Anesthetic Management of Cesarean Delivery for a Parturient With Dextro-Transposition of the Great Arteries Post-Senning Procedure: A Case Report

The Senning procedure is a palliation technique for addressing dextro-transposition of the great arteries; deoxygenated blood is redirected to the left ventricle, making the right ventricle the systemic ventricle. The physiologic increase in cardiac output during pregnancy may place additional stress on the right ventricle and given the existence of atrial scar tissue, trigger arrythmias. Because the technique was gradually abandoned starting in the 1970s, few remaining patients of child-bearing age remain. We emphasize here the importance of interdisciplinary team planning for delivery. Preparation for possible arrhythmia and potential decompensation in right ventricular function are essential.
