“…The linearized rate of reoperation found of 3.5% patients-years was similar to the literature [11] and higher when compared to patients with degenerative etiology [23]. A higher linearized rate of reoperation is expected, since the rheumatic etiology is a risk factor for reoperation due to outbreaks of rheumatic fever, which continually provoke structural changes in the mitral valve apparatus [24].…”

Objective: Mitral valve repair in rheumatic patients is still a challenge. The aim of this study is to assess the results of mitral valve repair in rheumatic patients with rheumatic mitral insufficiency.Methods: 330 patients with rheumatic mitral insufficiency who had undergone mitral valve repair in the Heart Institute HC-FMUSP were assessed retrospectively, between 1985 and 2005. The mean age was 26.9 ± 15.4 years and 57.6% were female. On preoperative assessment, 39.5% of patients were in NYHA functional class IV. The most common techniques for repair employed were bovine pericardial strip annuloplasty in 48.4% patients and Carpentier ring annuloplasty in 22.6%. Shortening of chordae (20%) and papillary muscle splitting (17.8%) were the most common associated techniques performed. Tricuspid valve repair (26.7%) and aortic valve replacement (27.2%) were the most common associated procedures.Results: The hospital mortality was 0.9% (three patients), two of them children with active rheumatic fever. Linearized rates of thromboembolism, endocarditis, reoperation and late death were 0.2%, 0.2%, 3.5% and 0.5% patients-year, respectively. Actuarial survival in 20 years was 86.4 ± 6.6%.

“…Brandão et al [ 8 ] obtained excellent clinical results from mitral valvuloplasty by means of the double Teflon technique, over a 10-year follow-up period. The actuarial survival rate was 94.1±3.6%, the survival rate free from thromboembolism was 97.3±1.5% and the survival rate free from reoperation was 99.2±0.8%.…”

“…In Brazil, Pomerantzeff et al [ 6 ] developed a technical modification in which threads with "pledgets" on a Teflon flap were used for segmental plication of the posterior ring corresponding to the segment removed from the cuspid, without using a prosthetic ring. This technique, named the "double Teflon technique", has presented excellent long-term results, with low morbidity and mortality rates [ 7 , 8 ] .…”

IntroductionMitral valve repair is the treatment of choice to correct mitral insufficiency, although the literature related to mitral valve annulus behavior after mitral repair without use of prosthetic rings is scarce.ObjectiveTo analyze mitral annulus morphology and function using real time tridimensional echocardiography in individuals submitted to mitral valve repair with Double Teflon technique.MethodsFourteen patients with mitral valve insufficiency secondary to mixomatous degeneration that were submitted to mitral valve repair with the Double Teflon technique were included. Thirteen patients were in FC III/IV. Patients were evaluated in preoperative period, immediate postoperative period, 6 months and 1 year after mitral repair. Statistical analysis was made by repeated measures ANOVA test and was considered statistically significant P<0.05.ResultsThere were no deaths, reoperation due to valve dysfunction, thromboembolism or endocarditis during the study. Posterior mitral annulus demonstrated a significant reduction in immediate postoperative period (P<0.001), remaining stable during the study, and presents a mean of reduction of 25.8% comparing with preoperative period. There was a significant reduction in anteroposterior and mediolateral diameters in the immediate postoperative period (P<0.001), although there was a significant increase in mediolateral diameter between immediate postoperative period and 1 year. There was no difference in mitral internal area variation over the cardiac cycle during the study.ConclusionSegmentar annuloplasty reduced the posterior component of mitral annulus, which remained stable in a 1-year-period. The variation in mitral annulus area during cardiac cycle remained stable during the study.

“…A idade avançada e a não estimulação atrial foram fatores preditivos independentes para a ocorrência dessa arritmia (25) . A plástica da valva mitral com a técnica do "duplo Teflon" mostrou baixa morbimortalidade e boa evolução clínica tardia (26) . As estratégias de uso de antifibrinolíticos, hemodiluição normovolêmica e reposição total do perfusato reduziram a necessidade de hemotransfusão no pós-operatório de cirurgia cardíaca (27) .…”

RESUMoEsta nova série de artigos tem por objetivo levar aos leitores nacionais e internacionais algumas das mais importantes contribuições provenientes da literatura médica brasileira recente. Embora possa parecer que não tenham relação direta com a Medicina do Exercício e do Esporte, são trabalhos que podem oferecer suporte a muitas linhas de pesquisa nessa área. Os artigos originais mais relevantes são selecionados por experientes editores, a quem solicitamos que escolham palavras-chave para que sejam destacadas para chamar a atenção do leitor. Para facilitar a leitura, os artigos são organizados por área de interesse. Para aproveitar ao máximo o limitado espaço editorial, não são incluídos os nomes dos autores dos artigos. Entretanto, a referência completa é oferecida ao final do artigo. O resultado final traz o que há de melhor do artigo, seguido de uma sintética interpretação pessoal. Endereçado ao médico ocupado, esperamos que esta inciativa possa contribuir para o sucesso da translação do conhecimento da evidência científica para a prática clínica. Palavras-chave: medicina esportiva, cardiologia, ortopedia, nutrição. aBStRaCtThis brand-new series of articles aims at delivering to national and international readers some of the cutting-edge contributions from the Brazilian medical literature. Some of them may not be directly related to the area, but they can be the grounding for scientific research in the field of Sports and Exercise Medicine. Recently, papers published in the main Brazilian medical journals are carefully selected and analyzed by skilled medical editors. In addition, we asked editors to choose keywords to be highlighted in order to call the reader' s attention. Articles are organized by area of interest to facilitate reading. To get the most of the limited available editorial space we did not include the names of the authors of the related articles in the text itself, but a complete reference guide is provided at the end of the article. The result carries the best from the original paper accompanied by a personal interpretation. Directed to the busy medical doctor, we hope that this initiative may contribute to the successful translation of knowledge from scientific evidence to clinical practice.
