Tratamento cirúrgico da fibrilação atrial por isolamento da parede posterior do átrio esquerdo em doentes com valvopatia mitral reumática crônica: um estudo randomizado com grupo controle Surgical treatment of atrial fibrillation through isolation of the left atrial posterior wall in patients with chronic rheumatic mitral valve disease: a randomized study with control group

OBJETIVO: Determinar a efetividade do isolamento cirúrgico da parede posterior do átrio esquerdo envolvendo os óstios das veias pulmonares, no tratamento da fibrilação atrial de etiologia reumática. MÉTODOS: Estudo prospectivo e randomizado envolvendo portadores de valvopatia mitral reumática, fibrilação atrial persistente com duração < a 6 meses, idade < a 60 anos e diâmetro atrial esquerdo < a 65 mm. Os pacientes foram distribuídos aleatoriamente em dois grupos: tratamento cirúrgico valvar (grupo controle) e tratamento cirúrgico valvar associado ao isolamento da parede posterior do átrio esquerdo mediante técnica de "corte e sutura" (grupo tratado). RESULTADOS: Foram operados 29 indivíduos, sendo que 27 (13 do grupo controle e 14 do grupo tratado), foram acompanhados regularmente. Os pacientes dos dois grupos não diferiram em relação às suas características basais. O tempo de seguimento médio foi de 11,5 meses no grupo controle e de 10,3 meses no grupo tratado. As freqüências cumulativas de pacientes livres de fibrilação atrial foram significativamente maiores no grupo tratado tanto na fase peri-operatória (p= 0,0035) quanto na fase tardia (p= 0,0430). CONCLUSÃO: O isolamento cirúrgico da parede posterior do átrio esquerdo envolvendo os óstios das veias pulmonares é uma forma efetiva de tratamento da fibrilação atrial na valvopatia mitral reumática.<br<OBJECTIVE: To determine the effectiveness of surgical isolation of the left atrial posterior wall encompassing the ostia of the pulmonary veins for the treatment of atrial fibrillation of rheumatic etiology. METHODS: Prospective and randomized study of patients with rheumatic mitral valve disease, persistent atrial fibrillation for 6 months or longer, age < 60 years, and left atrial diameter < 65 mm. The patients were randomly distributed into 2 groups as follows: surgical valvular treatment (control group) and surgical valvular treatment associated with isolation of the left atrial posterior wall according to the "cut-and-sew" technique (treated group). RESULTS: Twenty-nine individuals were operated upon, 27 of whom (13 in the control group and 14 in the treated group) were regularly followed up. The patients of both groups did not differ in regard to their basal characteristics. The mean follow-up time was 11.5 months in the control group and 10.3 months in the treated group. The cumulative frequencies of the patients without atrial fibrillation were significantly greater in the treated group both in the perioperative (P=0.0035) and late (P=0.0430) phases. CONCLUSION: Surgical isolation of the left atrial posterior wall encompassing the ostia of the pulmonary veins is an effective form of treating atrial fibrillation in rheumatic mitral valve disease.

abstract	OBJETIVO: Determinar a efetividade do isolamento cirúrgico da parede posterior do átrio esquerdo envolvendo os óstios das veias pulmonares, no tratamento da fibrilação atrial de etiologia reumática. MÉTODOS: Estudo prospectivo e randomizado envolvendo portadores de valvopatia mitral reumática, fibrilação atrial persistente com duração < a 6 meses, idade < a 60 anos e diâmetro atrial esquerdo < a 65 mm. Os pacientes foram distribuídos aleatoriamente em dois grupos: tratamento cirúrgico valvar (grupo controle) e tratamento cirúrgico valvar associado ao isolamento da parede posterior do átrio esquerdo mediante técnica de "corte e sutura" (grupo tratado). RESULTADOS: Foram operados 29 indivíduos, sendo que 27 (13 do grupo controle e 14 do grupo tratado), foram acompanhados regularmente. Os pacientes dos dois grupos não diferiram em relação às suas características basais. O tempo de seguimento médio foi de 11,5 meses no grupo controle e de 10,3 meses no grupo tratado. As freqüências cumulativas de pacientes livres de fibrilação atrial foram significativamente maiores no grupo tratado tanto na fase peri-operatória (p= 0,0035) quanto na fase tardia (p= 0,0430). CONCLUSÃO: O isolamento cirúrgico da parede posterior do átrio esquerdo envolvendo os óstios das veias pulmonares é uma forma efetiva de tratamento da fibrilação atrial na valvopatia mitral reumática.<br<OBJECTIVE: To determine the effectiveness of surgical isolation of the left atrial posterior wall encompassing the ostia of the pulmonary veins for the treatment of atrial fibrillation of rheumatic etiology. METHODS: Prospective and randomized study of patients with rheumatic mitral valve disease, persistent atrial fibrillation for 6 months or longer, age < 60 years, and left atrial diameter < 65 mm. The patients were randomly distributed into 2 groups as follows: surgical valvular treatment (control group) and surgical valvular treatment associated with isolation of the left atrial posterior wall according to the "cut-and-sew" technique (treated group). RESULTS: Twenty-nine individuals were operated upon, 27 of whom (13 in the control group and 14 in the treated group) were regularly followed up. The patients of both groups did not differ in regard to their basal characteristics. The mean follow-up time was 11.5 months in the control group and 10.3 months in the treated group. The cumulative frequencies of the patients without atrial fibrillation were significantly greater in the treated group both in the perioperative (P=0.0035) and late (P=0.0430) phases. CONCLUSION: Surgical isolation of the left atrial posterior wall encompassing the ostia of the pulmonary veins is an effective form of treating atrial fibrillation in rheumatic mitral valve disease.
