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.
