Abstract

Abstract Background: Rheumatic carditis is a challenge for treatment and secondary prophylaxis, due to severe valve sequelae. Objective: To evaluate the cases of rheumatic carditis in patients under 18 years old treated with corticosteroids. Methods: An observational, longitudinal and retrospective study was carried out on the profile of patients, in the period of 2000-2015. We selected those who received corticosteroid therapy at immunosuppressive doses, for the treatment of carditis and were aged 5 to 18 years. Data were extracted from medical records. Calculations of: averages, standard deviations, medians and interquartile ranges, ratios and 95% confidence intervals were obtained. Chi-square and Wilcoxon tests were applied for comparisons. The level of significance was 5%. Results: Of the 93 cases, 93.53% developed moderate or severe carditis. Mitral regurgitation was detected in 100% of the sample. Pulse therapy was administered in 11.83%. Surgery was performed in 23.69% of patients: mitral, aortic and/or tricuspid valve repair or replacement. The evolution of the cases was favorable in 70.96%. There was a good response among those who received only clinical treatment and those who belonged to the surgical group. The comparison of the initial and posterior valve lesions to the corticoid use was statistically significant (p < 0.001). A difference between the ejection fraction medians was observed (p = 0.048). Hospitalization was required twice or more for 45.16% of the patients. The mortality rate was 5.38%. Conclusions: The patients showed significant clinical improvement. The treatment was effective, reducing trivalvular impairment.

Plastia mitral cirúrgica em crianças com febre reumática

Andréa Rocha e Silva, Gesmar Herdy, Alan Araújo Vieira … (2009)

FUNDAMENTO: A reconstrução mitral é bem aceita em crianças com febre reumática. OBJETIVO: Analisar os resultados da reconstrução cirúrgica mitral, em crianças com lesões reumáticas, após quatro anos de evolução. MÉTODOS: Estudo retrospectivo de 40 pacientes menores de 18 anos, operados no Instituto Nacional de Cardiologia (RJ), entre janeiro de 1998 e janeiro de 2003. Foram analisados o grau da regurgitação mitral pelo ecocardiograma, a técnica cirúrgica, a classe funcional pré e pós-operatória, a evolução dos casos, a necessidade de troca valvar e óbitos. RESULTADOS: Vinte e um pacientes (52,5%) eram do sexo feminino. A insuficiência mitral era grave em 32 pacientes (80%) e moderada em oito (20%). Ocorreram três óbitos imediatos (7,5%). Após três meses da cirurgia, o ecocardiograma demonstrou que em 35 de 37 casos (94,6%) não havia regurgitação valvar ou essa era leve, e em dois pacientes (5,2%) era grave. A classe funcional no pré-operatório era III e IV em 33 casos (82,5%) e, três meses após a cirurgia, todos os 37 casos (100%) estavam em classe funcional I e II. A diferença entre os dados do grau de regurgitação mitral e classe funcional no pré e no pós-operatório foram estatisticamente significativos (p<0,01). A troca valvar antes de quatro anos de evolução ocorreu em sete (19%) dos casos. CONCLUSÃO: A reconstrução da valva mitral mostrou resultado favorável na maioria dos casos, ao considerarmos o grau de regurgitação mitral e a classe funcional pré e pós-cirúrgica e, somente 19% dos pacientes vieram a necessitar da cirurgia para troca valvar antes de quatro anos de evolução.
