Neurodevelopmental assessment of children with congenital heart diseases using Trivandrum developmental screening chart.

Objectives: Congenital heart diseases (CHDs) are one of the most important congenital anomalies in children which have high-risk for neurodevelopment delay. This study was conducted to determine the proportion of developmental delay in children with CHD and comparison of delay between acyanotic and cyanotic heart diseases in children. Materials and Methods: A cross-sectional study was conducted on children admitted in pediatric ward of rural hospital from 6 month to 6 years of age who are diagnosed with CHD by 2D ECHO and further classified into acyanotic congenital heart disease (ACHD) and cyanotic congenital heart disease (CCHD). Neurodevelopmental assessment was done using Trivandrum development screening chart (TDSC). Results: Out of total 50 children in study population, 24 children had TDSC delay, distribution as 11 (22%) ACHD and 13 (26%) CCHD. Out of 24 children in the age group of 0-3 years, 13 (54.2%) were ACHD and 11 (45.8%) were CCHD. Out of 26 children in the age group of 3-6 years, 15 (57.7%) were ACHD and 11 (42.3%) were CCHD. Among different ACHD included in the study population (0-3 years) children with ventricular septal defect (VSD) were maximum (n = 5) next in the decreasing order was atrial septal defect (ASD) (n = 3). ACHD included in the study population (3-6 years) children with VSD was maximum (n = 6) next in the order was ASD (n = 4). Proportion of delay in children with ACHD was 22% as compared to 26% in children with CCHD. Conclusion: There is a high proportion of neurodevelopmental delay in children with CHD which can be detected using TDSC which is a simple screening tool and can be used by any health-care professional without training for the assessment of neurodevelopmental outcome in these children. Delay was more in children with CCHD than ACHD.

Neuraxial anesthesia in Lutembacher's syndrome? Yes, we can!

Lutembacher's syndrome is a rare congenital cardiac syndrome comprising of a combination of an atrial septal defect complicated by congenital or acquired mitral stenosis. The applied physiology of the patient depends upon the severity and the interactions of the lesions. They pose certain difficulties to the administration of both general or neuraxial anesthesia. A preference of one form of anesthesia over the other should be based on the understanding of the physiology of the patient. There should not be an orthodox avoidance of neuraxial anesthesia in complex cardiac pathologies as general anesthesia can be associated with certain complications of its own. Here, we report our successful experience of neuraxial anesthesia being administered in a patient with Lutembacher's syndrome.

Neurodevelopmental Assessment in Children With Congenital Heart Disease by Applying the Denver Developmental Screening Test 2: A Prospective Cross-Sectional Study.

Background Congenital heart conditions often cause developmental delays and impact neurodevelopment throughout one's lifetime. Hence, it is crucial to analyze the impact that heart defects have on the developing brain of a child. The present cross-sectional study was undertaken given the paucity of studies on the developmental status in children with congenital heart diseases (CHDs) in central India, where we tried to evaluate and compare the prevalence of neurodevelopmental delay in individuals with different congenital cardiac disorders. The objectives of our study were, firstly, to utilize the Denver Developmental Screening Test 2 (DDST-2) to evaluate the neurodevelopmental conditions in children with CHD; secondly, to compare the neurodevelopmental state of children with acyanotic CHD (ACHD) and cyanotic CHD (CCHD); and thirdly, to ascertain the prevalence of developmental delay in children with CHD. Methodology The study population comprised children aged six months to six years with two-dimensional (2D) echocardiography confirmation of CHD; those who were critically ill, had genetic syndromes, and were not willing to participate in the study were excluded. The neurodevelopmental assessment was conducted using the DDST-2. The screening looked at each patient's progress in four areas: personal-social, fine motor-adaptive, language, and gross motor. Based on these observations, results were obtained and interpreted. Result Out of 82 children with CHD, the prevalence rate of developmental delay according to the DDST-2 was found to be maximum in the gross motor domain and the least affected in the social domain, which was similar to the analysis of developmental delay by developmental quotient (DQ). The comparative analysis of developmental delay in ACHD and CCHD according to the DDST-2 showed a significant P value only in the gross motor domain. Conclusion The DDST-2 is a straightforward screening tool for determining how well-developed infants with CHD are. The gross motor domain is the most frequently damaged in ACHD and CCHD, followed by the fine motor domain, and the social domain is the least affected. Cyanotic CHD patients are more susceptible to developmental delay than children with ACHD.

Association between type of congenital heart disease with child growth and development status: A cross-sectional study in Medan, Indonesia.

Congenital heart disease (CHD) is a congenital disorder primarily affecting newborns and children. Children with CHD have a greater risk of experiencing growth delays or disorders compared to healthy children. CHD also affects various aspects of a child's development. The aim of this study was to determine the association of CHD types (cyanotic and acyanotic) with the growth and development status of children. A cross-sectional study was conducted among CHD patients at a national reference hospital in Sumatra, H. Adam Malik General Hospital in Medan, Indonesia. The children's growth status was assessed using the WHO growth chart, and the developmental condition was evaluated through the Denver Developmental Screening Test-II. Chi-squared test and Fisher's exact test were used to assess the association between the type of CHD with growth and development status in children. Using a consecutive sampling method, a total of 53 individuals were included in this study. Almost half of CHD patients (48.1%) were within the age group of 0-2 years and more than half (61.1%) were girls. Acyanotic CHD (74.1%) was more prevalent than cyanotic CHD (25.9%), with ventricular septum defect (VSD) as the most common diagnosis. A total of 37% of children with CHD suffered from malnutrition, whereas the remaining 62.9% had good nutrition. The Denver Developmental Screening Test-II indicated that 81.4% of the children were normal, whereas 18.5% had developmental disorders. Our data suggested a significant association between cyanotic CHD and poor growth status in children based on weight-for-age, weight-for-length, and body mass index (BMI)-for-age. However, there was no association between the type of CHD and developmental status in children. This study highlights that the type of CHD is significantly associated with the growth status of children, but not with their developmental status.

Mitochondrial Dysfunction in Cyanotic Congenital Heart Disease: A Promising Therapeutic Approach for the Future.

Congenital heart disease (CHD) is one of the most specific and yet challenging fields of heart surgery. Apart from the known clinical approaches, including surgery, a significant scale of regenerative therapeutic options is available, which increase the number of cardiomyocytes and restore cardiac function. Although it has been revealed in recent years that mitochondrial transplantation can be used as a promising treatment option in this disease group, there is no clinical evidence for the significance of mitochondrial function in myocardial tissue of patients with CHD regarding cardiac surgery. In this study, mitochondrial morphology and function, myocardial fibrosis, and myocyte atypia were evaluated in myocardial biopsy tissue of pediatric patients with cyanotic and acyanotic CHD, five from each group. After histopathological evaluation of myocardial tissue specimens, mitochondrial morphology and network were analyzed by immunofluorescence staining using an anti-Tom20 antibody, electron transport chain complexes of myocardium were examined by cytochrome c oxidase/succinate dehydrogenase staining, and the amount of ATP was measured by bioluminescence assay. In addition, cardiac markers have been tested to be reviewed as a potential indicator for postoperative follow-up. Myocyte atypia and fibrosis were classified on a scale of 1 to 4. In this study, unlike patients with acyanotic CHD, alterations in mitochondrial network and reduction in ATP production were detected in all pediatric patients with cyanotic CHD. A statistically significant correlation was also determined between mitochondrial dysfunction and cardiac markers. These findings may be assumed as a promising pathway for evaluating the relationship between mitochondrial dysfunction and cyanotic CHD.

Neutrophil-Lymphocyte Ratio in Congenital Heart Surgery: What Is Known and What Is New?

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

[Cor triatriatum sinister, case report]. / Cor triatriatum sinister, reporte de un caso.

We report a case of cor triatriatum sinister associated with anomalous pulmonary venous drainage in an adult patient who presented with palpitations, lower limb edema, dyspnea, orthopnea, bendopnea and ascites. The clinical picture began with episodes of atrial fibrillation, associated with rehospitalizations for right heart failure, so angiotomography and transesophageal echography were requested, which led to the final diagnosis. The surgical approach was performed by total excision of the multifenestrating fibromuscular septum and double valvular plasty, due to severe mitral and tricuspid insufficiency, which improved the patient's clinical condition. The importance of considering this acyanotic congenital heart disease within the differential diagnosis of the causes of right heart failure originating in the left atrium is recognized.

Hematological indices in pediatric patients with acyanotic congenital heart disease: a cross-sectional study of 248 patients.

Background: Congenital heart disease CHD is a significant cause of mortality and morbidity in children worldwide. Patients with congenital heart disease may develop hematological problems, including thrombocytopenia and neutropenia. In addition, several studies indicate the higher frailty of patients with CHDs to infections and malignancies. Nevertheless, the mechanisms of immune system changes in these patients have remained in the shadow of uncertainty. Moreover, very few studies have worked on cytopenia in CHD. This study has assessed the frequency of thrombocytopenia, neutropenia, lymphopenia, and anemia in pediatric patients with acyanotic congenital heart disease ACHD prior to open-heart surgery. Methods: This cross-sectional study was handled in the Pediatric Cardiology Clinic, Tehran University of Medical Sciences, during pre-operation visits from 2014 till 2019. Two hundred forty-eight children and adolescents with acyanotic congenital heart disease before open-heart surgery met the criteria to enter the study. Results: A total of 191 (76.7%) patients with Ventricular Septal Defects (VSD), 37 (14.85%) patients with Atrial Septal Defects (ASD), and 20 (8.11%) patients with Patent Ductus Arteriosus (PDA) were enrolled in this study. The median age was 23.87 months. Thrombocytopenia and neutropenia were found, respectively, in 3 (1.2) and 23 (9.2%) patients. Hemoglobin level and lymphocyte count were significantly lower in patients with neutropenia than patients with normal neutrophil count (P value = 0.024 and P value = 0.000). Significant positive correlations were found between neutropenia and anemia. There were no correlations between neutrophil count and Platelets. Also, anemia was found in 48 patients (19.3%). The study also found a statistically significant correlation between the co-existence of VSD and neutropenia in the patients (P value = 0.000). Conclusion: Although most were mildly neutropenic, there was a significant correlation between neutropenia and Ventricular Septal Defect compared to PDA and ASD groups. Regarding the importance of neutropenia to affect the prognosis of congenital heart defects in infections, it is important to consider further studies on the status of immune system function in these patients.

A Novel Approach to Facilitate an Ideal Surgical Correction of Congenital Lobar Emphysema by Using Neonatal Ultrathin Bronchoscopy-Guided Endo-Bronchial Block.

This is a case report of a child who had acyanotic congenital heart disease - ventricular septal defect (VSD) and a patent ductus arteriosus (PDA) with severe pulmonary arterial hypertension. The child underwent open-heart surgery - VSD closure with PDA ligation - and six months later was re-admitted for congenital lobar emphysema of the right middle lobe. He underwent successful right middle lobectomy of the lung six months after cardiac surgery under a one-lung ventilation technique in which application of fiber-optic bronchoscope made the surgery safer and more suitable.

Emergency Department Presentation and Outcome of Children With Cyanotic Congenital Heart Diseases.

Objective This study aimed to assess the outcome and see the spectrum of presenting symptoms of children with cyanotic congenital heart diseases (CHDs) admitted through the emergency department in Lady Reading Hospital (LRH) in Peshawar, Pakistan. Materials and methods This cross-sectional study included 104 children with cyanotic CHD admitted through the emergency department in the pediatric cardiology unit of LRH from February 2019 to January 2020. Diagnosis of cyanotic CHD was confirmed through two-dimensional echocardiography. Patients were treated according to standard protocols for their presenting symptoms. The data were analyzed using Statistical Package for the Social Sciences (SPSS), version 20.0 (IBM Corp., Armonk, NY) and frequencies were expressed as percentages. Results The study included 65 male cases (62.5%) and 39 female cases (37.5%), and participant ages ranged from 10 days to 15 years (mean, 2.7 ± 3.4 years). Of 104 patients, 70 presented with cyanotic spells (84.5%), 53 with fever (10.7%), 28 with respiratory distress (26.5%), 11 with loose stools (10.5%), 10 with hemiplegia (9.6%), and eight with seizures (7.6%). Pneumonia was a precipitating factor in 13 patients (12.5%), infective endocarditis in 12 patients (11%), gastroenteritis in 11 (11%), brain abscess and cerebrovascular accidents in seven patients each (6% each), meningitis in six patients (6%), and tuberculous pericardial effusion in one patient (<1%). The primary CHD was tetralogy of Fallot (TOF) in 52 patients, tricuspid atresia in 14 patients, pulmonary atresia in 13 patients, double outlet right ventricle in 10 patients, transposition of great arteries (TGA) in seven patients, and total anomalous pulmonary venous return (TAPVR), truncus arteriosus, congenitally corrected TGA, and critical pulmonary stenosis in two patients each. Twenty-six patients received treatment of the acute problem and instructions for follow-up monitoring. Twelve patients died during their hospital stay, and three left against medical advice. Fifteen patients received patent ductus arteriosus stenting, and six received right ventricular outflow tract stenting. One patient received a Blalock-Taussig (BT) shunt stent, and one received a left pulmonary artery stent. Two patients received a balloon pulmonary valvotomy, and one received pericardial effusion drainage. Eleven patients received surgical correction of TOF, 11 received surgical correction for BT shunt, four received surgical correction for brain abscess drainage, and two received TAPVR repair. Conclusion TOF was the most common cyanotic heart disease in our study. Cyanotic spells or increased cyanosis was the most common presenting concern. Cyanotic CHDs present with variable extracardiac signs and symptoms in emergencies. Appropriate assessment, immediate management of the acute problem, and timely intervention or surgical management result in good outcomes.

In vivo assessment of a single adenine mutation in 5'UTR of Endothelin-1 gene in paediatric cases with severe pulmonary hypertension: an observational study.

OBJECTIVE: Endothelin-1 plays an important role in the pathogenesis of severe pulmonary hypertension. The + 139 'A', adenine insertion variant in 5'UTR of edn1 gene has been reported to be associated with increased expression of Endothelin-1 in vitro. The aim of present study was to explore the association of this variant with the circulating levels of Endothelin-1 in vivo using archived DNA and plasma samples from 38 paediatric congenital heart disease (cyanotic and acyanotic) patients with severe pulmonary hypertension. RESULTS: The plasma Endothelin-1 levels were highly varied ranging from 1.63 to75.16 pg/ml. The + 139 'A' insertion variant in 5'UTR of edn1 was seen in 8 out of 38 cases with only one acyanotic sample demonstrating homozygosity of inserted 'A' allele at + 139 site (4A/4A genotype). The plasma Endothelin-1 levels in children with homozygous variant 3A/3A genotype were comparable in cyanotic and acyanotic groups. Lone 4A/4A acyanotic sample had ET-1 levels similar to the median value of ET-1 associated with 3A/3A genotype and was absent in cyanotic group presumably due to deleterious higher ET-1 levels. The discussed observations, limited by the small sample size, are suggestive of homozygous adenine insertion variant posing a risk in cyanotic babies with Severe Pulmonary Hypertension.

Preoperative level of neutrophil-lymphocyte ratio: Comparison between cyanotic and acyanotic congenital heart disease.

INTRODUCTION: Elevated neutrophil-lymphocyte ratio (NLR) has been associated with poorer outcomes in children undergoing congenital heart surgery under cardiopulmonary bypass (CPB). OBJECTIVE: To compare preoperative NLR levels between cyanotic and acyanotic children undergoing surgical repair with CPB. METHODS: We performed a retrospective cohort study in 60-paired children (30 with tetralogy of Fallot [TOF] and 30 with ventricular septal defect [VSD]) between January 2018 and December 2019 matched by age, weight, and gender. Preoperative NLR was measured from the last complete blood count test before the surgery. All of them had negative viral screening. RESULTS: The median age in VSD children was 9.5 months (interquartile range [IQR]: 5-12), weight 7 kg (IQR: 5.5-8.7), 19 (63%) was female, and NLR was 0.45 (IQR: 0.3-0.65). The median age in TOF children was 8.5 months (IQR: 5-12), weight 7.6 kg (IQR: 5.8-8.7), 16 (53%) were female, and NLR was 0.67 (IQR: 0.41-1.1). Demographic parameters did not show any statistically significant difference between groups (p > .05). Children with TOF had higher preoperative NLR compared with VSD patients (p = .004). As lower O2 saturation as higher the NLR (p = .005). CONCLUSION: The preoperative level of NLR was higher in cyanotic congenital heart disease patients.

Effect of acute lower respiratory tract infection on pulmonary artery pressure in children with post-tricuspid left-to-right shunt.

We sought to examine the influence of clinically severe lower respiratory tract infection on pulmonary artery pressure in children having CHD with post-tricuspid left-to-right shunt, as it may have physiological and clinical implications. In a prospective single-centre observational study, 45 children with post-tricuspid left-to-right shunt and clinically severe lower respiratory tract infection were evaluated during the illness and 2 weeks after its resolution. Pulmonary artery systolic pressure was estimated non-invasively using shunt gradient by echocardiography and systolic blood pressure measured non-invasively.Median pulmonary artery systolic pressure during lower respiratory tract infection was only mildly (although statistically significantly) elevated during lower respiratory tract infection [60 (42-74) versus 53 (40-73) mmHg, (p < 0.0001)]. However, clinically significant change in pulmonary artery systolic pressure defined as the increase of >10 mmHg was present in only 9 (20%) patients. In the absence of hypoxia or acidosis, only a small minority (9%, n = 4) showed significant pulmonary artery systolic pressure rise >10 mmHg. In the absence of hypoxia or acidosis, severe lower respiratory tract infection in patients with acyanotic CHD results in only mild elevation of pulmonary artery systolic pressure in most of the patients.

Percutaneous closure of small subpulmonic ventricular septal defect with an ADO I PDA occluder in a child.

Ventricular septal defects (VSDs) comprise the most common congenital heart defect at birth. The chances of spontaneous closure of VSD depend on the size and location of the defect. Subpulmonic location is an unlikely site for the VSD to close spontaneously and known to have complications such as aortic valve prolapse and regurgitation. Percutaneous closure has become the preferred strategy for small-moderate-sized VSDs located in muscular, perimembranous areas. Subpulmonic location poses concerns due to the close proximity to the aortic valve. Herein, we present a case of percutaneous device closure of a subpulmonic VSD using ADO I occluder device.

[Comparison of ED50 of intranasal dexmedetomidine sedation in children with acyanotic congenital heart disease before and after cardiac surgery].

OBJECTIVE: To compare the median effective dose (ED50) of intranasal dexmedetomidine for procedural sedation in uncooperative pediatric patients with acyanotic congenital heart disease before and after cardiac surgery. METHODS: We prospectively recruited 47 children (22 in preoperative group and 25 in postoperative group) who needed sedation for transthoracic echocardiography (TTE). A modified up-and-down sequential study design was employed to determine dexmedetomidine dose for each patient with a starting dose of 2 µg/kg in both groups; dexmedetomidine doses for subsequent subjects were determined according to the responses from the previous subject using the up-and-down method at a 0.25 µg/kg interval. The ED95 was determined using probit regression. The onset time, examination time, wake-up time and adverse effects were measured, and the safety was evaluated in terms of changes in vital signs every 5 min. RESULTS: The ED50 value of intranasal dexmedetomidine for sedation was 1.84 µg/kg (95% CI: 1.68-2.00 µg/kg) in children with congenital heart disease before cardiac surgery, and 3.38 µg/kg (95% CI: 3.21-3.54 µg/kg) after the surgery. No significant difference was found between the two groups in the demographic variables, onset time, examination time, wake-up time, or adverse effects. CONCLUSIONS: In children with acyanotic congenital heart disease, the ED50 of intranasal dexmedetomidine for TTE sedation increases to 3.38 µg/ kg after cardiac surgery from the preoperative value of 1.84 µg/kg.

Incidence and Patterns of Congenital Heart Disease Among Jordanian Infants, a Cohort Study From a University Tertiary Center.

Background: Data is limited about the incidence of congenital heart disease in Jordan. The goal of this study is to determine the incidence and patterns of congenital heart diseases (CHD) among Jordanian infants evaluated at King Abdullah University Hospital. Methods: A retrospective chart review was conducted for all infants who had an echocardiogram evaluation in the 3-years period July 2016-June 2019. All included infants had a 2-dimentional echocardiogram with a Doppler vascular study performed by the same cardiologist. Infants with a structural congenital heart disease were included in the analysis. Results: A total of 1,028 infants were evaluated at the cardiology department during the study period. Eight hundred and sixty-five had an abnormal echo finding. Two hundred and ninety-eighth were diagnosed with CHD. The incidence of CHD was 25 per 1000 live births. Fifty one percent were premature infants. The majority of cases were mild CHD. Patent ductus arteriosus was the most common acyanotic lesion followed by ventricular septal defect and atrial septal defect with a prevalence of 44, 25, and 25%, respectively. Cyanotic CHD constituted 6% of all CHD. Tetralogy of Fallott was the most common cyanotic CHD. The main indication for referral was hearing a heart murmur during physical examination. Conclusion: Although the incidence of CHD in our cohort was relatively high, the majority of cases were acyanotic mild CHD with favorable prognosis. A wider population-based study is needed to evaluate the incidence and better understand the patterns and distribution of CHD at a national level.

Clinical Diagnostic Approach to Congenital Acyanotic Congenital Heart Disease in Infants and Children.

Congenital heart diseases have varied presentations depending on the age of presentation. Regression of neonatal pulmonary hypertension and the timing of establishment of left to right shunt determines the onset of symptoms. Pre-tricuspid shunts generally remain asymptomatic during the childhood while large post-tricuspid shunts present with heart failure in late neonatal or early infancy period. Admixture lesions have pathophysiology similar to large post tricuspid shunts with additional small right to left shunt causing mild systemic desaturation. Murmurs are prominent in valvular heart diseases. Careful clinical assessment of features of high pulmonary blood flow, presence of absence of systemic desaturation, status of second heart sound and murmur would help to arrive at a reasonable bedside diagnosis.

Timing of Interventions in Infants and Children with Congenital Heart Defects.

Congenital heart defects (CHD) are the most common form of birth anomalies. About one-fifth of these are critical requiring very early intervention, the classical examples being transposition of great arteries or obstructive total anomalous pulmonary venous connection. On the other hand, relatively milder and simpler lesions, such as small ventricular septal defects or mild pulmonary stenosis, may either not need intervention at all or intervened as and when deemed necessary. Apart from the cardiovascular effects, some CHDs can significantly affect the physical growth and neurodevelopment of the child. Each type of CHD has unique hemodynamic effects and the intervention is, by and large, timed based on the severity and natural history of each cardiac lesion. Some lesions have a "limited" time window beyond which they may become unsuitable for any intervention. Hence it is critical to intervene at the appropriate time so as to prevent the untoward effects of CHDs and at the same time to avoid unnecessary interventions.

Comparison of antioxidant reserve capacity of children with acyanotic & cyanotic congenital heart disease.

BACKGROUND & OBJECTIVES: Oxidative stress can cause many diseases and increases the risk of post-operative complications in children with congenital heart disease. For these reasons, this study was aimed to investigate the differences between cyanotic and acyanotic paediatric patients who underwent heart surgery with markers of oxidative stress. METHODS: Eighty five patients were included in the study. The samples taken before the surgery and within the first 24 h after the surgery were evaluated for haemoglobin (Hb), leukocytes, uric acid, glutathione (GSH), malondialdehyde and total antioxidant capacity. Cyanotic, acyanotic, hyperoxygenated, normo-oxygenated, cardiac surgery with or without cardiopulmonary bypass (CPB) comparisons were made. RESULTS: Positive correlation was found between age and pre-operative total antioxidant status values. Cyanotic and acyanotic patients did not have different antioxidant reserve capacities preoperatively. Although pre-operative thiobarbituric acid reactive substances (TBARS) levels were significantly lower in cyanotic patients, post-operative levels were higher. TBARS levels increased and GSH levels reduced postoperatively. The level of oxygenation did not cause a significant difference on markers of oxidative stress. The duration of CPB did not have negative effects on oxidative stress. INTERPRETATION & CONCLUSIONS: Cyanotic and younger patients were found to be more vulnerable to oxidative stress. The increased levels of TBARS and the decreased levels of GSH could be the indicators of oxidative damage depending on many factors such as surgery, CPB, ischaemia/reperfusion, inflammation, iron overload and oxygenation. The level of oxygenation does not cause a noticeable difference in oxidative stress. CPB causes oxidative stress, but if it is conducted appropriately, the duration of CPB does not cause a significant negative impact on oxidative stress.

Management of Congenital Heart Disease: State of the Art; Part I-ACYANOTIC Heart Defects.

Since the description of surgery for patent ductus arteriosus in late 1930s, an innumerable number of advances have taken place in the management of congenital heart defects (CHDs). In this review the current status of treatment of seven of the most common acyanotic CHDs was reviewed. The discussion included indications for, and timing of, intervention and methods of intervention. The indications are, by and large, determined by the severity of the lesion. Pressure gradients in obstructive lesions and the magnitude of the shunt in left-to-right shunt lesions are used to assess the severity of the lesion. The timing of intervention is different for each lesion and largely dependent upon when the criteria for indications for intervention were met. Appropriate medical management is necessary in most patients. Trans-catheter methods are preferable in some defects while surgery is a better option in some other defects. The currently available medical, trans-catheter, and surgical methods to treat acyanotic CHD are feasible, safe, and effective.
