Implication
Supports tailored regimens by thrombotic-fetal risk in mechanical valve pregnancies; extends evidence on anticoagulation complications.
Key Points
- To evaluate the safety and efficacy of warfarin, unfractionated heparin, and low-molecular-weight heparin in pregnant women with mechanical prosthetic heart valves.
- Searched MEDLINE from 1966 to October 2003 for English and non-English literature evaluating anticoagulation therapy during pregnancy.
- Identified and selected clinical studies with a specific focus on pregnant women with mechanical prosthetic heart valves.
- Both oral anticoagulants (warfarin) and injectable heparins (unfractionated and low-molecular-weight) demonstrated significant potential for maternal and fetal complications.
- Tailored therapeutic regimens stratified by maternal thrombotic and fetal risk profiles were established to optimize clinical outcomes and minimize adverse events.
