Prosthetic mitral valve thrombosis in pregnancy: From thrombolysis to anticoagulation

Introduction: Pregnant women with mechanical prosthetic heart valves are at increased risk for valve thrombosis. Management decisions for this life-threatening complication are complex. Open-heart surgery has a very high risk of maternal mortality and fetal loss. Bleeding and embolic risks associate...
