INTRODUCTION: Pregnancy increases the risk of mechanical heart valve (MHV) thrombosis. Warfarin is protective, but implies risks to the fetus. Unfractionated heparin (UFH) is less effective but does not harm the fetus. In general, anticoagulation is more stable and predictable with low molecular weight heparin (LMWH) than with UFH. METHOD: ...

Inherited thrombophilia is recognized as one of the causes of recurrent fetal loss. Yet, the risk of fetal loss in women with thrombophilia is far from absolute. Other risk modifiers are clearly involved, but remain to be identified. The mechanism that translates maternal thrombophilia into pregnancy disorder is also not ...
Goodman Chelsi - - 2009
PROBLEM: We have previously reported the role of polymorphisms of thrombogenic genes involved in coagulation and fibrinolysis as risk factors for recurrent pregnancy loss. Thrombophilia has been viewed as a multigenic disorder rather than a monogenetic clinical phenotype and Apo E has been shown to play an important role in ...

Pregnancy in women with mechanical valve prostheses has a high maternal complication rate including valve thrombosis and death. Coumarin derivatives are relatively safe for the mother with a lower incidence of valve thrombosis than un-fractionated and low-molecular-weight heparin, but carry the risk of embryopathy, which is probably dose-dependent. The different ...

Women with familial hypercholesterolemia (FH) should be treated effectively during pregnancy, as elevated low-density lipoprotein cholesterol (LDL-C) levels may result in life-threatening consequences. Hydroxymethylglutaryl-coenzyme A reductase inhibitors are contraindicated during pregnancy, therefore LDL apheresis should be considered in the management of such pregnant cases. There are five different methods of ...
