LVNC is a relatively new clinical entity, with a significant increase in awareness and diagnosis in recent years. Currently the aetiology and pathogenesis of LVNC remains uncertain, alongside prevalence, however the diagnosis of LVNC appears to be increasing with improving imaging techniques. For educational purposes involving a rare clinical condition, we present the case of a 52 year old gentleman who was diagnosed with LV non compaction via ECHO and CMR. Interestingly it was noted two of his children had congenital heart disease, one daughter had Tetralogy of Fallot, and a second daughter had both an ASD and VSD. Challenges facing LVNC involve difficulty of diagnosis with no gold standard yet available, uncertainty of benefit with standard disease modifying therapies for HF-REF, and apparent increased risk of arrhythmias suggesting early ICD placement may be warranted for patients.

ABSTRACT Infants and children with congenital heart disease exhibit a range of delays in weight gain and growth. In some instances, the delay can be relatively mild, whereas in other cases, cause the failure to thrive. OBJECTIVES To determine the nutritional status and associated factors of pediatric patients with congenital heart disease. MATERIAL AND METHODS A cross sectional analytical study was done over a period of 6months (Feb to Jul 2020). A total of 228 subjects with congenital heart disease that come to the cardiac center during the study period where included until the calculated sample size was attained. Data was collected from patient card and care givers of the children included in the study after obtaining their informed consent using data inquiry sheet. RESULTS A total of 228 children from age 3month to 17yrs. Most of the subjects had acyanotic heart disease accounting for 87.7%. The overall prevalence of wasting, underweight and stunting were 41.3%, 49.1% and 43% respectively. Among this children with congenital heart disease those with PAH were found more likely have wasting compared to those without PAH with an odds of 1.9 (95% CI: 1.0-3.4) and also greater chance of being stunted with an odds of 1.9 (95% CI: 1.0-3.4). children above 5years of age were 2.3 times more likely to be underweight. CONCLUSION Malnutrition is a major problem of patients with CHD. Pulmonary hypertension and older age are associated with increased risk of undernutrition. KEYWORDS: Acyanotic, cyanotic, Pulmonary hypertension, underweight, wasting and stunting.

Background: Obesity can adversely affect most organ systems and increases the risk of comorbidities likely to be of consequence for patients with complex adult congenital heart disease (ACHD). Conversely, several studies have demonstrated that low body mass index (BMI) is a risk factor for heart failure and adverse outcomes after cardiac surgery. However, there are currently no data regarding the impact of BMI in ACHD. Methods: We examined the charts of 87 randomly selected, complex ACHD patients whose first visit to our institution was at 18-22 years old. Patients were categorized according to BMI at initial visit: underweight (BMI < 18.5 kg/m 2 ), normal (BMI 18.5 - 24.9 kg/m 2 ), overweight/obese (BMI ≥ 25 kg/m 2 ). Events occurring during follow-up were recorded. Data was censured on 1/1/2014. Cardiac events were defined as a composite of cardiac death, heart transplantation or admission for heart failure. Results: The cohort included patients with the following diagnoses: tetralogy of Fallot n=31, Mustard n=28, Fontan n=17, ccTGA n=9 and aortic coarctation n=2. The median (IQR) duration of follow-up was 8.7 (4.2 - 1.8) years. See table for distribution and outcomes by BMI category. Cardiac events occurred in 17/87 patients. After adjustment for age, sex, and underlying disease, the underweight group had increased risk of cardiac events (HR=12.9, 95% CI: 2.8-61.5, p < 0.05). Kaplan-Meier curves demonstrate the poorer prognosis of underweight patients (Figure). Conclusions: Underweight was associated with increased risk of late cardiac events in ACHD patients. We were unable to demonstrate significant overweight/obesity impact.

Abstract Background Causes, epidemiology and microbiology of infective endocarditis (IE) have evolved in recent decades. Although novel tools for the diagnosis and therapeutic strategies have emerged, mortality and morbidity remain high. These trends may particularly concern the growing population of adults with congenital heart disease (CHD) who are at increased risk for IE. Purpose We aimed to characterize IE in CHD patients and describe management and outcome in this setting. We also sought to determine the risk factors associated with in-hospital death in CHD patients. Methods From January 2000 to June 2018, 666 consecutive episodes of IE in adults were recorded in our center. Among them, 143 concerned CHD, including 5 implantable cardiac electronic devices-lead infections, all managed by an IE team including CHD specialists. Cases were classified according to modified Duke criteria. Results CHD patients were significantly younger (37 years IQR [26–52]), with a more common history of cardiac reoperations (numbers of sternotomies≥2 in 35.7%) and infective endocarditis (19.7%, p<0.01) compared to non-CHD patients. There were more infections of valve-containing prosthetics (44% vs. 30%, p<0.04), and the right heart side (41.5%, p<0.01) in CHD patients. Forty-nine percent of them had a simple CHD, 12.7% a moderate, and 36.4% a complex. A predisposing event could be identified in only 34% of cases. Oral streptococci/Streptococci bovis and Staphylococcus aureus were the most frequently microorganisms isolated (32.4% and 20.4%, respectively). Surgery was performed in 90 episodes (62%), and was selected in emergency (<24h) in 61% (figure 1). In-hospital mortality was 12.7% and was directly related to IE in 10/18 cases. CHD patients had a significant lower risk of death compared to non-CHD patients (OR=0.47, p=0.026, p<0.01), even after adjustment for age, and the infected heart side. On multivariate analysis the complexity of CHD (if simple CHD: OR=0.07 IQR [0.01 to 0.44], p<0.01) and the white blood cell count (OR=1.18 IQR [1.04 to 1.33], p=0.01) were the strongest predictive factors of in-hospital death in the CHD group. Conclusions Mortality associated with IE in CHD patients is lower than in acquired heart disease. The multidisciplinary approach by IE team and CHD specialists may have improved management and outcome in this setting. However, risk for death remains high in complex lesions. Larger prospective studies on IE in adults with CHD are needed to develop guidelines in these complex patients.

Background: Dexmedetomidine has been suggested as an arrhythmia prophylactic agent after surgery for congenital heart disease due to its heart rate lowering effect, though studies are conflicting. We sought to study the effect of dexmedetomidine in infants that are at highest risk for arrhythmias. Methods: Retrospective cohort study of infants less than six months of age undergoing cardiopulmonary bypass for congenital heart disease. The arrhythmia incidence in the first 48 hours after surgery in infants receiving dexmedetomidine for sedation was compared to those that did not receive dexmedetomidine. Results: A total of 309 patients were included, 206 patients who did not receive dexmedetomidine and 103 patients who did. The incidence of tachyarrhythmias was similar between the non-DEX group and the DEX group (19% vs 15%, P = .34). When adjusted for baseline differences, the non-DEX group did not have an increased risk of postoperative tachyarrhythmias (odds ratio [OR]: 1.4, 95% confidence interval [CI]: 0.5-3.8). The non-DEX group had an increased need for treatment for arrhythmias (18% vs 8%, P = .012). The three lesions with baseline higher risk for arrhythmias (tetralogy of Fallot, transposition of the great arteries, and complete atrioventricular canal) had an increased incidence of tachyarrhythmias in the non-DEX group (34% vs 6%, P = .027). This risk was not significant in multivariate analysis (OR: 2.5, 95% CI: 0.4-15.5). Conclusions: High-risk infants had decreased incidence of tachyarrhythmias when receiving dexmedetomidine, though this was not significant after accounting for baseline differences between groups.

Abstract Background Young children and those with chronic medical conditions are at risk for complications of influenza including cardiopulmonary compromise. Here we aim to examine risks of mortality, clinical complications in children with congenital heart disease (CHD) hospitalized for influenza. Methods We analyzed data from in-hospital pediatric patients from 2003, 2006, 2009, 2012 and 2016 using the nationally representative Kids Inpatient Database (KID). We included children 1 year and older and used weighted data to compare the incidence of in-hospital mortality and rates of complications such as respiratory failure, acute kidney injury, need for mechanical ventilation, arrhythmias and myocarditis. Results Data from the KID estimated 125,470 children who were admitted with a diagnosis of influenza infection. Out of those, 2174(1.73%) patients had discharge diagnosis of CHD. Children with CHD who required hospitalization for influenza had higher in-hospital mortality (2.0% vs 0.5%), with an adjusted OR (aOR) of 2.8 (95% CI: 1.7–4.5). Additionally, acute respiratory failure and acute kidney failure were more likely among patients with CHD, with aOR of 1.8 (95% CI: 1.5–2.2) and aOR of 2.2 (95% CI: 1.5–3.1), respectively. Similarly, the rate of mechanical ventilatory support was higher in patients with CHD compared to those without, 14.1% vs 5.6%, aOR of 1.9 (95% CI: 1.6–2.3). Median length of hospital stay in children with CHD was longer than those without CHD [4 (IQR: 2–8) days vs. 2 (IQR: 2–4) days]. Outcomes were similar between those with severe vs non-severe CHD. Conclusions Children with CHD who require hospital admission for influenza are at significantly increased risk for in-hospital mortality, morbidities, emphasizing the need to reinforce preventative measures (e.g. vaccination, personal hygiene) in this particularly vulnerable population.

Abstract BACKGROUND Evidence is emerging suggesting associations between environmental pollutants, socio-economic status (SES) and congenital heart disease (CHD); however, it is still inconclusive. Furthermore, it has been documented in environmental injustice studies that people with low socio-economic status are disproportionately vulnerable to environmental hazards and therefore are victims of a double jeopardy. OBJECTIVES We sought to explore the effect of exposure to groups of developmental toxicants (DTs) and SES on CHD development in urban and rural Alberta. DESIGN/METHODS We identified 2,413 CHD cases and postal codes (PC) from echocardiographic databases (2003–2010). We used previously defined groups of DTs comprised of: 1- organics and gases, 2-organics and 3-heavy metals. Exposure was assigned to each PC as the sum of the product of multiplying amounts of DTs (tonnes) emitted from any industrial facility within 10 km radius during the whole study period, by the inverse distance from the facility to the centroid of the PC. Exposures were categorized into deciles from 1(lowest) to 10 (highest) for group 1 DTs and tertiles (1=lowest to 3 =highest), for groups 2 and 3 DTs and the SES index. Poisson regression models were used to calculate risk ratios and 95% CI, adjusted for SES index or DTs and traffic-related surrogates (NO2, PM2.5). RESULTS Adjusted Effect of DT Exposure: Group 1 DT showed increased risk in urban and rural regions in the 10th decile of exposure, aRR=1.85(1.5, 2.3) and 2.67(1.04, 6.8, respectively). Group 2 DT risk was increased only in urban 3rd tertile, RR=1.45(1.3, 1.6). Group 3 DTs were associated with an increased risk in urban and rural regions in the 3rd tertile of exposure [aRR=1.16(1.04, 1.3), and 2.8(1.14, 7.1, respectively)]. Adjusted Effect of SES: SES was independently associated with an increased risk of CHD in urban lowest tertile, [aRR=1.13(1.0, 1.3)] and rural lowest and middle SES tertile, [aRR=2.9(1.9, 4.8) and 1.6(1.1, 2.6), respectively]. CONCLUSION High exposures to groups of DTs and SES were independently associated with an increased risk of CHD in urban and rural Alberta. This suggests that neighborhood SES in Alberta does not impose a disproportional exposure to DTs. Furthermore, SES had a greater impact in rural compared to urban regions. We would like to explore for interactions between the SES and DT exposures and to determine if there is environmental injustice in Alberta.

AbstractPregnancy-associated diseases of the cardiovascular system occur in up to 10% of all pregnancies and the incidence is increasing. Besides congenital heart disease or pre-existing cardiomyopathy in the mother, the clinical focus has moved especially to peripartum cardiomyopathy (PPCM) because of the conditionʼs dramatic clinical course and the identification of the underlying mechanisms. This review article concentrates therefore on PPCM, which occurs either in the last month of pregnancy or in the first 6 months following delivery in women with previously healthy hearts. The global incidence is estimated today at roughly 1 : 1000 pregnancies. The condition is heterogeneous, ranging from mild disease to severe acute heart failure with cardiogenic shock and sudden cardiac death of the mother. Important risk factors are pregnancy-associated hypertensive complications, multiple pregnancy and greater maternal age. The pathogenesis comprises cleavage, induced by increased oxidative stress, of the lactation hormone prolactin into a toxic hormone fragment that damages blood vessels, known as the 16-kDalton protein fragment. The lactation-blocking drug bromocriptine prevents prolactin release and promotes healing of PPCM in combination with pharmacological heart failure therapy; it appears to prevent recurrence in subsequent pregnancies. Uncomplicated pregnancy is possible in most patients with congenital heart disease. The foetal complications include an increased abortion rate, prematurity and smallness for gestational age, as well as an increased risk of cardiac malformations. The maternal risk comprises mainly arrhythmias, progressive heart failure and thrombembolic complications, with the risk of vessel dissection with a low mortality risk of < 1% in the case of aortopathies. Individual risk assessment and corresponding close monitoring of the pregnancy are required.

Abstract Background The aim of this study was to investigate an association between birth defects and exposure to sulfur dioxide (SO2), nitrogen dioxide (NO2) and particles ≤10 μm in an aerodynamic diameter (PM10) during early pregnancy in Xi’an, China. Methods Birth defect data were from the Birth Defects Monitoring System of Xi’an, and data on ambient air pollutants during 2010–15 were from the Xi’an Environmental Protection Bureau. A generalized additive model (GAM) was used to investigate the relationship between birth defects and ambient air pollutants. Results Among the 8865 cases with birth defects analyzed, the overall incidence of birth defects was 117.33 per 10 000 infants. Ambient air pollutant exposure during the first trimester increased the risk of birth defects by 10.3% per 10 μg/m3 increment of NO2 and 3.4% per 10 μg/m3 increment of PM10. No significant association was found between birth defects and SO2. Moreover, NO2 increased risk of neural tube defects, congenital heart disease, congenital polydactyly, cleft palate, digestive system abnormalities and gastroschisis, and PM10 was associated with congenital heart disease and cleft lip with or without cleft palate. Conclusions Chinese women should avoid exposure to high levels of NO2 and PM10 during the first 3 months of pregnancy.
