AbstractWe report a case of a woman who became pregnant after the diagnosis of moderate to severe pulmonary hypertension and underwent successful full-term pregnancy. Pulmonary hemodynamics were monitored before pregnancy and in the peripartum period. The patient was followed closely by the cardiology and high-risk obstetric specialists in the outpatient setting until she underwent c-section with epidural anesthesia. Outpatient medical management included twice daily subcutaneous enoxaparin and once daily amlodipine. Immediately prior to cesarian section, and for several days postoperatively, invasive hemodynamic monitoring was employed to titrate medical therapy. During delivery, strict attention focused on limiting intravenous fluids in order to avoid right ventricular volume overload. The postoperative course was complicated by a spontaneous, acute rise in pulmonary vascular resistance, which was managed with intravenous epoprostenol. In addition, abdominal bleeding, likely related to postoperative anticoagulation and platelet dysfunction, was controlled with transfusion and spontaneously resolved after discontinuing the anticoagulation. This case presents a favorable outcome in a pregnant patient undergoing cesarian section despite several complications related to pulmonary hypertension and right ventricular dysfunction, which are often fatal.2007 S.
