Prenatal Diagnosis and Postnatal Follow-up of congenitally corrected transposition of the great arteries and recurrent supraventricular tachycardia
A 24-year-old woman was referred to our center at 28 weeks’ gestationbecause of suspected fetal cardiac anomalies. We echocardiographically diagnosed ccTGA and additional cardiac anomalies in utero at 28 weeks’ gestation (Gravida: 3 para: 2). Associated cardiac lesions includedventricular septal defect, mild pulmonary valve stenosis, tricuspid valvar displacement and moderate tricuspid regurgitation (Figure –).\nThis fetus experienced supraventricular tachycardia (SVT) in pregnancy (at 35 weeks’ gestation) ().\nThere was no familial history of congenital heart disease. The patient had no known systemic disease. Ultrasonography showed normal fetal growth without any structural anomalies. The diagnosis was confirmed with postnatal echocardiography ().\nPostnatal SVT recurred () electrocardiographic and Holter monitor evidence was confirmed, in which initial treatment with adenosine was ineffective, but amiadarone was effective.
