INTRODUCTION AND IMPORTANCEPregnant women under warfarin for mechanical heart valves can pose a variety of challenges which requires fine tuning of various anticoagulants throughout the pregnancy and in the postpartum period as hemorrhage can lead to maternal and fetal morbidity and mortality. CASE PRESENTATIONA 36-year-old woman gravida two, para one at 35 weeks 5 days gestation, with hypothyroidism with mitral valve replacement and tricuspid valve repair due to rheumatic heart disease underwent emergency lower section cesarean section for fetal bradycardia. B-lynch suturing was eventually done to control atonic postpartum hemorrhage. During hospital stay she developed surgical site infection of abdominal skin incision site which was also subsequently managed. Postpartum anticoagulation was started late due to postpartum hemorrhage and finally the patient was discharged on warfarin. CLINICAL DISCUSSIONThere is always a risk of both thromboembolic and hemorrhagic manifestations in a pregnant woman with a prosthetic heart valve which requires fine tuning of anticoagulants throughout the pregnancy and in the postpartum period. Hemorrhagic manifestation in the form of postpartum hemorrhage is common which can be difficult to manage and also poses a great dilemma in restarting the anticoagulation after delivery. Excessive blood loss can itself lead to mortality and morbidity, and also via increased risk of surgical site infection. CONCLUSIONAppropriate preconception counseling along with meticulous assessment, management and monitoring of pregnant women with prosthetic heart valves is necessary to decrease fetal and maternal morbidity and mortality.
