Abstract
OBJETIVO: O objetivo deste trabalho é apresentar os resultados clínicos tardios da plástica da valva mitral com a técnica do "Duplo Teflon". MÉTODOS: A plástica de "Duplo Teflon" consiste em técnica de reparo mitral com ressecção quadrangular da cúspide posterior, anuloplastia segmentar com plicatura do anel com de fios com "pledgets" sobre uma tira de Teflon, e sutura borda a borda da cúspide. Entre abril de 1994 e dezembro de 2003, 133 pacientes com diagnóstico de insuficiência mitral degenerativa com alongamento ou rotura de cordas da cúspide posterior foram submetidos à plástica com esta técnica. A idade média foi de 60,4 anos e 60,9% eram do sexo feminino. Quanto à avaliação clínica no pré-operatório, 29,3% dos pacientes estavam em classe funcional IV, 55,7% em classe III e 15,0% em classe II. Técnicas associadas de plástica mitral foram utilizadas em 15,2% dos pacientes, sendo a mais comum o encurtamento de cordas. Vinte e seis (19,5%) pacientes foram submetidos a operações associadas. RESULTADOS: Houve um (0,75%) óbito hospitalar. No período pós-operatório tardio, 95,5% dos sobreviventes estavam em classe funcional I. As taxas linearizadas de tromboembolismo, reoperação e óbito foram 0,9%, 0,3% e 0,6% pacientes/ano, respectivamente. A sobrevida atuarial em 10 anos foi de 94,1% ± 3,6%. As sobrevidas atuariais livre de tromboembolismo e reoperação foram de 97,3 ± 1,5% e 99,2 ± 0,8%, respectivamente. Não houve casos de endocardite ou hemólise. CONCLUSÃO: A plástica da valva mitral com a técnica do "Duplo Teflon" apresenta baixa morbi-mortalidade e boa evolução clínica tardia.
OBJECTIVE: The purpose of this paper is to present the late clinical results of mitral valve repair with the "Double Teflon" technique. METHODS: "Double Teflon" technique consists of a quadrangular resection of the posterior leaflet, annulus plication with "pledgetted" stitches over a Teflon patch, and leaflet suture. Between 1994 and 2003, 133 patients with degenerative mitral insufficiency due to ruptured or elongated chordae in the posterior leaflet underwent repair with this technique. The mean patient age was 60.4 years and 60.9% patients were male. According to clinical evaluation, 29.3% of the patients were in New York Heart Association functional class IV, 55.7% in class III and 15.0% in class II. Associated techniques of mitral valve repair were used in 15.2% of the patients; the most common was chordal shortening. Twenty six (19.5%) patients had associated procedures. RESULTS: There was one (0.75%) operative death. In the late postoperative period, 95.5% of the surviving patients were in New York Heart Association functional class I. Linearized rates of thromboembolism, reoperation and death were 0.9%, 0.3% and 0.6% patient/year, respectively. The actuarial survival at 10 years was 94.7% ± 3.6%. Actuarial freedom from thromboembolism and reoperation were 97.3 ± 1.5% and 99.2 ±0.8%, respectively. There were no episodes of hemolysis or endocarditis. CONCLUSION: Mitral valve repair with "Double Teflon" technique presents low morbimorbidity and good clinical late evolution.
