Shorter time since inflammatory bowel disease diagnosis in children is associated with lower mental health in parents.

AIM: This study assessed the mental health of parents of children with inflammatory bowel disease (IBD), compared their mental health with age-matched and gender-matched references and examined parental and child predictors for mental health problems. METHODS: A total of 125 mothers and 106 fathers of 125 children with active and inactive IBD from the Swiss IBD multicentre cohort study were included. Parental mental health was assessed by the Symptom Checklist 27 and child behaviour problems by the Strengths and Difficulties Questionnaire. Child medical data were extracted from hospital records. RESULTS: While the mothers reported lower mental health, the fathers' mental health was similar, or even better, than in age-matched and gender-matched community controls. In both parents, shorter time since the child's diagnosis was associated with poorer mental health. In addition, the presence of their own IBD diagnosis and child behaviour problems predicted maternal mental health problems. CONCLUSIONS: Parents of children with IBD may need professional support when their child is diagnosed, to mitigate distress. This, in turn, may help the child to adjust better to IBD. Particular attention should be paid to mothers who have their own IBD diagnosis and whose children display behaviour problems.

Association of major and minor ECG abnormalities with coronary heart disease events.

CONTEXT: In populations of older adults, prediction of coronary heart disease (CHD) events through traditional risk factors is less accurate than in middle-aged adults. Electrocardiographic (ECG) abnormalities are common in older adults and might be of value for CHD prediction. OBJECTIVE: To determine whether baseline ECG abnormalities or development of new and persistent ECG abnormalities are associated with increased CHD events. DESIGN, SETTING, AND PARTICIPANTS: A population-based study of 2192 white and black older adults aged 70 to 79 years from the Health, Aging, and Body Composition Study (Health ABC Study) without known cardiovascular disease. Adjudicated CHD events were collected over 8 years between 1997-1998 and 2006-2007. Baseline and 4-year ECG abnormalities were classified according to the Minnesota Code as major and minor. Using Cox proportional hazards regression models, the addition of ECG abnormalities to traditional risk factors were examined to predict CHD events. MAIN OUTCOME MEASURE: Adjudicated CHD events (acute myocardial infarction [MI], CHD death, and hospitalization for angina or coronary revascularization). RESULTS: At baseline, 276 participants (13%) had minor and 506 (23%) had major ECG abnormalities. During follow-up, 351 participants had CHD events (96 CHD deaths, 101 acute MIs, and 154 hospitalizations for angina or coronary revascularizations). Both baseline minor and major ECG abnormalities were associated with an increased risk of CHD after adjustment for traditional risk factors (17.2 per 1000 person-years among those with no abnormalities; 29.3 per 1000 person-years; hazard ratio [HR], 1.35; 95% CI, 1.02-1.81; for minor abnormalities; and 31.6 per 1000 person-years; HR, 1.51; 95% CI, 1.20-1.90; for major abnormalities). When ECG abnormalities were added to a model containing traditional risk factors alone, 13.6% of intermediate-risk participants with both major and minor ECG abnormalities were correctly reclassified (overall net reclassification improvement [NRI], 7.4%; 95% CI, 3.1%-19.0%; integrated discrimination improvement, 0.99%; 95% CI, 0.32%-2.15%). After 4 years, 208 participants had new and 416 had persistent abnormalities. Both new and persistent ECG abnormalities were associated with an increased risk of subsequent CHD events (HR, 2.01; 95% CI, 1.33-3.02; and HR, 1.66; 95% CI, 1.18-2.34; respectively). When added to the Framingham Risk Score, the NRI was not significant (5.7%; 95% CI, -0.4% to 11.8%). CONCLUSIONS: Major and minor ECG abnormalities among older adults were associated with an increased risk of CHD events. Depending on the model, adding ECG abnormalities was associated with improved risk prediction beyond traditional risk factors.

Does CRP Play a Causal Role in the Development of Coronary Heart Disease: Results of a Mendelian Randomisation Experiment Involving 128,935 People

Background: C-reactive protein (CRP) is associated with risk of coronary heart disease (CHD). Whether CRP is causally associated with CHD or merely a marker of underlying atherosclerosis is uncertain. Methods: We used a Mendelian randomisation design to investigate the causal relationship of CRP with CHD. We identified three genetic variants in the CRP locus (rs7553007, rs1130864 and rs1205) which influence CRP levels. We tested the three SNPs for association with CHD amongst 28,112 CHD cases and 100,823 controls. We then compared the observed relationship between the SNPs and CHD, with that predicted from the association of SNPs with CRP levels, and of CRP levels with CHD. Results: SNPs in the CRP locus were not associated with CHD: rs7553007, OR 0.98 (95% CI, 0.94-1.01); rs1130864, OR 1.00 (95% CI, 0.86-1.15); rs1205, OR 1.03 (95% CI, 0.99-1.07); combined OR for all three SNPs, 1.00 (95% CI, 0.97-1.02), per 20% lower CRP (figure). In contrast, the predicted OR for CHD from a 20% lower CRP level is 0.94 (95% CI, 0.94- 0.95), based on meta-analysis of observational studies. Conclusions: Though CRP variants are associated with CRP levels, and CRP levels with risk of CHD, we observed that CRP variants are not associated with CHD risk. Our Mendelian randomisation experiment strongly argues against a causal association of CRP with CHD.

A simple score for estimating ischemic heart disease in patients with non-traumatic chest pain in primary care

Background: Modelling epidemiological knowledge in validated clinical scores is a practical mean of integrating EBM to usual care. Existing scores about cardiovascular disease have been largely developed in emergency settings, but few in primary care. Such a toll is needed for general practitioners (GP) to evaluate the probability of ischemic heart disease (IHD) in patients with non-traumatic chest pain. Objective: To develop a predictive model to use as a clinical score for detecting IHD in patients with non-traumatic chest-pain in primary care. Methods: A post-hoc secondary analysis on data from an observational study including 672 patients with chest pain of which 85 had IHD diagnosed by their GP during the year following their inclusion. Best subset method was used to select 8 predictive variables from univariate analysis and fitted in a multivariate logistic regression model to define the score. Reliability of the model was assessed using split-group method. Results: Significant predictors were: age (0-3 points), gender (1 point), having at least one cardiovascular risks factor (hypertension, dyslipidemia, diabetes, smoking, family history of CVD; 3 points), personal history of cardiovascular disease (1 point), duration of chest pain from 1 to 60 minutes (2 points), substernal chest pain (1 point), pain increasing with exertion (1 point) and absence of tenderness at palpation (1 point). Area under the ROC curve for the score was of 0.95 (IC95% 0.93; 0.97). Patients were categorised in three groups, low risk of IHD (score under 6; n = 360), moderate risk of IHD (score from 6 to 8; n = 187) and high risk of IHD (score from 9-13; n = 125). Prevalence of IHD in each group was respectively of 0%, 6.7%, 58.5%. Reliability of the model seems satisfactory as the model developed from the derivation set predicted perfectly (p = 0.948) the number of patients in each group in the validation set. Conclusion: This clinical score based only on history and physical exams can be an important tool in the practice of the general physician for the prediction of ischemic heart disease in patients complaining of chest pain. The score below 6 points (in more than half of our population) can avoid demanding complementary exams for selected patients (ECG, laboratory tests) because of the very low risk of IHD. Score above 6 points needs investigation to detect or rule out IHD. Further external validation is required in ambulatory settings.

Subclinical hyperthyroidism and the risk of coronary heart disease and mortality

Contexte L'hyperthyroïdie infra-clinique est une perturbation de la fonction thyroïdienne, définie par une thyrotropine (TSH) basse et des taux normaux de thyroxine libre (T4L) et triiodothyronine (T3). Cette dysfonction affecte de 1% à 5% des adultes de plus de 65 ans, surtout les femmes, et pourrait être associée avec les maladies cardiovasculaires, la fibrillation auriculaire et l'insuffisance cardiaque. Toutefois, les conclusions des différentes études de cohortes sont contradictoires, avec des limites méthodologiques empêchant leur comparaison de manière formelle. L'objet du travail de thèse était d'estimer le risque de mortalité de toute cause, le risque de mortalité de cause cardiovasculaire, le risque d'événements cardiovasculaires et le risque de fibrillation auriculaire associés à l'hyperthyroïdie infra-clinique dans toutes les grandes études de cohorte prospectives disponibles à ce jour. Méthode et Résultats Les données individuelles de 52'674 participants provenant de 10 études de cohorte prospectives des Etats-Unis, d'Europe, du Brésil et d'Australie ont été analysées pour évaluer les risques à long-terme de l'hyperthyroïdie infra-clinique. L'euthyroïdie était définie par une TSH entre 0.45 et 4.49 mUI/l et l'hyperthyroïdie infra-clinique par une TSH inférieure à 0.45 mUI/l avec un taux normal de T4L, après exclusion des participants prenant des médicaments pouvant perturber la thyroïde. Sur les 52'674 participants, 2188 (4.2%) avaient une hyperthyroïdie infra-clinique. Pendant un suivi de plus de 8 ans, 8527 participants sont décédés (dont 1896 de cause cardiovasculaire), 3653 sur 22'437 ont eu un événement cardiovasculaire et 785 sur 8711 ont développé une fibrillation auriculaire. Dans des analyses ajustées pour l'âge et le sexe, l'hyperthyroïdie infra-clinique était associée à une hausse de la mortalité de toute cause (hazard ratio [HR] 1.24, intervalle de confiance à 95% [IC] 1.06-1.46), de la mortalité cardiovasculaire (HR 1.29, IC 1.02-1.62), des événements cardiovasculaires (HR 1.21, IC 0.99- 1.46) ainsi qu'une hausse de l'incidence de fibrillation auriculaire (HR 1.68, IC 1.16-2.43). Les risques ne différaient pas significativement dans les analyses stratifiées selon l'âge, le sexe ou la présence de maladies cardiovasculaires préexistantes, et étaient similaires après ajustement multiple pour les facteurs de risque cardiovasculaire. Le risque de mortalité cardiovasculaire et de fibrillation auriculaire était plus élevé avec une TSH très basse (< 0.10 Ul/I) comparé à une TSH modérément abaissée (0.10-0.44 mUI/l, valeurs ρ for trend < 0.03). Conclusions et perspectives L'hyperthyroïdie infra-clinique est associée à un risque augmenté de mortalité de toute cause, de cause cardiovasculaire et de fibrillation auriculaire, avec un risque plus élevé quand la TSH est inférieure à 0.10 mUI/l. Ces résultats sont cohérents avec les dernières recommandations internationales conseillant de considérer un traitement de l'hyperthyroïdie infra-clinique pour les adultes de plus de 65 ans ou les patients avec maladie cardiaque, en particulier si la TSH est inférieure à 0.10 mUI/l. Toutefois, des études cliniques randomisées sont encore nécessaires pour prouver l'efficacité du traitement et déterminer si l'on devrait dépister les problèmes de thyroïde dans la population générale.

Randomized trial of a computerized coronary heart disease risk assessment tool in HIV-infected patients receiving combination antiretroviral therapy.

BACKGROUND: Exposure to combination antiretroviral therapy (cART) can lead to important metabolic changes and increased risk of coronary heart disease (CHD). Computerized clinical decision support systems have been advocated to improve the management of patients at risk for CHD but it is unclear whether such systems reduce patients' risk for CHD. METHODS: We conducted a cluster trial within the Swiss HIV Cohort Study (SHCS) of HIV-infected patients, aged 18 years or older, not pregnant and receiving cART for >3 months. We randomized 165 physicians to either guidelines for CHD risk factor management alone or guidelines plus CHD risk profiles. Risk profiles included the Framingham risk score, CHD drug prescriptions and CHD events based on biannual assessments, and were continuously updated by the SHCS data centre and integrated into patient charts by study nurses. Outcome measures were total cholesterol, systolic and diastolic blood pressure and Framingham risk score. RESULTS: A total of 3,266 patients (80% of those eligible) had a final assessment of the primary outcome at least 12 months after the start of the trial. Mean (95% confidence interval) patient differences where physicians received CHD risk profiles and guidelines, rather than guidelines alone, were total cholesterol -0.02 mmol/l (-0.09-0.06), systolic blood pressure -0.4 mmHg (-1.6-0.8), diastolic blood pressure -0.4 mmHg (-1.5-0.7) and Framingham 10-year risk score -0.2% (-0.5-0.1). CONCLUSIONS: Systemic computerized routine provision of CHD risk profiles in addition to guidelines does not significantly improve risk factors for CHD in patients on cART.

Parenteral anticoagulants in heart disease: Current status and perspectives (Section II). Position Paper of the ESC Working Group on Thrombosis - Task Force on Anticoagulants in Heart Disease.

Anticoagulants are a mainstay of cardiovascular therapy, and parenteral anticoagulants have widespread use in cardiology, especially in acute situations. Parenteral anticoagulants include unfractionated heparin, low-molecular-weight heparins, the synthetic pentasaccharides fondaparinux, idraparinux and idrabiotaparinux, and parenteral direct thrombin inhibitors. The several shortcomings of unfractionated heparin and of low-molecular-weight heparins have prompted the development of the other newer agents. Here we review the mechanisms of action, pharmacological properties and side effects of parenteral anticoagulants used in the management of coronary heart disease treated with or without percutaneous coronary interventions, cardioversion for atrial fibrillation, and prosthetic heart valves and valve repair. Using an evidence-based approach, we describe the results of completed clinical trials, highlight ongoing research with currently available agents, and recommend therapeutic options for specific heart diseases.

Subclinical hypothyroidism and the risk of coronary heart disease: a meta-analysis.

PURPOSE: Subclinical hypothyroidism has been associated with elevated cholesterol and increased risk for atherosclerosis, but data on the risk of coronary heart disease (CHD) are conflicting. We performed a systematic review to determine whether subclinical hypothyroidism is associated with CHD in adults. METHODS: We searched MEDLINE from 1966 to April 2005, and the bibliographies of key articles to identify studies that provided risk estimates for CHD or cardiovascular mortality associated with subclinical hypothyroidism. Two authors independently reviewed each potential study for eligibility, assessed methodologic quality, and extracted the data. RESULTS: We identified 14 observational studies that met eligibility criteria. Subclinical hypothyroidism increased the risk of CHD (summary odds ratio [OR]: 1.65, 95% confidence interval [CI], 1.28-2.12). The summary OR for CHD was 1.81 (CI, 1.38-2.39) in 9 studies adjusted or matched for demographic characteristics, and 2.38 (CI, 1.53-3.69) after pooling the studies that adjusted for most cardiovascular risk factors. Sensitivity analyses including only population-based studies and those with formal outcome adjudication procedures yielded similar results. Subgroup analyses by type of study design showed a similar trend, but lower risk, in the 5 prospective cohort studies (OR 1.42, CI, 0.91-2.21), compared with the case-control and cross-sectional studies (OR 1.72, CI, 1.25-2.38). CONCLUSION: Our systematic review indicates that subclinical hypothyroidism is associated with an increased risk of CHD. Clinical trials are needed to assess whether thyroxine replacement reduces the risk of CHD in subjects with subclinical hypothyroidism.

Meta-analysis: subclinical thyroid dysfunction and the risk for coronary heart disease and mortality

BACKGROUND: Data on the association between subclinical thyroid dysfunction and coronary heart disease (CHD) and mortality are conflicting. PURPOSE: To summarize prospective evidence about the relationship between subclinical thyroid dysfunction and CHD and mortality. DATA SOURCES: MEDLINE (1950 to January 2008) without language restrictions and reference lists of retrieved articles were searched. STUDY SELECTION: Two reviewers screened and selected cohort studies that measured thyroid function and then followed persons prospectively to assess CHD or mortality. DATA EXTRACTION: By using a standardized protocol and forms, 2 reviewers independently abstracted and assessed studies. DATA SYNTHESIS: Ten of 12 identified studies involved population-based cohorts that included 14 449 participants. All 10 population-based cohort studies examined risks associated with subclinical hypothyroidism (2134 CHD events and 2822 deaths), whereas only 5 examined risks associated with subclinical hyperthyroidism (1392 CHD events and 1993 deaths). In a random-effects model, the relative risk (RR) for subclinical hypothyroidism for CHD was 1.20 (95% CI, 0.97 to 1.49; P for heterogeneity = 0.14; I(2 )= 33.4%). Risk estimates were lower when higher-quality studies were pooled (RR, 1.02 to 1.08) and were higher among participants younger than 65 years (RR, 1.51 [CI, 1.09 to 2.09] for studies with mean participant age <65 years and 1.05 [CI, 0.90 to 1.22] for studies with mean participant age > or =65 years). The RR was 1.18 (CI, 0.98 to 1.42) for cardiovascular mortality and 1.12 (CI, 0.99 to 1.26) for total mortality. For subclinical hyperthyroidism, the RR was 1.21 (CI, 0.88 to 1.68) for CHD, 1.19 (CI, 0.81 to 1.76) for cardiovascular mortality, and 1.12 (CI, 0.89 to 1.42) for total mortality (P for heterogeneity >0.50; I(2 )= 0% for all studies). LIMITATIONS: Individual studies adjusted for different potential confounders, and 1 study provided only unadjusted data. Publication bias or selective reporting of outcomes could not be excluded. CONCLUSION: Subclinical hypothyroidism and hyperthyroidism may be associated with a modest increased risk for CHD and mortality, with lower risk estimates when pooling higher-quality studies and larger CIs for subclinical hyperthyroidism

Levosimendan as rescue therapy after surgery for congenital heart disease

Objectives: Levosimendan, a calcium-sensitizing agent has been reported as useful for the management of patients with low cardiac output state. We report here our experience, safety and efficacy of use of levosimendan as rescue therapy after surgery for congenital heart disease. Methods: Retrospective cohort study on patients necessitating levosimendan therapy for post operative low cardiac output or severe post operative systolic and diastolic dysfunction. Twelve patients with a mean age of 2.1 years (range 7 days - 14 years old) received levosimendan. Type of surgery: 3 arterial switch, 3 correction of complete abnormal pulmonary venous return, 3 closure of VSD and correction of aortic coarctation, 3 Tetralogy of Fallot, one correction of truncus arteriosus and one palliation for single ventricle. The mean time of ECC was 203 +/- 81min. Ten patients received levosimendan for low cardiac output not responding to conventional therapy in these cases (milrinone, dopamine and noradrenaline) in the first 6 hours following entry in the ICU and 3 patients received levosimendan 3-4 days after surgery for severe systolic and diastolic dysfunction. Levosimendan was given as a drip for 24-48 hours at the dose of 0.1-0.2 mcg/ kg/min, without loading dose. Results: Significant changes were noted on mean plasmatic lactate (3.3 +/- 1.7mmole/L vs 1.8 +/-0.6mmole/L, p+0.01), mean central venous saturation (55 +/- 11% vs 68 +/- 10%, p+0.01) and mean arterio-venous difference in CO2 (9.6 +/- 4.9mmHg vs 6.7 +/- 2.1mmHg, p+0.05) for values before and at the end of levosimendan administration. There was no significant changes on heart rate, systolic pressure or central venous pressure. No adverse effect was observed. Conclusion: Levosimendan, used as rescue therapy after surgery for congenital heart disease, is safe and improves cardiac output as demonstrated with improvement of parameters commonly used clinically.

Meta-analysis : subclinical thyroid dysfunction and the risk for coronary heart disease and mortality

Rapport de synthèse : Description : ce travail de thèse évalue de façon systématique les études sur l'association entre les dysfonctions thyroïdiennes infracliniques d'une part, et la maladie coronarienne et la mortalité d'autre part. Les hypothyroïdies infracliniques affectent environ 4-5% de la population adulte alors que la prévalence de l'hyperthyroïdie infraclinique est inférieure (environ 1%). L'éventuelle association entre elles pourrait justifier un dépistage systématique des dysfonctions thyroïdiennes infracliniques. Les précédentes études sur l'association entre l'hypothyroïdie infraclinique et la maladie coronarienne ont donné des résultats conflictuels. La parution de nouveaux articles récents basés sur de grandes cohortes prospectives nous a permis d'effectuer une méta-analyse basée uniquement sur des études de cohorte prospectives, augmentant ainsi la validité des résultats. Résultats: 10 des 12 études identifiées pour notre revue systématique sont basées sur des cohortes issues de la population générale («population-based »), regroupant en tout 14 449 participants. Ces 10 études examinent toutes le risque associé à l'hypothyroïdie infraclinique (avec 2134 événements coronariens et 2822 décès), alors que 5 étudient également le risque associé à l'hyperthyroïdie infraclinique (avec 1392 événements coronariens et 1993 décès). En utilisant un modèle statistique de type random-effect model, le risque relatif [RR] lié à l'hypothyroïdie infraclinique pour la maladie coronarienne est de 1.20 (intervalle de confiance [IC] de 95%, 0.97 à 1.49). Le risque diminue lorsque l'on regroupe uniquement les études de meilleure qualité (RR compris entre 1.02 et 1.08). Il est plus élevé parmi les participants de moins de 65 ans (RR, 1.51 [IC, 1.09 à 2.09] et 1.05 [IC, 0.90 à 1.22] pour les études dont l'âge moyen des participants est >_ 65 ans). Le RR de la mortalité cardiovasculaire est de 1.18 (IC, 0.98 à 1.42) et de 1.12 (IC, 0.99 à 1.26) pour la mortalité totale. En cas d'hyperthyroïdie infraclinique, les RR de la maladie coronarienne sont de 1.21 (IC, 0.88 à 1.68), de 1.19 (IC, 0.81 à 1.76) pour la mortalité cardiovasculaire, et de 1.12 (IC, 0.89 à 1.42) pour la mortalité totale. Conclusions et perspectives : nos résultats montrent que les dysfonctions thyroïdiennes infracliniques (hypothyroïdie et hyperthyroïdie infracliniques) représentent un facteur de risque modifiable, bien que modéré, de la maladie coronarienne et de la mortalité. L'efficacité du traitement de ces dysfonctions thyroïdiennes infracliniques doit encore être prouvée du point de vue cardiovasculaire et de la mortalité. Il est nécessaire d'effectuer des études contrôlées contre placebo avec le risque cardiovasculaire et la mortalité comme critères d'efficacité, avant de pouvoir proposer des recommandations sur le dépistage des ces dysfonctions thyroïdiennes dans la population adulte.

Interventions hybrides et malformations cardiaques congénitales [Hybrid procedures in congenital heart disease]

La complexité croissante de la prise en charge des malformations cardiaques congénitales impose des interventions chirurgicales et des cathétérismes cardiaques interventionnels fréquents. Chacune de ces techniques a ces limitations propres. Les interventions hybrides associent les avantages de la chirurgie cardiaque et du cathétérisme interventionnel. Dans notre expérience, les thérapies hybrides permettent de diminuer le temps de circulation extracorporelle, de diminuer la morbidité des interventions chirurgicales, de raccourcir le séjour du patient aux soins intensifs. Pour certaines malformations cardiaques congénitales complexes pour lesquelles il n'existe pas de chirurgie ou de thérapie interventionnelle idéale, les interventions hybrides sont en train de s'imposer comme la prise en charge incontournable. Increasing complexity in management of congenital heart disease imposes more frequent surgeries and interventions. Each technique has its own limitations, which could impair the anticipated result. Hybrid procedures join the advantages of cardiac surgery and interventions, creating a synergy in the management of these patients with cardiac anomalies. In our experience, hybrid procedures shorten cardiopulmonary bypass, reduce morbidity of surgery and reduce duration of stay in the intensive care unit. For some complex congenital heart diseases for which there are no ideal surgical or interventional options, hybrid procedures are becoming increasingly important in their management. Finally hybrid procedures allow surgeons and cardiologist to achieve complex procedures that could not be possible in another way

Initial experience with hybrid surgery in congenital heart disease in a single center : P171

Introduction: A hybrid intervention is a joint procedure involving the interventional cardiologist and the cardiac surgeon. At our institution we have opted for this type of approach in congenital heart disease since 2005. We report here our initial experience. Cases: 1. A 3 year old boy with double aortic arch and multiple muscular ventricular septal defects (VSD),was readdressed for pulmonary band (PAB) removal and residual VSD closure after previous palliation. After surgical removal of the PAB, the surgeon provided a minimal transventricular access for placement of a 6mm Amplatzer® muscular VSD occluder by the cardiologist under transoesophageal guidance. The patient was extubated the same day and discharged after 5 days. 2. An 8 year old girl with Williams syndrome was followed for two large VSDs and severe peripheral pulmonary arteries (PA) stenosis. The membranous VSD was closed surgically, the muscular VSD during the same operation by direct placement of a 12 mm Amplatzer® muscular VSD occluder. During rewarming, balloon angioplasty of peripheral PA stenosis was achieved under fluoroscopy. Patient was extubated the following day and discharged after 8 days. 3. A 9 year old boy post tetralogy of Fallot repair had severe distal stenosis of the right ventricular to PA conduit.With patient on partial cardiopulmonary bypass, an incision was made on the conduit and a CP 8 Zig 16 stent placed on the stenosis. The child passed on full bypass and the definitive placement of the stent achieved. The child was extubated at the end of the intervention and discharged after 6 days. 4. A newborn presented at 2 days life with complex aortic arch anatomy: left aortic arch and right descending thoracic aorta perfused directly from a right arterial duct and left PA atresia. The arterial duct was stented with a Genesis XD stent dilated at 7mm. Two days later the cardiac surgeon made banded the right PA. The child was extubated after the operation and discharged a week later. Conclusion: Hybrid approach opens new ways of correction or palliation in congenital heart disease with encouraging results and less morbidity.

Thyroid antibody status, subclinical hypothyroidism, and the risk of coronary heart disease: an individual participant data analysis.

CONTEXT: Subclinical hypothyroidism has been associated with increased risk of coronary heart disease (CHD), particularly with thyrotropin levels of 10.0 mIU/L or greater. The measurement of thyroid antibodies helps predict the progression to overt hypothyroidism, but it is unclear whether thyroid autoimmunity independently affects CHD risk. OBJECTIVE: The objective of the study was to compare the CHD risk of subclinical hypothyroidism with and without thyroid peroxidase antibodies (TPOAbs). DATA SOURCES AND STUDY SELECTION: A MEDLINE and EMBASE search from 1950 to 2011 was conducted for prospective cohorts, reporting baseline thyroid function, antibodies, and CHD outcomes. DATA EXTRACTION: Individual data of 38 274 participants from six cohorts for CHD mortality followed up for 460 333 person-years and 33 394 participants from four cohorts for CHD events. DATA SYNTHESIS: Among 38 274 adults (median age 55 y, 63% women), 1691 (4.4%) had subclinical hypothyroidism, of whom 775 (45.8%) had positive TPOAbs. During follow-up, 1436 participants died of CHD and 3285 had CHD events. Compared with euthyroid individuals, age- and gender-adjusted risks of CHD mortality in subclinical hypothyroidism were similar among individuals with and without TPOAbs [hazard ratio (HR) 1.15, 95% confidence interval (CI) 0.87-1.53 vs HR 1.26, CI 1.01-1.58, P for interaction = .62], as were risks of CHD events (HR 1.16, CI 0.87-1.56 vs HR 1.26, CI 1.02-1.56, P for interaction = .65). Risks of CHD mortality and events increased with higher thyrotropin, but within each stratum, risks did not differ by TPOAb status. CONCLUSIONS: CHD risk associated with subclinical hypothyroidism did not differ by TPOAb status, suggesting that biomarkers of thyroid autoimmunity do not add independent prognostic information for CHD outcomes.

Indications for cardiovascular magnetic resonance in children with congenital and acquired heart disease: an expert consensus paper of the Imaging Working Group of the AEPC and the Cardiovascular Magnetic Resonance Section of the EACVI.

This article provides expert opinion on the use of cardiovascular magnetic resonance (CMR) in young patients with congenital heart disease (CHD) and in specific clinical situations. As peculiar challenges apply to imaging children, paediatric aspects are repeatedly discussed. The first section of the paper addresses settings and techniques, including the basic sequences used in paediatric CMR, safety, and sedation. In the second section, the indication, application, and clinical relevance of CMR in the most frequent CHD are discussed in detail. In the current era of multimodality imaging, the strengths of CMR are compared with other imaging modalities. At the end of each chapter, a brief summary with expert consensus key points is provided. The recommendations provided are strongly clinically oriented. The paper addresses not only imagers performing CMR, but also clinical cardiologists who want to know which information can be obtained by CMR and how to integrate it in clinical decision-making.
