ABSTRACT

Introduction: valve disease is an important cause of heart failure. There is a direct relationship between valve deterioration and the patient’s inflammatory status and cytokines: interleukin-6, interleukin-1, tumor necrosis factor, and C-reactive protein, involved in this major state of inflammation. Objective: to report a series of cases of valve replacement, using a bioprosthetic or mechanical valve, and the inflammatory profile of them. Methods: patients older than 18 years and with bioprosthetic or mechanical valve placed for a minimum of 6 months and maximum of 2 years were included. In addition to the demographic characteristics of each patient, inflammatory markers were measured and a comparison was made of echocardiographic results before (based on medical records) and after surgery. A total of 46 patients were enrolled, 23 with mechanical valve and 23 with bioprosthetic valve. Results: of the 46 patients, 20 presented complete data were included, 12 with bioprosthetic and 8 with mechanical valve. There was no difference between types of prosthesis or implant site for the values of inflammatory markers although they were all above reference range. Discussion: patients undergoing aortic mechanical valve implant benefited more than those undergoing bioprosthetic implant and both with much better results than those of valve replacements performed on mitral valve. In short, there was no difference in relation to inflammatory biomarkers. .


Introdução: doença valvar é importante causa de insuficiência cardíaca. Existe relação direta entre a deterioração valvar e o estado inflamatório do paciente, sendo as citocinas interleucina-6, interleucina-1, fator de necrose tumoral e a proteína C reativa as principais envolvidas nesse estado de estimulação. Objetivo: relatar uma série de casos de troca valvar, bioprótese ou mecânica e seu perfil inflamatório. Métodos: pacientes maiores de 18 anos e portadores de bioprótese ou protética mecânica, com período mínimo de 6 meses e máximo de 2 anos, foram incluídos. Além das características demográficas de cada paciente, colheram-se os marcadores inflamatórios e comparou-se o ecocardiograma conforme registro de prontuário antes e depois da cirurgia. Um total de 46 pacientes foi incluído, tendo sido 23 com valva mecânica e 23 de bioprótese. Resultados: dos 46 pacientes, chegamos ao total de 20 pacientes com dados completos, sendo 12 com bioprótese e 8 com protética mecânica. Não houve diferença entre tipo de prótese ou local de implante para os valores dos marcadores inflamatórios, contudo, na média, seus valores estavam aumentados. Discussão: pacientes submetidos ao implante de valva protética mecânica aórtica beneficiaram-se mais do que os submetidos ao implante de bioprótese e ambos com resultado bem superior às trocas realizadas na valva mitral. Não houve diferença em relação aos biomarcadores inflamatórios. .
