The Safety and Efficacy of Low-Molecular-Weight Heparin in Pregnant Women With Rheumatic Heart Disease and Valves Replacement.

Summary: Pregnant women who have had heart valve replacements face a high risk of blood clots. To stay safe, they need blood thinners. Doctors often use a drug called LMWH, but it isn't officially approved for this specific use yet. A large study looked at 744 pregnancies to see if LMWH works well. They found that women taking LMWH had very few blood clots or bleeding issues. The babies were completely safe, too! This proves LMWH is a safe and helpful choice to protect these mothers and their babies.
