Cirurgia robótica em Cardiologia: um procedimento seguro e efetivo / Robotic surgery in Cardiology: a safe and effective procedure

OBJETIVO: Avaliar os resultados em curto e médio prazo dos pacientes submetidos à cirurgia cardíaca minimamente invasiva robô-assistida. MÉTODOS: De março de 2010 a março de 2013, 21 pacientes foram submetidos à cirurgia cardíaca robô-assistida. Os procedimentos realizados foram: plastia valvar mitral, troca valvar mitral, cirurgia de correção da fibrilação atrial, correção cirúrgica da comunicação interatrial, ressecção de tumor intracardíaco, revascularização do miocárdio totalmente endoscópica e pericardiectomia. RESULTADOS: A idade média foi de 48,39±18,05 anos. O tempo médio de circulação extracorpórea foi de 151,7±99,97 minutos, e o tempo médio de pinçamento aórtico foi de 109,94±81,34 minutos. O tempo médio de intubação orotraqueal foi de 7,52±15,2 horas, sendo que 16 (76,2%) pacientes foram extubados ainda em sala operatória, imediatamente após o procedimento. O tempo médio de permanência em unidade de terapia intensiva foi de 1,67±1,46 dias. Não houve conversões para esternotomia. Não houve óbito intra-hospitalar ou mesmo durante o seguimento em médio prazo dos pacientes. A média do tempo de acompanhamento dos pacientes foi de 684±346 dias, variando de 28 dias a 1096 dias. CONCLUSÃO: A cirurgia cardíaca robô-assistida mostrou-se exequível, segura e efetiva, podendo ser aplicada na correção de diversas patologias intra e extracardíacas.

OBJECTIVE: To evaluate the short and medium-term outcomes of patients undergoing robotic-assisted minimally invasive cardiac surgery. METHODS: From March 2010 to March 2013, 21 patients underwent robotic-assisted cardiac surgery. The procedures performed were: mitral valve repair, mitral valve replacement, surgical correction of atrial fibrillation, surgical correction of atrial septal defect, intracardiac tumor resection, totally endoscopic coronary artery bypass surgery and pericardiectomy. RESULTS: The mean age was 48.39±18.05 years. The mean cardiopulmonary bypass time was 151.7±99.97 minutes, and the mean aortic cross-clamp time was 109.94±81.34 minutes. The mean duration of intubation was 7.52±15.2 hours, and 16 (76.2%) patients were extubated in the operating room immediately after the procedure. The mean length of intensive care unit stay was 1.67±1.46 days. There were no conversions to sternotomy. There was no in-hospital death or deaths during the medium-term follow-up. Patients mean follow up time was 684±346 days, ranging from 28 to 1096 days. CONCLUSION: Robotic-assisted cardiac surgery proved to be feasible, safe and effective and can be applied in the correction of various intra and extracardiac pathologies.

Aneurisma de apêndice de atrial esquerdo gigante / Large left atrial appendage aneurysm

O aneurisma de apêndice atrial esquerdo é uma entidade extremamente rara e diagnosticada, na maioria das vezes, a partir da segunda década de vida, sendo patologia geralmente oligossintomática e diagnóstico de caráter ocasional. Este caso refere-se a um paciente de 21 anos, com quadro de taquicardia supraventricular sustentada sintomática. O diagnóstico foi feito a partir do ecocardiograma transtorácico, após o achado de aumento de área cardíaca em radiografia do tórax. O tratamento cirúrgico é mandadório e o paciente foi submetido à cirurgia para ressecção do apêndice atrial.

Estudo epidemiológico de cardiopatias congênitas na infância e adolescência. Análise em 4.538 casos / Epidemiological study of congenital heart defects in children and adolescents. Analysis of 4.538 cases

OBJECTIVE: To analyze the frequency and prevalence of congenital heart defects in a tertiary care center for children with heart diseases. METHODS: We carried out an epidemiological assessment of the first medical visit of 4,538 children in a pediatric hospital from January 1995 to December 1997. All patients with congenital heart defects had their diagnoses confirmed at least on echocardiography. The frequency and prevalence of the anomalies were computed according to the classification of sequential analysis. Age, weight, and sex were compared between the groups of healthy individuals and those with congenital heart defects after distribution according to the age group. RESULTS: Of all the children assessed, 2,017 (44.4 percent) were diagnosed with congenital heart disease, 201 (4.4 percent) with acquired heart disease, 52 (1.2 percent) with arrhythmias, and 2,268 (50 percent) were healthy children. Congenital heart diseases predominated in neonates and infants, corresponding to 71.5 percent of the cases. Weight and age were significantly lower in children with congenital heart defects. Ventricular septal defect was the most frequent acyanotic anomaly, and tetralogy of Fallot was the most frequent cyanotic anomaly. CONCLUSION: Children with congenital heart defects are mainly referred during the neonatal period and infancy with impairment in gaining weight. Ventricular septal defect is the most frequent heart defect
