RESUMO
Objetivo - Avaliar a valvoplastia mitral por duplo cateter-baläo como técnica alternativa näo cirúrgica para tratamento da estenose mitral reumática. Método - Duzentos pacientes foram submetidos ao procedimento, sendo 86,5% do sexo feminino, com idade média de 35,2 anos. Oitenta e um por cento estavam em classes funcionais III e IV (NYHA), e 4% exibiam ritmo de fibrilaçäo atrial. Quatro por cento foram submetidos à comissurotomia cirurgica prévia e 7% eram gestantes. Utilizou-se a técnica de dilataçäo com duplo cateter-baläo, após punçäo septal esquerda. Resultados - O procedimento foi realizado com sucesso em 89% dos pacientes. A área valvar mitral aumentou de 0,91 ñ 0,27 para 2,10 ñ 0,47 cm*, p < 0,001; ocorreu reduçäo do gradiente transvalvar mitral de 20,86 ñ 6,16 para 4,26 ñ 3,13 mmHg, p < 0,001; as pressöes do átrio esquerdo e do tronco da artéria pulmonar reduziram de 25,90 ñ 7,10 para 12,10 ñ 9,0 mmHg e de 36,47 ñ 12,93 para 24,56 ñ 9,98 mmHg, p < 0,001, respectivamente. Dos 21 casos com insucesso, em 19 ocorreram dificuldades com a técnica transeptal. Em 12, constataram-se graus distintos de derrame pericárdico, dos quais 6 exibiram sinais de tamponamento cardíaco. Os 21 casos foram operados, ocorrendo 1 óbito. O refluxo mitral aparece em 50 casos e aumentou em 8. Quinze destes casos, exibiram descompensaçäo clínica, dos quais 10 foram operados, 3 estäo sob controle clínico e 2 faleceram tardiamente. Conclusäo - A valvoplastia mitral pelo duplo cateter-baläo é técnica segura, com bons resultados, constituindo-se me procedimento terapêutico alternativo näo cirúrgico da estenose mitral
ABSTRACT
Purpose - To study the immediate clinical, echocardiographic and hemodynamic results Of 200 patients who underwent percutaneous mitral balloon valvotomy (PMV) with double balloon technique. Methods - Two hundred patients were submitted to PVM for treatment of congestive heart failure secondary to severe mitral stenosis, between August 1987 to July 1991. Their mean age was 35.2 years, and 86.5% were female patients 81% of them was in functional class, New York Heart Association (NYHAJ III or IV; 4% was in atrial fibrilation and 4% had previous surgical commissurotomy. Results - PMV was successfully performed in 89% of the patients. The mitral valve area, by pressure half time method, increased from 0.91 ± 0.27 to 2.10 ± 0.47 cm2, p < 0.001; the mean mitral gradient decreased from 20,86 ± 6.16 to 4.26 ± 3.13 mmHg, p < 0.001; the left atrium and mean pulmonary artery pressure decreased from 22.3 ± 7.1 to 11.9 ± 8.3 and 36.47 ± 12.93 to 24.56 ± 9.98 mmHg, p < 0.001, respectively. Complications related to transeptal technique occurred in 12 patients, which resulted in cardiac tamponade in 5 and death in 1. In 19 patients the punction of the atrial septum could not be performed. Mitral regurgitation (MR) immediately after PMV appeared 1 + or more grade in 50 patients, increased in 8 patients and remained unchanged in 11 patients. Ten patients needed mitral valve replacement in the first 48h after PMV, for treatment of severe MR. Conclusion - PMV prod uces excellent immediate results and can be considered an alternative to surgery for the relief of mitral stenosis
