RESUMO
OBJECTIVE: To identify main complications in outpatient follow-up, as well as factors before or during operation that may interfere in patient's evolution. METHODS: Retrospective study of patients submitted to total cavopulmonary shunt with extracardiac conduit from 2000 to 2014 at the Hospital do Coração (São Paulo, Brazil) and who underwent clinical follow-up at this institution. RESULTS: One hundred and fifty surgeries were performed and 59 patients maintained outpatient follow-up. The mean age of these patients at the time of surgery was 4.45 years (median of 45 months) and 70.2% of them were males. Among the patients undergoing outpatient follow-up, postoperative time at evaluation ranged from 10 days to 145 months; 30 (50.8%) patients had single left ventricle and 29 (49.2%) had single right ventricle (48.2% of these presented with hypoplastic left heart syndrome [HLHS]). Patients with single left ventricle had a higher percentage of reintervention-free survival, but without statistically significant difference. 40% of the patients had no complications and 35% of them presented with thrombosis at some point in the follow-up period, with ventricular dysfunction being the second most frequently found complication (15% of cases), mainly among patients with single right ventricle morphology (P=0.04). Between the patients currently under follow-up, 20 (35%) of them had been evaluated by ultrasonography and had some degree of hepatic congestion and/or hepatomegaly. 16.7% of the patients with such alteration had HLHS (P=0.057). CONCLUSION: Except for the right ventricular morphology, no other factor has been shown to interfere in late evolution after total cavopulmonary shunt.

INTRODUCTION: Chylothorax is a lymphatic extravasation into pleural cavity and its incidence is 0.25%-5.3% in children undergoing cardiac surgery. OBJECTIVE: To evaluate the incidence of chylothorax in pediatrics patients operated, linking it in each surgical intervention. Evaluate treatment types and efficiency. METHODS: Retrospective study using medical records of children undergoing cardiac surgery in the Hospital do Coração between 2004 and 2014. For statistical analysis, qualitative variables by absolute frequency and relative frequency; quantitative variables, by median of 25 and 75 percentiles, as they did not present normal distribution (Shapiro-Wilk, P<0.05). The Chi-square test was used for the association between type of treatment and result. The adopted confidence level was 95%. RESULTS: Incidence of chylothorax was 2.1% (0.9% in intracardiac surgery, 1.7% correction of patent ductus arteriosus and aortic coarctation, 8.3% Glenn's surgery, 11.8% total cavopulmonary surgery and 3% in others). Among treatments, fasting associated with total parenteral nutrition (TPN) resolved 51% of the cases. Hypoglossal diet had failed treatment and surgical referral in 22% of the cases. Fasting with TPN associated with octreotide had success in the treatment of chylothorax in a period exceeding 15 days in 78% of cases, and 3.7% were referred for surgery. CONCLUSION: According to the results, incidence of chylothorax was 2.18%. Treatment with fasting and TPN leads to resolutions in 86.5%, and the association with octreotide was successful in 85.1% of cases, showing an efficient option, while the treatment with hypoglossal diet had therapeutic failure in 22% of the cases in which it was used.

OBJECTIVE: To compare the efficacy of aspirin and warfarin for prophylaxis of thrombosis in patients undergoing total cavopulmonary anastomosis. Evaluate whether coagulation factors (VII, VIII and protein C), clinical data, fenestration or hemodynamic factors, interfere with postoperative thrombosis. METHODS: A prospective, randomized study of 30 patients, randomized into Group I (Warfarin) and Group II (AAS), underwent total cavopulmonary shunt with extracardiac conduit, between 2008 and 2011, with follow-up by clinical visits to evaluate side effects and adhesion. Performed transesophageal echocardiography in post operatory time, 3, 6,12 and 24 months; angiotomography at 6, 12 and 24 months to evaluate changes in the internal tube wall or thrombi and pulmonary scintigraphy to evaluate possible PTE. RESULTS: Two deaths in group I; 33.3% of patients had thrombus (46.7% in Group II). The previous occurrence of thrombus and low levels of coagulation protein C were the only factors that influenced the time free of thrombus (P=0.035 and 0.047). Angiotomographic evaluation: 35.7% in group II presented material accumulation greater than 2 mm (P=0.082). Scintigraphy: two patients had PTE in group II. Five patients had difficulty to comply with the treatment, 4 in group I with INR ranging from 1 to 6.4. CONCLUSION: The previous occurrence of thrombus is a risk factor for thrombosis in the postoperative period. Patients using AAS tend to deposit material in the tube wall. The small sample size did not allow to conclude which is the most effective drug in the prevention of thrombosis in this population.

Dyslipidemia is one of the main risk factors associated with cardiovascular diseases. Few data on the impacts of congenital heart diseases are available with regard to the prevalence of dyslipidemia in children. Our study evaluated the lipid profile in children with congenital heart disease at a referral center. From January 2011 to July 2012, 52 pediatric patients had their lipid, metabolic and clinical profiles traced. The mean age was 10.4 ± 2.8 years and male/female rate of 1.38:1. Our population had 53.8% patients with high levels of total cholesterol and 13.4% (CI 95 %, from 6.6 to 25.2%) of them also presenting LDL levels ≥ 130 mg/dL, which characterizes dyslipidemia. The group of dyslipidemic patients presented only two obese individuals. Our data show that the presence of congenital heart disease does not lead to higher risk associated with the prevalence of dyslipidemia. Therefore, the screening of this specific population should follow the regular pediatric guidelines, which are also independent of the nutritional status of the children tested.

BACKGROUND: There is a scarcity of data comparing percutaneous and surgical closure of the secundum atrial septal defect (ASD). OBJECTIVES: Assessment of safety and efficacy of both methods of treatment in a referral center affiliated with the Ministry of Health. METHODS: Observational, prospective, non-randomized study of two cohorts of children and adolescents younger than 14 years, treated by catheterization or surgery. Data was collected prospectively in the percutaneous group (A) and retrospectively in the surgical group (B). RESULTS: A total of 75 patients (pts) were enrolled in group A from April 2009 to October 2011 and 105 pts were treated in group B from January 2006 to January 2011. Age was older and weight was higher in group B and the ASD diameter was similar in both groups. Technical success was achieved in all procedures and there were no deaths. Complications (most minor) occurred in 68% of group B and 4% of A (p < 0.001). Rates of total occlusion or non-significant residual shunts were similar in both groups. Median hospitalization time was 1.2 days in group A and 8.4 days in group B (p < 0.001). CONCLUSION: Both treatment modalities are safe and effective, showing excellent outcomes. However, the percutaneous treatment has lower morbidity and shorter in-hospital stay length. These observations support the concept that percutaneous treatment of atrial septal defects should be regarded as the method of choice to manage selected patients with this condition.

Avanços recentes na cardiologia pediátrica permitem que uma população crescente com cardiopatias congênitas chegue à idade adulta, muitos deles necessitando de seguimento por toda a vida. Um elemento chave desse seguimento é a avaliação seriada com métodos diagnósticos por imagem. O cardiologista pediátrico moderno dispõe atualmente de um vasto leque de opções não invasivas para a investigação desses pacientes, das quais se destaca como método principal a ecocardiografia e, como duas técnicas complementares, a ressonância magnética e a tomografia computadorizada. Neste artigo, faremos uma breve revisão dos princípios, indicações, vantagens e desvantagens de cada um destes métodos, em especial na investigação de indivíduos adultos com cardiopatias congênitas
Recent advances in pediatric cardiology allow an increasing population with congenital heart defects to reach adulthood, many of them requiring lifelong follow-up. A key element of this follow-up is serial evaluation by diagnostic imaging methods. The modern pediatric cardiologist currently has a wide range of noninvasive options for the investigation of these patients, the Echocardiogram stands out as the main tool, and as two complementary techniques, Magnetic Resonance and Computed Tomography. In this article we will briefly review the principles, indications, advantages and disadvantages of each of these methods, especially in the investigation of adult individuals with congenital heart diseases

We report a technique to palliate hypoplastic left heart syndrome, with no PDA stenting, but with double polytetrafluoroethylene shunt from pulmonary artery to ascending and descending aorta by combined thoracotomies. A 30-day-old female was operated with this technique. Five months after first operation, the child was submitted to Norwood/Glenn operation. Good hemodinamic recovery and initial clinical evolution was observed. The child was extubated in 8th post operatory day and reentubated in the next day due to pulmonary infection. Despite antibiotic treatment, the child died after systemic infectious complications.

Report of three cases of chylothorax and one case of chylous ascites in children who had undergone cardiac surgery with no response to routine clinical treatment, based on fasting and long-term parenteral nutrition. Treatment with octreotide at an initial dose of 1.0 mcg/kg/h was chosen, with a gradual increase of 1.0 mcg/kg/hr/day until a maximum dose of 4.0 mcg/kg/h. All cases had a favorable response, with gradual reduction of drainage output until prognosis improvement with no significant side effects.

A população de adolescentes e adultos com cardiopatia congênita é crescente graças às grandes inovações tecnológicas que permitiram avanços nos métodos diagnósticos, melhor conhecimento das cardiopatias congênitas, melhoria do tratamento clínico, surgimento da terapêutica intervencionista percutânea, aperfeiçoamento dos cuidados intensivose dos resultados cirúrgicos, aumentando assim a sobrevida destes pacientes. Algumas cirurgias apresentam resultados excelentes, enquanto outras, usualmente em portadores de cardiopatia congênita complexa, podem evoluir com lesões residuais importantes que ainda necessitarão de tratamento clínico e/ou cirúrgico ou pela hemodinâmica durante o seguimento. Entre outro grupo de pacientes, estão os pacientes não operados, que são diagnosticados ou encaminhados aos serviços especializados tardiamente. Alguns destes apresentam hipertensão pulmonar importante, ou já desenvolveram a síndrome de Eisenmenger e, portanto são inoperáveis, enquanto outros que se apresentam com cardiopatia como a comunicação interatrial, que costuma ser pouco sintomática nas primeiras duas décadas de vida, ou cardiopatias complexas balanceadas por algum grau de estenose pulmonar, que ainda poderão ser operados, mas sem a certeza do benefício da correção, pois estão predispostos a apresentar arritmia cardíaca e disfunção ventricular. Para que se possa oferecer a melhor abordagem, seja ela qual for, para esse grupo de pacientes, devemos continuar a buscar a formação de centros especializados para o atendimento aos adolescentes e adultos com cardiopatia congênita tratada ou não na infância, que cursam com lesões residuais ou hipertensão pulmonar. Além do aspecto técnico, não se pode desconsiderar a qualidade de vida desses pacientes, incluindo aspectos psicossociais e cognitivos.
The adolescent and adult population with congenital heart disease is growing, due to major technological innovations that have led to advances in diagnostic methods, better knowledge of congenital heart disease, improvements in clinical treatment, the emergence of percutaneous interventionist treatment, and the perfection of intensive care and surgical outcomes, all of which have increased the survival of these patients. Some surgical procedures present excellent results, while others, usually in individuals with complex congenitalheart disease, can develop with significant residual lesions that also require clinical and/or surgical treatment, or due to the hemodynamics during follow-up. Among another group ofpatients are those not operated on, who are diagnosed or referred to the specialized services too late. Some of these present significant pulmonary hypertension, or have alreadydeveloped Eisenmengers syndrome, and are therefore inoperable, while others presente heart disease such as inter-atrial communication, which generally has few symptoms in the first two decades of life, or complex heart disease balanced by some degree of pulmonarystenosis, who can still be operated on but without certainty of the benefit of correction, as they are predisposed to present cardiac arrhythmia and ventricular dysfunction. In order tooffer the best approach for this group of patients, whatever that may be, we must continue to strive for the formation of specialized centers for the care of adolescents and adults withcongenital heart disease, whether treated or not in infancy, and who also have residual lesions or pulmonary hypotension. In addition to the technical aspect, we must also consider thequality of life of these patients, including the psychosocial and cognitive aspects.

Objetivo: Comparar a eficácia do AAS e da Varfarina na profilaxia da trombose em pacientes submetidos a operação cavopulmonar total. Avaliar se fatores de coagulação (VII, VIII e Proteína C), dados clínicos, fenestração ou fatores hemodinâmicos, interferem na trombose no pós-operatório. Métodos: Estudo prospectivo e randomizado de 30 pacientes, randomizados em Grupo I (Varfarina) e Grupo II (AAS), submetidos à derivação cavopulmonar total com tubo extracardíaco, entre 2008 e 2011, com seguimento de dois anos. Foram realizadas consultas clínicas que avaliavam efeitos colaterais e aderência. Realizado ecocardiograma transesofágico no pós-operatório imediato, 3, 6,12 e 24 meses; angiotomografia aos 6, 12 e 24 meses de pós-operatório para avaliação de alterações na parede interna do tubo ou trombos e cintilografia pulmonar, para avaliar possível TEP. Resultados: Dois óbitos no grupo I; 33,3% dos pacientes apresentaram trombo (46,7% no Grupo II). A ocorrência prévia de trombo e baixos níveis de proteína C da coagulação foram os únicos fatores que influenciaram no tempo livre de trombo (P=0,035 e 0,047). Avaliação angiotomográfica: 35,7% dos pacientes do grupo II tinham atapeteamento maior que 2 mm (P=0,082). Cintilografia: dois pacientes apresentaram TEP no grupo II. Cinco pacientes tiveram dificuldade de aderência, 4 no grupo I com INR variando de 1 a 6,4. Conclusão: A ocorrência prévia de trombo é um fator de risco para trombose no pós-operatório. Pacientes em uso de AAS tendem a depósito de material na parede do tubo. O número reduzido da amostra não permitiu concluir qual a droga mais eficaz na prevenção da trombose na população estudada. .

BACKGROUND: The Transposition of the Great Arteries is the most frequent congenital cyanogenic cardiopathy in the neonatal period, corresponding to 7% of all congenital cardiopathies. Among the operations for surgical treatment, the Jatene operation, with arterial correction, is the treatment of choice. During the late postoperative evolution, some problems were observed, with the most common being the occurrence of supravalvular stenosis at the neopulmonary, regardless of the type of surgical technique used. OBJECTIVE: To study and analyze the prevalence of stenosis, as well as describe the surgical treatment and propose technical maneuvers to prevent its onset. METHODS: Of the 553 patients that underwent surgery, 409 were discharged from the hospital and 281 had late follow-up; 59 (20.9%) presented different degrees of supravalvular pulmonary stenosis and 21 had a mean gradient > 60 mmHg, needing surgical treatment. Depending on the location and anatomy of the stenosis, the surgical treatment consisted of the use of different techniques, such as the enlargement of stenosis areas with bovine pericardium patches, resection of stenotic areas and termino-terminal anastomosis, replacement of retracted patches and synthetic tubes. RESULTS: Twenty patients presented good evolution and only one patient died. CONCLUSION: It can be concluded that the supravalvular pulmonary stenosis, post-Jatene operation for Transposition of Great Arteries, had a prevalence of 20.9%; once identified and with indication for treatment, it can be treated surgically with low mortality levels, through different surgical techniques; to prevent the occurrence of stenosis, ample dissection and release of the pulmonary branches, double anastomoses, large patches of autologous pericardium and careful reconstruction of the aorta are proposed, which prevents the compression of the neopulmonary.

FUNDAMENTO: Há uma paucidade de dados comparando o método percutâneo e o cirúrgico para tratamento da comunicação interatrial tipo ostium secundum. OBJETIVOS: Análise de segurança e eficácia comparando ambos os métodos tratamento em um hospital excelência com vÃnculo o Ministério de Saúde. MÃTODOS: Estudo observacional, prospectivo, não randomizado de duas coortes de crianças e adolescentes < 14 anos tratadas por meio do cateterismo intervencionista (grupo A) ou da cirurgia cardÃaca convencional (grupo B). A coleta dos dados foi prospectiva no grupo A e retrospectiva no B. RESULTADOS: De abr/2009 a out/2011 foram alocados 75 pts no grupo A e entre jan/2006 e jan/2011foram tratados 105 pts no grupo B. A idade e o peso dos pacientes foram maiores no grupo B e o diâmetro da comunicação interatrial do tipo ostium secundum foi semelhante entre os grupos. Sucesso técnico foi observado em todos os procedimentos e não houve óbitos. Complicações (a maioria menores) foram encontradas em 68% no grupo B e em 4% do grupo A (p < 0,001). As taxas de fluxo residual não significativo ou de oclusão total do defeito foram semelhantes nos dois grupos. A mediana de internação foi de 1,2 dias após o procedimento percutâneo e 8,4 dias após a correção cirúrgica (p < 0,001). CONCLUSÃO: Ambos os tratamentos são seguros e eficazes com ótimos desfechos, porém o tratamento percutâneo apresenta menor morbidade e tempo de internação. Tais observações embasam a visão que essa forma de tratamento deve ser, hoje em dia, o método de escolha para pacientes selecionados com CIA do tipo ostium secundum.
