Congenitally corrected transposition of great arteries (CC-TGA) is an acyanotic congenital heart disease (CHD) with a prevalence of <1% of all CHD. It is characterized by atrioventricular and ventriculoarterial discordance., More than 90% of cases are associated with other cardiac anomalies. Patients with CC-TGA are at increased risk for heart failure as adults due to progressive decline in systemic right ventricular function. Moreover, hemodynamic stress of pregnancy, labor, and delivery may further aggravate the decline.
A 26-year-old acynotic parturient presented to us in 33 weeks of pregnancy for elective cesarean section. Her history revealed CC-TGA with moderate-to-severe pulmonary stenosis (peak gradient 89 mmHg), ventricular septal defect, mild tricuspid regurgitation, and normal ventricular function, shortness of breath on more than regular activity, and history of hypothyroidism. Cardiovascular examination revealed continuous murmur in mitral and pulmonary area and a normal electrocardiograph. All other routine investigations were normal.
Elective cesarean section was planned under sequential spinal-epidural anesthesia. Maintaining strict aseptic precautions, epidural space was identified using the loss of resistance technique with saline followed by a 27G spinal needle at L4–L5 intrathecal space, utilizing a needle-through-needle method (combined spinal-epidural block). Subarachnoid block was given using 5 mg of 0.5% hyperbaric bupivacaine and 25 μg fentanyl. The epidural catheter was then inserted, followed by 20 mg of 0.5% plain bupivacaine. The patient was made to lie in a supine position for 10 min. The block achieved up to the T6 dermatome level.
Intraoperative vitals were maintained throughout with no complications. Postoperative period analgesia was achieved with 0.125% bupivacaine 8 ml and 20 μg of fentanyl through epidural catheter on a demand basis. The postoperative event was uneventful, and the patient was discharged along with her baby 7 days after delivery.
Significant physiological changes occur during pregnancy, which tends to have an adverse outcome in a woman with CC-TGA. Comprehensive preoperative cardiac evaluation is advisable. Neuraxial anesthesia is preferred over general anesthesia to avoid the stress-induced increase in systemic and pulmonary vascular resistance, the myocardial depressant effects of anesthetic agents, and the detrimental effects of positive pressure ventilation. Intrathecal block produces significant hemodynamic compromise, while epidural anesthesia produces a slower, unreliable block, less patient satisfaction, and a significant failure rate.
Anesthetic concerns mainly focused on avoiding the increase in systemic and pulmonary vascular resistance, maintaining the systemic ventricular function, and avoiding air entry into the circulation to prevent paradoxical air embolism. The use of a lower dose of local anesthetic with sequentially combined spinal-epidural; using saline for loss of resistance technique, and strict perioperative vigilance helped us achieve that goal in this patient, and we concur that it might be a good option in parturients with CC-TGA.
