AbstractA 35-year-old twin primigravida with aortic stenosis underwent cesarean section under epidural anesthesia. She had her ventricular septal defect repaired at 3 years of age. Preoperative ultrasonic study revealed severe aortic stenosis in which valve area was 0.77 cm2 and pressure gradient between the left ventricle and the aorta was 80 mmHg. We persuaded her and her husband to discontinue pregnancy and recommended aortic valve replacement surgery. They rejected our suggestions, and cesarean section was scheduled at 29 weeks' gestation. We chose epidural anesthesia. A 20-gauge catheter and a pulmonary artery catheter were inserted to monitor the hemodynamics. Two lumbar epidural catheters were placed at the L 1-2 and L 4-5 intervertebral spaces. Sixteen milliliters of 1.5% mepivacaine were injected, producing anesthesia up to T 6 level. The babies were delivered, and postnatal conditions of both infants were satisfactory. Methoxamine 1 mg was administered four times when systolic blood pressure decreased to 80 mmHg following deliveries. Otherwise, peripartal hemodynamics was stable, and she was transferred to the intensive care unit (ICU). Postoperative pain was controlled with epidural infusion of fentanyl. She did not complain of chest pain perioperatively and was discharged from the ICU next day.
