ABSTRACT

RESUMEN Introducción: El abordaje híbrido implica la colaboración estrecha de los equipos quirúrgico y de hemodinamia para el tratamiento de cardiopatías congénitas complejas, con el objetivo de disminuir el número de intervenciones a través de técnicas menos invasivas y de evitar las limitaciones dadas por el tamaño de los accesos vasculares y la utilización de circulación extracorpórea. Objetivos: Evaluar indicaciones, técnicas, resultados iniciales y seguimiento a corto plazo del abordaje híbrido. Material y métodos: Revisión retrospectiva de pacientes abordados de manera híbrida desde marzo de 2014 hasta septiembre de 2020. Se realizaron 14 procedimientos en 13 pacientes. Edad media de 16,8 meses (1 día-13 años), el 50% fueron neonatos y el 57% de sexo masculino; el peso medio fue 9 kg (1,9-70 kg). Los procedimientos híbridos realizados incluyeron implante de stent en coartación de aorta (4 pacientes), implante de stent ductal (3 pacientes), implante de stent ramas pulmonares (1 paciente), valvuloplastia aórtica neonatal (4 pacientes) y cierre de comunicación interventricular muscular (2 pacientes). El acceso se realizó mediante disección carotídea en 8 procedimientos y esternotomía en los 6 restantes. Resultados: Todos los procedimientos pudieron completarse exitosamente, aunque un paciente presentó fibrilación ventricular posprocedimiento y otro falleció durante el posoperatorio inmediato debido a trastorno grave de la coagulación. El seguimiento de los 12 pacientes restantes fue en promedio de 19 meses y la evolución fue favorable. Conclusiones: Utilizando una estrategia híbrida, los resultados iniciales en términos de sobrevida y mejoramiento de parámetros hemodinámicos fueron adecuados. La selección de casos, el trabajo en equipo y el seguimiento apropiado son cruciales para lograr resultados satisfactorios.


ABSTRACT Background: The hybrid approach implies the close collaboration between surgical and interventional cardiology teams for the treatment of complex congenital heart diseases to reduce the number of interventions by using less invasive techniques, avoid the limitations due to the size of vascular accesses and the use of cardiopulmonary bypass. Objectives: The aim of this study is to evaluate the indications, techniques, initial results and short-term follow-up of the hybrid approach. Methods: We conducted a retrospective analysis of patients treated with hybrid approach between March 2014 and September 2020. Fourteen procedures were performed in 13 patients. Mean age was 16.8 years (1 day-13 years); 50% were neonates, 57% were male and mean weight was 9 kg (1.9-70 kg). The hybrid procedures performed included stenting in coarctation of the aorta (4 patients), ductal stenting (3 patients), stenting of pulmonary artery branches (1 patient), neonatal aortic valvuloplasty (4 patients) and perventricular closure of muscular ventricular septal defect (2 patients). The access used was dissection of the carotid artery in 8 procedures and sternotomy in the remaining 6. Results: All the procedures were successfully completed, except for two patients: one died due to ventricular fibrillation after the procedure, and another in the immediate postoperative period due to severe coagulation abnormality. Mean follow-up of the remaining 12 patients was 19 months with favorable outcome. Conclusions: The initial results with the use of a hybrid strategy were satisfactory in terms of survival and improvement of the hemodynamic parameters. The selection of cases, teamwork and appropriate follow-up are key factors to achieve satisfactory results.

ABSTRACT

Congenital heart disease is an important cause of morbidity and mortality in childhood, and in 50% of cases, surgery is required in the first year of life. A high deficit of surgical procedures is estimated in Northern Brazil. Objective: To analyze the waiting time for elective surgical treatment and/ or intervention in children with congenital heart disease in a Cardiology referral center, and to make considerations about heart diseases and forms of treatment in that institution. Methods: A cross-sectional study of all patients aged less than 14 years, with a diagnosis of congenital heart disease that were waiting for elective surgical or percutaneous cardiac treatment. Results: Among the 407 children with congenital heart defects, the most prevalent age group was > 2 to 6 years (34.0%). The average waiting time was 23.1 ± 18.3 months, with a median of 19. The most frequent heart disease was ventricular septal defect (28.98%), patent ductus arteriosus (18.42%) and atrial septal defect (11.05%). Most children (63.4%) were not from the metropolitan area. The percutaneous interventions represented only 27.84% of the catheterization procedures and 14,85% of all heart treatments. Approximately 60% of the pediatric surgeries occurred in children who were not previously registered due to urgency cases. Conclusion: Most of the children waiting for a cardiac procedure were not from the metropolitan area and had malformations potentially treatable by catheterization. It is necessary to increase the capacity of the single referral center in the state of Pará, as well as decentralize the high-complexity cardiological care in the metropolitan region


As cardiopatias congênitas são importantes causas de morbimortalidade infantil e, em cerca de 50% dos casos, é necessária a intervenção cirúrgica no primeiro ano de vida. Estima-se alto défice de procedimentos na Região Norte do Brasil. Objetivo: Analisar o tempo de espera para realização de tratamento eletivo cirúrgico e/ou intervencionista de crianças portadoras de cardiopatias congênitas em um centro de referência cardiológico, e fazer considerações sobre as cardiopatias e suas formas de tratamento na referida instituição. Método: Estudo analítico, de caráter transversal do período de janeiro de 2012 a outubro de 2014, de pacientes com idade igual ou inferior a 14 anos diagnosticados com cardiopatias congênitas que estavam na fila de tratamento cardíaco eletivo cirúrgico ou percutâneo. Resultados: Das 407 crianças que aguardavam por tratamento, a faixa etária mais prevalente foi a de > 2 a 6 anos (34,0%). O tempo médio de espera, em meses, foi 23,1 ± 18,3, com mediana de 19. As cardiopatias mais frequentes foram comunicação interventricular (28,98%), persistência do canal arterial (18,42%) e comunicação interatrial (11,05%). A maioria das crianças (63,4%) não pertencia à região metropolitana. As intervenções percutâneas representaram somente 27,84% do total de cateterismos e 14,85% de todos os tratamentos cardíacos. Cerca de 60% do volume de cirurgias pediátricas ocorreu em crianças sem cadastro prévio no sistema, devido ao caráter de urgência. Conclusão: Grande parte das crianças que aguardam por procedimento cardíaco é procedente de fora da região metropolitana e tem malformações potencialmente tratáveis por cateterismo. É necessário aumentar a capacidade operacional do único centro de referência público do Estado, além de descentralizar o atendimento em alta complexidade cardiológica da região metropolitana

ABSTRACT

Abstract Extracorporeal membrane oxygenation (ECMO) is a well-established tool of cardiopulmonary circulatory support for cardiopulmonary failure in children and adults. It has been used as a supportive strategy during interventional procedures in neonates with congenital heart disease. Herein, we describe a neonate with hypoplastic left heart syndrome who underwent stenting of the Sano shunt and left pulmonary artery after Norwood Sano operation using intra-procedural ECMO support. The use of ECMO as a bridge to recovery might be a feasible and reasonably safe adjunctive approach in the treatment of complications in selective case of neonates having undergone the Norwood Sano procedure.


Resumo A oxigenação por membrana extracorpórea (ECMO) é uma ferramenta bem estabelecida de suporte circulatório em casos de insuficiência em crianças e adultos. A ECMO tem sido utilizada como uma estratégia de suporte durante procedimentos interventistas em recém-nascidos com doença cardíaca congênita. Descrevemos o caso de um recém-nascido com síndrome do coração esquerdo hipoplásico que foi submetido à colocação de um stent em shunt de Sano e artéria pulmonar esquerda após procedimento de Norwood-Sano utilizando-se a ECMO como suporte. O uso da ECMO pode ser uma estratégia adjunta viável e segura no tratamento de complicações em casos eletivos de recém-nascidos submetidos à operação de Norwood-Sano.
