A 35-year-old woman, gravida 2, para 1, at 24 weeks gestation presents to the clinic for a routine prenatal visit. She has a history of a mechanical aortic valve replacement performed five years ago. Since confirming her pregnancy, her anticoagulation regimen was transitioned to therapeutic-dose enoxaparin. During the visit, the patient appears highly anxious. She states, 'I was reading a natural parenting blog last night, and it said that all injectable medications given during pregnancy cause severe birth defects. I am stopping these injections immediately. From now on, I will only take a daily baby aspirin because it is natural and safe. I know what is best for my baby.'
Which of the following is the most appropriate initial response by the physician?
- I can see that your main priority is keeping your baby safe. Help me understand more about what you read so we can discuss your concerns together.Answer
- BAspirin monotherapy is strictly contraindicated for patients with mechanical heart valves, so we have no choice but to continue your current injections.
- CIf you stop this medication, it constitutes fetal endangerment, and I am legally required by mandatory reporting laws to contact child protective services.
- DBecause you are refusing a life-saving treatment based on an internet blog, I must consult psychiatry to determine if you are legally competent to make this choice.
- EThe medical guidelines for preventing blood clots in pregnant women with mechanical valves mandate the use of injectable anticoagulants; we cannot deviate from this protocol.
