ABSTRACT
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.

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.

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.

Persistent cyanosis is a frequent complication in the post-operative period of Sano modification of the Norwood procedure. It may be explained by a dynamic proximal shunt stenosis of the synthetic conduit that links the right ventricle to the pulmonary artery, as detected by echo cardiographic study. The use of beta-blockers in the post-operative period has been recently described in order to improve the arterial oxygen saturation. In this report, we describe the use of propranolol in two patients undergoing Sano modification of the Norwood procedure, in whom a gradient reduction in the synthetic conduit, increase in the levels of arterial oxygen saturation, decrease in heart rate, and increase in blood pressure were observed, thus resulting in clinical improvement. We conclude that the use of beta-blockers in these cases was beneficial.

OBJECTIVES: To describe a series of 8 consecutive infants (5 with transposition of the great arteries [TGA] and 3 with hypoplastic left heart syndrome [HLHS]) who underwent nonconventional septostomy techniques. BACKGROUND: For some complex congenital heart defects, an unrestrictive atrial septal defect (ASD) is essential to achieve an adequate cardiac output and/or systemic saturation. In some scenarios, the use of conventional septostomy techniques may be technically difficult, hazardous, and/or ineffective. METHODS: Use of transhepatic approach, cutting balloons, and radiofrequency perforation with stenting of the atrial septum. RESULTS: The size of the ASD and the oxygen saturation increased in all patients with no major complications. In those with TGA, the ASDs were considered to be of good size at the arterial switch operation. Two of the 3 patients with hybrid palliation for HLHS have developed some degree of obstruction within the interatrial stent over 2-3 months. At surgery, the stents were found to be secured within the septum with one showing significant fibrous ingrowth after uneventful removal. The other had some nonobstructive ingrowth. CONCLUSIONS: Creation or enlargement of ASDs in infants using new nonconventional transcatheter techniques is feasible, safe, and effective, at least in the short-to-mid-term follow-up. Infants with TGA seem to benefit the most because the procedure results in satisfactory clinical stability for subsequent early surgical intervention. In infants with HLHS palliated by a hybrid approach, stent implantation to the atrial septum seems to buy enough time to bring them to the phase II safely despite progressive in-stent obstruction.

A cianose persistente constitui complicação freqüente no pós-operatório da cirurgia de Norwood modificada por Sano. Sua ocorrência pode ser explicada pela obstrução dinâmica da anastomose proximal do conduto sintético, que liga o ventrículo direito ao tronco pulmonar, evidenciada à ecocardiografia. A fim de melhorar a saturação arterial de oxigênio, foi recentemente descrita a utilização de betabloqueador, no período pós-operatório. Neste relato, descrevemos a utilização de propranolol em dois casos de cirurgia de Norwood modificada por Sano, demonstrando diminuição do gradiente no tubo sintético, aumento dos níveis de saturação arterial de oxigênio, diminuição da freqüência cardíaca e aumento da pressão arterial, traduzido em melhora clínica. Concluímos que autilização de betabloqueador nesses casos mostrou-se benéfica.
