SummaryBackground: Previously, the high maternal mortality in cardiac patients who became pregnant prompted the assertion: Women with an abnormal heart should not become pregnant. This long-standing notion needs to be revised today.Hypothesis: The study was undertaken to ascertain the experience with a large series of pregnant women with cardiac disease cared for in the same referral center.Methods: From 1989 to 1999, 1,000 pregnant women with heart disease were followed by the same clinical and obstetric team. The cardiac diseases included rheumatic heart disease (55.7%), congenital heart disease (19.1%), Chagas' disease (8.5%), cardiac arrhythmias (5.1%), cardiomyopathies (4.3%), and others (7.3%).Results: Of the pregnant women studied, 765 (76.5%) experienced no cardiovascular events during the study; 235 (23.5%) patients had the following cardiovascular complications: congestive heart failure (12.3%), cardiac arrhythmias (6%), thromboembolism (1.9%), angina (1.4%), hypoxemia (0.7%), infective endocarditis (0.5%), and other complications (0.7%). Clinical treatment allowed adequate management in 161 (68.8%) patients; however, 46 (19.6%) patients underwent interventional procedures because of refractory complications. The general maternal mortality rate was 2.7%. Of the 915 (91.5%) infants who were discharged, 119 (13%) were premature.
Although this monitor had not been calibrated, it showed a tendency for consistent hemodynamic data in obstetric patients and it may be used as a therapeutic guide or experimental tool.
Ao meu marido, Luiz Aparecido Bortolotto Por todo carinho e ajuda na realização deste estudo. A Marco Antonio e Alexandre, meus filhos, pelos momentos roubados e pelo apoio na fase final.
Purpose -Os primeiros relatos de cirurgias cardíacas, realizadas durante a gravidez, surgiram no início da década de 50 1 , ainda no período de cirurgia cardíaca a céu fechado, sem circulação extracorpórea (CEC), observando-se que a mortalidade materna não estava aumentada em relação ao mesmo tipo de cirurgia realizada em não gestantes 2,3 . Entretanto, a mortalidade fetal elevou-se após a introdução da CEC, devida a ocorrência do trabalho de parto prematuro e ao óbito fetal intra-operatório (hipóxia) 4 . Devido ao melhor conhecimento das repercussões fetais, ocasionadas pela CEC, o aprimoramento desta técnica tem determinado a diminuição da mortalidade fetal. O objetivo deste estudo é analisar a evolução materna e fetal de oito gestantes submetidas à cirurgia cardíaca.
MétodosForam analisadas retrospectivamente, oito gestantes submetidas à cirurgia cardíaca sob CEC entre janeiro/86 e dezembro/98. A idade das gestantes variou de 19 a 44 (média de 31,4±7,4) anos. A idade gestacional variou de 12 a 31 (mé-dia de 26,6±7,1) semanas.
