RESUMO
Complex congenital heart disease and pregnancy are a challenge and delicate medical situation. We describe a first-time pregnancy of a woman living with an uncorrected d-transposition of the great arteries (TGA) with serious fetal complications required multidisciplinary assessment. Twenty-six years old primigravida referred to our cardiology center in 34 weeks of gestation with peripheral cyanosis. The patient was stable hemodynamically and the room air oxygen was at 82%. A continuous murmur systolic and diastolic at second left intercostals space was found. The transthoracic echocardiographic showed an uncorrected TGA with a large atrial defect and patent ductus arteriosus. Obstetrical ultrasonography showed severe intrauterine growth restriction. The patient was delivered by caesarean section under epidural anesthesia with good outcome. This is a case report with discussion of the maternal-fetal outcome of pregnant women with asymptomatic uncorrected TGA. Coordinated care by an informed obstetrician and cardiologist should be the aim.
