As malformações cardíacas congênitas (MCCs) são as malformações mais comuns ao nascimento, representando uma importante causa de morbidade e mortalidade em recém-nascidos. Nos últimos anos, estudos utilizando testes citogenômicos têm permitido elucidar e compreender melhor as causas das MCCs. O objetivo geral desse estudo foi investigar a presença de CNVs em amostras de tecido obtidas post-mortem de portadores de malformações cardíacas congênitas sindrômicas; e os objetivos específicos consistiram em avaliar a frequência das CNVs, destacando as mais relevantes, comparar a presença de CNVs nos diferentes tecidos e realizar a correlação genótipo-fenótipo. Para isso, foram estudados um total de 52 casos de natimortos e recém-nascidos provenientes do Serviço de Verificação de Óbitos - FMUSP. Amostras de DNA extraídas da pele, diafragma e do coração foram avaliadas utilizando o kit AmpFlSTR® MiniFiler(TM) PCR Amplification (Life Technologies(TM), USA) e a técnica de Multiplex Ligation-dependent Probe Amplification (MLPA) com diferentes kits (MCR-Holland, Holanda). A técnica de FISH foi utilizada para a confirmação dos resultados obtidos em um dos casos estudados. Foram encontradas CNVs relevantes em 21 casos, incluindo trissomia do 18 (10 casos), trissomia do 21 (4 casos), trissomia do 13 (2 casos), trissomia do 16 (1 caso), monossomia do X em mosaico (1 caso), dup 4p16 (1 caso), dup 11q25 (1 caso) e del GATA4 éxon 6 (1 caso). A análise genômica se mostrou eficiente na investigação das bases genômicas e na caracterização das diferentes malformações em amostras post-mortem de portadores de MCC sindrômicas / Congenital heart defects (CHDs) are the most common birth defect and represent an important cause of morbidity and mortality in newborns. In recent years, studies using cytogenomic tests have enabled an improved understanding of the causes of CHD. The general objective of this study was to investigate the presence of CNVs in post-mortem tissue samples from patients with congenital syndromic cardiac malformations; and the specific objectives were to evaluate the frequency of CNVs, highlighting the most relevant ones, to compare the presence of CNVs in the different tissues and to perform the genotype-phenotype correlation. For this, a total of 52 stillbirth and newborn cases from the Death Verification Service (SVO), FMUSP were investigated. DNA samples from skin, diaphragm and heart tissues were evaluated using an AmpFlSTR® MiniFiler(TM) PCR Amplification Kit (Life Technologies(TM), California, USA) and Multiplex Ligation-dependent Probe Amplification (MLPA) with different kits (MCRHolland, Amsterdam, The Netherlands). FISH was used to confirm the results of one of the studied cases. The results showed relevant copy number variations (CNVs) in 21 cases, including trisomy 18 (10 cases), trisomy 21 (4 cases), trisomy 13 (2 cases), trisomy 16 (1 case), mosaic monosomy X (1 case), dup 4p16 (1 case), dup 11q25 (1 case) and del GATA4 exon 6 (1 case). Genomic analysis was found to efficiently identify the genomic basis of, and characterize, various malformations found in postmortem samples from syndromic CHD carriers

INTRODUÇÃO: Os defeitos cardíacos congênitos (DCC) são um grupo de anormalidades estruturais mais prevalentes ao nascimento e uma das principais causas de morbidade e mortalidade infantil. Os fatores genéticos são importantes na etiologia dos DCC. Estudos têm mostrado a contribuição da variação no número de cópias (CNV) na gênese das malformações cardíacas. A deleção 22q11.2 é a causa mais comum de microdeleção humana e está relacionada com defeito cardíaco (DCC) conotruncal. O MLPA (Multiplex Ligation-dependent Probe Amplification) é um método eficaz para detectar microdeleções/microduplicações em pacientes com DCC. OBJETIVO: Detectar a presença da variação no número de cópias gênicas em pacientes portadores de cardiopatia conotruncal pela técnica de MLPA e associar ao fenótipo do paciente. MÉTODOS: Foram avaliados 39 pacientes (23 do sexo masculino, 16 do sexo feminino) com idade entre 2 dias e 19 anos (mediana de 6 anos), todos com cardiopatia conotruncal, a maioria dos pacientes (56%) apresentavam tetralogia de Fallot. Avaliação clínica e laboratorial foi realizada em todos os pacientes. O cariótipo foi normal em todos pacientes. MLPA foi realizada com os kits P064, P036/P070 e P250. RESULTADOS: Foram detectadas CNVs em sete pacientes: deleção 22q11.2, duplicação 22q11.2, duplicação 15q11.2, duplicação 20p12.2, deleção 19p, duplicação 15q e duplicação 8p23.2 com duplicação 10p12.31. As cardiopatias encontradas nestes pacientes foram: dupla via de saída de ventrículo direito (2), coartação da aorta, tetralogia de Fallot (3) e transposição de grandes artérias. Os achados clínicos extracardíacos encontrados nestes pacientes foram dismorfismo facial, dente neonatal, atrofia e displasia cerebral, atresia duodenal, dificuldade de aprendizado, insuficiência velofaríngea, aplasia de timo, refluxo gastroesofágico, hérnia umbilical, asma, infecções de vias aéreas frequente, déficit de crescimento e somente três apresentavam retardo no desenvolvimento neuropsicomotor (dup 15q11.2, dup 15q, del 22q11.2). As características clínicas foram compatíveis com o relatado na literatura associado com a microdeleção/microduplicação encontrada. Nenhuma destas alterações foram herdadas de seus pais testados em seis casos. CONCLUSÃO: O uso do MLPA possibilitou a detecção de CNVs em pacientes com DCC. O diagnóstico precoce das CNVs em pacientes com DCC auxilia na prevenção de morbidade e diminuição da mortalidade nestes pacientes, contudo em um país com regiões com poucos recursos laboratoriais genéticos uma avaliação clínica minuciosa em todo paciente com DCC é imprescindível para direcionar qual melhor exame deve ser realizado / INTRODUCTION: Congenital heart defects (CHD) are a group of structural abnormalities most prevalent birth and a major cause of infant morbidity and mortality. Genetic factors are important in the etiology of CHD. Studies have shown the contribution of copy number variation (CNV) in the genesis of cardiac malformations. The deleletion 22q11.2 is the most common cause of human microdeletion and is related conotruncal cardiac defect (DCC). The MLPA (Multiplex Ligation-dependent Probe Amplification) is an effective method to detect microdeletions/micoduplications in patients with CHD. PURPOSE: Detect the presence of gene copies number variation in the patients with conotruncal heart defect by MLPA technique and associate the phenotype of the patient. METHODS: 39 patients (23 males, 16 females) aged 2 days old - 19 years old (median= 6 years old) with conotruncal cardiac defect were evaluated. Tetralogy of Fallot was more prevalent heart defect (56%). All patients were evaluated clinical and laboratory. Karyotypes were normal in all pacients. MLPA was performed with the P064, P036/P070 and P250 kits. RESULTS: CNVs were detected in seven patients: 22q11.2 deletion, 22q11.2 duplication, 15q11.2 duplication, 20p12.2 duplication, 19p deletion, 15q duplication and 8p23.2 duplication with 10p12.31 duplication. The congenital heart defect found in these patients were: double outlet right ventricle (2), coarctation of the aorta, tetralogy of Fallot (3) and transposition of the great arteries. Clinical findings in these patients were facial dysmorphism, neonatal tooth, brain atrophy and dysplasia, duodenal atresia, learning disabilities, velopharyngeal insufficiency, thymic aplasia, gastroesophageal reflux, umbilical hernia, asthma, frequent infections of the airways , failure to thrive, and only three had delayed psychomotor development (dup 15q 11.2, dup 15q, del 22q11.2) The clinical features were consistent with those reported in the literature associated with the microdeletion /microduplication found. None of these alterations were inherited from six parents tested. CONCLUSIONS: MLPA was effective to detect CNVs in patients with CHD. Early diagnosis of CNVs in patients with CHD assists in preventing morbidity and decreased mortality in these patients, however, in a country with regions with few genetic laboratory resources a thorough clinical evaluation in all patients with CHD is essential to direct which should be further analyzed performed

La fermeture percutanée est le traitement de référence des communications interatriales (CIA). Après son implantation, une cicatrisation du dispositif est classiquement attendue après quelques mois ; il semble cependant qu’un recouvrement incomplet ou partiel puisse être observé dans de rares cas, sans que l’on en connaisse les mécanismes impliqués. Cette cicatrisation imparfaite du dispositif est associée à la survenue de complications retardées. Dans le cadre de cette thèse nous avons étudié la cicatrisation de ces prothèses de CIA, en nous focalisant sur les processus de recouvrement et d’endothélialisation des dispositifs, à travers une approche translationnelle incluant expérimentations in vitro, modèle animal chronique et étude clinique. A la fin de ce travail, il est possible de conclure que : 1) il existe des cas de complications au long cours après fermeture de CIA, liées à un défaut de recouvrement du dispositif, 2) sur une large cohorte pédiatrique avec un suivi allant jusqu’à 18 ans après l’implantation, l’incidence de ces complications est faible 3) les modèles animaux, utilisés seuls, ne peuvent suffire à expliquer ni à avancer dans la compréhension de ce phénomène, 4) il n’existe pas de différences significatives concernant le processus de recouvrement entre les 3 prothèses analysées au cours de ce travail, 5) une évaluation non invasive et individualisée du recouvrement prothétique , grâce aux techniques d’imagerie, est une perspective prometteuse. Ces données montrent qu’une meilleure compréhension du processus de recouvrement prothétique passe par la réalisation conjointe d’études fondamentales et cliniques. Cependant, le développement d’outils permettant une évaluation individualisée du recouvrement doit être poursuivi, du fait de leur fort potentiel de translation clinique et de leur capacité à optimiser la prise en charge du patient. / The percutaneous device closure is the gold treatment of atrial septal defect (ASD). After implantation, device healing is classically expected following several months; however, an incomplete or partial covering of the device may be observed without a full knowledge of the underlying mechanisms. In this thesis we studied the healing of these intracardiac prostheses, focusing on the covering and endothelialization processes of devices, approach through a translational approach including in vitro experiments, chronic animal model and clinical study. At the end of this work, it is possible to conclude that 1) there are cases of long-term complications after closure of CIA, related to a lack of recovery of the device, 2) in a large cohort of pediatric with a follow up of up to at 18 years after implantation, the incidence of these complications is low 3) animal models, used alone, can not suffice to explain or improve the understanding of this complex process, 4) there is no significant differences in the covering process between the 3 prostheses analyzed during this work, 5) a non-invasive and individualized assessment of prosthetic recovery, using imaging techniques, is a promising perspective with significant potential for clinical translation . These data show that a better understanding of device healing process needs the joint undertake of basic and clinical studies. Moreover, the development of tools for individualized assessment of device covering should be pursued in parallel, due to their high translational potential, in order to optimize patient management.

Single ventricle heart defects, where systemic and pulmonary venous returns mix in the single functional ventricle, represent the most complex form of congenital heart defect, affecting 2 babies per 1000 live births. Surgical repairs, termed "Fontan Repairs," reroute the systemic venous return directly to the pulmonary arteries, thus preventing venous return mixing and restoring normal oxygenation saturation levels. Unfortunately, these repairs are only palliative and Fontan patients are subjected to a multitude of chronic complications. It has long been suspected that hemodynamics play a role in determining patient outcome. However, the number of anatomical and functional variables that come into play and the inability to conduct large scale clinical evaluations, due to too small a patient population, has hindered decisive progress and there is still not a good understanding of the optimal care strategies on a patient-by-patient basis. Over the past decades, image-guided computational fluid dynamics (CFD) has arisen as an attractive option to accurately model such complex biomedical phenomena, providing a high degree of freedom regarding the geometry and flow conditions to be simulated, and carrying the potential to be automated for large sample size studies. Despite these theoretical advantages, few CFD studies have been able to account for the complexity of patient-specific anatomies and in vivo pulsatile flows. In this thesis, we develop an unstructured Cartesian immersed-boundary flow solver allowing for high resolution, time-accurate simulations in arbitrarily complex geometries, at low computational costs. Combining the proposed and validated CFD solver with an interactive virtual-surgery environment, we present an image-based surgical planning framework that: a) allows for in depth analysis of the pre-operative in vivo hemodynamics; b) enables surgeons to determine the optimum surgical scenario prior to the operation. This framework is first applied to retrospectively investigate the in vivo pulsatile hemodynamics of different Fontan repair techniques, and quantitatively compare their efficiency. We then report the prospective surgical planning investigations conducted for six failing Fontan patients with an interrupted inferior vena cava and azygous continuation. In addition to a direct benefit to the patients under consideration, the knowledge derived from these surgical planning studies will also have a larger impact for the clinical management of Fontan patients as they shed light onto the impact of caval offset, vessel flaring and other design parameters upon the Fontan hemodynamics depending on the underlying patient anatomy. These results provide useful surgical guidelines for each anatomical template, which could benefit the global surgical community, including centers that do not have access to patient-specific surgical planning interfaces.

nÃo hà / A PolÃtica Nacional de AtenÃÃo Cardiovascular de Alta Complexidade com foco na Cirurgia Cardiovascular PediÃtrica, formalizada em 15 de junho de 2004, por meio das Portarias NÂ1169/GM e N 210 SAS/MS, à gestada por intervenÃÃo da SBCCV e DCCVPed junto ao MinistÃrio da SaÃde e se propÃe atender a demanda em cirurgia cardiovascular pediÃtrica. à Ãpoca da formulaÃÃo, os deficits em cirurgias eram expressivos, sendo mais crÃticos nas regiÃes Norte e Nordeste. A pesquisa objetiva avaliar a polÃtica quanto ao desenho, implementaÃÃo e resultados. Foram empregados mÃtodos quantitativos para anÃlise de dados primÃrios dos questionÃrios, aplicados aos cirurgiÃes e secundÃrios coletados no MS/DATASUS e IBGE. O recorte temporal foi de 1999 a 2008 para os procedimentos em cardiopatias congÃnitas e de 2001 a 2008 para os valvares. Os qualitativos foram empregados para anÃlise das portarias e discursos de diretores de sociedades e gestores do MS. As anÃlises foram balizadas nas premissas do Sistema Ãnico de SaÃde, equidade, integralidade e regionalizaÃÃo, à luz de alguns autores. Os resultados demonstram ser a polÃtica um marco, pelo fato de reconhecer caracterÃsticas e necessidades particulares na Ãrea. Carece porÃm, de medidas que visem otimizar a frequÃncia de procedimentos ainda com deficits significativos - 62% para o Brasil e 91%, 76%, 55%, 36% e 47% para as regiÃes Norte, Nordeste, Sudeste, Sul e Centro-Oeste, respectivamente, e resolver iniquidades regionais. A polÃtica Ã, à anÃlise empregada, ineficaz e ineficiente. Como estratÃgias que visam a subsidiar aÃÃes de governanÃa, encontraram-se: realinhar valores de pagamento por procedimento; implementar banco de dados em parceria com o DCCVPed; compatibilizar tabelas de diagnÃstico, procedimentos e Ãrteses e prÃteses; identificar centros de excelÃncia em cardiopatias complexas e defini-los como de referÃncia regional; patrocinar centros para treinamento profissional; valorizar honorÃrios; subsidiar reestruturaÃÃo das instituiÃÃes habilitadas e estruturaÃÃo daquelas que entrarem no sistema; estabelecer polÃtica de equidade regional; criar Programa de PrevenÃÃo e Controle da Febre ReumÃtica. Em suma, entende-se a polÃtica como desencadeadora de um processo de estruturaÃÃo e que a avaliaÃÃo continuada poderà trazer subsÃdios fundamentados e ser ferramenta de persuasÃo junto ao poder constituÃdo. / The National Cardiovascular Care High Complexity Policy, focusing on Pediatric Cardiovascular Surgery, formalized on June 15, 2004, through Ordinance NÂ. 1169/GM N and 210 SAS / MS is fomented by the intervention from the SBCCV and DCCVPed together with the Ministry Health and aims to meet the demand in pediatric cardiovascular surgery. At the time of the formulation the deficits in surgeries were expressive, being more critical in the North and Northeast. The research aims to evaluate the policy on its design, implementation and results. We used quantitative methods for analysis of primary data from questionnaires administered to surgeons and secondary collected from the MS / DATASUS and IBGE. The time frame was 1999 to 2008 for procedures in congenital heart disease and from 2001 to 2008 for the valve procedures. The qualitative analyses were used for the entrances and speeches by corporate directors and managers of MS. Analyses were buoyed on the premises of the National Health System, as fairness, integrity and regionalization in the light of some authors. The results have proved to be a landmark policy by recognizing the characteristics and particular needs in the area. However, there is lack of measures to improve the frequency of the procedures, still with significant deficits, 62% for Brazil and 91%, 76%, 55%, 36% and 47% for the north, northeast, southeast, south and central west respectively, and resolve regional inequities. Politics is, according to the the analysis employed, ineffective and inefficient. As strategies to support governance actions met: realign payment amounts per procedure; implement database in partnership with DCCVPed; tables reconcile the diagnostic procedures with the orthesis and prosthesis, identify centers of excellence in complex heart and set them as reference regional centers to sponsor professional training value fees, subsidize the restructuring of the institutions empowered and structuring those who enter the system, establish policy for regional equity, create Program Prevention and Control of Rheumatic Fever. In sum, it means the policy as a trigger of a process of structuring and continuous evaluation that will provide input and be a tool to persuade the powers that be.

Farah MCK. Disfunção ventricular no pós-operatório da intervenção cirúrgica para correção dos defeitos congênitos da Tetralogia de Fallot. Estudo de correlação clínica e anatomopatológica [tese]. São Paulo: Faculdade de Medicina, Universidade de São Paulo; 2008. 136p. O estudo investigou de modo prospectivo o remodelamento ventricular histopatológico em crianças submetidas à correção cirúrgica de Tetralogia de Fallot (TF) com o objetivo de detectar possíveis fatores associados aos indicadores ecocardiográficos de disfunção ventricular sistólica e diastólica no período pós-operatório. Pacientes e métodos: foram incluídos 23 pacientes consecutivos portadores de TF (14 masculinos), com idade entre 12 e 186 meses (média=39,6 meses, mediana = 23 meses). A análise do Doppler Tecidual (índice de aceleração isovolumétrica - AVI, velocidade miocárdica sistólica - S\', velocidade miocárdica diastólica precoce - E\') foi realizada em três momentos: antes da cirurgia, nos primeiros três dias de PO e entre 30 a 90 dias após a cirurgia. Durante a cirurgia, além das bandas musculares infundibulares, foram obtidas biópsias subendocárdicas na via de entrada do VD e do VE. Foram avaliados quanto ao grau de hipertrofia miocárdica, colágeno intersticial (picorsirius) e capilaridade (imunohistoquímica-fator VIII). Níveis séricos de troponina T foram mensurados antes e após a cirurgia. Eletrocardiogramas realizados antes e após a cirurgia, características clínicas e uso prévio de propranolol foram avaliados. Este estudo foi aprovado pela comissão de ética da CPPESQUSP. Resultados: Os cardiomiócitos do VD mostraram acentuada hipertrofia. O colágeno intersticial esteve aumentado em ambos os ventrículos. A área ocupada por capilares não diferiu entre as diversas regiões estudadas. Houve diminuição significativa do AVI do VD no terceiro ecocardiograma (p=0,006) o que se correlacionou de modo negativo e significativo com o diâmetro dos cardiomiócitos da via de entrada do VD (r=-0,59; p=0,006). As velocidades de E\' do VD, diminuíram significativamente nos dois períodos pós-operatórios (p<0,001) e tiveram correlação negativa significativa com a porcentagem de colágeno intersticial (r= -0,525; p=0,004). Os níveis séricos de Troponina T aumentaram significativamente em todos os pacientes no período pós-operatório- 27,7 ±18,6 ng/ml e 15,9+11,3 ng/ml respectivamente no segundo e terceiro PO e se correlacionaram de modo positivo e significativo com o tempo de circulação extra corpórea e com o tempo de anoxia (p=0,019 e 0,018, respectivamente) e maior tempo de uso de droga vasoativa no pós-operatório (r=0,552, p=0,006). A duração do QRS aumentou significativamente no PO. Os pacientes que apresentaram aumento do QRS maior que 40ms, também apresentaram maior porcentagem de colágeno intersticial na via de entrada do VD. Conclusão: o remodelamento miocárdico presente no período pré-operatório, a julgar pela avaliação histopatológica morfométrica da hipertrofia celular e colágeno intersticial, influenciou respectivamente a função sistólica e diastólica do ventrículo direito no período pós-operatório da correção cirurgia da Tetralogia de Fallot. / It was investigate prospectively the histopathological myocardial remodeling in children submitted to surgical repair of Fallot\'s tetralogy, in order to detect possible factors associated to postoperative (PO) echocardiographic findings of systolic or diastolic ventricular dysfunction. Patients and Methods: 23 consecutive Fallot patients (14 males), aged 12 to 186 months (mean=39.6, median=23 months) were enrolled in the study. Tissue Doppler echocardiographic analysis (isovolumic acceleration-IVA, systolic myocardial velocity-S\' and early diastolic myocardial velocity-E\') was performed in three moments for both ventricles: before surgery, within the first three postoperative days and later, between the 30th and 90th PO days. During surgery, besides the anomalous infundibular bands resected, subendocardial biopsy samples from the right ventricular (RV) inflow tract and of the left ventricle (LV), through the ventricular septal defect, were obtained for histopathological morphometric evaluation: degree of cell hypertrophy, interstitial collagen (Sirius-red) and capillarity (immunohistochemistry against Factor-VIII). Troponin-T levels were measured before and after surgery. The electrocardiogram performed before and after surgery, some clinical features and previous use propranolol were considered. This study was approved by the Ethical Committee of our Institution. Results: the right ventricular cardyomyocytes showed a significant hypertrophy. The interstitial collagen was increase in both right and left ventricle. The capillary area fraction did not differ among the biopsy samples analyzed. IVA of the RV decreased significantly at the third echocardiographic evaluation (p=0.006) and correlated negatively with the diameter of the RV cardyomyocytes (r= -0.59; p=0.006). E\' measured at the RV decreased significantly in both PO periods (p<0.001) and showed a significant negative correlation with the percentage of interstitial myocardial collagen (r=-0.525; p=0,044). Troponin-T levels increased postoperatively in all patients (27.7 ±18,6ng/ml and 15.9+11.3ng/ml - second and third PO days) and correlated positively with the cardiopulmonary bypass and cross clamping times (p=0.019 and 0.018 respectively). The QRS interval increased significantly in the PO period. The patients in whom the PO electrocardiogram showed an increase of the QRS greater than 40ms, showed a greater interstitial collagen area fraction in the right ventricle inflow tract. Conclusions: Myocardial remodeling present preoperatively, as judged by the morphometric histopathological evaluation of cell hypertrophy and interstitial collagen, influenced respectively the medium term PO systolic and diastolic right ventricular function of repaired Fallot patients.

I Sverige idag föds cirka 1000 barn årligen med medfödda hjärtfel. Dessa hjärtfel kan variera i allvarlighetsgrad och ge olika symtom beroende på typ av hjärtfel. Många kan leva ett ganska vanligt liv medan andra har symtom och upplever hjärtfelet begränsande i deras vardag. Då ungdomstiden och de tidiga vuxenåren är känsliga faser i en människas liv, med bland annat identitetssökning och en tid för strävan mot självständighet, är det viktigt att veta hur dessa hjärtfel påverkar ungdomarna och de unga vuxna för att kunna hjälpa dem mot en positiv upplevelse av sin livsvärld. Syftet var att beskriva ungdomars samt unga vuxnas upplevelse av att leva med medfött hjärtfel. För att svara på syftet genomfördes en litteraturöversikt där 16 studier inhämtades från 2007 och framåt, utifrån databaserna PubMed och CINAHL. Resultatet visade att ungdomarna och de unga vuxna hade olika upplevelser av sitt medfödda hjärtfel. En del hade accepterat sin sjukdom och upplevde ingen påverkan på vardag eller livskvalitet. Andra upplevde svårigheter att acceptera sin sjukdom, att integrera den i sin vardag och kände sig begränsade av sitt hjärtfel. Livskvaliteten påverkades också negativt på olika sätt hos några ungdomar. Många upplevde också en oro och osäkerhet gällande framtiden. Omgivningen och sjukvården påverkade ungdomarnas och de unga vuxnas upplevelse av sin livsvärld. Föräldrar upplevdes antingen stöttande eller överbeskyddande och kamrater upplevdes kunna påverka livsvärlden negativt eller positivt beroende på hur de bemötte ungdomarna och de unga vuxna och deras begränsningar. En stark känsla av sammanhang, socialt stöd, färre symtom av hjärtfelet och en högre självskattad fysisk status gav en mer positiv upplevelse av livsvärlden. Utifrån resultatet dras slutsatsen att ett medfött hjärtfel påverkar vardagen på olika sätt för ungdomar och unga vuxna. Vårdpersonal som möter denna patientgrupp behöver kunskap om vad som bidrar till en god livskvalitet för personer med medfött hjärtfel, liksom kunskap om de faktorer som predisponerar för upplevelsen av en god livsvärld. Därtill behöver de kunna förmedla nödvändiga verktyg för att uppnå densamma. / In Sweden about 1000 children are born every year with congenital heart defects. These congenital heart defects vary in complexity and cause different symptoms depending on the type of heart defect. Many of the children are able to live normal lives, while others have symptoms and feel that the heart defect is limiting in their daily life. Since adolescence and early adulthood are vulnerable phases in life during which young people seek to establish identity and to achieve independence it is important to know how these heart defects affect adolescents and the young adults to be able to help them experience a positive life world. The aim was to describe the experience of adolescents and young adults living with a congenital heart defect. A literature review was performed and 16 articles were obtained from 2007 and forward, from the databases PubMed and CINAHL. The results showed that adolescents and young adults had different experiences of their congenital heart defects. Some of them had accepted their disease and experienced no impact on daily life or quality of life. Others experienced difficulties in accepting their disease and in integrating it into their daily life and felt that the heart defect limited them. Quality of life was negatively affected in various ways for some of the adolescents. Many of them experienced anxiety and uncertainty for the future. The adolescents and young adults were also affected by the people in their environment and the health care. They felt that their parents either supported or overprotected them and described the effect of their friends on them as either positive or negative, depending on how those friends responded to the adolescents and young adults and their limits. A strong sense of coherence, social support, less symptoms from the heart defect and a higher self rated physical status gave a more positive experience of the life-world. From the result the conclusion is made; that living with a congenital heart defect affects daily life in different ways. Health professionals who meet these patients need knowledge about which factors predispose patients to experiencing a good life world and knowledge about factors that contributes to a good quality of life for persons with congenital heart defects and they need to be able to give them necessary tools to achieve the same.

Various skeletal abnormalities, including chest deformity, have been reported with Turner's syndrome. We report radiologic findings of the sternum on lateral chest roentgenograms in 15 children and adolescents with Turner's syndrome, whose ages ranged between 2 weeks and 20 years. Eight had associated congenital heart disease (CHD). Twelve patients (80 percent) had various sternal abnormalities; 5 had short sternum, 3 had premature fusion of the manubrio-sternal junction, and 4 had premature fusion of the mesosternum. Five had decreased ratio of sternal body to manubrium. Three patients had two ossification centers of the manubrium. Four patients had bowing of the mesosternum; three of these had mild pectus excavatum also. In this series, children with and without CHD had similar sternal abnormalities. Although not pathognomonic, sternal abnormalities on a lateral chest roentgenogram are common skeletal abnormalities associated with Turner's syndrome and are independent of associated CHD. In our series of 15 patients, 10 had monosomy (45,X) on blood karyotype; 7 of them had associated CHD. This is the first systematic analysis of radiologic abnormalities of the sternum in Turner's syndrome and includes findings not previously reported.
