目的评价房间隔缺损封堵术后孕妇孕期心功能变化及其对Amplatzer封堵器的影响。方法应用超声心动图观察23例继发孔型房间隔缺损封堵术后孕妇孕期心功能及封堵器位置变化,并与23例正常孕妇对照,评价封堵术后妊娠的安全性。结果与正常孕妇对比,房间隔缺损封堵术后孕妇左房内径在孕初期无变化、孕中期增大但尚在正常值范围、孕晚期则显著增大,左室、右房、右室内径孕期无明显变化,Tei指数孕期均在正常范围。孕期及分娩时房间隔与封堵器黏合紧密、位置未见改变。结论房间隔缺损封堵术后孕妇孕期左房增大对封堵器位置和形态无明显影响,提示封堵术后可安全妊娠与分娩。关键词
Objective To evaluate the changes of cardiac function during pregnancy and its effect on Amplatzer occluder after atrial septal defect closure. Methods Echocardiography was used to observe the changes of cardiac function and location of occluder in 23 pregnant women with secundum atrial septal defect after secundum atrial septal occlusion. Echocardiography was used to evaluate the safety of secundum pregnancy after closure of septum with 23 normal pregnant women. Results Compared with normal pregnant women, the atrial diameter of pregnant women did not change in the first trimester of pregnancy after atrial septal defect occlusion, but increased in the second trimester, but still in the normal range and significantly increased in the third trimester of pregnancy. The left ventricular, right atrium and right ventricular diameter No significant changes during pregnancy, Tei index during pregnancy are in the normal range. Atrial septum and occluder during pregnancy and childbirth close adhesion, the location has not changed. Conclusion After atrial septal defect occlusion, pregnant women with increased left atrium during pregnancy have no significant effect on the location and morphology of the occluder, suggesting safe pregnancy and childbirth after occlusion.
