The optimal anticoagulation therapy for pregnant patients with a mechanical
valve prosthesis is uncertain, but teratogenic effects and the high
incidence of fetal loss associated with dicumarol derivatives limit the use
of these agents as anticoagulants in this setting. A patient with a
mechanical valve prosthesis, in the first trimester of pregnancy, stopped
taking her warfarin because of personal fears about teratogenicity.
Prosthetic valve thrombosis developed, and she required redo mitral valve
replacement. Another mechanical prosthesis was inserted without maternal or
fetal injury. The patient was maintained on continuous home, intravenous,
high-dose heparin therapy for the remainder of her pregnancy. This therapy
resulted in a successful pregnancy and delivery without valve thrombosis,
hemorrhagic events, or maternal or fetal compromise.
