Evolução Tardia das Próteses Biológicas e Mecânicas em Posição Aórtica

Abstract: Fundamento: Apesar da constante renovação e do aprimoramento das próteses valvares cardíacas, a decisão sobre substituição por prótese biológica ou mecânica permanece controversa. Objetivo: Comparar pacientes submetidos à cirurgia para troca valvar aórtica utilizando substituto biológico ou mecânico. Métodos: Estudo observacional, do tipo coorte histórica por análise de prontuário. Foram selecionados 202 operados entre 2004 e 2008, com seguimento médio de 10 anos. O nível de significância estatística adotado f… Show more

“…We found only 1 contribution that evaluated sB-AVR in a comparison to sM-AVR in a group of patients with a mean age 50 years. Bruscky et al [ 25 ] were the first to show that sM-AVR resulted in a significantly better outcome when looking at a combined end point of survival and reoperation. Our results support this observation in a larger cohort and we furthermore extend our results by reporting mortality probabilities after reoperation, which was estimated to be 34% after 10 years over both groups.…”
