Tetralogy of Fallot (TOF) is the most common, cyanotic congenital heart disease. The hemodynamic changes during pregnancy, with uncorrected TOF, result in serious, life-threatening complications for both patient and baby. The authors report on the successful anesthetic management of a 26-year-old parturient women. The patient was at a gestational age of 33 weeks, with uncorrected TOF. After undergoing a cesarean delivery, she developed intraoperative hypoxia after delivery. We postulated that the patient developed hypoxic Tet spells from hypovolemia, resulting from postpartum bleeding as well as a decrease in her systemic vascular resistance from oxytocin. A multidisciplinary team approach and invasive intraoperative monitoring together with meticulous anesthetic management, were essential for this patient.
