The ratio of outpatients with ACHD increased 286.5%, from 11.1% (1748/15,682) in 2005 to 31.8% (7795/24,532) in 2017. The number of ACHD hospitalizations increased 360.7%, from 8.9% (37/414) in 2005 to 32.1% (226/705) in 2017. The average patient age increased from 24.3 years in 2005 to 27.4 in 2017. The main diagnosis for admission of ACHD is heart failure, arrhythmia and Fontan-related complications. The annual ICU admission percentage was around 5% and mean length of intensive care unit (ICU) stay was 8.4 ± 14.6 days. Mean personal hospital charges by admission of ACHD increased to around two times from 2005 to 2017. (from $2578.1 to $3697.0). Total annual hospital charges by ACHD markedly increased ten times (from $95,389.7 to $831,834.2). CONCLUSIONS: The number of hospital cares for ACHD dramatically increased more than five times from 2005 to 2017. We need preparations for efficient healthcare for adults with CHD such as a multi-dimensional approach, effective communication, and professional training.

BACKGROUND: Perioperative dexmedetomidine use has been reported to reduce the incidence of postoperative acute kidney injury after adult cardiac surgery. However, large-scale randomized controlled trials evaluating the effect of dexmedetomidine use on acute kidney injury in pediatric patients are lacking. AIMS: We investigated whether intraoperative dexmedetomidine could reduce the incidence of acute kidney injury in pediatric cardiac surgery patients. METHODS: In total, 141 pediatric patients were randomly assigned to dexmedetomidine or control groups. After anesthetic induction, patients in the dexmedetomidine group were administered 1 µg/kg of dexmedetomidine over 10 minutes and an additional 0.5 µg/kg/h of dexmedetomidine during surgery. Additionally, 1 µg/kg of dexmedetomidine was infused immediately after cardiopulmonary bypass was initiated. The incidence of acute kidney injury was defined following Kidney Disease Improving Global Outcomes guidelines. RESULTS: The final analysis included 139 patients. The incidence of acute kidney injury did not differ between dexmedetomidine and control groups (16.9% vs 23.5%; odds ratio 0.661; 95% CI 0.285 to 1.525; P = .33). Similarly, neither the incidence of abnormal postoperative estimated glomerular filtration rate values (P = .96) nor the incidence of arrhythmia, mechanical ventilation duration, length of stay in the intensive care unit, and hospitalization differed between the two groups. CONCLUSIONS: Intraoperative dexmedetomidine did not reduce acute kidney injury incidence in pediatric cardiac surgery patients.

Despite improvements in valve repair techniques, conditions in which infants and children need for mechanical valve replacement (MVR) are still present. We analyzed supra-annular MVR outcomes in infants and children with small annulus and compared them with conventional annular MVR outcomes. Data were collected retrospectively from medical records of infants and children (weighing < 20 kg) who underwent atrioventricular valve replacement with mechanical valve in Seoul National University Children's Hospital between December 1984 and January 2019. We identified 8 patients (median age 20 months, median weight 10.2 kg) who underwent supra-annular MVR with polytetrafluoroethylene graft (supra-annular group). The patients were diagnosed with congenital mitral valve malformation (5 patients), complete atrioventricular septal defect (2 patients), and functional single ventricle (1 patient). The implanted mechanical valve size ranged from 16 to 23 mm. Thirty-three patients (median age 40 months, median weight 13 kg) underwent conventional annular MVR (annular group). The survival rate was not significantly different between the supra-annular and annular groups (75.0 vs 78.8%, P = 0.816). In patients with biventricular repair (7 patients with supra-annular MVR and 28 patients with annular MVR), mechanical valve-to-mitral valve annulus size ratio was higher in the supra-annular group than in the annular group (1.24 ± 0.30 vs 0.96 ± 0.22, P = 0.035). No coronary complication or heart block were observed in the supra-annular group. Supra-annular MVR with polytetrafluoroethylene graft may be a feasible surgical option in children with a small annulus when valve repair is unsuccessful.

Though ventricular assist devices (VADs) are an important treatment option for acute heart failure, an extracorporeal membrane oxygenator (ECMO) is usually used in pediatric patients for several reasons. However, a temporary centrifugal pump-based Bi-VAD might have clinical advantages versus ECMO or implantable VADs. From January 2000 to July 2018, we retrospectively reviewed 36 pediatric patients who required mechanical circulatory support (MCS) for acute heart failure. Cases with postoperative MCS were excluded. Since 2016, we have tried to immediately add a right VAD rather than ECMO, when the patients begin to present features of right heart failure after left VAD support started in cases that the patients' respiratory function did not require an oxygenator. Original diagnoses included dilated cardiomyopathy (n = 18), myocarditis (n = 11), and others (n = 7). Eleven patients were supported by Bi-VAD, and 25 patients were supported by ECMO; of these. Four patients were successfully weaned from VAD, and 10 patients were weaned from ECMO. Eleven patients underwent heart transplantation. Overall, we have 15 (41.7%) early mortalities. There were no significant differences in early mortality, morbidity, and weaning rate between the Bi-VAD group and the ECMO group. During the support, patients with Bi-VADs significantly required fewer platelets and showed less hemolysis than ECMO patients. Patients with myocarditis were successfully weaned from Bi-VAD support and bridged to transplantation thereafter. A temporary centrifugal pump-based Bi-VAD was clinically comparable to ECMO for pediatric patients with acceptable pulmonary function.
