风湿性心脏病的孕妇近数十年来有所增加。这是因为:(1)风湿热病例的生存率改善;(2)感染性心内膜炎的病例的预后较前为好;(3)孕后因风湿性心脏病而需流产者减少;(4)分娩时孕妇因风心病而死亡者减少,从30/10万降为4/10万(人次/分娩)。引起风心病母亲死亡率下降的因素有:(1)诊断技术改善;(2)处理改善;(3)心脏手术治疗;(4)长期抗生素预防,心脏严重损害的病例数减少。特别是孕前和妊娠期的医学监测是重要的决定因素。因而在妊娠期突出表现风湿性心脏病的孕妇增加。风湿性心脏病孕妇如发生充血性心衰,母亲死亡率33％,充血性心衰的发生率随母亲年龄而增加,经产妇较初产妇多见,并且直接与风湿过程的时间而异。预后取决于(除二尖瓣狭窄外)心脏扩大的程度;新近风湿热发作和既往心衰史,预后和心功能有关。未孕前心脏功能Ⅰ、Ⅱ级者预后良好,除常规产前护理外几乎不需特殊处理,而Ⅲ、Ⅳ级者则合并症和死亡率增高,需要严格的内科监视和产科共同管理。心脏病孕妇的胎儿损失率常受药物治疗影响,孕妇动脉血氧饱和度在80％以下者有发生流产、早产、或胎儿宫内生长迟缓的倾向。预后不良。心脏瓣膜损害主要是二尖瓣病和主动脉瓣病。二尖瓣狭窄占60～70％,二尖瓣关闭不全占25％,主动 Pregnant women with rheumatic heart disease have increased in recent decades. This is because: (1) the survival rate of rheumatic fever cases improved; (2) the prognosis of infective endocarditis cases better than before; (3) postpartum due to rheumatic heart disease need to reduce abortion; ( 4) The number of pregnant women who died from rheumatic heart during childbirth decreased from 30/10 to 4/10 (births / birth). The factors contributing to the decline of maternal mortality in rheumatic heart disease include: (1) improvement of diagnostic techniques; (2) improvement of treatment; (3) cardiac surgery; (4) reduction of long-term antibiotic prevention and serious heart damage. Medical monitoring, especially before and during pregnancy, is an important determinant. Thus highlighting pregnant women during pregnancy increased rheumatic heart disease. Congestive heart failure in pregnant women with rheumatic heart disease such as congestive heart failure, maternal mortality rate of 33%, the incidence of congestive heart failure increased with the age of mothers, prevalent maternal mothers more common and directly with the rheumatic process time varies. The prognosis depends on the extent of heart enlargement (except mitral stenosis); recent episodes of rheumatic fever and previous history of heart failure, prognosis, and cardiac function. Pre-pregnancy cardiac function Ⅰ, Ⅱ grade prognosis is good, with the exception of conventional prenatal care almost no special treatment, and Ⅲ, Ⅳ grade complications and mortality increased, requiring strict medical surveillance and obstetric co-management. Fetal heart failure rate of fetal loss often affected by drug treatment, pregnant women with arterial oxygen saturation of 80% of those who have abortion, premature birth, or fetal growth retardation tendency. Poor prognosis. Heart valve damage is mainly mitral valve disease and aortic valve disease. Mitral stenosis accounted for 60 to 70%, mitral regurgitation accounted for 25%, active
