Abstract

Background

Pregnancy in women with mechanical valves has a high risk of both valve thrombosis and bleeding.

Case summary

We describe the case of a pregnant woman developing thrombosis of a mechanical aortic valve causing severe aortic stenosis without heart failure symptoms. The pregnancy was managed with heparin, and a high dose of warfarin was restarted soon after delivery. One month later transesophageal echocardiogram showed dissolution of the thrombosis, with restoration of the transvalvular gradients present after implantation.

Conclusion

The management of pregnant patients with mechanical valves is complex and a multidisciplinary approach is essential.

病例报告妊娠期机械主动脉瓣血栓形成的处理方法

病例摘要我们描述了一例孕妇因主动脉瓣机械瓣膜血栓形成导致主动脉瓣严重狭窄而无心力衰竭症状的病例。孕妇在妊娠期使用肝素进行治疗，分娩后不久重新开始使用大剂量华法林。一个月后，经食道超声心动图显示血栓溶解，植入后的跨瓣梯度恢复。
