Pregnancy in a Patient with Congenital Complete Transposition of Great Arteries after Atrial Switch Operation: A Case Report with a Review of Literatures

Complete transposition of the great arteries (d-TGA) accounting for 5 % of all congenital heart disease (CHD) is one of the most common cyanotic CHDs. Advances in congenital cardiology and surgery improve the prognosis in patients with TGA, nowadays women who survived the disease are entering the child bearing ages. Although, arterial switch operation has been becoming the standard treatment for TGA, atrial switch operation (ASO) was performed till past decades. Right ventricle (RV) becomes to be in charge of systemic circulation in patients with ASO. RV cannot sustain the demands of the systemic circulation and gradually decrease the function. Recently, we have experienced a pregnancy in a patient with congenital TGA treated with ASO. She uneventfully delivered a male neonate weighing of 3100 grams at 38 weeks of gestation. However, she developed the sign of heart failure on four days after delivery. We successfully managed her with administration of oxygen, diuretics and angiotensin converting enzyme (ACE) inhibitor. Herein, we report this case with a review of literatures.
